Each floor measures 200 feet by 200 feet and the floors 12 Mare divided into as many as four separate spaces with the smallest 13 Ilbeing 3,500 square feet. Each floor is served by one egress stair. 14 IIThe effective travel distance from the most remote area to the stairs 15 11 is 380 feet. 16 . A second stairwell would be difficult to construct due 17 to the Buildings location on the property, the dock arrangement, the 18 nature of the use of the Building (cold storage) and the thickness of 19 the walls, 46 inches. 20 • From the 6th floor a person could safely exit the 21 Building in 4 minutes 18 seconds. The total elapsed time from ignition 22 to when a smoke layer from a fire involving the frozen commodity 23 descends to a point 6 feet above the floor in the smallest storage room 24 is 8 minutes 10 seconds. On an undivided floor, the same conditions 25 are not reached until 72 minutes 36 seconds. 26 • Second floors of any use with an occupant load of less 27 than 10 are permitted to have only one exit, pursuant to California 28 Code of Regulations, Title 24, Part 2, Section 1004.2.3.2 and Table - 3 - 4 a i 1 10A. An aviation control tower with an occupant load of 15 per floor 2 and a maximum area of 1,500 square feet is permitted to have only one 3 exit even though it may be unlimited height when of type I-FR 4 construction. The subject building can be classified as type I-FR and 5 the actual occupant load due to the nature of the operations and 6 environmental conditions is approximately 1 per floor. 7 • warehousemen are intimately familiar with the building 8 geography and _are equipped with and trained in the use of an emergency 9 escape mask, which provides them up to 20 minutes of escape time 10 through even poisonous gas clouds. 11 . There is a written procedure whereby the stair doors in 12 each level are inspected and logged daily to ensure they are not 13 blocked or closed by ice or other obstructions. 14 • All employees are trained to deal with an ammonia 15 release as required by the Hazardous Materials Management Plan and the 16 Risk Management Plan and Prevention Plan which is on file with the 17 City. All warehousemen at this facility are provided with and trained 18 in the use of a two-way transceiver. 19 • The likelihood of a release is minimal because of the 20 piping arrangement and the way the evaporators are suspended. The 21 mounting is flexible which allows movement without damage. Any 22 significant leak of ammonia will be detected by `the ammonia detection 23 system, which automatically cuts off the feed to the entire warehouse 24 and transmits an alarm to an attended location. Additionally, the 25 ammonia system operates at a below atmospheric pressure (vacuum) of 26 approximately 6 inches. Under the unlikely scenario that if a 1/32 of 27 an inch crack in the piping occurred and the leak went undetected, the 28 piping system filled with sufficient incompressibles to take the - 4 - j L 1 compressor offline and the system feedback is bypassed and line 2 pressure built to 150 psig, then it would take 11 seconds after the 3 flow reversal before the IPLH concentration would be reached in the 4 smallest room. 5 0 Flow indication in the sprinkler system sets off a fire 6 alarm to an attended location and automatically notifies the Fire 7 Department. Response to the alarms is immediate evacuation of the 8 building. 9 WHEREAS, in response to the City's concerns, Dillon has 10 recommended and the Owner has agreed to furnish the following 11 mitigation: 12 • Place emergency escape masks on every forklift truck, this 13 will assure that the mask and the user will remain in close proximity 14 to each other. 15 • Install notification appliances in every room on every 16 floor of the refrigerated space to provide audible and visual alarms to 17 the warehouseman upon detection of smoke or ammonia gas in the 18 building. 19 • Provide a corridor with a 1-hour fire resistive floor-to- 20 ceiling wall assembly from the stairs to the lobby. Openings into the 21 lobby shall be protected with self -closing or automatic closing 22 assemblies of at least 20 minute rating. 23 • Maintain exit signs and mark an area to assure that no 24 commodities are stored in such a way as to not block egress. 25 . Install a permanent rail to preclude the placement of 26 pallets within 4 feet of the door or its exit path; and 27 WHEREAS, Dillon points out that, under California Code of 28 Regulations, Title 24, Part 2, Chapter 34 division, Section 3401, - 5 - 1 existing buildings that were legal at the time of the Code, may have 2 their use continued provided such continued use is not dangerous to 3 life. 4 WHEREAS, given the extraordinary low occupant load of the 5 upper floors and basement of the Building, the lack of credible 6 _ignition, the difficulty of igniting and sustaining a fire in frozen 7 foods, the presence of a sprinkler system, the presence of an ammonia 8 detection system throughout the type of I-FR construction, the 9 familiarity of the occupants with the space, the vacuum operating 10 condition of the ammonia refrigeration system, the routing examination 11 and logging of the stair door condition, the emergency training and 12 apparatus provided for employees and the ability to communicate with 13 employees throughout the Building it is Dillon's opinion that the 14 Building is safe to occupy with a single egress and should not be 15 considered dangerous; and 16 WHEREAS, based upon the statements of fact and conclusions in 17 the Dillon report, the City agrees that if all of the mitigation 18 suggested in the report is implemented, the continued use of the 19 Building should not be considered dangerous; and 20 WHEREAS, under the alternative design provision of the 21 Uniform Building Code, the City's staff has recommended that the 22 Building be allowed to continue to be occupied with only one means of 23 egress from the upper floors and basement under the following 24 conditions: 2511 1. All existing safeguards mentioned in this report and in 26 the January 22, 2001 Dillon Consulting Engineers, Inc.'s letter shall 27 be maintained. 28 - 6 - 1 2' 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 right to inspect at all times to determine that all provisions outlined in the January 22, 2001 Dillon Consulting Engineers are being maintained. Failure to maintain any of the provisions may void, at the City's discretion this alternate design approval. WHEREAS, the City Council has considered testimony on behalf of the Owner of the Building at the appeal hearing, documentation offered on behalf of the Owner, staff reports supporting documentation submitted by the Director of Community Services and Water prior to the appeal hearing, and correspondence dated August 31, 2000 and October 11, 2000 from Samuel Kevin Wilson, Director of Community Services & Water, and correspondence dated September 27, 2000 and November 8, 2000 from Patrick A. Perry of Allen, Matkins, Leck, Gamble & Mallory LLP on behalf of the Owner and correspondence from Dillon dated January 22, 2001; and WHEREAS, the appeal hearing was closed during said meeting, and the matter was submitted to the City Council for decision; and WHEREAS, the evidence presented in this matter supports the following findings of fact: 1. The property in question consists, in part, of a building located at 4224 District Boulevard in the City of Vernon, Los Angeles County Assessor Parcel Number 6304-027-015, that contains a basement as well as six stories above the ground floor. 2. The Building located at 4224 District Boulevard in Vernon is currently owned by Vernon Cold Storage, LLC and Frank White is the President of Vernon Cold Storage, LLC. 3. By letter dated August 31, 2000-- (a) Mr. Wilson informed Vernon Properties that the City had determined that the Building was dangerous in accordance with the s 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 1997 Uniform Code for the Abatement of Dangerous Buildings and in violation of the 1997 Uniform Building Code due to the lack of sufficient exits and iced doors entering the existing exit stairwells. (b) Mr. Wilson ordered the immediate repair and maintenance of the doors entering the existing exit stairwells to comply with Section 1003.3.15 of the 1997 Uniform Building Code. (c) Mr. Wilson ordered the Owner to submit plans, receive City approval and commence construction of a second means of egress within 60 days to comply with the 1997 Uniform Building Code and further ordered that such construction be completed within 21 months. (d) Mr. Wilson advised that failure to comply with the order was grounds for termination of the occupancy permit and the building ordered vacated until the work was completed. (e) Mr. Wilson advised that if the City proceeded to cause the work to be done, the City would charge the costs thereof against the property or its Owner. WHEREAS, Section 104.2.8 of the 1997 Uniform Building Code allows for alternate designs when approved by the building official. Given the age of the building, type of construction and the safeguards currently in place and proposed to be employed and maintained, as outlined in the Dillon Consulting Engineers letter dated January 22, 2001, it is recommended that the alternate design be approved, that the one exit stair well be deemed acceptable and that the Building not be considered dangerous.

(SEAL) v BRUCE V. MALKENHORST, City Clerk - 13 - EXHIBIT AM" REVISED STAFF REPORT VERNON COLD STORAGE 4224 DISTRICT BOULEVARD BUILDING CODE VIOLATION FEBRUARY 15, 2001 On August 31, 2000 a letter was sent to Vernon Cold Storage. LLC, the owners of 4224 District Boulevard, requiring them to abate a dangerous condition. The subject building is six stories and is located on Los Angeles County Assessor Parcel Number 6304- 027-015. Section 302 of the 1997 Uniform Code for the Abatement of Dangerous Buildings considers a building dangerous if one of eighteen enumerated conditions exists provided that such conditions or defects exist to the extent that the life, health, property or safety of the public or its occupants are endangered. The building located at 4224 District Boulevard lacks sufficient number of exits_ Section 3401 of the 1997 Uniform Building Code states "Buildings in existence at the time of the adoption of this code may have their existing use or occupancy continued, if such use or occupancy was legal at the time of this code, provided such use is not dangerous to life. Appendix Chapter 34, Existing Structures outlines the minimum life safety requirements for existing buildings. Section 3407.1, Number of Means of Egress, states "Every floor above the first story used for human occupancy shall have at least two means of egress, one of which may be an exterior fire escape complying with Section 3407.4. Appendix lA of the 1997 Uniform Fire Code restates the exact same requirements for an existing building. Section 102 of the 1997 Uniform Building Code, Unsafe Buildings or Structures states, "All buildings or structures regulated by this code that are structurally unsafe or not provided with adequate egress or that constitute a fire hazard, or are otherwise dangerous to human life are, for the purpose of this section, unsafe." Section 102 goes on to state "All such unsafe buildings, structures or appendages are hereby declared to be a public nuisance and shall be abated by repair, rehabilitation, demolition or removal in accordance with procedures set forth in the Dangerous Building Code..." Section 302 of the 1997 Uniform Code for the Abatement of Dangerous Buildings considers the following conditions dangerous: 1) Whenever any door, aisle or passageway, stairway or other means of exit is so warped, worn, loose, torn or otherwise unsafe as to not provide safe and adequate means of exit in case of fire or panic. 2) Whenever, for any reason, the building or structure, or any portion thereof, is manifestly unsafe for the purpose for which it is being used. 3) Whenever any building or structure has been constructed, exists or is maintained in violation of any specific requirement or prohibition applicable to such building or structure provided by the building regulations of this jurisdiction, as specified in the building code or housing code, or any law or ordinance of this state or jurisdiction relating to the condition, location or structure of buildings. 4) Whenever any building or structure, because of obsolescence, dilapidated condition, deterioration, damage, inadequate exits, lack of sufficient fire - resistive construction, faulty electric wiring, gas connections or heating apparatus, or other cause is determined by the fire marshal to be a fire hazard. During recent city inspections of the subject building it was determined that the six story building contains only one exit stairwell and only one stairwell from the basement. It was determined that great force, far exceeding the Uniform Building Code requirement of 30 lbs. was necessary to open the doors into the stairwell due to icing. The City ordered the owner to immediately repair and maintain the doors entering the existing exit stairwells so that they comply with Section 1003.3.15, swing and opening force of the 1997 Uniform Building Code. Additionally, the City ordered the owner within 60 days to submit plans and receive city approval for the construction of a second means of egress for all floors and the basement in compliance with the 1997 Uniform Building Code. The exit may be an exterior fire escape complying with section 3407.4 of the Uniform Building Code. The construction of the second means of egress shall commence within 60 days and shall be completed within 21 months of the date of this notice. In addition to the fact that the building was constructed with only one exit stairwell, two other factors add to the concern of safety within the structure. Firstly, the building has an extensive piping network containing ammonia. The low ceiling heights increase the potential for a forklift rupturing 2 the piping system, thereby releasing ammonia within the structure. In certain quantities ammonia gas is both explosive and fatal. Secondly, the building was constructed with four elevator shafts. These vertical shafts provide a direct connection between floors and unlike modern buildings are not fully enclosed or protected with self -closing fire rated doors. Smoke from a fire can easily migrate from one floor to the next causing potential injuries or fatalities to occupants within the structure. It should be noted that existing buildings with automatic sprinklers are not required to have their vertical shafts retrofitted. These two safety concerns only added to the need for a second means of egress from the structure. . Lastly, it should be noted that the building code assigns an occupant load of 80 for each floor based on 40,000 square feet of refrigerated area. In a letter dated November 3,.2000 from Patrick Perry of Allen Matkins Leck Gamble & Mallory LLP, it is argued that Health and Safety Code Section 17922(f) provides that, "No local ordinance may permit any action or proceeding to abate violations or regulating governing maintenance of buildings, unless the building is a substandard building or the violation is a misdemeanor." Also, Section 17920.0(L) of the Health and Safety Code defines substandard building as "All buildings or portions thereof not provided with adequate exit facilities as required by this code, except those buildings or portions thereof whose exit facilities conform with all applicable laws at the time of their construction any which have been adequately maintained and increased in relation to any increase in occupant load, alteration or addition or change on occupancy." However, Section 17920.3(L) further provides that "When an unsafe condition exists through lack of, or improper location of, exits, additional exits may be required to be installed.' It should be noted that the sections quoted in the Patrick Perry letter is from State Housing Law and is not applicable to industrial buildings. In any case, the second part of Section 17920.3(L)-clearly allows for enforcement of constructing an adequate number of exits. Patrick Perry -also argues that since the State has not adopted the code for the abatement of dangerous buildings that it cannot be enforced by the City without making express findings. However, in Section 102, Unsafe Buildings or Structure, of the 1998 California Building Code it states in part, "All buildings or structures regulated by this code that are 3 structurally unsafe or not provided with adequate egress or that constitute a fire hazard or are otherwise dangerous to•human life are, for the purpose of this section, unsafe..." Section 102 further provides "All such unsafe building, structures or appendages are hereby declared to be a public nuisances and shall be abated by repair, rehabilitation, demolition or removal in accordance with the procedures set forth in the dangerous building code..." The building code specifically advises agencies to utilize the dangerous building code. Additionally, the City has adopted the Uniform Dangerous Building Code for its use. In addition pursuant to Sections 38660 and 50022.2 of the California Government Code the City may adopt by reference regulations for the abatement of unsafe buildings. The Patrick -Perry appeal letter completely ignores Section 3407.1 of appendix 34 existing structures, which require that every floor above the first story used for human occupancy shall have at least two means of egress. . Finally, Mr. Patrick Perry states that the estimated cost of adding the second exit would be approximately $726,000 and that this expense would result in a severe financial hardship severely affecting the financial viability of the building. In the City's opinion the mere fact that it will be expensive to add a second exit is no excuse for not providing a life safety requirement. Given Mr. Perry's opinion the City was prepared to deny Vernon Code Storage LLC's appeal. Given this knowledge, Vernon Cold Storage LLC engaged the services of Dillon Consulting Engineers, Inc. to perform an engineering study to determine if the building could be continued to be used safely. Attached herewith and incorporated herein is a letter dated January 22, 2001 from Dillon Consulting Engineers outlining that in Michael Dillon's professional opinion that the building can be safely occupied given -certain mitigation is provided. In brief, the following is Mr. Dillon's findings and conclusions: 1) The subject building is constructed in 1928 with fully sprinklered with a is 200x200 feet and the as four separate spaces square feet. Each floor a six -story freezer building 12-foot high ceilings and is dry pipe system. Each floor floors are divided into as many with the smallest being 3500 is served by one egress stair. 4 The effective travel distance from the most remote area to the stairs is 380 feet. 2) A second stairwell would be difficult to construct due to the building location on the property, the dock arrangement, the nature of the use of the building (cold storage) and the thickness of the walls, 46` inches. 3) From the 6th floor a person could safely exit the building in 4 minutes 18 seconds. The total elapse time from ignition to when a smoke layer from a fire involving the frozen commodity descends to a point 6 feet above the floor in the smallest storage room is 8 minutes 10 seconds. on an undivided floor, the same conditions are not reached until 72 minutes 36 seconds. 4) Second floors of any use with an occupant Toad of less than 10 are permitted to have only one exit, per Title 24, Part 2, Section 1004.2.3.2 and Table 1OA. An aviation control tower with an occupant load of 15 per floor and a maximum area of 1500 square feet is permitted to have only one exit even though it may be unlimited height when of type I-FR construction. The subject building can be classified as type I-FR and the actual occupant load due to the nature of the operations and environmental conditions is approximately l per floor. 5) Warehousemen are intimately familiar with the building geography and are equipped with and trained in the use of an emergency escape mask, which provides them up to 20 minutes of escape time through even poisonous gas clouds. 6) There is a written procedure whereby the stair doors in each level are inspected and logged daily to ensure they are not blocked or closed by ice or other obstructions. 7) All employees are trained to deal with an ammonia release as required by the Hazardous Materials Management Plan and the Risk Management Plan and Prevention Plan which is on file with the City. All warehousemen at this facility are provided with and trained in the use of a two-way transceiver. 8) The likelihood of a release is minimal because of the piping arrangement and the way the evaporators are suspended. The mounting is flexible which allows movement without damage. Any significant leak of ammonia will be detected by the ammonia detection system, which automatically cuts off the feed to the entire warehouse and transmits an alarm to an attended location. Additionally, the ammonia system operates at a below atmospheric pressure (vacuum) of approximately 6 inches. Under the unlikely scenario that if a 1/32 5 of an inch crack in the piping occurred and the leak went undetected, the piping system filled with sufficient incompressibles to take the compressor offiine and the system feedback is bypassed and line pressure built to 150 prig, then it would take 11 seconds after the flow reversal before the IPLH concentration would be reached in the smallest room., 9) Flow indication in the sprinkler system sets off a fire alarm to an attended location and automatically notifies the Fire Department. Response to the alarms is immediate evacuation of the building. Additionally, due to the City's concerns with the building having only one exit stairwell Mr. Dillon has recommended and the owner has agreed to furnish the following mitigation: a) Place emergency escape masks on every forklift truck, this will assure that the mask and the user will remain in close proximity to each other. b) Install notification appliances in every room on every floor of the refrigerated space to provide audible and visual alarms to the warehouseman upon detection of smoke or ammonia gas in the building. c) Provide a corridor with a 1-hour fire resistive floor -to -ceiling wall assembly from the stairs to the lobby. Openings into the lobby shall be protected with self -closing or automatic closing assemblies of at least 20 minute rating. d) Maintain exit signs and mark an area to assure that no commodities are stored in such a way as to not block egress. Additionally, a permanent rail will be installed to preclude the placement of pallets within 4 feet of the door or its exit path. Further, Mr. Dillon argues, under CCR, Title 24, Part 2, Chapter 34 division, Section 3401, existing buildings, which were legal at the time of the code, may have their use continued provided such continued use is not dangerous to life. Given the extraordinary low occupant load of the upper floors and basement of the building, the lack of credible ignition, the difficulty of igniting and sustaining a fire in frozen foods, the presence of a sprinkler system, the presence of an ammonia detection system throughout the type of I-FR construction, the familiarity of the occupants with the space, the vacuum operating condition of the ammonia refrigeration.system, the routing examination and logging of the stair door condition, the emergency training and apparatus provided for employees and the ability to communicate with employees throughout the building it is Mr..Dillon's opinion that 6 the building is safe to occupy with a single egress and should not be considered dangerous. The City is in agreement with this position. Therefore, under the alternative design provision of the Uniform Building Code it is recommended that the building be allowed to continue to be occupied with only one means of egress from the upper floors and basement under the following conditions: a) All existing safeguards mentioned in this report and in the January 22, 2001 Dillon Consulting Engineers, Inc.'s letter shall be maintained. b) The above mentioned mitigation shall be installed within six months of the date of City Council action and shall be maintained for the life of the building. c) The owner shall maintain insurance in the amount of $20,000,000.00 in a form and carrier approved by the City. The City shall be named as an additional insured. d) The type of use of the building shall not be changed. e) The owner shall execute a hold harmless agreement with the City in a form approved by the City Attorney. f) The building shall be available at all times for City inspection to determine continued compliance of all conditions. Failure to comply with any of these conditions may automatically void this approval. Lastly, the City shall have the ability to re-examine this issue in 5 years to confirm or deny the continued occupancy of the subject building. C:\My Documents\STAFF REPORTSWernon.ColdStorage.doc 7 STAFF REPORT VERNON COLD STORAGE 4224 DISTRICT BOULEVARD BUILDING CODE VIOLATION NOVEMBER 14, 2000 The City of Vernon has determined that the building located at 4224 District Boulevard is dangerous. The subject building is six stories and is located on Los Angeles County Assessor Parcel Number 6304-027-015. Section 302 of the 1997 Uniform Code for the -Abatement of Dangerous Buildings considers a building dangerous if one of eighteen enumerated conditions exists provided that such conditions or defects exist to the extent that the life, health, property or safety of the public.or its occupants are endangered. The building located at 4224 District Boulevard lacks sufficient number of exits. Section 3401 of the 1997 Uniform Building Code states "Buildings in existence at the time of the adoption of this code may have their existing use or occupancy continued, if such use or occupancy was legal at the time of this code, provided such use is not dangerous to life." Appendix Chapter 34, Existing Structures outlines the minimum life safety requirements for existing buildings. Section 3407.1, Number of Means•of Egress, states "Every floor above the first story used for human occupancy shall•have at least two means of egress, one of which may be an exterior fire escape complying with Section 3407.4. Appendix 1A of the 1997 Uniform Fire Code restates the exact same requirements for an existing building. Section 102 of the 1997 Uniform Building Code, Unsafe Buildings or Structures states, "All buildings or structures regulated by this code that are structurally unsafe or.not provided with adequate egress_or that constitute a fire hazard, or are otherwise dangerous to human life are, for the purpose of this section unsafe." Section 102 goes on to state "All such unsafe buildings, structures or appendages are hereby declared to be a public nuisance and shall be abated by repair, rehabilitation, demolition or removal in accordance with procedures set forth in the Dangerous Building Code..." Section 302 of the 1997 Uniform Code for the Abatement of Dangerous Buildings considers the following conditions dangerous: 1) Whenever any door, aisle or passageway, stairway or other means of exit is so warped, worn, loose, torn or otherwise unsafe as to not provide safe and adequate means of exit in case of fire or panic. 2) Whenever, for any reason,. the building or structure, or any portion thereof, is manifestly unsafe for the purpose for which it is being used. 3) Whenever any building or structure has been constructed, exists or is maintained in violation of any specific requirement or prohibition applicable to such building or structure provided by the building regulations of this jurisdiction, as specified in the building code or housing code, or any law or ordinance of this state or jurisdiction relating to the condition, location or structure of buildings. 4) Whenever any building or structure, because of obsolescence,.dilapidated condition, deterioration, damage, inadequate exits, lack of sufficient fire resistive construction, faulty electric wiring, gas connections or heating apparatus, or other cause is determined by the fire marshal to be a fire hazard. .During recent. city inspections of the subject building it was determined that the six story building contains only one exit stairwell and only one stairwell from•'the basement. It was determined that great force, far exceeding the Uniform Building Code requirement of 30 lbs. was necessary* to open the doors into the stairwell due to icing. The City ordered the owner to immediately repair and maintain the doors entering the existing exit stairwells so that they comply with Section 1003.3.15, swing and* opening force of the 1997 Uniform Building Code. Additionally, the City ordered the owner within 60 days to submit plans and receive city approval for the construction of a second means of egress for all floors and the basement in compliance with the 1997 Uniform Building Code. The exit may be an exterior fire escape complying with section 3407.4 of the Uniform Building Code. The construction of the second means of egress shall commence within 60 days and shall be completed within 21 months of the date of this notice. In addition to the fact that .the building was constructed with only one exit stairwell, two other factors add to the concern of safety within the structure Firstly, the building has an extensive piping network containing ammonia. The low ceiling heights increase the potential for a forklift rupturing the piping system, thereby releasing ammonia within the structure. In certain quantities ammonia gas is both explosive and fatal. Secondly, the building was constructed with four elevator shafts. These vertical shafts provide a direct connection between floors and unlike modern buildings are not fully enclosed or protected with -self -closing fire rated doors. Smoke from a fire can easily migrate from one floor to the next causing potential injuries ,or fatalities to occupants within the structure. It should be noted that existing buildings with automatic sprinklers are not required to have their vertical shafts retrofitted. These two safety concerns only add to the need for a second means of egress from the structure. In a letter dated November 3, 2000 from Patrick Perry of Alien Matkins Leck Gamble & Mallory LLP, it is argued that Health and Safety Code Section 17922(f) provides that, "No local ordinance may permit any action or proceeding to abate violations or regulating governing maintenance of buildings, unless the building is a substandard building or the violation is a misdemeanor." Also, Section 17920.0(L) of the Health and Safety Code defines substandard building as "All buildings or portions thereof not provided with adequate exit facilities as required by this code, except those buildings or portions thereof whose exit facilities conform with all applicable laws at the -time of their construction any which have been adequately maintained -and increased in relation to any increase in occupant load, alteration or addition or change on occupancy." However, Section 17920.3(L) further provides that "When an unsafe condition exists through lack of, or improper location of, exits, additional exits may be required to be installed. It should be noted that the sections quoted in the Patrick Perry letter is from State Housing Law and is not applicable to industrial buildings. In any case, the second part of Section 17920.3(L) clearly allows for enforcement of constructing an adequate number of exits. Patrick Perry also argues that since the State has not adopted the code for the abatement of dangerous buildings that it cannot be enforced by the City without making express findings. However, in Section 102, Unsafe Buildings or Structure, of the 1998 California Building Code it states in part, "All buildings or structures regulated by this code that are structurally unsafe or not provided with adequate egress or that constitute a fire hazard or are otherwise dangerous to human life are, for the purpose of this section, unsafe..." Section 102 I t , t �t t further provides "All such unsafe building, structures or appendages are hereby declared to be a public nuisances and shall be abated by repair, rehabilitation, demolition or removal in accordance with the procedures set forth in the dangerous building code..." The building code specifically advises agencies to utilize the dangerous building code. Additionally, the City -has adopted the Uniform Dangerous Building Code for its use. In addition pursuant to Sections 38660 and 50022.2 of the California Government Code the City may adopt by reference regulations for the abatement of unsafe buildings. The Patrick Perry appeal letter completely ignores Section 3407.1 of appendix 34 existing structures, which require that every floor above the first story used for human occupancy` shall have at least two means of egress. The City agrees that the building as currently utilized does not have.many employees within the structure, that the building is fully sprinklered and of non-combustible construction and that the building is used to store frozen products. However, we disagree that the product stored within the building is non- combustible. Frozen foods will burn given an ignition source. Lastly, Patrick Perry states that the estimated cost of adding the second exit would be approximately $726,000 and that this expense would result in a severefinancial hardship severely affecting the financial viability of the building. The mere fact that it will be expensive to add a second exit is no excuse for not providing a life safety requirement. Therefore,.it is recommended that a second exit be required to be constructed.

Very truly yours, Bruce Vr Malkenhorst City Administrator/City Clerk BVM/ng February 15, 2001 TO: Bruce V. Malkenhorst, City Administrator FROM: Samuel "Kevin" Wilson, Director of Community Services & Water SUBJECT: APPEAL OF BUILDING CODE VIOLATION - 4224 DISTRICT BLVD. The City of Vernon issued a notice to Vernon Cold Storage LLC, that the building located at 4224 District Boulevard, Vernon, California was dangerous. It was determined that the building lacked a sufficient number of exits. Appendix Chapter 34 of the 1997 Uniform Building Code and the 1998 California Building Code Appendix Chapter 34 establishes the life safety requirements for existing buildings. Section.3407.1 states, "Every floor above the first story used for human occupancy shall have'at least two means of egress, one of which may be a fire escape. The six story building located at 4224 District was constructed with only one stairwell. The owner of the building was ordered to have a second egress constructed within the building. Patrick A. Perry, of the law firm of Allen Matkins Leck Gamble & Mallory LLP, on behalf of the building owner, Vernon Cold Storage LLC, has appealed my determination and, therefore a hearing was set to consider the appeal of November 21, 2000. Attached herewith is: 1) City of Vernon's letter dated August 31, 2000 determining that the building located at 4224 District Boulevard is dangerous and ordering the construction of two second means of egress. 2) Allen Matkins Leck Gamble & Mallory LLP's appeal letter dated September 27-, 2000. 3) City of Vernon's letter to Vernon Cold Storage dated October 11, 2000, setting the hearing date and time. 4), Allen Matkins Leck Gamble & Mallory LLP's letter dated November 8, 2000 setting forth their reason for appeal. 5) Dillon Consulting Engineers, Inc.'s letter dated January 22, 2001. 6) Revised City Staff Report. The owner of the building has agreed to provide, in addition to the existing safeguards in place at the subject building, a one hour fire resistive exit corridor from the stairs to the lobby, provide an emergency escape mask on every forklift truck in addition to the masks currently being provided in each room and placement of notification on appliances in every room on every floor to provide audible and visual alarms to the occupants when smoke or ammonia are detected. The owner will also mark and place railings in areas around the exit doors to exclude storage in order to insure that the doors are accessible at all times. Lastly the property owner will provide and maintain insurance in the amount of $20,000,000.00 for the life of the building and name the City as an additional insured. Section 104.2.8 of the 1997 Uniform Building Code allows for alternate designs when approved by the building official. Given the age of the building, type of construction and the safeguards currently in place and proposed to be employed and maintained, as outlined in the Dillon Consulting Engineers letter dated January 22, 2001, it is recommended that the alternate design be approved, that the one exit stair well be deemed acceptable and that the building not be considered dangerous. The owner of the building shall commence the above mentioned improvements immediately and all safeguards and insurance shall be in place within six months. Additionally, the owner shall execute a hold harmless agreement with the`City in a form approved;by the City Attorney and the cold storage use of the building shall not be changed. This course of action shall be construed as a temporary approval and this matter may be revisited by the City in five years to ensure that the safeguards are sufficient. The City shall have the right to inspect at all times to determine that all provisions outlined in the January 22, 2001 Dillon Consulting Engineers are being maintained. Failure to maintain any of the provisions may void, at the City's discretion this alternate design approval. SKW/ca Enclosure c: City Attorney S ' .w CITY COUNCIL LEONIS C. MALBURG Mayor THOMAS A.

Director of Community Services and Water City of Vernon 4305 Santa Fe Avenue Vernon, California 90058 Re: Appeal of Vernon Cold Storage, LLC Before the Board of Appeal for the City of Vernon Dear Mr. Wilson: ReceI V=0 SEP2810� This firm represents Vernon Cold Storage, LLC (the "Owner"), owner of the building located at 4224 District Boulevard (the 'Building") in the City of Vernon (the "City"). We are in receipt of your letter to the Owner, dated August 31, 2000, in which you require the Owner to provide two means of egress from every floor above the first story and from the basement of the Building pursuant to certain requirements set forth in the 1997 Uniform Building Code. On behalf of the Owner, we hereby appeal this determination on the grounds that compliance with these requirements would impose an undue hardship on the Owner. The Building was constructed in 1924, and contains a basement as well as five stories above the ground floor. Each floor consists of approximately 40,000 square feet of floor area. The Building is constructed of poured in place concrete and conformed to all applicable building code requirements at the time it was constructed. The Building is fully sprinklered and is used as a cold storage warehouse. The Building has operated in its current form for 76 years. During that time there has never been any incident that constituted a threat to the health or safety of the Building occupants. Nor in all that time has the City ever found it necessary to initiate any enforcement action against the Building for noncompliance with applicable building code requirements. The existence of only one means of egress from each floor does not pose a significant risk to the health or safety of the Building occupants because the public is strictly prohibited from entering any of the upper floors, and there is never more than one employee on any upper floor at any time. There are approximately eight employees who work at the loading dock on the Los Angeles Oranec Countv Allen Matkins Leck Gamble & Mallory LLP attormys'at taw Mr. Samuel Kevin Wilson, P.E. September 27, 2000 Page 2 ground floor and three employees who work in the Building office, also located on the ground floor. The safety of the employees who work in the Building is of paramount importance to the Owner. However, because of the small number of occupants, the nature of the use, the solid concrete construction, and the existing fire sprinkler system, the Building constitutes a minimal threat to life safety in the event of a fire or other catastrophe. On the other. hand, compliance with the requirement to provide two means of egress from every story except the ground floor would be prohibitively expensive. The Owner has obtained a bid of $726,000 for.the construction of an exterior fire escape for the Building. The extremely high cost is due to the fact that because of the use of the Building as a cold storage warehouse, the solid concrete exterior walls of the Building are approximately 4.5 feet thick. To create openings in these walls for the construction of a fire escape is therefore extremely difficult as well as costly, thus imposing an undue burden on the Owner out of all proportion to the level of risk involved.. . Because of the extremely low risk posed by the existing configuration of the Building to the health and safety of the Building occupants and the extremely high cost to the Owner to fully comply with the requirements set forth in your letter of August 31, 2000, we therefore respectfully request that you set aside your determination that the Owner provide two means of egress from each floor or work to find a less onerous means for the Owner to continue its operations in. the Building without incurring severe hardship and expense. After you have had a chance to review this letter, we. would appreciate an opportunity to meet with you to discuss mutually acceptable solutions to address the issues raised in your determination. In the meantime, please call with any questions or if I can provide any additional information with respect to this matter. Very truly yours, PAP:kt Patrick A. Perry cc: Mr. Frank White Peter J.

Director of Community Services and Water City of Vernon 4305 Santa Fe Avenue Vernon, California 90058 Re: 4224 District Boulevard, Vernon, California Dear Mr. Wilson: RECEIVED Community Services We are in receipt of your letter of October 11, 2000, in which you have requested additional information with respect to the appeal by Vernon Cold Storage, LLC (the "Owner"), owner of the building located at the above -referenced address (the "Building"), of your determination that the Building is required to have two exits from each floor above the first story. As we stated in our letter of September 27, 2000, the Owner's appeal of your determination is based on the grounds that the Building was constructed in 1924, of poured in place concrete and conformed to all applicable building code requirements at the time it was constructed. Section 17922(f) of the California Health and Safety Code provides that "No local ordinance may permit any action or proceeding to abate violations of regulations governing maintenance of existing buildings, unless the building is a substandard building or the violation is a misdemeanor." Section 17920.3(1) of the California Health and Safety Code defines substandard buildings as "All buildings or portions thereof not provided with adequate exit facilities as required by this code, except those buildings or portions thereof whose exit facilities conformed with all applicable laws at the time of their construction and which have been adequately maintained and increased in relation to any increase in occupant load, alteration or addition, or any change in occupancy." Your determination relies on the definition of dangerous buildings contained in the Uniform Code for the Abatement of Dangerous Buildings. However, the Uniform Code for the Abatement of Dangerous Buildings has not been adopted by the State of California for inclusion in the State Building Standards Code. (see, Health and Safety Code § 17922). It is well settled that the State Building Standards Code preempts local building regulations except to the extent that a local jurisdiction makes express findings that modifications to the requirements of the State Building Standards Code are reasonably necessary because of local climatic, geological, or Los Angeles Orange County San Diego San Francisco West Los Angeles V t _ Allen Matkins Leck Gamble & Mallory LLP afforneys at law Mr. Samuel K. Wilson, P.E. November 8, 2000 Page 2 topographical conditions. (see, Health and Safety Code § 17958; Briseno v. City of Santa Ana, 6 Cal.App.4'' 1378 (1992)). Absent such express findings in connection with the City's adoption of the Uniform Code for the Abatement of Dangerous Buildings, the City cannot enforce the definition of dangerous buildings contained therein against the Building. Section 17920.3(l) of the Health and Safety Code further provides that "When an unsafe condition exists through lack of, or improper location of, exits, additional exits may be required to be installed." However, due to the nature of the construction and use of the Building, -the existence of only one means of egress from each floor of the Building above the first story does not constitute an unsafe condition. As you can see from the drawings attached hereto as Exhibit A, the Building is constructed entirely of poured in place concrete. The exterior walls consist of double concrete wall construction varying in thickness from 12" to 16", with a 12" space in between. Ile concrete floor slabs are 9-1/2" thick. Except for a small office and loading dock on the first floor, the entire Building is used -as a refrigerated warehouse for the storage of frozen meat, fish, and produce. A list of the products stored in the Building is attached hereto as Exhibit B. The Building is fully sprinklered, and no combustible materials are stored inside the Building. There are approximately eight employees who work at the loading dock on the ground floor of the Building and four employees who work in the Building office, also located on the ground floor. In addition, there are seven warehousemen assigned to the Building, each of whom is assigned to one floor. As a result, there is never more than one employee on any upper floor at any time. Moreover, members of the general public are strictly prohibited from entering any of the upper floors. Accordingly, there is only a minimal risk that anyone could be injured under existing circumstances in the event of a fire or other catastrophe because the only people present on the upper floors are employees who are fully aware of any risks associated with their occupancy of the Building and who are thoroughly familiar with the existing configuration of the Building exits. The Building has operated in its current form for approximately 76 years. During that time there has never been any incident that constituted a threat to the health or safety of the Building occupants. Nor in all that time has the City ever found it necessary to initiate any enforcement action against the Building for noncompliance with applicable building code requirements. Even if the Building were to be considered unsafe, Section 104.2.7 of the State Building Standards Code allows building officials to grant modifications to the provisions of the Code where practical difficulties prevent strict adherence to Code provisions. Given the nature of the construction of the Building, construction of an additional means of egress from the upper floors definitely constitutes such a practical difficulty. As shown in the photographs attached as Allen Matkins Leck Gamble & Mallory LLP attorneys at law Mr. Samuel K. Wilson, P.E. November 8, 2000 Page 3 Exhibit C, the Building has no openings in the exterior walls above the first floor. Access to a fire escape would require cutting new openings in the double exterior concrete walls of the Building, at an estimatedcost of $726,000. This expense would result in a severe financial burden that would seriously affect the financial viability of Building operations. The protection of Building occupants is of the utmost importance to the Owner. If the configuration of the Building posed a serious threat to the health and safety of the Building occupants, the Owner would be the fast to initiate all necessary measures to remedy any unsafe conditions. However, given that the Building complied with all applicable building code requirements at the time it was constructed, that it is constructed entirely of poured in place concrete, is fully sprinklered, is not open to the public, and does not allow for the storage of combustible materials, we feel that a modification to current building code requirements is justified to permit Building operations to continue under present conditions. Under the circumstances, we feel that strict compliance with the current egress requirements of the State Building Standards Code is neither mandated nor warranted. Nevertheless, we would welcome an opportunity to discuss the matter further and appreciate your offer to meet with us to discuss these issues once you have had an opportunity to review these materials. In the meantime, please call with any questions or if I can provide any additional information with respect to this matter. PAP:kt Enclosures cc: Eduardo Olivo, Esq.

Director RECEIVED VAN 2 4 2001 Community Services Department of Community Services & Water City of Vernon 4305 Santa Fe Ave Vernon, CA 90058 RE: Federal Cold Storage, dba Pacific Cold Storage, a division of P & O Cold Logistics 4224 District Boulevard Vernon, CA 90058-3108 SUB: Request for Modification under CCR Title 24, Part 2, Section 104.2.7 Dear Mr. Wilson, ?01LLon CONSULTING ENGINEERS INCORPORATED As a result of the meeting in your office and our recent telephone conversation, I am submitting this revised formal Request for Modification with regard to the egress arrangement for the storage floors at the above referenced building. DESCRIPTION OF BUILDING The referenced building is a six -story freezer warehouse, within which are stored frozen foods. The ceiling height on each floor is approximately 12 feet. The facility is fully sprinklered, using a dry pipe system due to the below freezing conditions. The facility was built in 1928. The overall exterior dimensions of the building in plan are 200 feet by 200 feet. The floors are divided into as many as four separate spaces, with the smallest being about 3500 square feet. DESCRIPTION OF PROBLEM As constructed in 1928, the facility was equipped with a single egress stair serving floors 2 through 6, located in the northeast corner of the building. On each floor, this stair incorporates a 2'0" x 6'0" insulated door as the means of entry to the stair. These doors swing opposite to the direction of egress, which is allowed under Title 24, Part 2, Section 1003.3.1 for occupant loads of less than 10, as is the case here. The stair itself has a tread. width of 3'6" and an effective egress width of 35". The stair has an 8" riser height and a 1165 East San Antonio Drive • Suite D-1 • Long Beach, California 90807 0 Tel (562) 422-2205 * Fax (562) 422-0054 Samuel Kevin Wilson, P.E. 22 January 2001 Page 2 of 7. 9-1/2" tread depth. The stair enclosure is equipped with lighting fixtures served from the main power, having battery backup for emergencies. Internally illuminated exit signs identifying the location of the exit doors are placed above the doorways so as to be seen from within the storage room. The storage rooms are also provided with emergency illumination in the form of fixtures with battery backup. The code -measured travel distance on the storage floors is approximately 283 feet; however, the actual effective travel distance from the most remote location on any floor is approximately 380 feet. At the base of the stair, the occupant must leave the stair enclosure, enter the office area, then travel another 20 feet to the exterior. The office area is also sprinklered with a wet system and is completely separated from the refrigerated warehouse. There is a practical difficulty involved in establishing a second stair enclosure within the building to serve the upper floors. Such an enclosure must be constructed of masonry or concrete if it is to be of the required fire resistive time period since drywall construction cannot sufficiently exclude the penetration of water vapor into the wall assembly under the extreme vapor pressure differences encountered in this type of facility. Water vapor intrusion will necessarily result in ice build-up within, under, above and around the wall assembly, eventually rupturing its attachments and causing its failure. The environmental conditions under which a reinforced concrete or masonry stair and enclosure would have to be constructed are incompatible with pouring concrete or laying up masonry. It is completely infeasible to vacate and warm the building for construction purposes and then chill it down again for service. Even if temporary insulated walls were erected to enclose the work area and allow only the enclosed space to be warmed up to an acceptable temperature for concrete and or masonry work, there still remains the logistical difficulty of getting concrete or mortar into the space without first having to pass through the freezers. Moving workers and less temperature sensitive materials presents other practical difficulties in that these too must traverse the subfreezing portions of the building in order to enter the work area and thus reduce the temperature within the temporary work enclosure to below freezing again requiring a period of time to reheat the work space. It would also be difficult to locate such a second stair inside the building, as the enclosure would either terminate on the loading dock or entail construction of an extension of the enclosure to the exterior, significantly impeding normal operations (see attached sketch.) There are also practical difficulties involved in establishing a second exit on the exterior of the building (either a fire escape or a stair.) There are limited locations where such an exterior exit could be placed without terminating on the loading dock and creating a similar problem as discussed above or requiring the occupants to exit across the processing area roof prior to descending to grade and then exiting to the public way across the railroad easement. In fact, the only other place to put such an exterior exit is directly on District Boulevard, which would create a security problem for the building. More importantly, the exterior wall actually consists of two concrete walls spaced o �11 k a1LLon Samuel Kevin Wilson, P.E. 22 January 2001 Page 3 of 7 foot apart, giving a total wall thickness of 46". There are no freezer doors made in this configuration and it presents extraordinary practical difficulties to rework a large enough portion of the exterior wall in order to accept the more commonly manufactured freezer doors intended for exterior applications. REQUEST FOR MODIFICATION The requested modification due to practical difficulties is to permit the existing exiting condition, which has served the building adequately for 72 years, to continue in use as is, subject to the conditions described below. TECHNICAL ANALYSIS AND JUSTIFICATION This proposed modification, for this individual case, does not in any way affect the degree of structural integrity nor does it lessen any fire protection already afforded the building. The issue then becomes whether the intent and purpose of the code is still maintained. The purpose and intent applicable in this instance is that of life safety of the occupants. Because of the nature and arrangement of the storage, there is only one warehouseman on each of floors 2 through 6. An analysis of the exiting time required for these 5 individuals to walk from the most remote location on a floor to the stair, pass through the door, and then descend to the first floor; leave the stair enclosure, and traverse the office to the exterior of the building is as follows: It takes 2 minutes 54 seconds* from the 2nd floor It takes 3 minutes 18 seconds* from the 3`d floor It takes 3 minutes 36 seconds* from the 4d' floor It takes 4 minutes 00 seconds* from the 5t' floor It takes 4 minutes 18 seconds* from the a floor *all times are approximate based on the calculations performed using NIST's FPETOOL NIST is the National Institute of Standards and Technology, a division of the United States Department of Commerce. It was formerly known as NBS or the National Bureau of Standards and its main research campus is in Gaithersburg, Maryland. FPETOOL, ASET-B and a number of other fire, life safety, and building related programs have been developed by NIST over the years and, after extensive internal review and testing and extensive external peer review and testing, these programs are made available in the public domain. Copies of these and more along with the support documentation are available for free at htty://www.nist.gov or from their ftp site. -446L .,l orlLon Samuel Kevin Wilson, P.E. 22 January 2001 Page 4 of 7 Total elapsed time from ignition to when a smoke layer from a fire involving the frozen commodity descends to a point 6 feet above the finished floor surface in the smallest storage room is 8 minutes 10 seconds*. On an undivided floor, the same conditions are not reached until 72 minutes 36 seconds* after ignition. 6 feet above the finished floor was used in the analysis because it corresponds with the height of the top of the doors into the stair tower. Any smoke that descends below this level poses the risk of contaminating the exit path within the stair. Furthermore, NFPA 92B uses 6 feet as the height above the floor for determining viable exiting conditions under smoke control mode. * all times are approximate based on the calculations performed using NIST's ASET-B Assuming that a delay in discovery and recognition of need to evacuate for an individual in a non -fire space is 4 minutes, then the stair itself remains safe since the smoke layer has yet to descend below 9 feet 6 inches above finished floor in even the smallest space, and the stair door head is 6 feet above finished floor. The time to traverse a floor from the most remote point and enter the stair, including a one minute effort to pass through the stair door, is only 2 minutes 31 seconds. So even if the worker is as far away from the stair as possible and the fire is in the space adjacent to the stair, there is sufficient time for the worker to safely exit the floor and enter the stair enclosure before the smoke layer descends to the top of the door. With respect solely to the number of exits on the upper floors, the code's basic premise is that two exits are to be provided; however, there are exceptions to this that take into account the number of occupants and the nature of the use of the space. For example, second floors of any use with an occupant load of less than 10 are permitted to have only one exit, Title 24, Part 2, Section 1004.2.3.2 and Table 10-A. Even an aviation control tower with an occupant load of 15 per floor is permitted to have only one exit even though it may be of unlimited height when of Type I-FR construction. As this building can be legitimately classified as Type I-FR and as the actual occupant load, due to the nature of the operations and the environmental conditions therein, does not exceed 1 per floor on the upper floors (5 persons total for floors 2 through 6), it would not be inappropriate to apply the express intent of the code for these unique situations to this particular case. The exiting condition from the stair requiring personnel to leave the stair and pass through the office space does present a reasonably foreseeable problem in that the office space represents the more probable ignition and fire scenario for the building than do the refrigerated storage spaces above. Insofar as this is the only exit path for the personnel using the stair, fire protection for this area assumes a special importance. Since this office area is fully sprinklered and very small, it is reasonable to accomplish this protection by the construction of a 1-hour fire resistive floor -to -ceiling wall assembly to create a Samuel Kevin Wilson, P.E. 22 January 2001 Page 5 of 7 corridor from the stair to the lobby. Openings into the lobby should be protected with self -closing or automatic -closing assemblies of at least 20 minute rating. Another basic premise of the code is that existing buildings which were legal at the time of adoption of the code may have their use continued provided such continued use is not dangerous to life, cf. CCR, Title 24, Part 2, Chapter 34, Division I, Section 3401. In this case, while continued use may present some minor risk (the possibility of harm), it does not rise to the level of dangerous (the likelihood of harm.) It is also worth noting that the individual warehouseman on a particular floor is necessarily intimately familiar with the building geography. This is his daily place of work. He is also equipped with and trained in the use of an emergency escape mask, which provides him up to 20 minutes of escape time through even poisonous gas clouds, let alone the few minutes of travel below a smoke layer he would have to endure. The placement of such emergency escape masks will be revised so that there will now be a mask on every fork truck on every floor. This assures that the mask and the user will remain in close proximity to each other. Arrangements are proceeding to install notification appliances in every room on every floor of the refrigerated spaces to provide audible and visual alarms to the warehousemen. Additionally, each warehouseman will continue to be equipped with a two-way radio transceiver, the use of which is a normal and ordinary part of his routine. There is a written evacuation notification and implementation procedure in the event of either a fire or an ammonia leak. Finally, there is a written procedure whereby the stair doors on each level are inspected and logged daily to ensure that they are not blocked open or closed by ice or other obstructions. The possibility of installing electric heating devices to automatically accomplishing jamb de-icing at each of these doors was investigated. It is my professional engineering opinion and the opinion of the warehouse operator that such electric heating presents an unacceptable risk of fire due to the presence of cork and pitch insulation in the doors and walls, and that proper adherence to the written procedure will accomplish the intended level of personnel safety. With respect to the potential of harm from an ammonia leak within the facility, not only are all the employees trained to deal with an ammonia release as required by the Hazardous Materials Management Plan (HMMP) and the Risk Management and Prevention Plan (RMPP), of which it is a part and was prepared in 1994 and is on file with the City of Vernon Fire Department, but the likelihood of such a release on any of the floors is minimal because of the way the piping is arranged and the evaporators are suspended. The mounting is flexible which allows for movement without damage during seismic, thermal, and mechanical displacements. Mechanical displacements by material handling vehicles or the like would almost certainly have to be intentional. Even then, ?�k DiLLon Samuel Kevin Wilson, P.E. 22 January 2001 Page 6 of 7 most likely result would be a half circumferential crack at a joint. Since the piping is 2" nominal diameter and such a crack would be approximately 1/32nd of an inch in width. That would correspond to an air leakage rate of 16.08 standard cubic feet per minute (scfin) into the pipe since the system is operating at below atmospheric pressure (vacuum) of approximately 6 in. Hg. Assuming the unlikely scenario where the leak went unnoticed until the piping system filled with sufficient incompressibles to take the compressor off line and the system feedback somehow bypasses the system check valves and other safeties and thus raises the line pressure up to 150 psig, then the leakage of ammonia into the space would be approximately 114 scfin of NH3. Using the volume of the smallest room, this would indicate that there is 11 seconds after this flow reversal before the IDLH concentration could be reached in that room. Even this concentration is not that serious to individuals who have worked around ammonia, have access to a safety mask, and are trained for such emergencies. For the larger spaces, this time becomes an even more acceptable 32 seconds, again after flow reversal. It must be pointed out that these acceptable access -to -mask times or escape times are computed only after an improbable event has taken considerable time to precipitate a near impossible event by changing the pressure conditions within the entire system from that of a vacuum to that of the high pressure receiver. Furthermore, these times only involve the room in which this extraordinarily improbable event occurs. Any significant leak of ammonia will be detected by the ammonia detection system which automatically cuts off the feed to the entire warehouse, transmits an alarm to an attended location and results in both the radio and intercom contact of all warehousemen ordering an immediate evacuation. Similarly, flow indication at the sprinkler system transmits a fire alarm to an attended location and the Vernon Fire Department and results in the same immediate evacuation response. All warehousemen at this facility are provided with and trained in the use of two-way radio transceivers, which are a necessary part of their ordinary work functions. At the stair doors, there are exit signs and the area will be appropriately marked to assure that no commodities are stored in such a way as to block egress. Additional measures are being taken to further assure that commodities cannot be placed in front of the doors. These measures consist of the installation of a permanent rail to preclude the placement of pallets within 4 feet of the door or its exit path. As a part of the daily logging of the stair door condition to assure its continued usefulness as an exit, an examination of the immediate vicinity for compliance with maintaining the egress path and the logging of the conditions observed will be incorporated. Attached to this letter are some of the relevant documents from P&O concerning notification procedures, logging protocols, ammonia leaks, and emergency exiting. In summary, the extraordinarily low occupant load on not only any but all of the upper floors, the lack of a credible ignition scenario, the difficulty of igniting ' and sustaining 0k c�iLLon ` Samuel Kevin Wilson, P.E. 22 January 2001 Page 7 of 7 fire in frozen foods, the presence of sprinkler systems, the presence of an ammonia detection system throughout, the Type I-FR construction, the familiarity of the occupants with the space they in which they routinely carry out there daily duties and tasks, the operating conditions of the ammonia refrigeration system, the routine examination and logging of stair door condition, the emergency training and apparatus provided the employees, and the ability to communicate with them all speak strongly in favor of the continued use of this building as it is currently configured as a safe and reasonable alternative to the practical difficulties involved in retroactively carrying out the provisions of the present day code. In conclusion, it is my professional engineering opinion that, subject to the conditions described above, the continued use of the freezer storage building with a single egress stair provides reasonable safety to the occupants Very truly urs, -8 i ael ar illon, .E., C.Eng. �i. �oNgN►c�:?f -OF CAO attachments: (previously submitted) cc: Robert W.

The subject building is six stories and is located on Los Angeles County Assessor Parcel Number 6304- 027-015. Section 302 of the 1997 Uniform Code for the Abatement of Dangerous Buildings considers a building dangerous if one of eighteen enumerated conditions exists provided that such conditions or defects exist to the extent that the life, health, property or safety of the public or its occupants are endangered. The building located at 4224 District Boulevard lacks sufficient number of exits. Section 3401 of the 1997 Uniform Building Code states "Buildings in existence at the time of the adoption of this code may have their existing use or occupancy continued, if such use or occupancy was legal at the time of this code, provided such use is not dangerous to life." Appendix Chapter 34, Existing Structures outlines the minimum life safety requirements for existing buildings. Section 3407.1, Number of Means of Egress, states "Every floor above the first story used for human occupancy shall have at least two means of egress, one of which may be an exterior fire escape complying with Section 3407.4. Appendix lA of the 1997 Uniform Fire Code restates the exact same requirements for an existing building. Section 102 of the 1997 Uniform Building Code, Unsafe Buildings or Structures states, "All buildings or structures regulated by this code that are structurally unsafe or not provided with adequate egress or that constitute a fire hazard, or are otherwise dangerous to human life are, for the purpose of this section, unsafe." Section 102 goes on to state "All such unsafe buildings, structures or appendages are hereby declared to be a public nuisance and shall be abated by repair, rehabilitation, demolition or removal in accordance with procedures set forth in the Dangerous Building Code..." Section 302 of the 1997 Uniform Code for the Abatement of Dangerous Buildings considers the following conditions dangerous: 1) Whenever any door, aisle or passageway, stairway or other means of exit is so warped, worn, loose, torn or otherwise unsafe as to not provide safe and adequate means of exit in case of fire or panic. 2) Whenever, for any reason the building or structure, or any portion thereof, is manifestly unsafe for the purpose for which it is being used. 3) Whenever any building or structure has been constructed, exists or is maintained in violation of any specific requirement or prohibition applicable to such building or structure provided by the building regulations of this jurisdiction, as specified in the building code or housing code, or any law or ordinance of this state or jurisdiction relating to the condition, location or structure of buildings. 4) Whenever any building or structure, because of obsolescence, dilapidated condition, deterioration, damage, inadequate exits, lack of sufficient fire - resistive construction, faulty electric wiring, gas connections or heating apparatus, or other cause is determined by the fire marshal to be a fire hazard. During recent city inspections of the subject building it was determined that the six story building contains only one exit stairwell and only one stairwell from the basement. It was determined that great force, far.exceeding the Uniform Building Code requirement of 30 lbs. was necessary to open the doors into the stairwell due to icing. The City ordered the owner to immediately repair and maintain the doors entering the existing exit stairwells so that they comply with Section 1003.3.15, swing and opening force of the 1997 Uniform Building Code. Additionally, the City ordered the owner within 60 days to submit plans and receive city approval for the construction of a second means of egress for all floors and the basement in compliance with the 1997 Uniform Building Code. The exit may be an exterior fire escape complying with section 3407.4 of the Uniform Building Code. The construction of the second means of egress shall commence within 60 days and shall be completed within 21 months of the date of this notice. In addition to the fact that the building was constructed with only one exit stairwell, two other factors add to the concern of safety within the structure. Firstly, the building has an extensive piping network containing ammonia. The low ceiling heights increase the potential for a forklift rupturing 2 the piping system, thereby releasing ammonia within the structure. In certain quantities ammonia gas is both explosive and fatal. Secondly, the building was constructed with four elevator shafts. These vertical shafts provide a direct connection between floors and unlike modern buildings are not fully enclosed or protected with self -closing fire rated doors. Smoke from a fire can easily migrate from one floor to the next causing potential injuries or fatalities to occupants within the structure. It should be noted that existing buildings with automatic sprinklers are not required to have their vertical shafts retrofitted. These two safety concerns only added to the need for a second means of egress from the structure. Lastly, it should be noted that the building code assigns an occupant load of 80 for each floor based on 40,000 square feet of refrigerated area. In a letter dated November 3, 2000 from Patrick Perry of Allen Matkins Leck Gamble & Mallory LLP, it is argued that Health and Safety Code Section 17922(f) provides that, "No local ordinance may permit any action or proceeding to abate violations or regulating governing maintenance of buildings, unless the building is a substandard building or the violation is a misdemeanor. Also, Section 17920.0(L) of the Health and Safety Code defines substandard building as "All buildings or portions thereof not provided with adequate exit facilities as required by this code, except those buildings or portions thereof whose exit facilities conform with all applicable laws at the time of their construction any which have been adequately maintained and increased in relation to any increase in occupant load, alteration or addition or change on occupancy." However, Section 17920.3(L) further provides that "When anunsafecondition exists through lack of, or improper location of, exits, additional exits may be required to be installed. It should be noted that the sections quoted in the Patrick Perry letter is from State Housing Law and is not applicable to industrial buildings. In any case, the second part of Section 17920.3(L) clearly allows for enforcement of constructing an adequate number of exits. Patrick Perry also argues that since the State has not adopted the code for the abatement of dangerous buildings that it cannot be enforced by the City without making express findings. However, in Section 102, Unsafe Buildings or Structure, of the 1998 California Building Code it states in part, "All buildings or structures regulated by this code that are 3 structurally unsafe or not provided with adequate egress or that constitute a fire hazard or are otherwise dangerous to human life are, for the purpose of this section, unsafe..." Section 102 further provides "All such unsafe building, structures or appendages are hereby declared to be a public nuisances and shall be abated by repair, rehabilitation, demolition or removal in accordance with the procedures set forth in the dangerous building code..." The building code specifically advises agencies to utilize the dangerous building code. Additionally, the City has adopted the Uniform Dangerous Building Code for its use. In addition pursuant to Sections 38660 and 50022.2 of the California Government Code the City may adopt by reference regulations for the abatement of unsafe buildings. The Patrick Perry appeal letter completely ignores Section 3407.1 of appendix 34 existing structures, which require that every floor above the first story used for human occupancy shall have at least two means of egress. Finally, Mr. Patrick Perry states that the estimated cost of adding the second exit would be approximately $726,000 and that this expense would result in a severe financial hardship severely affecting the financial viability of the building. In the City's opinion the mere fact that it will be expensive to add a second exit is no excuse for not providing a life safety requirement. Given Mr. Perry's opinion the City was prepared to deny Vernon Code Storage LLC's appeal. Given this knowledge, Vernon Cold Storage LLC engaged the services of Dillon Consulting Engineers, Inc. to perform an engineering study to determine if the building could be continued to be used safely. Attached herewith and incorporated herein is a letter dated January 22, 2001 from Dillon Consulting Engineers outlining that in Michael Dillon's professional opinion that the building can be safely occupied given certain mitigation is provided. In brief, the following is Mr. Dillon's findings and conclusions: 1) The subject building is constructed in 1928 with fully sprinklered with a is 200x200 feet and the as four separate spaces square feet. Each floor a six -story freezer building 12-foot high ceilings and is dry pipe system. Each floor floors are divided into as many with the smallest being 3500 is served by one egress stair. 4 The effective travel distance from the most remote area to the stairs is 380 feet. 2) A second stairwell would be difficult to construct due to the building location on the property, the dock arrangement, the nature of the use of the building (cold storage) and the thickness of the walls, 46 inches. 3) From the 6th floor a person could safely exit the building in 4 minutes 18 seconds. The total elapse time from ignition to when a smoke layer from a fire involving the frozen commodity descends to a point 6 feet above the floor in the smallest storage room is 8 minutes 10 seconds. On an undivided floor, the same conditions are not reached until 72 minutes 36 seconds. 4) Second floors of any use with an occupant load of less than 10 are permitted to have only one exit, per Title 24, Part 2, Section 1004.2.3.2 and Table 10A. An aviation control tower with an occupant load of 15 per floor and a maximum area of 1500 square feet is permitted to have only one exit even though it may be unlimited height when of type I-FR construction. The subject building can be classified as type I-FR and the actual occupant load due to the nature of the operations and environmental conditions is approximately 1 per floor. 5) Warehousemen are intimately familiar with the building geography and are equipped with and trained in the use of an emergency escape mask, which provides them up to 20 minutes of escape time through even poisonous gas clouds. 6) There is a written procedure whereby the stair doors in each level are inspected and logged daily to ensure they are not blocked or closed by ice or other obstructions. 7) All employees are trained to deal with an ammonia release as required by the Hazardous Materials . Management Plan and the Risk Management Plan and Prevention Plan which is on file with the City. All warehousemen at this facility are provided with and trained in the use of a two-way transceiver. 8) The likelihood of a release is minimal because of the piping arrangement and the way the evaporators are suspended. The mounting is flexible which allows movement without damage. Any significant leak of ammonia will be detected by the ammonia detection system, which automatically cuts off the feed to the entire warehouse and transmits an alarm to an attended location. Additionally, the ammonia system operates at a below atmospheric pressure (vacuum) of approximately 6 inches. Under the unlikely scenario that if a 1/32 5 of an inch crack in the piping occurred and the leak went undetected, the piping system filled with sufficient incompressibles to take the compressor offline and the system feedback is bypassed and line pressure built to 150 psig, then it would take 11 seconds after the flow reversal before the IPLH concentration would be reached in the smallest room. 9) Flow indication in the sprinkler system sets off a fire alarm to an attended location and automatically notifies the Fire Department. Response to the alarms is immediate evacuation of the building. Additionally, due to the City°s concerns with the building having only one exit stairwell Mr. Dillon has recommended and the owner has agreed to furnish the following mitigation: a) Place emergency escape masks on every forklift truck, this will assure that the mask and the user will remain in close proximity to each other. b) Install notification appliances in every room on every floor -of the refrigerated space to provide audible and visual alarms to the warehouseman upon detection of smoke or ammonia gas in the building. c) Provide a corridor with a 1-hour fire resistive floor -to -ceiling wall assembly from the stairs to the lobby. Openings into the lobby shall be protected with self -closing or automatic closing assemblies of at least 20 minute rating. d) Maintain exit signs and mark an area to assure that no commodities are stored in such a way as to not block egress. Additionally, a permanent rail will be installed to preclude the placement of pallets within 4 feet of the door or its exit path. .Further, Mr. Dillon argues, under CCR, Title 24, Part 2, Chapter 34 division, Section 3401, existing buildings, which were legal at the time of the code, may have their use continued provided such continued use is not dangerous to life. Given the extraordinary low occupant load of the upper floors and basement of the building, the lack of credible ignition, the difficulty of igniting and sustaining a fire in frozen foods, the presence of a sprinkler system, the presence of an ammonia detection system throughout the type of I-FR construction, the familiarity of the occupants with the space, the vacuum operating condition of the ammonia refrigeration system, the routing examination and logging of the stair door condition, the emergency training and apparatus provided for employees and the ability to communicate with employees throughout the building it is Mr. Dillon°s opinion that 6 the building is safe to occupy with a single egress and should not be considered dangerous. The City is in agreement with this position. Therefore, under the alternative design provision of the Uniform Building Code it is recommended that the building be allowed to continue to be occupied with only one means of egress from the upper floors and basement under the following conditions: a) All existing safeguards mentioned in this report and in the January 22, 2001 Dillon Consulting Engineers, Inc.'s letter shall be maintained. b) The above'mentioned mitigation shall be installed within six months of the date of City Council action and shall be maintained for the life of the building. c) The owner shall maintain insurance in the amount of $20,000,000.00 in a form and carrier approved by the City. The City shall be named as an additional insured. d) The type of use of the building shall not be changed. e) The owner shall execute a hold harmless agreement with the City in a form approved by the City Attorney. f) The building shall be available at all times for City inspection to determine continued compliance of all conditions. Failure to comply with any of these conditions may automatically void this approval. Lastly, the City shall have the ability to re-examine this issue in 5 years to confirm or deny the continued occupancy of the subject building. C:\My Documents\STAFF REPORTSWernon.ColdStorage.doc
