CZ.'�Y OF WINTER SPRINGS CASE NO.: d8_C�✓'� J r'1 ��_ l� RE: Anderson Coach Works Painting Operations Fire Protection Analysis Dear Mr. Garganese: At your request, I visited Anderson Coach Works in Winter Springs on April 3, 2009 and met with Mr. Anderson. We toured his facility and I have evaluated my observations with the applicable fire protection codes and standards. My understanding is that the operation was permitted in 2003, so the applicable requirements of the 2001 Florida Building Code and the 2001 Florida Fire Prevention Code would have to be followed. The 2001 Florida Fire Prevention Code references NFPA 33 (1995 edition) Standard for Spray Application Using Flammable or Combustible Materials. These references also adopt NFPA 70 which is the National Electric Code (1999 edition). The building is a multi -tenanted light gauge pre-engineered metal building structure using corrugated steel roofing on metal purlins and rigid metal frames. The exterior walls are concrete block. This type of structure offers little fire resistance and can not provide a 1 hour rating, unless additional structural protection is provided. This building is provided with a fire sprinkler system designed to provide an Ordinary Hazard protection level of 0.20 gpm/sq. ft. over the hydraulically remote 1,500 sq. ft. The sprinkler system is supplied by a 4 inch double check backflow preventer and a 4 inch fire riser. NFPA 33 would require the painting area to be designed for an Extra Hazard Group II occupancy which would need to provide a design density of 0.41 gpm/sq. ft. over the hydraulically remote 2,000 sq. ft. (assuming a design area reduction for high temperature 280-286 degree F rated fire sprinklers). The current sprinkler spacing yields approximately 125 sq. ft. coverage per sprinkler. In an Extra Hazard system, the maximum spacing using standard sprinklers would be limited to 100 sq. ft. coverage. We also noted that the 4 inch backflow preventer was improperly installed with PVC pipe above grade. This 4 inch device would, with reasonable certainty, not be adequate in size to provide the water flow at the needed pressures for an Extra Hazard fire sprinkler system. It is unknown if the tenant would be responsible for fire sprinkler upgrades based on its use of the building or if the landlord would be required to provide adequate protection. If the landlord understood what the tenant proposed to do in the building and is responsible for the general area fire sprinkler protection, then a case could be made that the lease should not have been executed. Mr. Anthony Garganese May 19, 2009 Page 2 of 5 Anderson Coach Works has recently reduced its leased space from three bays to two bays. Each of these bays measure approximately 40 feet in width and 50 feet in depth. The eastern (end) bay of the building is used for paint spraying. There is no booth so by default the space becomes a spray room. This "spray room" is separated from the adjacent space by a wall reportedly constructed of studs with drywall covering. As a result of a previous requirement by the fire department, this wall was reportedly covered with a layer of 5/8" Type X fire rated drywall over the existing wall. During my observations, I noted that there is a double door cut through this wall for access to the other bay. This door is a lightweight metal clad door that is not a 1 hour rated door, so the required separation between the spraying area and the adjacent occupancy does not exist. Within the spray room area, I noted that the lighting is provided by standard fluorescent fixtures which do not provide a suitable level of fire or explosion ignition resistance in the spraying areas. A previous attempt was made to improve the situation by installing weather resistant covers over the light switches and the upgrading the fans to ones with sealed motors. Chapter 4 of NFPA 33 provides the minimum levels of protection for the electrical equipment so that it will not pose an ignition hazard. As a general statement, the installed electrical service in the entire spray room will need to be upgraded to meet the requirements of the National Electrical Code specifically to comply with Class I or 11 Division U electrical safety ratings. One of the most obvious conditions was the lack of overspray on the walls, floors and structural members since the operations started in 2003. Based on this observation, it would appear that the two exhaust fans (a third one is abandoned in place) provide adequate exhaust to remove the overspray. At the time of the observations, new filter material was being installed on the fans. I did notice slight discoloration on the fire sprinkler heads above, but it did not appear to be significant (See Recommendations Below). The second occupied bay is used for the preparation and body work repair of the motor coaches in addition to paint mixing. The paint mixing is done in the open and not in a mixing room. I observed approximately 60 gallons of paint stored on open racks along with two metal drums of combustible paint thinner. With the drums of thinner, the maximum storage quantities are exceeded without additional handling improvements. VIOLATIONS OF CODES OR FIRE PROTECTION STANDARDS AND POTENTIAL CORRECTIVE ACTIONS Based on my field observations, I have compiled a list of the fire protection observations that do not comply with the applicable fire codes and standards. This list does not purport to identify every hazard but is believed to identify the significant problem areas. Following each identified problem, I have provided a narrative solution to each of these items: 1. OBSERVED CONDITION: The existing pre-engineered metal building structure does not provide the required 1 hour rating required by NFPA 33 Section 3-1.3. This NFPA standard allows a paint spray "room" if it is constructed of and separated by 1 hour fire resistance construction. With the current roof construction and improper door in the wall, the 1 hour requirement can not be met. Mr. Anthony Garganese May 19, 2009 Page 3 of 5 SOLUTION: A replacement of the door and the application of a 1 hour rated intumescent coating on the roof and structural members could be used to make this spray area comply with Section 3-1.3 of NFPA 33. It does not appear that it would be practical to install a rated ceiling as the building would be too low to allow continued operations. 2. OBSERVED CONDITION: The lighting and electrical fixtures in the spray bay need to comply with the National Electrical Code and be listed for Class I or Class II Division II service. If any electrical equipment or wiring is located in a position that it could be subject to spray, then this electrical equipment would have to meet Class I or Class II Division I service per the National Electrical Code. SOLUTION: All lighting, electrical switches, electrical conduit, conductors, emergency lighting, exit signage, electrical receptacles, and switchgear (existing breakerbox) will need to be removed and replaced with compliant equipment. This equipment will need to meet Class II Division II as a minimum. The electrical switch panel located in the northeast corner of the building needs to be relocated outside the building in a UL listed waterproof box or installed inside the building in an enclosure suitable to provide at least a Class I or II Division II electrical classification. 3. OBSERVED CONDITION: The fire sprinkler system would be required to meet the requirements of NFPA 13 for an Extra Hazard Group II occupancy as specified in NFPA 33 Section 7-2.1. The current system is inadequate and does not appear to be suitable for modifications that could upgrade this system. A removal and replacement of the fire sprinkler system starting at the underground fire mains and backflow device will be needed. SOLUTION: The existing fire sprinkler system will need to be removed from the 2 bays occupied by Anderson Coach works and a new system meeting the requirements of an Extra Hazard Group II occupancy would need to be installed. This will require the installation of a new larger backflow device capable of delivering the needed flow and volume to supply a new 6 or 8 inch fire riser to protect the area occupied by Anderson Coachworks. This assumes that the public water supply can provide adequate flows and pressures, but could not been verified from the site visit which included observations only. 4. OBSERVED CONDITION: The mixing of paints is being done in an open area that is not separated from the other operations as required by NFPA 33 Section 6-3.1. SOLUTION: A self contained mixing room or constructed cut off room must be provided to meet the requirements of NFPA 33. If the total of all combustible paints AND solvents can be maintained below 60 gallons, it would be permissible to mix paints in the spraying area, provided that the other protective features identified in this report. These improvements would include upgrades to the fire sprinkler system and correction of electrical deficiencies. If a mixing room is provided, it must meet the requirements of Chapter 6 as specified in NFPA 33. This will include it being protected with Mr. Anthony Garganese May 19, 2009 Page 4 of 5 automatic sprinklers, containment for spills, ventilation, explosion control electrical features, and bonding of dispensing containers, etc. OBSERVED CONDITION: The PVC plastic air line that penetrates the fire rated wall between the two bays. This piping passes through a wall that is required to have a 1 hour fire rating. SOLUTION: All pipe penetrations through a required fire rated wall or partition must provide the same level of fire resistance as the wall. This penetration by the pipe would have to be protected using an Underwriters Laboratories (UL) approved penetration fire stopping. As a general notation for safety, it is not recommended to run compressed air through hard plastic piping as its failure can result in the release of dangerous plastic shards capable of causing injury or death to the occupants. 6. OBSERVED CONDITION: The existing break room structure in the body shop/ paint mixing area is not fully protected with automatic sprinklers. SOLUTION: The protection in this room needs to be improved by adding sprinklers piped from the existing overhead fire sprinkler system. 7. OBSERVED CONDITION: The fire protection backflow preventer is currently installed with what appears to be either DR-18 or DR-14 PVC plastic piping. SOLUTION: The listing of this material does not allow it to be installed above grade where it would be subject to damage from fire exposure or damage from the sun's UV radiation. The plastic piping needs to be replaced with ductile iron pipe. (Note: This piping would need to be replaced anyway to increase the size of piping supplying the fire sprinkler protection in order to comply with the other recommendations in this report.) 8. OBSERVED CONDITION: The fire sprinklers in the paint spray bay need to be inspected by a licensed fire sprinkler contractor for overspray and replaced as necessary. SOLUTION: From the floor level there appeared to be a minor amount of discoloration on the sprinkler heads that could affect the operation of the sprinklers. POSSIBLE ALTERNATE SOLUTION If this operation could cease the use of solvent based paints and switch to the newer water based automotive finishes, the hazards could be reduced significantly. Without the solvent based paints the electrical equipment would not be an issue nor would the current protection afforded by the fire sprinkler system. No mixing room would be required, the 1 hour wall penetrations and the relocation of the electrical panel would all become acceptable as they now exist. The feasibility of this change would have to be explored by the tenant to determine if it is possible. A review of the internet seems to indicate that the future of automotive finishes is moving toward solvent free materials. Mr. Anthony Garganese May 19, 2009 Page 5 of 5 DISCUSSION AND CONCLUSIONS The current operation does not comply with the applicable requirements of NFPA 3 3 or the references to NFPA 13 (Standard for the Installation Sprinkler Systems) and the National Electrical Code. The unfortunate situation for the tenant is that this building can not be brought up to "code" without the expenditure of a large capital outlay. The fire sprinkler upgrades most likely would have to be completed by the landlord as the required changes would be on the scale of a major demolition of existing piping and its replacement. Other issues such as the need to provide a 1 hour fire rating for the spray area will require protection of the exposed roof steel. We recognize that two probable alternatives exist to upgrade the fire resistance of the roof framing. The first option could be to install fire proofing. An alternative such as installing a ceiling is likely to reduce the building height to unusable elevations and will likely conflict with the existing door height. Virtually all of the electrical wiring and conduit in the bay used for spraying would need to be removed and replaced along with new lighting, including the exit and emergency lighting. The final major deficiency is the paint mixing operation and the lack of a suitable work space complying with NFPA 33. Currently flammable liquids handling, dispensing and mixing do not comply with the applicable requirements of NFPA 33. Based on the total sum of needed improvements, it is likely that the tenant could find a more suitable location for this type operation or explore the alternate solvent free painting options. Unless the landlord is willing to upgrade the fire sprinkler protection, the tenant is not likely to be in a position to bring this building and its current operations into compliance with the applicable codes and standards. I will be available to discuss this matter further at your convenience. Sincerely, Bri oster, F.P.E., Florida Certified Fire Safety Inspector, President cc Project File 3135-09
