Our company wants to get training to become certified to clean/decontaminate fire fighter soft goods (we have a large commercial Esporta machine). Upon my many hours of research, it looks like we need to take a certification class that is provided by a Verified third party Independent Service Provider. Does anyone know which ISP providers are… Show more

We are running into a labor issue with a recent healthcare survey of loaded sprinkler heads, my question is how are other places handling the maintenance of cleaning sprinkler heads that are loaded with dust? We have the equipment but are not sure on maintenance intervals or staffing responsibility. We estimate we have around 36k heads in a… Show more
As I understand it, the 13R system can only be installed in Group R. I recently received a sprinkler plan for a school (Group E). The architect insists that a 13R is common practice on the west side of the state if the building is considered a light hazard. In Annex A of the NFPA it evaluates the reasoning for allowing the change from a full 13… Show more
The designer must not be fooled into thinking about the simple function of the space but, rather, must look closely at the contents of the portion of the building being classified to determine the appropriate category. This process is somewhat subjective, and the decision should be discussed with the authority having jurisdiction early in the…

Fellow fire community. I've run up against a conundrum and I'd like some input by others who either actively support laboratories or had supported them in the past. I'm getting a lot of push back from facility management and the users of chemicals - they want to consider chemicals "in-use" if they are left out overnight (or even the weekend) and… Show more
Hello, As far as NFPA 45 goes, a chemical is in use when it is not stored in an approved flammable storage cabinet or approved flammable safety can. For some background, the Technical Committee issued a Formal Interpretation to the 2011 edition of NFPA 45, related to flammable liquid inside a squeeze bottle or spray bottle, in a hood- see…
Recently I did a fire safety walk through Assisted Living and noticed that some tags were missing on some of the doors and hardware. Is there any way to have the tags replaced without replacing these expensive doors and closers? Any help would be appreciated.

NFPA 409 Option 4 of 7.1 for Protection of Group II Hangars. (4) A closed-head foam-water sprinkler system in accordance with Section 7.6. 7.6.1 Closed-head foam-water sprinkler systems shall be designed and installed in accordance with NFPA 16. 7.6.2 The minimum discharge density shall be 6.5 L/min.m2 (0.16 gpm/sq. ft.) of foam solution over… Show more
Both NFPA 16 and 409 are clear - the requirements of the occupancy standard take precedence in any aircraft hangar being protected by a closed head foam water sprinkler systems - "6.5L/min.m2 (0.16 gpm/sqft) of foam solution over the entire storage and service area" the NFPA 16 technical guidance for .17 gpm over 5000sf2 is superseded in all…
I am a building inspector. I have been researching LED lights in closets. They are restricted the same as incandescent lights (12" for surface mounted), while fluorescent lights are considered safer (6"), per NEC 410.16. The builders in my jurisdiction are questioning the code, saying that LED lights are much cooler than incandescent lights. I… Show more
I'm a maintenance planner at a hydroelectric dam. Each of our 11 generating unit main step up transformers are protected by a deluge system (1 deluge valve per transformer). We cannot perform a full flow test without de-energization of the transformer, so we clearly fall under NFPA 25 section 22.214.171.124.3.2, which states that the full flow test… Show more

We are working on a airplane hanger in Cincinnati, OH. The hanger is a Type II hanger protected with a closed head fire suppression system and a foam type system with generators to release/activate the foam. My question is to size the fire pump, do you take the more demanding of the of the two systems? In this case the sprinkler demand is 1161gpm… Show more
You need to consider both systems - the sprinkler system has a specific design area discharge X GPM and the high expansion foam system has a specific demand. You would add these demand together. Since the sprinkler system is thermally activated and there is a fire present some portion of the sprinkler system up to the design area is expected to…
