Q: I was wondering if there was a specific regulation that states exactly where fire extinguisher signs need to be located. Is there a difference between patient area and staff area? Looking over the new Life Safety Code regulations I have not been able to get a specific answer on where signage location is mandatory.
A: The only thing I can find is section 18.104.22.168.2 of NFPA 10-2010, which says where visual obstructions of fire extinguishers cannot be completely avoided, means shall be provided to indicate the extinguisher location. The Annex section says acceptable means of identifying the fire extinguisher locations include arrows, lights, signs, or coding of the wall or column.
So, while there is no direct requirement to install signs over fire extinguishers, you may do so. However, be aware: Some AHJs will expect signs identifying the locations of all extinguishers once you start using signs. Their logic is, if you use signs to identify the location of some extinguishers, then your staff will expect to see signs for all extinguishers.
The AHJs do have the right to interpret the code as they see fit. I suggest you ask your AHJs to see if they would require all of the extinguishers have signs.
