I have run across a number of facilities that have a flammable storage room for storage of oil containers. The facilities that I have seen are usually constructed between 1950 and 1980, having the flammable storage use an entrance from the exterior. Most rooms are simple, having explosion proof lighting controlled from a switch on the wall outside. Sometimes I will see a pull station for the fire alarm in the storage room. Recently I have run across a facility with an explosion proof smoke detector and (4) hydrocarbon sampling devices on the walls mounted (2) at the ceiling and (2) at the floor.
I also have two new projects where I have been asked to replace or install a new fire alarm/mass notification system, one larger facility has existing hydrocarbon sampling equipment in the flammable storage room, the other has no existing fire alarm system or hydrocarbon sampling.
I have two questions:
1. It is not clear to me whether hydrocarbon sampling is required in both facilities. What code reference requires the use of hydrocarbon detectors?
2. I generally prefer to avoid installing electrical equipment in hazardous locations. Does NFPA 72 have exceptions for strobes, speakers, or devices that my gut instinct tells me I might like to avoid?
