Hello,
Put the sprinklers in. Also, make sure they are 360 deg (i.e. spray up and down) heads!!. At a previous employer, we had a fire in a cone lined, shield room. We had sprinklers, but they were only 180 deg. (i.e. down). The fire started when some cones on the ceiling came loose and came into contact with a spot light. The fire smoldered for quite some time, before the sprinklers went off. This forced the smoke out the vent holes in the bottom of the room. That is when we noticed the fire. Because the sprinklers were below the cones and did not spray up, the cones just keeps on burning. The fire went up and out the top ventilation opening and into the building ceiling. At about this time, the fire department showed up and put the fire out. As with most fires, the majority of damage was from the water and the smoke. Ned Devine Entela, Inc.

My lab just had an annual inspection visit by our friendly fire hazard inspector. Seems that after 4 successive years of inspections, I suddenly failed this year. The reason is that my 24' x 35' x 10' modular shielded enclosure doesn't have internal water sprinklers. Now I'm all in favor of sprinklers; there's several in the ceiling of the parent room that contains my enclosure. But that doesn't protect the contents of the shielded enclosure. What if a fire started inside the enclosure and then had time to grow? The parent room sprinklers might not be able to stop the blaze then! Never mind that there's almost no fuel within the enclosure; just fire-retardant rated anechoic foam and a 10' long table made out of wood 4x4's. So I don't suppose this is really about common sense. Has anyone recently addressed the issue of fire protection within a shielded enclosure? Or should I move right on to the sprinkler RFQ phase?
