OK do you think you have this condtion??
5.4.1* Extra Hazard (Group 1). Extra hazard (Group 1) occupancies shall be defined as occupancies or portions of other occupancies where the quantity and combustibility of contents are very high and dust, lint, or other materials are present, introducing the probability of rapidly developing fires with high rates of heat release but with little or no combustible or flammable liquids.
If they have uncontrolled dust, the sprinklers maybe the least of their problems. Sounds like they need a dust expert to help them. When u give them the quote for EX 1 vs Ord 2 they will get the idea they may want to get more help and control the hazard.
