I wasn't arguing for light hazard. Only that in my opinion it should be ordinary 1 and not extra as a commercial shop would be. We at Aero have installed sprinklers in well over 300 schools and had to argue with both AHJ's and consultants (present company excluded) over things like running 8" fire lines into classroom buildings. It's a horrible waste of school funding resources.

A commercial woodshop is a step above a school woodshop. We do an awful lot of schools work and you would be amazed at what a modern high school woodshop looks like Mark. Multi station dust collectors are the norm. It's definitely at least an ordinary hazard. A commercial wood shop is Extra Hazard, the debate there being whether it's Group 1 or Group 2.

A typical commercial shop would have sheet goods and lumber inventory for hundreds of cabinets, as well as hundreds of boxed finished goods. A typical wood shop classroom environment would have nothing close to that.

If it has fire load, or processes, or byproduct of those processes that make it more hazardous, then it's more hazardous. Out here in California were used to fire protecting vocational technology and science and shop (auto, wood, metal) classrooms to the higher hazard classification because they may contain pressurized natural gas, welding or soldering, flammable liquids, open burners higher levels of dust, etc. I agree with you - stay the course.

I was told that I was incorrect in my classification since it was a classroom and not a Woodshop Facility. I can not find justification in the standards to down grade the hazard classification to Light or Ordinary I just because the room is a classroom. Am I missing something?
