I am working on an upfit to an existing warehouse building. It is basically a Butler Building with some attached dependencies.
The facility will be using thermoset epoxies in injection molds to create sports equipment on a small scale.
I am working with the building official in a small municipality and want to ensure that I am classifying the building occupancy appropriately.
I received the following feedback from the client:
1) type of epoxy and mold process being used.
> I believe all our epoxy systems are bisphenol ambient cure thermosets. 90% of our molding is closed aluminum tooling. An injection machine takes the two components, mixes and injects them under low pressure. The curing of the parts is accelerated by heating the mold to approx 170f thru the use of heat strips and a pid controller mounted to the mold.
> 2) type of paints being used.
Our paint usage is fairly limited. Typically paint use is just urethane clearcoat and is limited to the" paint room"
> 3) respirators required by manufacturing personnel?
> yes, respirators and eye protection are required if any liquid or grinding is present or occurring
> 4) confirm that max of 12 people are expected to work per shift.
> we don't expect more than 12 people per shift in manufacturing.
I believe that the BOC should be H-4 for buildings which contain materials that are health hazards including corrosives, highly toxic materials, and toxic materials. I believe that the thermoset epoxies qualify there.
I would appreciate any advice or feedback on this.
