Class ? Division ? - Rebar Fabrication Facility

[theophilus88]

I am currently working on a warehouse for a rebar production facility. The management team has told me that the facility produces a fine steel powder that gets everywhere when they cut the rebar. Would this fall under a certain Class/ Division from section 500 of the NEC? Thanks in advance for any information!
