Does all fixed/portable/mobile equipment that is installed or enters a Hazardous Location (HAZLOC) have to be “certified” and “labeled” as being acceptable for that specific HAZLOC?
The blunt answer is YES!
But in today’s working world and global economy, I am seeing a lot of foreign approvals for electrical equipment that is not by one of OSHA’s NRTLs. I am also, for the first time in my career, being provided with “certificates” from FM and UL that state in the “fine print”…
