Intrinsically Safe Wiring

[Loss Control Consultant]

Hi Group,

Can you folks tell me if, under normal operating circumstances, is intrinsically safe wiring (explosion proof receptacles and light fixtures) required in a welding booth?

We have a tech school near here that has what looks like to me to be explosion proof light fixtures in the booth they use for stick and gas welding, but the receptacles are the standard 15 amp residential type.

Any opinions / help you can offer will be greatly appreciated!!!

There is no such thing as an intrinsically safe light fixture or receptacle.
I see no reason for welding booth to require explosion proof wiring methods. Are you sure the fixture is not just a vapor proof for protection of the lamp?

Thanks for the guidance. You're right. I'm not sure the existing light fixtures are explosion proof. This demonstrates my lack of knowledge. I am probably not even using the term "intrinsically safe " correctly.

intrinsically safe is an installation that ensures that the electrical installation and equipement involved in the installation are so designed that it can not produce a spark in the exsplosive enviroment it is installed in..I hope I have described that correctly..
