Explosion proof standards for Shot peen bag house

Explosion proof standards for Shot peen bag house

We are having a few companies quote a shot peen machine for our aerospace manufacturing facility.
The topic of dust collection safety with fire suppression came up. We are only peening nickel and steel alloys but there might be a slight possibility to peen titanium in the future. We would like to address this in the beginning part of the process as opposed to an aftermarket system.
What NFPA standards apply ?
We would also contact our insurance carrier for any additional riders needed.

The equipment mfg'r does not know for sure. They thru out NFPA 64, but that is with grain elevators.

Thanks for your help.

RE: Explosion proof standards for Shot peen bag house

even fine particles of most metals will catch on fire under the right conditions. Some of the right are particle size and quantity of combustible dust present so follow NFPA 70 for electrical equipment and wiring subject to combustible dust. You should also consult the OSHA general industry 1910.

If your equipment OEMs are confused as to what is required I'd say that you are in for a wild ride. As a minimum I would recommend that you follow what Chicopee stated above wrt NFPA 70.
