Ignition proof switch near gas regultor

[Kasterko]

Is a waterproof electrical switch, normally gasketed considered an ignition source when closer than the minimum distance from a gas regulator. I'm asking about an exterior radon fan switch being 30" from a gas regulator and I dont know if it's natural or propane but appreciate any help.

Your gas utility or propane supplier may have requirements for the clearance around their equipment to any electrical equipment. Other than that I don't see any reason for that switch to be a problem.

Vent on those regulators can be piped to a different "outlet" location if need be. They only vent minimal gas when they do, not the same thing as a pessure relief valve that may be called upon to discharge a higher volume.

The regulator should only vent when a problem occurs unlike the venting that occurs when filling a propane tank, downwind can smell over a hundred feet at times, not sure the flash concentrations needed in open air space so I would defer to the supplier's specifications on placement of arcing parts.

Water proof is not the same as vapor proof. If your concern is potential ignition from switching, a NEMA 3 waterproof box and cover will not in itself fulfill that requirement for gaseous flammable materials. Determine gas type/supplier, contact them and get in writing any requirements of distance setback of electrical and gas regulator. CYA.
