We limit the use of flammable materials to areas where no hot work is happening at that time.  (Notice that I didn't say no flammables in the welding area, just not at the same time.  If thaty can't be avoided, we increase ventilation (open doors, etc) to reduce the risk.
Flammable material usage must be addressed on our daily Activity Plans, which address the hazards and preventative actions.

Our anti-spatter spray is water based and dispensed in "pump" bottles.

Our horses are made of HSS 4 x 4 x 1/4 but the ends are capped to prevent sliding an aerosol can inside.  As you know, steel horses take a lot of abuse and we don't want to find spray can under an torch nick.

Maintenance and painting areas are separate from production areas in order to limit the need for using aerosol products near ignition sources.

That's about it.

I have already pulled out all my hair, talked till I get blue in the face and they still keep coming back. All on there own. They just get up and walk over to the weld shop when nobody is looking. I ven cought a small Propane canister wandering around near the weld shop. I think it was headed over to the cutting table.

Officially we do not allow them in the welding Dept. at all. We have a storage area near by but evidently not near enough.

Our guys have them in their desks...hard to keep them totally out of the shop. Cans of galva-bright or penetrant oil are sitting everywhere...

I'd be interested in a policy that worked too, I'll keep an eye on this thread.
