Re: Welding and Gasoline
The danger is the fumes - it could ignite from welding clear on the otherside of the garage!
Make sure there aren't any fumes leaking out anywhere, an old cracked hose could kill you.
Also a good idea to have someone standing by with a fire extiguisher at the ready - just in case the tank ignites and sprays burning gas on you. That way you'll live to tell us about it.
Did you know that fumes that can ignite are NOT always strong enough to smell?
Just last week I was tack welding an external cage in place - then was going to remove it for the final weld. As I was tacking it, sparks ignited the sheepskin seat cover - I had it covered with a welding blanket, but somehow sparks got to it anyway.
Had to replace the seat, cover, and seat belt.
