You've probably seen this, but if you brush fine steel wool across the terminals of a little old nine-volt batter, it will burst into flames. Alan Barnard Salem, MO Original message From: JBairdRPT at cs.com To: pianotech at ptg.org Received: 8/28/2007 5:52:40 PM Subject: Unexpected fire hazard in shop Today I had a fresh roll of 0000 steel wool catch fire from grinder sparks. Just 5 seconds of low level flame (like alcohol flames) and another 5 second of glowing strands until it went out. Of course it went out -- steel is not a combustible material!! I was using an angle grinder (hand held, and this wasn't piano work). The sparks were shooting about 3 feet across my bench where the roll of steel wool was. If it had been resting on something like paper towel, that might have been more serious. Watch your sparks! John Baird -------------- next part -------------- An HTML attachment was scrubbed...
