Carl, yrs ago my older brother and his best friend
were working on a tractor tire, guys out there use propane
to air up their tires, any way they were just about finish
and my brother was walking back to his truck to get something and heard the blast, his friend had put the torch one more time to a spot on the wheel and it exploded, he was 34, had 3 kids.. took a long time for my brother to get over the accident. the guy lived a couple of days after getting to hosp..
I told my brother that I thought it was strange to air up a tire with propane, he said it was pretty common with the farmers where he lived.. a little off topic... just be careful around propane also..
There has been more than one welder killed or maimed by welding too close to a tractor tire with nothing but air in the tire. I know of one who was welding on a backhoe close to the tire. The only good thing was that he didn't feel a thing. I don't care about being off topic as long as we are talking about thinking before doing.
