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..
