No- I'm just speaking mostly in general terms-
You didn't mention closing the valve- I'm just saying that shutting it off first thing may keep the tank from exploding if the line is breached
I don't know how you got your pants soaked with gas though- there are a number of commercial stain removers available if you soil yourself otherwise- which AREN'T highly flammable.
and THAT was meant to be condescenDING!
I personally witnessed this crash and the aftermath through binoculars-
the burning man (near the outside wall, moving around at :53 to:57 was actually about the biggest piece left on the track after the wreck- horrible
He died of burns later that summer.
