We had a second, not connected, full tank next next to the one we were using
when the flexible connection line failed\ruptured on our gas grill turning
the tank into a large blowtorch spewing an 8 foot flame against the back of
the house. The firemen were unable to approach this tank to turn it off and
we all watched our house burn while waiting for the tank to burn itself out.
When it finally stopped there was about a 10 second lapse before the
pressure relief valve on the 2nd full tank vented, caught fire and we again
stood by and watched our house burn till it finally burned itself out. I
know it was too close to the house....but most are. That's why I now have a
natural gas grill with multiple in-line shut offs.
