Yeah never stand that close to a giant uncontrolled fire.
Propane Tank Explodes In Truck Bed At Restaurant

This is a video captured from a BBQ restaurant in Lexington, North Carolina, where a 40-pound propane tank in the bed of a truck tipped over, began leaking, caught fire, then exploded. This is the fire and explosion part of the action, which is definitely the most exciting part. Thankfully, nobody was injured in the incident, although I can’t imagine that truck or nearby vehicles were so lucky. Also, I’m not sure who needs to hear this, but this is not how you barbecue North Carolina-style.
