Take a look at how these two men were dressed for extraction, there was no thought in the world by either of these men that a cataclysmic explosion might take place. The one walking out the door had arms and legs bare as did the man on the ground, both had all skin exposed fried in the 3400+ degree blast, $100 dollars worth of fire protection on the arms, legs and face would have cut the physical injuries to the men more than 70% I bet. Amazon.com and many other places have fire retardant clothing, buy it and wear it for when something really bad happens right in your face; if it can happen it will happen eventually, you're playing with odds and probabilities. Have experts check your rig out, get fire specialists in to take a look, follow their advice you have skin in the game.
Definitely wearing my Flame Retardent gear if I ever blast tane!
