I know that for a fact.
When I was living in Wyoming a very long time ago, I was on the volunteer fire department for the area. We were called out for a 'small' grass/brush fire near a house. Well, it was a bit bigger than little. It was a rural home, with a 1,000 gallon propane tank. There was a good chance the house and shop both would become involved, and both had propane appliances. The fire was getting close to the propane tank so I had my handline guy keeping things wetted down so I could approach the tank and turn the valve off just in case.
Well, he did lay down a decent spread on the path to the tank. I had a bit of a time with the rusted latch on the valve cover of the tank, and then the valve itself. I did get it turned off thought.
Now, part of the problem was my own fault for not maintaining better situational awareness. But the fire was burning around the homeowners outdoor grill, and the LT wanted the propane turned off ASAP, so I let my attention slip a bit and concentrated on the propane tank.
When I turned around after getting the valve shut, my handline guy was nowhere to be seen, and I was now inside a ring of fire. Fortunately, the grass was only three or four inches high, and the brush was spread out pretty good, so the ring of fire fire front was narrow. Even without any type of real turnout gear I was able to run through the fire line without much more damage than some scorch marks. And a really heated attitude.
Fortunately my brother intercepted me before I got to the guy that was supposed to be covering me with that handline. He had seen me go through the fire and headed toward me to see if I was okay. And he knew who it was that was supposed to be covering me. And he knew pretty much how I would feel about it.
So the guy lived to screw up another day, but I went back to Missouri not long after that and never had to work with him again.
