Never turn your back on the fire...
Two interesting things going on here:
1. I learned that you're never supposed to turn your back on the fire - to instead always keep in in sight. They would back out of the building for this reason. I guess this guy is far enough away that this rule doesn't apply...
2. Since heat, fuel, and O2 are needed for a fire, you can remove any of these to put the fire out. Or, as pictured, you can add more to make the fire bigger!
