What were they thinking? Putting a 55 gallon fuel drum in an incinerator?
It appears that they took the bung off the drum and placed on the l edge of the incinerator. An empty fuel drum (with the bung off) is very dangerous! A small amount of fuel in the drum can mix with the vapors and form a fireball or jet of pressure. If the flame backs into the confines of the drum an explosion can happen.
In addition to the drum it looks like there is a 5 gallon metal can (fuel?) not far from the drum that looks suspicious.
The big question is why would someone put a fuel drum in
Incinerator when we have large material disposal area?
