Why in the world would you put your machine in front of the only exit! That was a death trap not a extraction lab. Fuck liquid pours, having your face melted is not worth it.

The other things is that if you watch the video again is that the tower falls over.
Fire, explosion, etc. anything used with flammable solvents that is not stationed
properly (aka sturdy and immovable) is at a risk of falling down and breaking.
