    There’s a hydraulic oil leak right in the upper middle of the frame, aerosolized oil spraying all over the ceiling and falling on hot equipment and igniting. It’s like a grease fire on steroids.

      It’s not oil, its molten aluminum judging from how bright and white the flame is and the fact that the machine is an aluminum bar extruder. People don’t generally realize how insanely flammable aluminum can be when it is reduced to a fine enough powder. Powdered aluminum mixed with an oxidizer is what makes fire crackers go bang. It’s also one of the two main ingredient in thermite.

        Its not just aluminum either. Many powedered metals can do this too. And once it starts, theres no good way to extinguish it. You basically have to let it burn out.

        Im personalty familiar with the effects of titanium

          Very true, I’ve machined titanium before and a titanium fire is not fun. Its a lot more flammable than aluminum as you can ignite larger chips and ribbons of titanium.

          Edit for: words are hard

      I thought it might be oil or coolant. It pops off like a geyser and it was all over in seconds.
