I've had magnesium cuttings flash off. Working in an electric motor shop.
.125 thick parting tool, about three inches deep into cutting the end ring off of a rotor.
Oil/coolant can clogged or ran low. You couldn't get that cross slide (hand) cranked out fast enough to avoid the fire.
Roughly a grocery sack worth of fluffy ribbon shavings.
Looks sort of like a giant flash cube going off in slightly slow motion

I figure it must be AI - what would be fueling that fire, unless you're cutting magnesium, zirconium, or some such? Cooling fluid is generally non-flammable. May there was a hydraulic rupture?

Don't forget the old smelly sulfur loaded brown oil we used to use.

That company that made people learn to weld a bandsaw blade, the lead man and foreman said that they kept fire extinguishers near the milling machines, during the war.
Gang milling and swapping parts with the spindles running.
The man they paired me up with for orientation period, had a missing finger and some scars.

Hydraulic oil powering the B/C axis, Divinol Lithogrease lubricating most friction surfaces.

Though yes, it might be AI.

That almost happened for real at the dealership I worked at. There was a service campaign to replace the gas tanks on Sienna vans. The official procedure was to pump out the fuel with a gas buggy. Of course, since we were getting like .7 warranty hours to do a 2.5 customer pay hours job we took a shortcut by drilling a hole in the bottom of the plastic tank with an air powered drill. Well, one guy decided to do that with an electric drill. I heard a sickening woosh, a bluish flash, and in a split second every fire extinguisher in the shop was being discharged in that bay. Everybody in the shop apparently cashed out the remainder of their life's good fortune as the fire was stopped almost as soon as it started.
