Simply a spark skitting across the floor and into light debris is a frequent culprit.
Most of my shop fires start that way.

Angle grinders start a surprising number; not to mention ruining windows far away and not at all in the line of the sparks.

ever seen a CNC lathe cutting titanium literally explode in a ball of fire?
Too many things going on to bother listing them.

I strongly suspect that neither cnc lathes nor titanium are in my future; but it sounds like a lot of fun.

That would be a challenge to extinguish. Compounded by if the building had a fire sprinkler system and any debris on the floor.

Just let go of it, it will eventually unplug itself.

How does a titanium fire respond to water? I know, from personal experience, that the situation described above would border on the impossible to extinguish should the material be magnesium.

If you haven't witnessed water being introduced to a magnesium fire, you haven't lived!

Wise people talk because they have something to say. Fools talk because they have to say something.

Probably 25 years ago our FD crews responded to two burn victims. The father son team who installed chain link fences were putting a fence around a business and using a circular abrasive saw. Some of the sparks went into the dumpster of an adjacent machine shop. The dumpster was filled with magnesium turnings and sparks started the dumpster on fire. The two grabbed a garden hose to extinguish the fire. Both father and son perished that day.

I can imagine that one of the big problems with any "Makerspace" is that everyone thinks they are an "expert" in any field that comes up.
:-( As my one and only (very recent) experience at one of them shows . :-(

There are reportedly some that will not permit you to use any machine in their shop until you sit through their training course on that specific machine.

This is why we have warning labels, like the ones on food, that state: "DANGER! Contents will be hot after heating!"
Today's solutions are tomorrow's problems.
