You cannot extinguish a thermite fire. It will burn through the floor, cargo containers, and the hull.

Correct. The procedure to fight a thermite fire would be to let it burn.

Once it goes through the floor it will extinguish itself, as the aluminum and hematite will separate.

It will not explode.

If you like thermite, you will love nano-thermite. "Nanoscale composites are easier to ignite than traditional thermites. A nichrome bridgewire can be used in some cases."
