Oh yes. Apparently hydrogen burns at around 2,000C. Thankfully lighter than air, so retreating and dropping to the ground should be effective.

Also the case with methanol. If you google Methanol Car Fire you'll see some videos of drivers from old racing cars that used methanol, with their pit crews struggling to put them out, because they can't see the flames.

Apparently one of the things people who are analysing the Hindenburg fire were looking at was where the flames were - hydrogen being very light would burn above the balloon, and the chemicals on the canvas of the balloon would burn closer to the bag.

Every day a school day.

There are a lot of reasons I like my work, but at least one is that I’m vanishingly unlikely to run into any substance that is invisibly burning at 2,000C.

Mine too!

Indoor work, no heavy lifting, chances of ignition are small.

What's utterly fascinating about the universe is "chance". The odds of all the air molecules in my room randomly migrating to the top north corner (leaving me occupying an explosively decompressed gas vacuum) are vanishingly small... but that's not the same as zero.
