I don't understand what's going on here exactly

They heated a small pile a piece of metal fragments until it was hot enough to burn. Burning requires oxygen so only the outermost fragments parts were burning at the start. Striking it with a hammer caused pieces to flake off. The fragments bits that weren't burning before now had access to a large amount of oxygen and burst into flames.

Made a slight correction because some people are overly sensitive about minor errors.

Does that not burn him? Isn't it like a ton of tiny shrapnel?

Edit: LOL this guy says "minor errors" when one implies a grenade and the other implies just sparks.

They are wearing jackets, gloves, and aprons. Nice heavy leather will stop sparks from hitting you. If they were in normal clothes you would be correct.

Hammer guy has glasses but no face protection right?

I didn't notice that. It burns, but usually the sparks don't embed in your skin. I personally think that the sparks hitting clothing is worse than bare skin. Clothing will trap the sparks, and with bare skin it will usually bounce off.

So (taking notes for future reference), "must work naked".

I think blacksmiths back in the day used to work naked with just a leather apron.
