Flash point and boiling points are different. The flashpoint of ammonia is 270F. Below this temperature at 1 atm, ammonia will not catch fire no matter what.

That video took place in an engine room, so any combination of heat, flame, or spark is possible.

“Flash point is the temperature a liquid (usually a petroleum product) will form a vapour in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame”

If ammonia is boiling (and producing a fog) of concentrated vapor which then burns/explodes in exposure to an open flame, which it will definitely do at even OF, that is an entirely academic point no?

It still has the same effect.
