Does antifreeze container say ‘danger - ‘flamable’ - Do not store near open flame?
sorry. i should have read first.
it gets a flammable label if the flash point is below 73F. With a flash point of 240, it would be “combustible”.
You can burn ethylene glycol, the main ingredient in most antifreeze. Some of those under-the-chafing-dish things are not Sterno but EtGlycol with a wick.
Jet A has a flash point of 100F, corn oil about 450F (don’t try to cook french fries in jet A, is what that means).
So ethylene glycol is more flammable than cooking oil and much less flammable than jet fuel or kerosene.
