Question

Some liquid products are sold in aerosol cans. Gas is stored in a can under pressure and is used to propel the liquid out of the can. Why shouldn't an aerosol ever be thrown into a fireplace or incinerator?

Answer 1

I think you have answered your question. Why should you not place a SEALED, CLOSED container on a gas ring or in a fire?

Explanation:

The aerosol can is sealed, and under pressure. Place it on a heat source, and the gas inside expands. Upon expansion with no outlet, the vessel may explode.

Pressure cookers work on this principle, as food can be cooked at higher temperatures than `100` `""^@C`. Pressure cookers have safety valves, that will operate if the internal pressure becomes too high.
