You should never throw an aerosol can onto a fire or leave it in direct sunlight - even if it is empty. This is because the pressure will build so up so much that the can will burst (and explode if there is a naked flame nearby). There are two reasons for the pressure going up:
Aerosol has fumes that are very flammable. Throwing it into a fire, that is creating a bomb, literally.
Usually there is still air left in the container and when heated the air will start to try to expand and there is a chance of explosion. Its also to avoid liability, because all it takes is one to explode and injure someone for them to have a mess on their hands.
most have flammable chemicals in them and can add to the fire
a fire blanket
Heat causes the gas particles in the can to move faster and farther.

Because it is under intense pressure.
you get an explosion
One that should be thrown into an open fire.

why a fire should never be approached unless it is safe to do so
You should never ignore it.
If you mean an aerosol can then yes.

they get thrown into a landfill and set on fire. then to cover it up, they bury it but the fire is still alive within!
