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:
Aerosols contain pressurized flammable gases or liquids that can explode when exposed to high heat, such as in a fire. This can lead to injuries from fragments being propelled at high speeds and the potential for a larger fire or explosion hazard. For safety reasons, it is recommended to never throw an aerosol can into a fire.
Aerosol cans contain compressed gases that can explode when exposed to high heat, leading to serious injury or property damage. Additionally, the contents of the can, such as chemicals or propellants, can release harmful fumes or react with the fire, creating toxic byproducts. It is safer to dispose of aerosol cans according to local hazardous waste guidelines.
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.
Throwing a can of aerosol hairspray into a fire is dangerous because the pressure inside the can increases as it heats up, potentially causing it to explode. This is not directly related to gas laws, but rather the rapid increase in pressure from the expanding gas inside the can. Additionally, aerosol cans contain flammable propellants that can ignite and create a fireball when exposed to flames.
The heat from the fire can cause the pressure in the can to increase rapidly, leading to an explosion. The metal canister can rupture, releasing the contents forcefully and potentially causing harm to anyone nearby. It is extremely dangerous to put an aerosol can on a fire.

Because it is under intense pressure.

you get an explosion
One that should be thrown into an open fire.
IMO class for aerosol spray cans is Class 2.1, which covers flammable gases. Aerosol products typically contain flammable propellants that can pose a fire hazard. Proper precautions should be taken when handling and storing aerosol spray cans to prevent accidents.
Only if the bus is on 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.
