I don't know if you mean a gas such as oxygen or carbon-dioxide; or "gas", the American colloquialism for petroleum spirit.
Either way the heat could easily make the containers explode very violently by increasing the internal pressure - then the further effects would depend on the flammability or otherwise of the contents.
you get an explosion
Heating an aerosol can is dangerous because it can cause the temperature and pressure inside the can to increase rapidly. This can lead to the can exploding, releasing pressurized contents that can cause injuries or start a fire.
There are pressurised gases in the canister. The heat causes the canister to explode.
If you do it, just be sure to take the same precautions while you transfer it as you would when you were using the aerosol hairspray normally. (Keep away from sparks, flames or heating elements, etc.) This isn't particularly dangerous, but it may be pointless - you will gum up the works of your pump bottle and the pump bottle will probably apply the hairspray too thick and/or very unevenly. [This really shouldn't be categorized under Chemistry =( ]
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.
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.
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.
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:the gas pressure increasesmore of the liquefied propellant turns into a gas
you get an explosion
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.
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.
If you mean an aerosol can then yes.

The hazardous waste code for aerosol cans is typically D001, which classifies them as a hazardous waste due to their ignitability. Aerosol cans can be dangerous if not disposed of properly due to their pressurized contents and potential to explode.
No, you should not throw flour on a grease fire to extinguish it.
