Aerosols are pressurised so please remember: Do not pierce aerosols, even when they are empty, because there is always some pressure, and possibly some of the product left. It may be flammable or cause injury if you pierce the can. The pressure inside the can increases greatly in the heat and may cause it to burst.
Is it safe to puncture an aerosol can?
If it sparks, it can potentially ignite the propellant as it depressurizes through the hole. That’s why only non-sparking or spark-resistant tools should be used to puncture aerosol cans safely. Using a screwdriver to puncture an aerosol can makes it impossible to comply with all these requirements.
Why is it important not to puncture an aerosol can?
Why is it important to not puncture an aerosol can? The pressure of the gas inside of the can is greater than the pressure of the outside so it would have to equalize which means that the can will explode.

How do you fix an aerosol can that won’t spray?
If it still doesn’t spray, hold the can upside down after shaking it for a minute or so, then spray it again. The pressure buildup should release the softened matter clogging the nozzle. If it still doesn’t clear, remove the nozzle again and push a thin pin or needle into the spray hole.
