What Causes Aerosol Cans To Explode?


Aerosol cans, commonly used for products such as hairspray, deodorant, and paint, have the potential to explode if not handled with care. The primary reason behind this explosive characteristic lies in the pressurized nature of these cans.

Inside an aerosol can, the product to be sprayed is stored under high pressure, mixed with a gas known as a propellant. The pressurized conditions maintain the propellant in a liquid state. When the can’s nozzle is pressed, it opens a path for the pressurized contents to escape, and the liquid propellant quickly transitions to a gaseous state, propelling the product out of the can.

However, if an aerosol can is exposed to heat, the pressure inside the can increases rapidly. This could be due to leaving it inside a hot car, near a heat source, or even discarding it in a fire. As the internal pressure rises, the can is at risk of rupturing, which results in a violent explosion as the pressurized contents get forcefully ejected.

Another risk factor is damage to the can itself. Physical force, such as dropping or puncturing the can, can compromise its integrity, leading to a similar outcome as exposure to heat. Hence, it is crucial to handle aerosol cans gently and store them in cool and safe locations.

FAA Regulations For Aerosol Cans In Checked Baggage


According to the Federal Aviation Administration (FAA) regulations, aerosol cans are generally allowed in both carry-on and checked baggage, but there are certain limitations. For personal care or toiletries in aerosol format, such as hairspray or deodorant, the size limit per container typically is 3.4 ounces (100 milliliters) or less. These cans must be securely packed to prevent unintentional activation. 

Aerosols in checked baggage should not exceed 70 ounces (2 liters) by volume. However, certain types of aerosols, such as those used for self-defense, are not permitted in checked bags, and regulations may vary depending on the airline and the specific contents of the aerosol can. As always, it’s recommended to check the most recent FAA guidelines or consult with your specific airline before travel.
