Let’s demystify the mysteries of aerosols on airplanes!
Will Aerosol Cans Explode on A Plane
Aerosols are unlikely to explode on a plane due to regulated pressure and temperature in cargo holds. The FAA permits aerosols in checked luggage with a maximum of 18 ounces per container and 70 ounces total per person. For carry-on, aerosol containers must be 3.4 ounces or less within a quart-sized bag. Always ensure proper packaging to prevent leaks and comply with TSA and airline guidelines.
Will Aerosols Explode In Checked Baggage?
Any aerosol in your checked luggage will not explode in the aircraft’s hold. Even if they become damaged, it’s unlikely.
The Federal Aviation Administration (FAA) states aerosols are allowed in checked baggage in limited quantities for personal care or toiletries. They must be protected with caps to prevent accidental release. The total aggregate quantity per person is typically limited to 70 ounces or 2 liters. Ensure that each container does not exceed 18 ounces or 500 ml.
Products such as sunscreen and non-toiletry aerosols fall under this classification. When packing aerosols in checked luggage, remember that items with a higher risk of explosion or leakage might not be permitted in checked luggage.
- Maximum container size: 18 ounces / 500 ml
- Total allowed quantity: 70 oz / 2 liters
Will Aerosols Explode In Carry On Bags
Any aerosols allowed in carry-on will be perfectly safe.
There are restrictions, though. In your carry-on luggage, aerosols, gels, creams, and pastes must be in containers of 3.4 ounces (100 milliliters) or less and fit comfortably in one quart-sized Ziploc bag. Each passenger is limited to one quart-size bag of liquids, which must be placed separately in a tray when passing through the security checkpoint.
Higher-volume aerosols, including pepper spray cans, are prohibited in carry-on bags. It is imperative to verify that the caps are secure and that the container is leak-proof to prevent any in-flight risks.
- Container size limit: 3.4 ounces / 100 ml
- Bag dimension limit: 1 quart-sized, sealable
My Personal Experience
I have always taken aerosol deodorant on flights in both my carry on (small can) and hold bags. I have never had a problem with them or any other aerosols exploding.
Safe Packing of Aerosols for Flight
When traveling by air, managing your aerosol products is crucial to ensure safety and compliance with regulations. Your aerosols must be appropriately packed to prevent leaks due to accidental activation.
When packing aerosol cans in checked baggage to travel in the cargo hold, it’s wise to use plastic wrap under the lid to ensure it is tightly sealed against leaks as a precaution, or if there is a safety device fitted to the nozzle, then use this. Then, place the canister inside a ziplock plastic bag for added protection. Always double-check that the aerosol is allowed according to airline and TSA guidelines. Regulations may change, so consult your airline to understand their policies before flying.
- Double-seal aerosol caps
- Place aerosols in a sealed plastic bag
- Confirm allowed items with airlines
Here’s why aerosols will not explode on a plane?
There are a few reasons why an aerosol may explode, which include fire, extreme heat, or damage, but under normal circumstances, these conditions will never exist in an aircraft’s hold.
Pressurization in an aircraft seems to be people’s main worry when it comes to wondering if aerosols will explode in the luggage hold.
However, the baggage hold of an aircraft is pressurized just the same as the passenger cabin, so the air pressure will never be very low.
In theory, if the pressure outside the can were to reduce, this may cause the can to explode due to the higher differential in pressures between the inside and outside. In practice, these pressure changes are not something that will happen. Even if the pressurization system on the aircraft failed, the difference would not be enough for an aerosol to explode.
Aerosols would not even explode if taken on a space flight and exposed to zero pressure in space.
Aerosols may explode if exposed to fire as extreme temperatures will arise. As the heat increases, the pressure will increase in the cans due to the expansion of the liquids and expellant. This may get to the point where the structure of the container will no longer be able to cope, and it could rupture.
If there should be a fire in the aircraft’s hold, then you will have bigger things to worry about than whether your deodorant may explode.
Aerosols could burst if containers are punctured by some impact, causing damage. If the aerosol product is packed in a suitcase, surrounded by clothes etc, then this is very unlikely.
Regulations and Guidelines for Aerosols
General TSA Regulations
The Transportation Security Administration (TSA) sets forth regulations for carrying aerosols on planes to ensure passenger safety. You can carry aerosols in your checked baggage, but each container should not exceed 18 oz.
The TSA adopts the 3-1-1 liquid rule for carry-on bags, which permits aerosol containers of up to 3.4 ounces or 100 milliliters packed in a single, clear, quart, zip-lock bag. This rule helps to limit the total quantity of liquids, gels, and aerosols to prevent potential on-board hazards.
FAA Guidelines on Aerosols
The Federal Aviation Administration (FAA) prioritizes the safe transportation of hazardous materials, including flammable aerosols. Aerosols are classified under hazardous materials, and they restrict passengers from carrying any flammable aerosols in carry-on and checked baggage without proper packaging and labeling.
The FAA has extensively researched whether aerosol cans will explode in hold baggage. This is a link to a report for the FAA Technical Center looking into the Hazards of Aerosol Cans in Aircraft Cargo Compartments.
If they are allowed through airport security (or you bought them in a store after the security checkpoint), your aerosols will be perfectly fine in your carry-on bag.
It is perfectly safe if your aerosols are packed in checked bags – they will not explode.
Putting aerosols in checked baggage in a plastic bag would probably be prudent. This is not because they may explode but just in case any aerosols are accidentally activated to prevent contamination of your clothes or other items.
Will an inhaler explode on a plane?
No, your inhaler will not explode on a plane. You can pack it in your checked luggage, but it is probably better to have it in your hand luggage if you need it on the flight.
Will spray sunscreen explode on a plane?
Spray sunscreen will not explode on a plane, whether in pump or aerosol form. You can take spray sunscreen on a plane in your carry on if it is smaller than 3.4 oz. otherwise, you need to place it in your checked baggage.
Will dry shampoo explode on a plane?
No, dry shampoo will not explode on a plane in an aerosol can. You can take it in your hand luggage, but only if they are no larger than 3.4 oz cans; otherwise, you must put it in your checked baggage.
Will bear spray explode on a plane?
Bear spray will not explode on a plane for a good reason. Bear spray aerosols are banned on planes, either in carry-on or checked baggage.
Will pepper spray explode on an airplane?
Pepper spray will not explode on an airplane in an aerosol can. You are not permitted to take any personal defense spray in your cabin bag or through airport security, so you must pack it in your checked luggage.
Will hairspray explode on planes?
No, hair spray will not explode in hand luggage or checked bags on an aircraft. You can take hair spray in your hand luggage, but only if it is no larger than 3.4 ounces; otherwise, it must be packed in hold bags.
Will shaving cream explode on a plane?
Shaving cream will not explode on a plane in carry on bags or checked bags. You can take shaving gels and cream in your carry on but only if it is no larger than 3.4 ounces; otherwise, you must pack it in your checked luggage.
Will a soda can explode in checked baggage?
Soda cans are unlikely to burst or leak in checked baggage unless damaged. If you need to pack them, to be safe, put them in a sealed plastic bag or container so that if they do burst, the contents will not spill over the other contents of your checked bags.
