Carry-on details
Not allowed. Fire extinguishers are banned from carry-on bags. Even small personal or automotive fire extinguishers are treated as prohibited compressed-gas cylinders, not as travel gear.
Checked-bag details
Not allowed. Fire extinguishers are also prohibited in checked baggage. The pressurized gas and chemical contents make them hazardous materials that cannot fly in the cargo hold either.
Special instructions
This applies to fire extinguishers of any size, including small car or camping models. If you need one at your destination, buy it there instead of packing it.
FAQ
- Can I bring a small fire extinguisher for my car or RV?
- No. Fire extinguishers of any size are prohibited in both carry-on and checked baggage because they are pressurized gas cylinders. Buy one at your destination instead.
- Why are fire extinguishers banned when other pressurized items are allowed?
- Fire extinguishers combine high-pressure gas with chemical agents, which airlines and TSA classify as hazardous materials unsuitable for air transport in passenger baggage.
