Can I take this item on a plane?

Yes. If your airline approves you can take spare non-flammable gas cylinders with you in carry-on or checked luggage. These cylinders are commonly used for inflating bicycle tyres.

What are the restrictions?

  • A limit of four cylinders
  • Each cylinder must not exceed 50ml
  • Must be Division 2.2 gas
  • Your airline must approve carriage

Why is this item restricted?

All cylinders containing pressurised gas present a risk of exploding. It is not safe to take larger cylinders onto the plane.

What happens if I have a restricted item in my carry-on bag?

You will be asked to relinquish all dangerous or prohibited items found in your carry-on luggage. If you refuse:

  • you will not be permitted to move through the screening point, and
  • your airline will be advised of your refusal.

How does Aviation Security screen for restricted items?

AvSec x-ray bags going onto aircraft to ensure there is nothing dangerous in them. If something comes up on the x-ray that needs checking, the bag will be opened, searched and any dangerous good or prohibited item will be removed, with a bag search notification form left within the bag.
