Be safe on your plane - risks with flammable liquids

Some liquids are highly volatile and can have low combustion thresholds and can’t be taken onto planes because there is a risk of them exploding or catching fire harming people and property. It is not safe to take them on the plane – they're 'restricted from carriage'.

Avsec x-rays bags going on planes to make sure there is nothing dangerous in them. If something comes up on the x-ray that needs checking, the bag will be opened and searched.

Most flammable liquids are strictly forbidden. Refer to this table for more information:

70% alcohol by volume

     

 flammable Liquid.3

Alcohol that exceeds 70% alcohol by volume must not be taken on a plane. Alcohol used for cleaning (e.g. isopropyl) or "rubbing" alcohol will likely exceed the 70% limit. Alcohol purchased from a duty free store is likely to be okay.

flammable Liquid.4

Ask your airline if you want to take combustion engines. The engine must not contain any free liquid. If the engine has not been cleaned and all free liquids removed, leave it at home, as it is unlikely to be allowed to travel.
