I ferry Part 91 jet/propjet aircraft across the Atlantic and as aprevious pilot noted: DO NOT CARRY IT IN THE CABIN. That stuff is dangerous and lethal, in Europe the ground crews can not even touch the stuff you have to do it.
A military amunition can will protect from explosion but not the gas released, the propellant is either (excuse spelling).
I carry 2-3 cans in the baggage compantment outside the cabin structure and in a airtight blast container. I also fill out a hazardous manifest but have never had to show it but rules change and its a good CYA.
