RE: Security at CDG

pressurised containers can explode if the pressure drops significantly- but hardly ever combustively- explosions are classified as very sudden changes in pressure, and are not always associated with combustion, more like combustion is a secondary effect of an explosion. if you’ve ever put an aerosol can on a fire you notice that it exploded with a large bang, which dissipates most of the energy, and then the contents of the can burnt, in the flames of the fire, very very quickly. if you were to just lower the outside pressure sufficiently to critically fail the can, ie, thin walled pressure vessel, it would just crack, and leak the contents, at worst making your clothes smell of your fave BO buster for months to come. which is why you can carry them in the seating area and not in the hold.

of course the oxygen content in the air could make the gases instantly flammable upon contact………….
