is canned air flammable?
‘Canned air‘ is not the air you breathe. Canned–air products contain a gas that is mostly compressed into a liquid. A variety of gases are used in these products and some are highly flammable. One example of a commonly-used, highly-flammable gas is difluoroethane.
What chemicals are in canned air?
The usual gases found in canned air are difluoroethane, trifluoroethane, tetrafluoroethane, or butane. Butane is an interesting choice because it’s flammable, so using canned air to cool hot electronics may not be a wise decision (see my burning bubbles project if you need convincing about potential flammability).
