Not only are there dangers for people who intentionally abuse it, but there are also hidden dangers for people using canned air in regular situations.
Canned air is not really air, it’s a mix of various gases. If canned air is used in a poorly ventilated area there is a possible danger of oxygen deficiency and even asphyxiation for anyone in the room. When canned air is held at an angle the liquefied gas can be released onto surfaces or into the air, creating a highly flammable environment in which open flames, and any kind of spark and even electrical switches can cause a flash fire. The liquid propellant in canned air is known to cause frostbite when skin is exposed for a long period of time, causing serious physical injuries. By contrast, the Canless Air System® O2 is simply air, toxin free, safe and a fraction of the price.
