Gas duster, also known as
canned air, is a product used to clean electronic equipment and other sensitive devices that cannot be cleaned using water. The can comes with a straw to direct the forceful wind that it can produce. The gases inside the can have been compressed to the point that they have become liquid, and they evaporate before leaving the can since the valve draws from the top (unlike most aerosol cans which have a straw that draws from the bottom of the can). Despite the name "canned air," the cans actually contain gases that are much easier to compress into liquids, such as difluoroethane, trifluoroethane, or tetrafluoroethane. Hydrocarbons, like butane, were often used in the past, but their flammability forced manufacturers to use
fluorocarbons.
SafetySince gas dusters are one of the many inhalants that can be easily abused, many manufacturers have added a bittering agent to deter people from inhaling the product. Because of the generic name "canned air", some people mistakenly believe that the can only contains normal air or contains a less harmful substance known as nitrous oxide. However, the gas is denser than air.
Inhaling the gas can cause death, paralysis, or serious injury. Recently, in the United States and Canada stores have begun to ask for ID to verify if the customer is 18 years or older (some include Fred Meyer, Office Max, Office Depot, Staples, RadioShack, Walgreens, Canadian Tire, Shopko, Target, and Wal-Mart).
Men ja det lyder ikke til at det skulle være skide sundt at inhalere.
