A gas duster, also known as tinned wind, compressed air, or canned air, is a product used for cleaning or dusting electronic equipment and other sensitive devices that cannot be cleaned using water. This type of product is most often packaged as a can that, when a trigger is pressed, blasts a stream of compressed gas through a nozzle at the top.
Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value.Acute chlorine gas poisoning primarily affects the respiratory system, causing difficulty breathing, cough, irritation of the eyes, nose, and throat, and sometimes skin irritation.
An aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. [1] Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. [2] [3]
Liquified petroleum gas including propane and butane is sometimes used. These all may also be used as a topical anesthetic , due to the numbing effect of cold, though there is risk of frostbite . Cold sprays are sometimes used to carefully freeze and kill attached ticks , with successful application often resulting in the dead tick falling off.
If aerosol cans were simply filled with compressed gas, it would either need to be at a dangerously high pressure and require special pressure vessel design (like in gas cylinders), or the amount of payload in the can would be small, and rapidly deplete. Usually, the gas is the vapor of a liquid with boiling point slightly lower than room ...
Gas dusters often use a bitterant to discourage inhalant abuse, although this can cause problems for legitimate users. The bitterant not only leaves a bitter flavor in the air, but also leaves a bitter residue on objects, like screens and keyboards, that may transfer to hands and cause problems (such as when eating).
The cheap and freely available gas has a molecular weight and fragmentation pattern (base peak 51 m/z in typical EI-MS, [7] major peak at 65 m/z) distinct from anything in air. If mass peaks corresponding to 1,1-difluoroethane are observed immediately after spraying a suspect leak point, leaks may be identified.
In the comedy series Newman and Baddiel in Pieces, Rob Newman's inhaling gas from a foghorn was a running joke in the series. One episode of the Jeremy Kyle Show featured a woman with a 20-year butane gas addiction. [77] In the series It's Always Sunny in Philadelphia, Charlie Kelly has an addiction to huffing glue. Additionally, season nine ...
