A canned duster is a great way to clear your desk in a jiffy, but what you spray isn't really air, not like what we breathe.
A little awareness helps with compressed gas dusters, according to Safety and Health magazine.
If you've used them, you already know the can gets cold quickly. It can actually cause frostbite. Use the duster briefly and never expose the skin. Don't tilt or shake the can.
Be aware that these compressed gas canisters are highly flammable. Keep cans in an upright position when handling and don't use the spray around electrical outlets, switches, or any open flame, such as a candle on your desk.
In a small, poorly ventilated area, spray can become concentrated and make the atmosphere flammable.
