Aerosols are tiny particles suspended in the air. Aerosols are most commonly associated with spray cans containing household cleaning and personal care products. When the can is sprayed, the product is discharged with the help of a compressed inert gas or solvent, such as flourocarbon (FC).

The danger in using aerosol’s containing flourocarbons, is that they may stay in the human body for long periods of time after being inhaled. FC’s have been found to negatively effect reproductive capacity, human lung health and the environment since the gas released is known to contribute to the level of greenhouse gases.
