A dispersion of tiny solid or liquid particles in air. Solid areosols are suspended atmospheric particles of less than 1 micrometer in diameter. They are typically found as air pollutants and can travel far from their original source. These solid aerosols can adversely affect health, visibility, and cause damage to materials. Liquid aerosol sprays or mists are typically produced using a propellant to force liquid through a small nozzle. Numerous products, such as paints, consolidants, coatings, adhesives, insecticides, deodorants, and cleaners can be dispersed as aerosols. Propellants are usually hydrocarbons (propane, butane) or dioxide carbon dioxide. Many previously used propellants, such as Freon and chloride vinyl chloride, have been banned.
Synonyms and Related Terms

Hazards and Safety
Explosive danger. Use only in well-ventilated areas. The extremely fine particles in the aerosol can be inhaled, penetrating deeply into the lungs.
