- Chemicals with carbon, chlorine, and fluorine atoms are known as chlorofluorocarbons (CFCs), and they are neither poisonous nor combustible.
- They are employed as solvents, refrigerants, blowing agents for foams and packaging materials, and in the production of aerosol sprays.
- Halons, hydrochlorofluorocarbons, and chlorofluorocarbons all damage the ozone layer, which protects the planet from damaging ultraviolet (UV-B) rays from the sun.
