Carbon tetrachloride has historically been used as a solvent in industrial applications, particularly for cleaning and degreasing metals and machinery. It was also utilized in the production of refrigerants and propellants for aerosol cans, though its use in these areas has significantly declined due to environmental and health concerns. In laboratories, it served as a non-flammable solvent for chemical reactions and extractions. Additionally, it was employed in fire extinguishers, especially for electrical and oil fires, because of its ability to suppress flames without conducting electricity. However, its use has been largely phased out in many countries due to its toxicity and environmental impact.
