Which hazardous solvent is banned from use due to its harmful effects?

Carbon tetrachloride is banned from use due to its significant harmful effects on human health and the environment. It was widely used as a solvent and in fire extinguishers but has been found to pose severe risks, including potential carcinogenic effects and damage to the liver, kidneys, and nervous system upon exposure. Additionally, carbon tetrachloride contributes to ozone depletion, making it a concern for environmental safety. Regulations have been established to limit or eliminate its use, particularly in occupational settings where exposure could occur.
