Which solvent is banned from use due to safety concerns?

The safety status of solvents is tested here: which one has been banned due to serious health risks. Carbon tetrachloride stands out because it is highly toxic, especially to the liver, and is considered a potential carcinogen. Even brief exposure can cause severe liver injury, and long-term exposure raises cancer risk. Because of these grave safety concerns, its use has been restricted or banned in many applications, leading to its replacement with safer solvents. The other solvents listed are hazardous too—methanol is toxic and can cause permanent blindness with exposure, while acetone and ethanol are flammable and toxic in high amounts—but they are not banned across the board. They are still widely used under proper safety controls.
