Which waste is classified as halogenated waste?

• A. Waste containing toluene
• B. Waste containing Acetone
• C. Waste containing Dichloromethane
• D. Waste containing Ammonia

Answer: (C)

Halogenated waste is waste that contains halogen atoms (such as chlorine, fluorine, bromine, or iodine) in its chemical structure. This often includes chlorinated solvents, which require special handling because they can be toxic and can form hazardous gases during disposal. Dichloromethane contains chlorine atoms, so it is a halogenated waste. The other options—toluene, acetone, and ammonia—do not contain halogens in their structures, so they are not classified as halogenated waste.
