Which of the following is not a source of hazardous waste? Radio-imaging wards Dressing room Operation theater Restroom

The question is asking which of the given options is not a source of hazardous waste.

Hazardous waste is any waste that is dangerous or potentially harmful to our health or the environment.

1. Radio-imaging wards: These are definitely a source of hazardous waste. They use radioactive materials for imaging purposes, and the waste produced is considered hazardous due to its radioactive nature.

2. Dressing room: This is not typically a source of hazardous waste. While it can produce waste, such as discarded clothing or packaging, this waste is not typically considered hazardous unless it has been contaminated with hazardous substances.

3. Operation theater: This is a source of hazardous waste. Medical procedures often produce waste that is considered hazardous, such as used needles, surgical gloves, and other materials that may be contaminated with blood or other potentially infectious materials.

4. Restroom: While restrooms can produce waste, it is not typically considered hazardous. The waste produced in restrooms, such as toilet paper and personal hygiene products, is not typically dangerous or potentially harmful to our health or the environment unless it has been contaminated with hazardous substances.

So, the answer to the question is "Dressing room".
