What is the proper procedure for disposing of hazardous welding solvents and cleaners?

• A. Pour down the drain.
• B. Store near food products.
• C. Follow SDS; store properly; avoid disposal into drains; use approved waste container.
• D. Bury in the yard.

Answer: (C)

Disposal of hazardous welding solvents and cleaners must be guided by the safety data sheet and treated as hazardous waste. The SDS provides specific instructions on how to store, segregate, and dispose of these materials, and it will indicate that disposal down the drain or into soil is not acceptable. These solvents are typically flammable and toxic, so releasing them to the water supply or environment can cause harm to people and ecosystems and may violate laws.

The correct approach is to store the solvents in closed, properly labeled containers, kept in a designated area away from ignition sources and food, and place them in an approved hazardous-waste container. Then arrange disposal through the facility’s hazardous-waste program or a licensed contractor, following the SDS and local regulations. This ensures proper treatment, minimizes environmental impact, and keeps workers safe.

So, the best practice is to follow the SDS, store properly, avoid disposal into drains, and use an approved waste container.
