Which container type is used for the disposal of oily waste in the work area?

• A. Open drums
• B. Cardboard boxes
• C. Plastic bags
• D. Self-closing air tight metal cans

Answer: (D)

Oily waste can emit flammable vapors, so containment must minimize vapor release and prevent spills. Metal containers hold up against the solvents in oily waste and reduce ignition risk. A self-closing lid keeps the container closed to limit vapor buildup and accidental contact with the waste. Open drums allow fumes to escape and can lead to fires, cardboard boxes can soak through and burn or leak, and plastic bags may rupture or leak. Therefore, using self-closing air-tight metal cans provides the safest, most compliant option for oily waste disposal in the work area.
