What will be used for disposal of oily waste?

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

Answer: (A)

Oily waste must be contained in a way that prevents fire hazards and leaks. Used oil and oily rags can ignite if exposed to air, so the container needs to keep air out and be robust. A self-closing, airtight metal can provides a secure, fire-resistant enclosure that minimizes vapor buildup and reduces the risk of spontaneous ignition, making it the most appropriate option for disposal.

Open drums allow fumes and air access, which increases ignition risk. Cardboard boxes can't contain liquids and are easily compromised by oil, plus they’re flammable. Plastic bags can leak and don’t seal effectively, offering poor containment for oily waste.
