Which statement about BDW container integrity is correct?

• A. A BDW container requires no replacement even if damaged.
• B. A BDW container can be overfilled without risk to safety.
• C. A BDW container should be replaced only when it is completely full.
• D. A BDW container should be replaced when it shows signs of damage, leakage, bulging, or overfilling compromising integrity.

Answer: (D)

The key idea is that keeping the containment intact is essential for safe handling of biomedical waste. A BDW container should be replaced as soon as there are signs that its integrity is compromised—any damage, leakage, bulging, or overfilling that could weaken the container or cause a spill.

This is the best choice because once damage is present or the container is bulging or overfilled beyond its capacity, there is a real risk of leakage or rupture during handling, transport, or storage. Replacing it prevents exposure to hazards for workers and the environment and helps ensure compliance with safety rules.

The other statements miss this safety principle: using a damaged container, or allowing overfilling or continuing use until it’s full, can lead to spills or exposure and is not acceptable practice.
