What is the purpose of keeping waste containers closed and properly labeled?

• A. Keep waste containers closed and labeled as 'GARBAGE'.
• B. Leave them open for easy access.
• C. Place them near production lines.
• D. Empty them only when full.

Answer: (A)

Keeping waste containers closed and properly labeled is about preventing contamination and controlling waste flow in a GMP environment. A closed container protects contents from spills, odors, and exposure to airborne contaminants, and it helps prevent pests from accessing the waste. Labeling clearly, such as with a garbage designation, ensures everyone knows how to handle and dispose of the waste correctly and keeps it out of the wrong waste streams. This supports safe, clean production areas and easier audits.

If waste containers are left open, they invite contamination and pest issues and can spread odors. Placing containers near production lines increases the risk of cross-contamination. Delaying disposal until the container is full can lead to overflow and hygiene problems.
