Which of the following criteria for discarding approved cardboard and plywood containers is FALSE?

• A. Ensure only explosive labels are present
• B. The container is intact and not leaking
• C. Exterior labeling is legible
• D. The container shows no signs of damage

Answer: (A)

Disposing of approved cardboard and plywood MPPEH containers centers on keeping the container safe and ensuring clear hazard communication. If the container is intact and not leaking, it means there’s no rupture risk and no immediate exposure to contents. Exterior labeling being legible ensures anyone handling the container sees the correct hazard information and can take proper precautions. The container showing no signs of damage reinforces that there hasn’t been compromising impact, corrosion, or wear that could cause leakage or accidental release.

The statement about ensuring only explosive labels are present isn’t a valid discard criterion because labeling must convey accurate and complete hazard information, not just a single type of label. Other required markings or safety information may be present and must be legible and appropriate for disposal. Requiring that only explosive labels be present could obscure other important markings or create confusion about how the container should be handled or disposed.
