Containers for storing MPPEH should be _________.

Containers for storing MPPEH should be _________.

• A. Kept upright
• B. Kept closed
• C. Labeled only
• D. Kept outdoors

Answer: (B)

Keeping MPPEH containers closed is essential for safe storage. A sealed container minimizes exposure to air and moisture, protects the contents from environmental contaminants, and reduces the risk of accidental initiation from heat, friction, or tampering. This containment helps preserve the material’s condition and keeps any hazardous vapors or residues securely contained until handling. Simply labeling or keeping a container upright does not provide the same protection, and storing outdoors introduces weather, security, and contamination risks.
