Which storage practice best aligns with secure material handling?

• A. Shall not create more hazard(s)
• B. Blocked
• C. Stacked
• D. Interlocked

Answer: (D)

Secure material handling relies on storage that prevents unsafeguarded access. An interlock on a storage cabinet or bin ensures the container cannot be opened or the material accessed unless safe conditions are in place, such as doors being fully closed and the area being prepared for handling. This built-in safeguard directly reduces the risk of spills, exposure, or tampering, making it the strongest alignment with secure handling. While keeping hazards from being created is important, and stacking or blocking can be part of storage setup, they do not automatically enforce safe access the way an interlock does.
