Which combination of practices addresses reactivity hazards during storage and transfer?

• A. Using high-temperature storage only
• B. Sealing containers and avoiding venting
• C. Inerting to reduce oxygen exposure, bonding/grounding during transfer, venting when needed, and using compatibility charts to segregate incompatible chemicals
• D. Never test or rotate stocks

Answer: (C)

Managing reactivity hazards during storage and transfer means controlling conditions that can trigger dangerous reactions: limiting oxygen or oxidizer exposure, preventing ignition sources, avoiding pressure buildup, and keeping incompatible chemicals apart. The best approach brings several protective practices together: inerting to reduce oxygen exposure, bonding and grounding during transfer to prevent static sparks, venting when needed to relieve any pressure or gas formation, and using compatibility charts to segregate incompatible chemicals. Inerting lowers the chance of oxidizer–fuel or other reactive interactions, bonding/grounding stops potential ignition during handling, venting prevents container rupture or sudden releases by safely removing built‑up pressure, and compatibility charts provide a clear guide to keep dangerous pairs from sharing the same space. Together, these measures address both storage and transfer hazards and reduce the likelihood of hazardous reactions. Practices like relying on high temperature alone, sealing without venting, or neglecting stock rotation don’t address the full range of risks and can create new ones.
