What is a secondary containment requirement for certain spilled explosives?

• A. No containment is required.
• B. A drainage system to channel spills to a safe area.
• C. A defined catchment or berm to prevent leakage or runoff from contaminating the environment.
• D. A water-filled barrier around the perimeter.

Answer: (C)

The main idea here is that spills of explosives must be contained so they don’t reach soil or water. A defined catchment or berm creates a physical boundary and a designated area that can collect any spilled material and its runoff. This secondary containment acts as a safety buffer, allowing for controlled cleanup and preventing environmental contamination if a container leaks or breaks. The other ideas don’t provide a reliable barrier or guidance for collecting the spill: no containment would risk spread; a drainage system that channels spills could move hazardous material to a new location; and a water-filled barrier isn’t a standard, practical containment method for spills. So, having a defined catchment or berm is the correct approach to limit leakage and protect the environment.
