What does segregation mean in explosive storage, and why is it relevant to egress?

• A. Segregation means grouping all materials together to save space; it is not relevant to egress.
• B. Segregation means separating incompatible materials to prevent sympathetic detonation and reduce risk during egress operations.
• C. Segregation means labeling containers with color codes only.
• D. Segregation means storing all items in glass containers.

Answer: (B)

Segregation means separating incompatible materials so they cannot affect each other. This protects against sympathetic detonation and other cascading hazards if a container is breached or heated. When materials are kept apart, an initiating event with one item is far less likely to trigger others, which makes egress safer because people aren’t moving through a field of interacting threats. It’s about preventing cross-contact and reducing the risk to those evacuating, not about saving space, color-labeling, or storing everything in glass. Those other practices don’t address the core safety goal of preventing interactions that could escalate during an escape.
