What is a safeguard to minimize toxic releases in a facility?

Double wall construction serves as an effective safeguard to minimize toxic releases in a facility because it provides an added layer of protection against leaks and spills. This design typically involves the use of an inner and outer wall, creating a containment space that can capture any hazardous materials that escape from the primary containment area. This helps contain potential leaks, preventing them from reaching the environment or surrounding areas, thereby reducing the risk of exposure to toxic substances for both workers and the community.

In contrast, single wall construction would not offer the same level of leak protection, as there is no secondary barrier to contain spills. Pressure relief valves can help manage pressure build-up but do not directly prevent leaks. Increased ventilation may help disperse toxic vapors, but it does not address the source of a toxic release; without proper containment measures, harmful substances can still escape. Thus, double wall construction is a robust physical safeguard that directly contributes to minimizing the risk of toxic releases.
