What does “secondary containment” entail in HAZMAT management?

Secondary containment in HAZMAT management refers to the implementation of systems designed to catch spills that may occur from primary containment. This practice is crucial for preventing hazardous materials from escaping into the environment in case of a leak or spill from the primary container. Secondary containment systems include structures like dikes, trenches, and double-walled tanks, which serve to hold spills and keep them isolated, thus protecting soil and groundwater from contamination. This proactive measure is essential for ensuring safety and compliance with environmental regulations.

The other options address other aspects of HAZMAT management but do not define secondary containment. A single container for hazardous materials does not offer the added protective layer that secondary containment provides. Applying labels is important for identification and safety but does not relate to containment strategies. Regular inspections of primary containers are critical for identifying potential leaks, but they do not constitute secondary containment, which specifically involves additional systems to manage spills.
