Why is secondary containment required for containers in use?

Secondary containment is required for containers in use primarily to prevent spills from spreading to other areas. This safety measure is crucial in managing potential environmental hazards and ensuring workplace safety. When chemicals are stored or handled, the risk of spills or leaks exists. Secondary containment systems are designed to capture any leakage or spills, preventing them from contaminating the surrounding environment.

This practice not only protects the immediate vicinity but also serves to mitigate larger environmental impacts, such as soil and water contamination. By containing spillage, facilities can maintain compliance with environmental regulations and safety standards, which is essential for protecting both employees and the community at large.

The other options do not align with the core purpose of secondary containment. Reducing storage space requirements and ensuring easy access to chemicals do not address the fundamental reason for implementing secondary containment, which is primarily focused on safety and environmental protection. Compliance with insurance policies, while potentially a factor in safety practices, is not the direct intention behind requiring secondary containment in operational settings.
