What is the purpose of using secondary containment for chemical storage?

The purpose of using secondary containment for chemical storage is primarily to prevent leaks from reaching the environment. Secondary containment systems are designed to act as a backup to primary containers, such as drums or tanks, which hold hazardous materials. In the event of a leak or spill, the secondary containment ensures that any released chemicals will be contained within a designated area, preventing them from escaping into the environment where they could cause harm to ecosystems, water sources, or human health. This is a critical safety measure in laboratories and chemical storage facilities as it effectively minimizes environmental contamination and enhances overall safety.

The other options do not address the essential function of secondary containment. While reducing space, providing easier access, and categorizing chemicals can be relevant considerations in chemical management, they do not directly relate to the primary safety purpose of preventing environmental exposure to hazardous substances.
