What is the function of a containment system?

The function of a containment system is primarily to prevent the release of hazardous materials into the environment. This is crucial in scenarios where hazardous substances are handled or stored, as any accidental release could lead to severe environmental damage, health risks, and legal ramifications.

Containment systems are designed to contain spills, leaks, or any accidental discharges that may occur as a result of incidents or failures in storage or handling procedures. By effectively isolating hazardous materials, these systems protect surrounding ecosystems and communities from exposure to toxic substances.

Other options mentioned do address important functions but do not align with the primary role of a containment system. Providing emergency medical assistance relates to health and safety protocols, while the safe storage of excess materials is typically handled by other systems designed for material management. Collecting rainwater for reuse pertains to environmental conservation but does not fit within the specific context of hazardous materials management, which is the focus of a containment system.
