Containment systems are critical in managing hazardous materials as they function to limit the spread of hazardous substances. This characteristic is essential in situations where hazardous materials are present, as it helps prevent contamination of the surrounding environment, including soil, water, and air. By containing hazardous substances, these systems protect public health and the ecosystem from potential harm.

In scenarios involving spills, leaks, or accidental releases, containment systems are deployed to ensure that the hazardous materials do not migrate beyond a designated area. This can involve physical barriers, such as walls or berms, or practices like using absorbent materials to capture and hold hazardous substances.

In contrast, other options have specific functions that do not align with the primary role of containment systems. For example, while long-term storage is essential for radioactive waste, this does not encompass the broader concept of containment that primarily aims for immediate hazard mitigation. Temporary measures for waste disposal also differ, as those are typically not permanent containment solutions but rather short-term actions. Lastly, thermal treatment pertains to processes designed to treat or neutralize hazardous materials rather than to contain them.
