What term describes actions taken to stop a hazardous material from leaking or escaping its container?

The term that accurately describes actions taken to stop a hazardous material from leaking or escaping its container is "Containment." Containment involves the use of physical barriers or other methodologies designed to prevent the spread or release of hazardous substances into the environment. This can include actions such as sealing leaks, using absorbent materials, or establishing physical barriers to prevent further spread.

Containment is a critical step in hazmat operations because it addresses the immediate threat posed by the hazardous material, ensuring that it remains within a designated area and does not contaminate surrounding environments or harm individuals nearby. By successfully containing a leak, responders can minimize potential exposure and secondary incidents.

While "control" also relates to managing hazardous materials, it is broader in scope and may involve directing cleanup efforts, managing the situation, or overseeing the overall response efforts. "Confinement" suggests keeping the hazard limited to a specific area but does not directly focus on preventing the material from escaping its container. The option "Containment and Control" combines elements of both terms, but the primary focus on stopping a leak specifically aligns with containment.
