Which action is used to keep a hazard from leaving a container and spreading?

• A. Containment
• B. Confinement
• C. Isolation
• D. Mitigation

Answer: (A)

Containment focuses on stopping a hazard at its source by keeping it inside the container and within designed barriers. This directly prevents a release from occurring or spreading to the surrounding area. Confinement is more about restricting movement within a space, not necessarily stopping the hazard from leaving the container. Isolation means separating the hazard from people and the environment, often by distance or enclosure, but it doesn’t inherently stop the hazard from escaping the container itself. Mitigation involves reducing the severity of harm after a release has occurred, not preventing the initial spread. So, containment is the action that keeps the hazard from leaving the container and spreading.
