What is the name for the method that uses barriers to confine hazardous materials?

The method that uses barriers to confine hazardous materials is referred to as containment. This approach involves using physical barriers, such as dikes, walls, or other structures, to prevent the spread of hazardous substances into the environment, thus minimizing their impact on people and the surrounding area. Containment is crucial during HAZMAT incidents as it helps to isolate the hazardous materials, allowing responders to control the situation and work towards a safe resolution without further exposing the public or the environment to danger.

Understanding containment is essential for HAZMAT incident commanders as it helps in developing strategies to manage spills or leaks effectively while ensuring safety protocols are followed. It is distinguished from other methods, such as diversion, which directs the flow of hazardous materials away from populated areas, but does not necessarily involve physical barriers to encase the substances themselves.
