Define containment in HazMat operations.

Containment in HazMat operations refers specifically to the process of preventing the spread of hazardous materials. This is a critical step when managing incidents involving hazardous materials, as the primary goal is to stop the material from escaping into the environment, which could pose risks to human health and safety as well as environmental integrity.

When containment is successfully implemented, it includes measures such as creating barriers or using absorbent materials to encircle the hazardous substance, thereby ensuring it does not migrate beyond a designated area. This can involve deploying various materials like booms, sheets, or other engineered solutions designed to restrict the movement of liquids, gases, or solids that are hazardous.

Effective containment is essential during any HazMat incident response as it allows for subsequent cleanup or remediation while protecting the public and surrounding environment from potential harm.
