Which technique is often employed to prevent hazards during a spill response?

The technique of containment is essential during a spill response as it involves confining the hazardous materials to a specific area to prevent their dispersion and further environmental impact. This method ensures that the spilled substances do not migrate into surrounding areas, thereby protecting the environment and public health. Containment can be achieved through various means, such as using barriers, dikes, or absorbent materials, and is a critical first step in managing and mitigating the effects of a spill.

When a hazardous material is contained, it allows responders to implement further clean-up procedures without risking additional exposure or contamination, thus ensuring more effective and safer spill management.
