What defensive control techniques are Operations-level responders permitted to perform?

Operations-level responders are trained to implement defensive control techniques that focus on managing hazmat incidents while ensuring safety for both responders and the public. One of the primary methods they can perform includes diking, damming, and diversion.

Diking involves creating a barrier around the hazardous material to contain it and prevent it from spreading further. Damming is the process of blocking the flow of a hazardous substance, which is crucial when dealing with spills in areas like waterways or drainage systems. Diversion techniques are aimed at rerouting hazardous materials away from sensitive areas or preventing them from spreading to uncontaminated zones. Together, these techniques emphasize containment and control of the spill, which are essential for minimizing environmental impact and protecting health and safety during hazmat incidents.

The other techniques mentioned in the other choices—monitoring and capping, overpacking and diluting, and clamping and neutralizing—differ in their applications and the levels of training required for proper execution, with some being beyond the scope of operations-level responders. Thus, diking, damming, and diversion stand out as appropriate techniques that align with the competencies expected of Operations-level personnel.
