What action should be taken in the ‘control’ stage of spill management?

In the control stage of spill management, taking steps to prevent further release of material is crucial. This action focuses on immediate containment measures to stop the spread of the hazardous substance, thereby minimizing potential damage to the environment and reducing health risks. By halting the release, responders can protect both people and ecological systems from exposure to hazardous materials.

Addressing the other choices can provide context: notifying stakeholders typically occurs alongside or after containment measures, as they need to be informed but the priority is to manage the spill first. Assessing environmental impact is a necessary follow-up but should only be performed once the immediate threat is contained. Documenting the spill is important for record-keeping and future reference, yet it also comes after ensuring that the situation is under control. Thus, the most urgent action during the control stage is to prevent further release of the hazardous material.
