If mitigation efforts are failing or the situation is getting worse, what should the incident command do?

• A. Original plan must be reevaluated and possibly revised
• B. Continue exactly as outlined in the original plan
• C. Increase the scale of the same strategy without changes
• D. Defer decisions to post-incident analysis

Answer: (A)

When a hazmat incident is unfolding and mitigation efforts are not achieving results or conditions are getting worse, the incident command must re-evaluate the plan and revise it as needed. The Incident Action Plan is intended to be dynamic, guiding actions for the current situation, and it should be updated to reflect new information, changing risks, and resource needs. Reassessing allows you to shift tactics, adjust containment and protective actions, modify zones, change PPE levels, and reallocate or request additional resources to address the evolving threat safely and effectively.

Continuing exactly as the original plan would ignore new hazards or constraints, and escalating the same approach without adapting may fail to contain the issue. Waiting for post-incident analysis would delay critical decisions during active response and could put responders and bystanders at greater risk.
