During HazMat incidents, what authority do the Incident Safety Officer (ISO) and the Assistant Safety Officer (ASO) share?

The correct choice centers on the authority of both the Incident Safety Officer (ISO) and the Assistant Safety Officer (ASO) to stop unsafe operations during a HazMat incident. This authority is critical because the safety of personnel and the public is the paramount concern during hazardous materials incidents. Therefore, both the ISO and ASO have the responsibility and authority to intervene when they observe conditions or actions that pose a risk to safety. This can include halting operations that are deemed unsafe due to the presence of hazardous materials or other situational factors.

This collaborative authority ensures that the incident's safety protocols are adhered to and that immediate corrective actions can be taken to mitigate risks. It reflects the importance placed on safety within the incident command structure, allowing for a proactive approach to manage hazards effectively. The other options involve roles or responsibilities that may not be equally shared or could depend on specific conditions and protocols established for the response.
