What is the role of emergency responders when an incident occurs with transported hazmat?

The role of emergency responders during an incident involving transported hazardous materials is primarily focused on quickly and appropriately handling the situation to ensure safety. This involves assessing the nature of the released hazards, containing the spill or leak, and implementing measures to protect public health and the environment. They must act swiftly to minimize the impact of the hazardous material and prevent further harm. This can also include coordinating with other agencies, providing medical assistance if needed, and informing the public about necessary actions.

In contrast, the other options do not capture the full scope of emergency responders' responsibilities. Transporting hazardous materials is not within their purview during an incident; this is generally the role of specialized transport companies under normal circumstances. Evacuating the area might be a necessary action, but it is only one aspect of a broader response plan that includes containment and mitigation efforts. Assessing shipping costs is unrelated to the emergency response and would not be a priority during a hazardous materials incident. Thus, option C encompasses the comprehensive responsibilities of responders in these critical situations.
