In the case of a derailment, what action should be taken with HAZMAT cars?

In the event of a derailment involving hazardous materials (HAZMAT) cars, the appropriate action is to secure and protect them. This means ensuring the area is safe to prevent any potential releases of hazardous materials and to minimize the risk of fire or other safety hazards. Securing the HAZMAT cars typically includes setting up a safety perimeter and monitoring for leaks or breaches.

Taking this action is crucial to safeguard not just those who may be onsite but also the surrounding community and environment. It helps control the situation until trained emergency personnel can arrive to manage the incident more comprehensively. Given the nature of hazardous materials, it is vital to approach them with proper safety protocols and awareness of the risks involved.

Other options, such as leaving them unattended, moving them to another location, or inspecting for damage, do not adequately address the immediate safety concerns and risks associated with HAZMAT. These tasks could potentially exacerbate the situation or place individuals in harm's way.
