What are potential hazards associated with vehicle rescue?

The correct answer highlights a range of potential hazards encountered during vehicle rescue operations that go beyond the obvious risks like fire and smoke. During such rescues, emergency responders must remain vigilant regarding electrical hazards, which can arise from compromised vehicle batteries, live wires, or other electrical systems. Additionally, hazardous materials can be present in accidents involving vehicles that transport chemicals or fuel, posing toxic exposure risks. Structural collapse is another serious concern, particularly if the vehicle is in a precarious position or entangled with other structures, as it can lead to secondary injuries if the rescue operations are not conducted with caution.

While fire and smoke are critical concerns, they are just a subset of the overall hazards present. Traffic congestion can indeed create risks as well, but it primarily affects the safety of rescuers rather than the technical challenges of the rescue itself. High winds and rain can create adverse conditions for responders, but they do not represent as direct or frequent hazards as those indicated in the correct answer, which encapsulate a broader and more immediate range of risks associated with vehicle rescue situations.
