What is the greatest concern when dealing with vehicle voltage?

The greatest concern when dealing with vehicle voltage is high voltage. High voltage systems, especially in modern vehicles that use hybrid or electric powertrains, pose significant hazards to firefighters and emergency responders due to the potential for electric shock and the risk of electrical arc incidents. High voltage can exceed standard levels and can cause serious injury or even be fatal if proper precautions are not taken.

Understanding the characteristics of high voltage is crucial, as it can also lead to complications when attempting rescues or firefighting efforts in the event of a vehicle crash. Responders must be aware of the systems in vehicles that operate at high voltage and be trained to mitigate the risks effectively. This includes recognizing the features of high voltage systems, the typical locations of components, and the appropriate protective equipment and procedures to implement to ensure safety.
