What safety precaution should be taken when dealing with hybrid or electric vehicles?

The correct choice emphasizes the importance of disconnecting the battery when dealing with hybrid or electric vehicles as a critical safety precaution. Electric and hybrid vehicles contain high-voltage systems that can pose significant risks, including electric shock. By disconnecting the battery, technicians significantly reduce the risk of inadvertently contacting energized components while performing rescue operations or repairs.

This practice is essential because even after the vehicle is turned off, the battery systems can retain charge, leading to potential hazards. Ensuring that the vehicle's high-voltage battery is disconnected helps create a safer working environment for first responders and technicians, minimizing the risk of injury during vehicle extrication or stabilization efforts.

While ensuring adequate ventilation, using standard tools, or waiting for a designated technician may also be relevant in specific scenarios, they do not address the immediate electrical hazards present in hybrid or electric vehicles as effectively as disconnecting the battery does.
