What is a safety concern when servicing the internal combustion engine of a hybrid vehicle?

When servicing the internal combustion engine of a hybrid vehicle, high voltage is a significant safety concern because hybrid vehicles utilize high-voltage battery systems to power their electric motors. These systems can operate at voltages that are far greater than those found in conventional vehicles, typically around 200 to 400 volts or more. This high voltage can pose a severe risk of electric shock to technicians if proper safety precautions are not followed, especially since hybrid systems often maintain power even after the engine is off.

It is crucial for those servicing hybrid vehicles to be aware of the potential for high voltage and to be trained in the proper safety protocols, such as wearing insulated gloves and using appropriate tools that minimize risk. This recognition of the dangers associated with high voltage is vital in ensuring the safety of automotive technicians during repairs and maintenance of hybrid vehicles.
