Technician A says to use lineman's gloves when servicing the high voltage system on hybrid electric vehicles. Technician B says that hybrid vehicles have a plug to disable the high voltage system before service. Which technician is correct?

In the context of servicing hybrid electric vehicles, both technicians present valid points.

Using lineman's gloves when working on the high voltage system is crucial for safety. These gloves are designed to provide protection against electric shock, a vital consideration when dealing with the high voltages found in hybrid and electric vehicles. This reinforces the importance of personal protective equipment (PPE) in ensuring technician safety during service procedures.

On the other hand, Technician B's assertion about the existence of a plug to disable the high voltage system is also correct. Most hybrid and electric vehicles are equipped with a service disconnect or a plug that allows technicians to safely disable the high voltage system. This feature is crucial because it helps mitigate the risk of electric shock and ensures that the system is not energized while maintenance or repairs are being performed.

Both elements emphasize the importance of safety protocols in handling high voltage systems. It is essential for technicians to wear appropriate protective gear, such as lineman's gloves, and to utilize safety features like the service disconnect to ensure safe working conditions. Thus, both technicians are correct in their respective statements.
