When working with HEVs (Hybrid Electric Vehicles) and EVs (Electric Vehicles), you must create a 10-foot perimeter or buffer zone around the work area that does not have any metal objects. This buffer zone is a crucial safety measure to prevent metal objects from coming into contact with the vehicle's high voltage electrical system, which could cause serious injury or electrical shock. Maintaining this 10-foot metal-free zone helps ensure safety by minimizing the risk of accidental electrical conduction during maintenance or repair work on these vehicles.
This safety practice is widely recommended because HEVs and EVs operate at high voltages (typically between 100 and 600 volts), and contact with these can be dangerous. The metal-free buffer zone helps keep the work area safe by preventing accidental contact with conductive materials.
Therefore, the correct answer is to create a "10-foot" perimeter or buffer zone free of metal objects when working with HEVs and EVs.
