Which method serves as a level of protection against electrical hazards besides using a conductive mat?

The method that serves as a level of protection against electrical hazards, besides using a conductive mat, is the use of nonconductive barriers. Nonconductive barriers are materials that do not conduct electricity and are employed to prevent accidental contact with energized parts or conductive surfaces. By acting as a physical separation between personnel and potential electrical hazards, nonconductive barriers enhance safety in electrical environments where exposure to electrical energy is a concern.

This method is crucial because it minimizes the risk of electric shock and can be used in conjunction with other safety measures. While insulative gloves, personal protective equipment, and insulated tools provide additional layers of protection, nonconductive barriers uniquely serve to create a safe distance and shield workers from inadvertent electrical incidents.
