What additional equipment must be used if an employee is insulated from energized parts by insulating gloves?

When an employee is insulated from energized parts by using insulating gloves, the use of insulating sleeves is essential to ensure comprehensive protection. Insulating gloves cover the hands and forearms, but without insulating sleeves, the risk remains that electricity could still enter the body through unprotected areas, especially if the glove comes into contact with energized parts or equipment.

Insulating sleeves extend the level of protection further up the arms, protecting the area from accidental contact with energized components. This is particularly important when working in environments where there is a risk of arc flash or shock, as protective gear must cover all exposed skin to effectively reduce the risk of injury.

While safety goggles, hard hats, and rubber boots are certainly important pieces of personal protective equipment (PPE) in their own right, they do not provide the same direct insulation from electrical hazards as insulating sleeves do when working with energized parts. Consequently, the correct answer highlights the importance of comprehensive electrical safety practices.
