For which classification of rubber insulating gloves is 0.5 inches the required minimum distance to the protector cuffs?

The correct classification that requires a minimum distance of 0.5 inches from the protective cuff to the top of the glove is Class 00 rubber insulating gloves. This specification is part of the standards established for rubber insulating gloves, which are designed to protect workers from electrical hazards.

Class 00 gloves are rated for use up to 250 volts AC and have certain design characteristics, including the cuff height requirement, to ensure adequate safety for the user. The 0.5-inch distance helps ensure that there is no exposure of the wearer's skin to potential electrical hazards, as the gloves are intended to provide maximum protection when working near electrical equipment.

This specific design element is crucial for maintaining safety in electrical work environments, as it helps to prevent accidental contact with energized parts that could lead to serious injuries.
