Selected properly, insulating rubber gloves will do the job of protecting the worker against electrical shock. Do not forget about leather protectors, for they are an essential part of wearing and using the insulating rubber gloves correctly.
Made of rubber, these are the traditional way to work around arc flash hazards and can be bulky. According to NFPA 70E and CSA Z472 standards, all types of work with shock exposures of greater than 50 volts (V) require the use of rubber insulating gloves.
Rubber insulating sleeves are commonly worn with dielectric gloves in high-voltage applications to provide added insulation from electrical contact for those working on energized equipment.
