Electrical Glove Classification

Electrical glove classification is the system used to rate rubber insulating gloves by their maximum use voltage and performance requirements, enabling workers to match gloves to electrical hazards. In North America, ASTM D120 classes range from Class 00 (500 V AC) to Class 4 (36,000 V AC). Gloves are selected based on highest voltage exposure and used with leather protectors, inspection, and inflation testing as part of a complete electrical PPE program.

On a manufacturing or shop floor, electrical glove classification guides the selection of gloves based on the highest voltage exposure, ensuring workers use appropriate PPE for energized tasks. Gloves are part of a complete electrical PPE program, often including leather protectors to prevent damage, regular inspection, and inflation testing. WorkSafeBC specifies gloves should be at least 14 inches long with an insulation rating of at least 5000 volts for applicable hazards. The class number is a voltage rating boundary, not a measure of comfort or general protection. Gloves may be Type I or Type II, with Type II being ozone resistant. Proper selection and use are critical for compliance and safety.

• ⚠️Using the wrong class for the voltage present, such as selecting a glove below the required maximum use voltage for the circuit.
• ⚠️Skipping inspection or proof testing, even though electrical protective gloves are expected to be inspected and air-tested before use.
• ⚠️Wearing insulating gloves without required protectors or other PPE, which can expose the rubber glove to cuts, abrasion, or arc-related hazards and defeat the protection system.
