Buying Guide: Class 4 Rubber Electrical Gloves
Class 4 rubber insulating gloves are selected for high-voltage electrical applications where protection up to 36,000V AC is required. The glove class should always match the voltage exposure, task requirements, and the employer’s electrical safety procedures.
Because these are Type 1 gloves, they are not ozone-resistant. Proper storage, inspection, and retesting are important parts of maintaining rubber insulating glove performance. Workers should check gloves before use for punctures, cracking, swelling, deterioration, or any condition that may reduce electrical insulating protection.
