Insulating gloves are critical PPE (personal protective equipment) for electrical work on or near exposed energized parts. Insulating gloves must be rated for the voltage to which a worker will be exposed (phase to ground or phase to phase) and marked to indicate their rating. OSHA requires that the gloves must be electrically tested at regular intervals of not more than 6 months. If gloves are not used for one year and are still in the box or bag they must to be sent out for testing after one year. The gloves are then date stamped and the clock starts ticking again. If an employee is found to be using out-of-date gloves, OSHA may issue a fine of up to $500 to the company. National Fuse Products carries a variety of Cementex protective equipment which can be found on our Cementex product page.
