OSHA workplace rules make the use of rubber insulating equipment mandatory, in order to protect workers from electrical shock and arc flash hazards on the job, even when the smallest potential of contact with low or high voltage exists. Employees that work on electrically-energized circuits and equipment use their hands, making them the most susceptible part of the body to electrical shock. Rubber insulating gloves are the only protective gear designed for constant contact with, and protection from, energized conductors and equipment. However, no rubber insulating glove is safe forever. ASTM F496 Standard Specification for In-Service Care of Insulating Gloves and Sleeves require regular inspection and testing of in-service electrical protective equipment. Previously, section 7 of ASTM F496 was subject to interpretation and misunderstanding regarding the maximum test interval for either new gloves or in-service gloves. In 2024, the ASTM Committee F18 (Electrical Protective Equipment for Workers) addressed this issue with an update to the ASTM F496 standard clarifying the difference between new gloves (reference 7.1.1) and gloves previously put into service (reference 7.1.2).
