    As the accident and injury data associated with trouble shooting or testing on energized circuits and equipment clearly indicates, this type of work presents a significant risk of hand injury. Therefore, gloves worn in accordance with 75.1720(c) and 77.1710(c) will be required whenever miners troubleshoot or test energized electric power circuits or electric equipment. Work gloves in good condition are acceptable for troubleshooting or testing energized low- and medium-voltage circuits or equipment.
