High-voltage complete sets of equipment require qualifications
Equipment and conductors operating at or below that level fall under one set of installation and work-practice rules, while anything above 600 volts triggers additional requirements for spacing, protective equipment, training, and grounding. 1 The 600-volt dividing point appears. This electrical safety course is designed for high voltage qualified persons. Oriented toward persons performing work near or. OSHA's high voltage standards cover what employers must do to keep workers safe, from lockout/tagout to PPE, and what they risk if they don't comply. Roughly 150 workers die each year in the United States from contact with electricity on the job, and thousands more suffer burns and shock injuries. Working on or above 600V to 69 kV industrial high voltage distribution systems requires qualification.
