What powerline technicians must know to stay safe

BY JIM HUTTER, Capital Safety

Most of modern life is powered by electrical energy, which is why transmission tower work continues to be an integral—yet extremely dangerous—part of the power distribution industry. The Occupational Safety and Health Administration (OSHA) requires that fall arrest or work positioning equipment must be used when working at elevated locations more than four feet (1.2 meters) above the ground on poles, towers, or similar structures if other fall protection has not been provided. There is an exception for “a qualified employee” climbing or changing location on poles,...

For more than a decade, thousands of users have deployed Permanent Electrical Safety Devices (PESDs) to reduce the risks in isolating electrical energy. This elegantly simple innovation increases the probability that workers are only exposed to ‘zero voltage’ when doing an absence of voltage test. The cumulative experience end users have amassed by using PESDs encouraged UL to create a new product specification for permanently mounted Absence of Voltage Testers (AVTs). Because UL acted, the 2018 edition of the NFPA 70E 120.5(N) also included an exception allowing AVTs to be another way to create an electrically safe work condition instead...
