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...

A comprehensive review of IEEE guidelines and documents

Every day, utility workers are risking their lives in work environments that involve high-risk activities such as working at extreme heights, managing or repairing energized high-voltage power systems, transporting dangerous goods, working on suspended access equipment, or the opposite, cramped underground with little ventilation, and mitigating natural disasters.

Although assuring the safety and health of America’s utility workers is the top priority among industry, it is no easy task. Ensuring worker safety involves setting and enforcing standards; providing outreach and education, general site...
