Electrical Power Installers and Repairers

Line workers who install and repair electrical transmission and distribution infrastructure face fatality rates of 19–23 per 100,000. Electrocution from high-voltage lines (up to 765,000 volts on transmission lines) can kill instantly or cause severe internal burns; falls from transmission towers and utility poles add a second major hazard. Storms that require emergency power restoration push workers into the most dangerous conditions — energized lines on the ground, flooded substations, and zero visibility.
