What is one example of a hazard that linemen must protect against?

One significant hazard that linemen must protect against is high temperatures. Working as a lineman often involves being outdoors for extended periods, where exposure to the sun can lead to heat-related illnesses such as heat exhaustion or heat stroke. High temperatures can also exacerbate fatigue, increasing the risk of accidents and injuries when working with heavy equipment or at heights.

Linemen are trained to recognize the symptoms of heat stress and must take appropriate measures, such as staying hydrated, taking breaks in shaded or cooler areas, and wearing appropriate clothing, to manage the impact of temperature on their safety and performance. This awareness and these protective strategies are essential to maintaining safety on the job site in extreme weather conditions.

The other options, while they may present challenges in a work environment, do not pose the same immediate and acute safety risks associated with working at high temperatures.
