Which of the following is NOT considered an environmental hazard to watch for while on the job?

Radiation exposure is not typically categorized as an environmental hazard that substation technicians encounter during their routine job activities in substation environments. The other options represent more common hazards that workers might face on-site.

Tripping hazards, such as uneven surfaces or equipment on the ground, are prevalent in substation settings where technicians must navigate various obstacles, making awareness crucial to prevent falls and injuries. Cold injuries concern temperature-related issues, common in outdoor settings where workers can be exposed to extreme weather conditions, leading to risks like frostbite or hypothermia. Sunburn, similarly, is a concern for outdoor workers who are exposed to direct sunlight for extended periods, requiring precautions to protect against ultraviolet (UV) radiation.

While radiation exposure can be a serious concern in certain industries, it is less relevant for substation technicians compared to the more immediate and practical environmental hazards they face on the job.
