Working on energized (live) power lines is a highly specialized and dangerous task known as "hotline work." To perform this, linesmen must use specific techniques and equipment to protect themselves from electric shock. One common method, called "bare-hand work," involves the linesman wearing a special conductive suit and being raised by an insulated boom truck to the same electrical potential as the live line. This prevents electricity from flowing through their body. Specialized tools and equipment are also used to insulate workers from the ground and other energized parts. The safety of these operations is paramount, and it is a testament to the extensive training and professional-grade equipment that linesmen rely on every day.
