What type of clothing is advised for linemen to prevent electrical hazards?

Flame-resistant (FR) clothing is essential for linemen because it is specifically designed to protect against the hazards presented by electrical arcs and fires. In the event of an electrical incident, FR clothing will resist ignition and self-extinguish, thereby reducing the risk of severe burns and injuries. This type of clothing does not melt or drip, which is critical in protecting the skin from harmful thermal effects.

In contrast, waterproof jackets and pants, while useful in wet conditions, do not provide the necessary protection against electrical hazards. Standard work uniforms may lack the protective qualities specifically needed for environments where linemen are exposed to high-voltage equipment. Thermal underwear, while important for warmth in cold weather, does not offer protection against electrical risks, which are a primary concern for linemen. Therefore, FR clothing is the most appropriate choice for ensuring safety in the electrical work environment.
