Arc-flash protection technology encloses or insulates electrical risks, reducing the risk of injury to individuals working on or near electrical equipment. It protects against electric arcs, which can produce a lot of heat and light. Arc-protection blankets are used to enclose locations where there could be an electrical hazard. When examining powered equipment and responding to emergencies, electrical sticks and rescue hooks protect personnel from electrical charges. High-voltage cables are covered with insulating line hoses to prevent accidental contact with live wires. Shock-protection blankets provide a protective barrier for electrical equipment that is irregularly shaped.
