What is the primary use of an arc-rated long sleeve shirt and pants?

The primary use of an arc-rated long sleeve shirt and pants is to provide protection from electrical arcs. These garments are specifically designed to reduce the risk of injury in the event of an electrical arc flash, which can occur during electrical work. An arc flash generates intense heat and light, often resulting in serious burns or other injuries. Arc-rated clothing is made from materials that have been tested and rated for their ability to withstand these hazardous conditions, thereby offering a critical layer of safety for workers in electrical environments. The fabric itself is treated to prevent ignition and to self-extinguish if it does catch fire, making it essential for personnel working near live electrical circuits. This type of clothing is a standard requirement in many industrial and commercial settings where electrical hazards exist, ensuring that workers have the appropriate protective equipment while performing their duties.
