ARC flash trousers are designed to provide protection to workers from electrical arcs, which can occur due to an electrical fault or other incidents involving electrical equipment. They are made of materials that can withstand high temperatures and are fire-resistant, such as Nomex or Kevlar.

ARC flash trousers are available in different styles, including traditional trousers, overalls, and coveralls. They may also come with additional features such as reinforced knees, adjustable waistbands, and multiple pockets for storage.

Workers in industries such as electrical utilities, oil and gas, and manufacturing may be required to wear ARC flash trousers as part of their personal protective equipment (PPE) to prevent serious injuries or fatalities in the event of an electrical arc.
