CAT 4 Overalls

CAT 4 overalls are the highest level of arc-rated flame-resistant (FR) protective clothing, designed for extreme-risk environments where exposure to severe electrical hazards is possible. With an arc rating of 40 cal/cm² or higher, these overalls meet NFPA 70E Category 4 standards and are essential for workers involved in high-voltage tasks, power generation, and heavy industrial maintenance. Built from advanced multi-layer FR fabrics, CAT 4 overalls offer maximum thermal protection while maintaining durability and mobility. Features like storm flaps, reinforced seams, and secure closures further enhance safety, making them a critical piece of PPE for the most hazardous jobs.
