Flame Resistant (FR) Work Shirts & Arc Rated Base Layers

Flame resistant shirts are the foundation of a compliant arc flash or flash fire PPE system. Worn as a base layer or standalone outer garment, an arc-rated FR shirt provides the first line of thermal protection — resisting ignition, self-extinguishing when a flame source is removed, and never melting or dripping onto skin. For workers under NFPA 70E (electrical arc flash) or NFPA 2112 (flash fire) requirements, certified FR shirts are a daily compliance requirement rather than an upgrade.

Our FR shirt collection spans every key work shirt style: long-sleeve woven button-down work shirts in Indura® Ultra Soft, Westex® UltraSoft, and modacrylic/cotton blends for field and plant environments; FR t-shirts and henleys as moisture-wicking base layers; FR knit and polo shirts for supervisors and technicians requiring a cleaner appearance; and hi-vis FR shirts certified to ANSI/ISEA 107 Class 2 for utility linemen, road construction crews, and workers who require simultaneous arc flash protection and visibility compliance. Arc ratings across this category typically range from 4 to 9+ cal/cm², meeting NFPA 70E PPE Category 1 and Category 2 requirements.

Many shirts carry dual certification to both NFPA 70E and NFPA 2112, making them suitable for workers in oil and gas, petrochemical, electrical utility, and general industrial environments. Inherently FR fabrics like Nomex®, modacrylic blends, and TenCate Tecasafe® deliver permanent protection that never washes out; treated FR options in Indura® and Westex® provide comparable performance at a lower cost with proper care.

Use the filters on this page to sort by arc rating, FR certification, style (button-down, t-shirt, polo, base layer), and brand. For a complete head-to-toe FR system, pair with our FR pants or FR bib overalls, and add an FR jacket for cold-weather protection.
