Specializing in flame-resistant (FR) and arc-rated (AR) clothing, NSA provides the essential protection required for electrical utilities, oil and gas, and combustible dust environments. At Ohio Power Tool’s Trade Pro Outfitters, we carry the full range of DRIFIRE industrial workwear, featuring moisture-wicking, antimicrobial fabrics that provide permanent FR protection without the heavy, stifling feel of traditional treated cotton.

For workers requiring maximum mobility in the heat, our inventory features TECGEN Select® FR clothing. This specialized fabric is 50% more breathable than competing brands, offering a CAT 2 / PPE 2 rating in a lightweight 5.5 oz material that reduces heat stress while maintaining NFPA 70E and NFPA 2112 compliance. We also stock Vizable® Hi-Vis FR apparel and HydroLite FR rainwear, ensuring that your team remains visible and protected from the elements while meeting strict flash fire and arc flash safety standards.

From NSA arc flash suits and flash fire-rated hoodies to DRIFIRE base layers and button-down work shirts, Ohio Power Tool provides the technical apparel needed for a 24/7 safety culture. Our selection includes the latest 2026 innovations in stretch FR fabrics and ventilated dual-hazard gear designed to move with the worker.
