National Safety Apparel (NSA) — a Cleveland-based manufacturer of protective apparel for industrial safety applications — has introduced a line of flame-retardant (FR) 100-percent cotton knit shirts that offer a single-layer FR solution, eliminating the need to layer garments to combat arc flash-related injuries.

FR Classic Cotton™ Knit shirts are soft, supple and breathable while also featuring an increased arc flash protection of 12 small calories of heat energy per square centimeter — a benchmark that comparable garments previously have been unable to reach, NSA reports.

The shirts are suitable for both indoor and outdoor wear, and are available in a range of colors and styles.
