NSA Acquires Spentex® From GSL

National Safety Apparel (NSA) — a Cleveland-based manufacturer of protective apparel for industrial
safety applications — has acquired the Spentex® brand of flame-resistant (FR) safety apparel from
Global Safety Labs (GSL) Inc. — a Tulsa-based manufacturer of fire protection apparel and fire
suppression products for the petrochemical, electrical power, molten metal, fire service and

base layers, workwear, fleece sweatshirts and outerwear for arc flash and fire protection,
rainwear, high-visibility apparel, and various thermal protection apparel and accessories.

great brand in Spentex and this divestiture allows GSL to focus on our innovative Firebane® fire
