Full Description ANSI/ISEA 203-2018 establishes minimum performance and labeling requirements for secondary single-use flame resistant protective clothing. These are commonly used in utility work and refinery maintenance and in steel processing facilities where metal is being cut or welded. Apparel covered by ANSI/ISEA 203-2018 is designed for use in industrial settings where flame hazards may exist and such clothing will not negatively impact the thermal performance afforded by the primary flame resistant protective clothing that is worn underneath. Compliant items are independently evaluated for flame resistance and evaluated for flash fire exposure by layering the garment over a primary thermal garment.
