FR Fabrics

The below chart outlines some of the basic qualitites ofFR Fabrics used in making arc flash and fire resistant clothing. We hope that this chart will provide valuable information about popular

Fire Resistant materials such as Nomex IIIA, Indura Ultra Soft, and Protera and will help you determine the appropriate arc flash clothing type that would work best for your particular

application.

Please check out ourFR Clothing Requirements page for hints in selecting the proper level ofArc Flash PPE for a specific task. That page provides guidelines on selecting FR Clothing types

for specific jobs and the different ways that fire resistant clothing is rated. Once you know what type ofarc flash clothing orarc flash kit you need to get, please visit our internet store Legion

Safety Products for a wide selection ofFR Clothing. And if you do not find the exact fire resistant garment that you would like to get, please dont hesitate to call us.

The Initial Cost on the below FR Fabric Guideline is the comparison of cost of a FR garment made of a spe cific material compared to the same made from another material. The Life Cost

includes the cost of maintaining the garment combined with the Initial Cost. Thus, an FR Coverall made from expensive material that lasts for a long time and is easy to maintain (launder, etc) can

have a low Life Cost.

The information provided in this chart is based on the literature from Workrite Uniforms, which provides extensive information about arc flash clothing and standards governing requirements of fire

resistant clothing on job sites.
