Guide for Selecting Secondary FR Chemical Protective Garments

This guide provides detailed information for employers and workers on selecting effective secondary flame-resistant (FR) chemical protective garments. It emphasizes the importance of ensuring that these garments do not compromise chemical protection while providing secondary FR protection. The document outlines the need to assess both chemical resistance and flame resistance when choosing garments. It describes recognized test methods for evaluating chemical resistance, including ASTM Method F739 and ASTM Method F903, and explains the differences between permeation and penetration tests. The guide also distinguishes between primary and secondary FR garments, detailing their respective purposes and performance requirements. Furthermore, it introduces Tychem® 2000 SFR as a new generation of secondary FR chemical garments designed to meet dual hazard needs, highlighting its unique fabric technology that shrinks away from flame without burning. The document concludes with test results demonstrating the performance of Tychem® 2000 SFR garments compared to traditional options.
