Flash Fire Rated Garments Complying with OSHA 1910.132 FRC Flash Fire Memo

Flash Fire Rated_Tyndale_J230T

This is the third post of a four-part series where we cover recommendations for compliance with OSHA 1910.132 FRC Flash Fire Memo. 

A second option for garment specification that would meet OSHA 1910.132 standard requirements is to choose garments made from fabrics that are tested according ASTM F1930 at 3 seconds and achieve less than 50% body burn. This option does not meet other NFPA 2112 requirements (see our earlier post on NFPA 2112). ASTM F1930 specifies a standard process for measuring the average predicted body burn of a fabric based on a laboratory flash fire simulation.

Typically these garments do not meet the 3rd party certification criteria required by NFPA 2112, but they also may not meet other criteria (such as 4” char length, HTP rating, zipper/snap requirements, etc). These garments are often sold as “Meets the performance requirements of NFPA 2112” or as “Flash Fire Rated.” An example of a garment that is Flash Fire Rated is the relaxed fit denim jean seen above.

There are three labs in North America that can do the ASTM F1930 manikin test –North Carolina State University, University of Alberta and DuPont. This test method is extremely complex and requires a high degree of technical expertise in both the test set-up and operation. Many fabric manufacturers have their fabrics tested according to the requirements of NFPA 2112, and provide test results for the predicted body burn (which must be less than 50%).

Garments that meet NFPA 2112 may or may not be more protective than Flash Fire Rated garments. The actual degree of protection varies by hazard and by garment.  There are many Flash Fire Rated garments that would likely be more protective than certain NFPA 2112 garments. We recommend that you request ASTM F1930 Flash Fire test reports for any fabric that you approve for use in your organization.

    • Hi Howard, Thanks for reaching out to us. Without knowing more specifics about your company, industry, and hazard analysis, it’s difficult to weigh in definitively. However, generally speaking, safety standards agree the outermost layer must be flame resistant (FR). Layers worn under the outer FR layer should be non-melting at minimum, but it is a best practice for these layers to be FR as well. Please contact us at if there is more information we can provide.
