NFPA 2112 was recently updated. The changes made to NFPA 2112 were primarily done to clarify certain areas, add information in areas not previously covered and to keep some of the terminology in line with changes made to NFPA 2113. Keep reading below for a brief summary… 

What is NFPA 2112?

NFPA 2112 is the Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire. This standard outlines the various performance requirements and testing methods for both the FR fabric and FR garments that are needed to be considered in compliance with the standard. It also includes proper labeling and quality control requirements for the FR manufacturers. This is the standard most recognized in the flash fire industry and compliance with it is typically asked for by end users. Although meeting the performance requirements of NFPA 2112 is important, NFPA 2113 is needed to determine what kind of FR you should consider.

 What is NFPA 2113?

NFPA 2113 is the Standard on Selection, Care, Use, and Maintenance of Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire. This standard goes into all the aspects listed in the title but most importantly it goes into detail about how to select an FR garment that is appropriate for the user’s application. Although 2113 comes numerically after 2112 it is in fact the first standard that should be reviewed prior to making an FR clothing decision.

The chapter on selection reviews the first and probably the most important step which is conducting a hazard assessment. The hazard assessment determines both the existence of a hazard requiring FR clothing as well as the level of protection needed. NFPA 2113 does require that FR garments meet NFPA 2112 as the minimum requirement, but the hazard assessment is truly what is needed to determine what type of FR fabric and garments are truly needed.

So, what changed in NFPA 2112? 

The changes seem to fall into five categories:

1. The addition of the phrase “short-duration thermal exposure”
  This phrase was added because some feel NFPA 2112 should be for fabrics and garments to protect against various thermal exposures and not just a 3 second flash fire. Plus there are thermal exposures other than just the initial flash fire that wearers could encounter during and after the initial event.

2. New sections on cold weather insulation materials
   This was added to address questions about what is considered cold weather insulation, how they should perform relative to thermal shrinkage and how to test the insulation materials used in cold weather garments.

3. Clarification of zipper materials
  This section was added to make sure non-FR zipper tape was not used as it could pose a risk to the wearer if ignited.

4. More specificity on what is included in the manikin test
  These changes clarify that only the area covered by the garment, which excludes the hands and feet, are the areas used to determine the body burn percentage. Plus the word predicted was added to the procedure statement; and the word rating was removed as it is not a rating but simply a reported result of the test.

5. A change from TPP (thermal protective performance) to HTP (heat transfer performance).
  The testing method was changed from the NFPA 2112 TTP test method to the ASTM F2700 HTP test method. The HTP test method is considered a more uniform and consistent method. The requirements remain at 6 cal/cm² spaced and 3 cal/cm² in contact.
