NFPA 1994 Certified Garment Offers Affordable Tactical Protection for CBRN and Hazmat

DuraChem® 500 is the NFPA 1994 certified solution for terrorism incident response. It’s the only NFPA-certified terrorism response suit to offer the combined benefit of maximum protection with an affordable price.

Certified to NFPA Class 1 and Class 2, DuraChem 500 offers CBRN/Hazmat protection in a tactical style garment. In addition to the Chem-Bio requirements, which include warfare agent testing, the 2018 edition of the NFPA 1994 standard also includes general Hazmat response to expand the applications for DuraChem 500. Designed as a 'multi-use, single-exposure’ garment, it is much more economical than expensive reusables.

DuraChem 500 Details

  • Includes dual certification to NFPA 1994 (2018 Edition) for both Class 1 and Class 2.
  • Provides CBRN protection and general Hazmat protection in tactical-style non-encapsulating suit.
  • ‘Multi-use, single-exposure’ garment provides maximum protection at affordable price compared to expensive reusable garments.
  • Unique rear-entry design facilitates doffing to eliminate cross-contamination concerns.
  • Elastomeric face opening gasket fits securely around respirator, eliminates need for taping.

Going To Extremes! Video Evidence Shows Life-Saving Technology.

Pyroman test dramatically illustrates the life-saving performance of DuraChem 500.

Kappler is committed to user survivability, and DuraChem 500 garments are subjected to intense testing to simulate real-world exposure in a chemical flash-fire, which can generate heat up to 1900º F. The Pyroman Thermal Manikin test for DuraChem 500 was conducted at North Carolina State University, with a 3-second test to predict a percentage of body burn a wearer might experience. Sensors on the manikin indicate not only the area of the body affected, but also predict severity of the burn. The DuraChem 500 encapsulating suit provided outstanding performance for both measurements, with 0% body burn indicated.
