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

Introducing DuraChem® 500, the game-changing NFPA 1994 solution for terrorism incident response. It’s the only NFPA-certified terrorism response suit to meet one elusive goal: maximum protection at 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.

Besides the hazard protection, DuraChem 500 also protects your budget. Designed as a 'multi-use, single-exposure’ garment, it's much more affordable than expensive reusables.

DuraChem 500 Style 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

  • 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.
