Successfully tested against more than 240 chemicals, the DuPont Tychem garment is lighter weight and less cumbersome than a traditional fully encapsulated suit providing increased vapor and liquid protection. Tychem BR meets the NFPA's highest level of protection within the 1994 Standard, providing first responders an increased level of protection when dealing with chemical, biological or radioactive incidents as well as durability and tear-, puncture- and abrasion-resistance. In addition, the NFPA 1994 Class 2 Tychem BR is specifically engineered for ease of putting on and taking off, thereby making it easy for first responders to complete their work in even the most challenging situations.
