Tychem® 2000 SFR protective coveralls provide chemical and secondary flame protection in a lightweight garment. Tychem® 2000 SFR garments are intended to be worn over primary flame resistant garments. In the event that a flash fire occurs, they won't ignite and won't contribute to additional burn injury if appropriate flame-resistant personal protective equipment, such as DuPont™ Nomex®, is worn beneath.

Tychem® 2000 SFR represents a new generation of secondary flame-resistant chemical garment technology. Unlike traditional secondary flame resistant chemical garments that have been available for years, new Tychem® 2000 SFR garments were specially designed to meet dual hazard needs of a protective chemical suit with secondary flame resistance. This unique combination of performance permits Tychem® 2000 SFR garments to be worn over primary flame resistant (FR) garments like Nomex® when chemical splash and flash fire hazards exist. The fabric used in Tychem® 2000 SFR garments is a unique technology. It doesn’t char like traditional secondary flame resistant technologies. Instead, it was designed to shrink away from flame - without burning.



We engineered Tychem® 2000 SFR garments to perform well in flame engulfment scenarios. Extensive ASTM F1930 (instrumented thermal manikin) testing was conducted during the development of Tychem® 2000 SFR garments to aid in garment design and component selection. The final Tychem® 2000 SFR garment continues to demonstrate excellent performance when exposed to a fire engulfment. In fact, when tested side-by-side, Tychem® 2000 SFR garments yield a much lower predicted body burn level and much less afterflame than competing garments, including Lakeland Pyrolon® CRFR. The performance of the actual garment when exposed to a fire engulfment should be the key deciding point for selection of a secondary FR garment. Using ASTM F1930 testing for 4 seconds of flame exposure, when worn over Nomex® IIIA coverall 6oz/yd2, Tychem® 2000 SFR shows 9.3% body burn, versus Lakeland Pyrolon® which shows 28.1% body burn.



Tychem® 2000 SFR coveralls also provide an effective barrier against a range of inorganic acids and bases as well as industrial cleaning chemicals and particles. They're an ideal option for keeping workers safe from chemicals, while not compromising the flame protection of fire-resistance clothing worn beneath them. Applications include: refineries, petrochemical plants, laboratories, hazardous maintenance operations.

ADDITIONAL EQUIPMENT NEEDED

  • Wear other appropriate PPE such as, but not limited to, respiratory, eye, head, hand, and foot protection based on the hazard assessment.
  • Please read, understand and follow the Tychem® User Manual.
  • Tychem® 2000 SFR coveralls provide only secondary flame-resistant protection. They must always be worn over an appropriate primary flame-resistant garment in an environment that needs flame protection, along with other personal protective equipment that protects your face, hands, and feet.
  • This Tychem® 2000 SFR garment (QS128T) has attached socks made of the garment material. These attached socks must be worn inside protective outer footwear and are not suitable as outer footwear. These attached socks do not have adequate durability or slip resistance to be worn as the outer foot covering.
