ANSUL showcased the NFF 3×3 UL201 non-fluorinated, alcohol-resistant firefighting foam concentrate for Class B firefighting. It offers class-leading, cross-functional performance for fire knockdown and control and extended post-extinguishment burn-back resistance and vapor suppression.
The foam offers effective control and suppression on hydrocarbon fuel fires when used with standard, non-aspirated nozzles and hand lines. It has a viscosity similar to quality 3 x 3 AR-AFFF. It can be mixed using fresh, brackish or salt water. The minimum application rate is 6.5 lpm/m2.
The foam passed with independent third-party witness the UL162 Type III test protocol for an AFFF, demonstrating an increased safety factor.
