![]() CHEMGUARD foam concentrates have demonstrated effective firefighting performance with contents stored in the original package under The effective life of CHEMGUARD C3B Concentrate can be maximized through optimal storage conditions and proper handling. If the concentrate freezes during transport or storage, full product serviceability can be restored upon thaw with gentle re-mixing.įactors affecting the foam concentrate’s long-term effectiveness include temperature exposure and cycling, storage container characteristics, air exposure, evaporation, dilution, and contamination. The product should be maintained within the Handline nozzles with fixed eductor/pick-up tubesįor immediate use: The concentrate may also be diluted with fresh or salt water to a 3% pre-mix solution.įor delayed use: Consult Technical Services for guidance regarding suitability of a stored, pre-mix solution (fresh water only).ĬHEMGUARD C3B 3% AFFF Concentrate should be stored in the original supplied package (HDPE totes, drums, or pails) or in the recommended foam system equipment as outlined in Tyco Fire Protection Products Technical Bulletin “Storage of Foam Concentrates”.Fixed or portable in-line venturi type proportioners.Balanced pressure bladder tanks and ratio flow controllers. ![]() Balanced and in-line balanced pressure pump proportioners.This foam concentrate can be correctly proportioned using most conventional, properly calibrated, in-line proportioning equipment such as: The recommended operational temperature range for CHEMGUARD C3B 3% AFFF Concentrate is 35 ☏ to 120 ☏ (2 ☌ to 49 ☌). Medium-expansion discharge devices typically produce expansion ratios from 20:1 to 60:1. Non-aspirating devices, such as handline water fog/stream nozzles or standard sprinkler heads, typically produce expansion ratios from 2:1 to 4:1. Aspirating discharge devices typically produce expansion ratios from 3.5:1 to 10:1 depending on the type of device and the flow rate. For optimum performance, water hardness should not exceed 500 ppm expressed as calcium and magnesium.ĬHEMGUARD C3B Concentrate requires low energy to foam and the foam solution may be applied with aspirating and non-aspirating discharge devices. Environmental Protection Agency 2010/15 PFOA Stewardship Program.ĬHEMGUARD C3B 3% AFFF Concentrate may be effectively applied using most conventional foam discharge equipment at 3% dilution with fresh, salt, or hard water. The fluorochemicals used in theĬoncentrate meet the goals of the U.S. The telomer process produces no PFOS, and these C-6 materials do not breakdown to yield PFOA. This concentrate is only FM Approved in conjunction with the specific proportioning equipment and discharge devices as shown in the Approval Guide (The environmentally-mindful CHEMGUARD C3B 3% AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process. ![]()
