Chemguard 3% x 6% AR-AFFF Foam 5 Gallon Pail

Description CHEMGUARD C364 3?6 AR-AFFF (Alcohol Resistant Aqueous Film-Forming Foam) Concentrate combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. This synthetic foam concentrate is intended for firefighting applications at 3% solution on hydrocarbon fuels and at 6% solution on polar solvent fuels in fresh, salt, or hard water. CHEMGUARD C364 foam solution utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance: The foam blanket blocks oxygen supply to the fuel. Liquid drains from the foam blanket and forms either: An aqueous film on a hydrocarbon fire, or A polymeric membrane on a polar solvent fire which suppresses the vapor and seals the fuel surface. The water content of the foam solution produces a cooling effect for additional fire suppression. CHEMGUARD C364 Concentrate is a non-Newtonian fluid that is both pseudoplastic and thixotropic; therefore, dynamic viscosity will decrease as shear increases. The CHEMGUARD C364 3?6 AR-AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process that does not produce PFOS. Approvals, Listings, and Standards CHEMGUARD C364 3?6 AR-AFFF Concentrate is designed in accordance with the National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion Foam. The concentrate is approved, listed, qualified under, or meets the requirements of the following specifications and standards: UL Standard 162, Foam Liquid Concentrates ULC S564, Category 2 Foam Liquid Concentrates Application CHEMGUARD C364 3?6 AR-AFFF Concentrate is intended for use on both types of Class B fires: hydrocarbon fuels with low water solubility, such as crude oils, gasolines, diesel fuels, and aviation fuels; and polar solvent fuels with appreciable water solubility, such as methyl and ethyl alcohol, acetone, and methyl ethyl ketone. It may also be used in conjunction with dry chemical agents to provide even greater fire suppression performance. CHEMGUARD C364 Concentrate can be ideal fixed, semi-fixed, and emergency response firefighting applications such as: Fuel or chemical storage tanks Industrial chemical and petroleum processing facilities Truck/rail loading and unloading facilities Flammable liquid containment areas Docks and on-board marine systems Mobile equipment Foaming Properties CHEMGUARD C364 3?6 AR-AFFF Concentrate may be effectively applied using most conventional foam discharge equipment at the correct dilution with fresh, salt, or hard water. For optimum performance, water hardness should not exceed 500 ppm expressed as calcium and magnesium. CHEMGUARD C364 Concentrate requires low energy to foam and the foam solution may be applied with aspirating and non-aspirating discharge devices. 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 low-expansion discharge devices typically produce expansion ratios from 3.5:1 to 10:1, depending on the type of device and the flow rate. Medium-expansion discharge devices typically produce expansion ratios from 20:1 to 60:1. Proportioning The recommended operational temperature range for CHEMGUARD C364 3?6 AR-AFFF Concentrate is 35 ?F to 120 ?F (2 ?C to 49 ?C) per UL-162. This foam concentrate can be correctly proportioned using most conventional, properly calibrated, in-line proportioning equipment such as: Balanced and in-line balanced pressure pump proportioners Balanced pressure bladder tanks and ratio flow controllers Around-the-pump type proportioners Fixed or portable in-line venturi type proportioners Handline nozzles with fixed eductor/pick-up tubes For immediate use: The concentrate may also be premixed with fresh or sea water to a 3% solution for hydrocarbon fuel fires or a 6% solution for polar solvent fuel fires. For delayed use: Consult Technical Services for guidance regarding suitability of a stored pre-mix solution (fresh wateronly). Storage and Handling CHEMGUARD C364 3?6 AR-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 Johnson Controls Technical Bulletin Storage of Foam Concentrates. A thin layer up to 1/4 in. (6 mm) thick of appropriate-grade mineral oil may be applied to the surface of the foam concentrate stored in a fixed, atmospheric storage container to minimize evaporation. Consult Johnson Controls for further guidance regarding the use of mineral oil to help seal the surface of AR-AFFF concentrates. The concentrate should be maintained within the recommended operational temperature range. Freezing of the product should be avoided. If, however, the product freezes during transport or storage, it must be thawed and inspected for signs of separation. If separation has occurred or is suspected, the CHEMGUARD C364 should be mechanically mixed until homogeneous, and additional testing may be required after mixing to verify product quality. Factors affecting the foam concentrate?s long-term effectiveness include temperature exposure and cycling, storage container characteristics, air exposure, evaporation, dilution, and contamination. The effective life of CHEMGUARD C364 Concentrate can be maximized through optimal storage conditions and proper handling. CHEMGUARD foam concentrates have demonstrated effective firefighting performance with contents stored in the original package under proper conditions for more than 10 years. Mixing CHEMGUARD C364 Concentrate with other foam concentrates for long-term storage is not recommended. Use in conjunction with comparable 3?6 AR-AFFF products for immediate incident response is appropriate. Materials of Construction Compatibility To help avoid corrosion, galvanized pipe and fittings should never be used in contact with undiluted CHEMGUARD C364 3?6 AR-AFFF Concentrate. Refer to Johnson Controls Technical Bulletin Acceptable Materials of Construction for recommendations and guidance regarding the compatibility of foam concentrate with common materials of construction in the firefighting foam industry. Inspection CHEMGUARD C364 3?6 AR-AFFF Concentrate should be inspected periodically in accordance with NFPA 11, EN 13565-2, or other relevant standard. A representative concentrate sample should be sent to Johnson Controls Foam Analytical Services or other qualified laboratory for quality analysis per the applicable standard. An annual inspection and sample analysis is typically sufficient, unless the product has been exposed to unusual conditions.
