U.S. Foam 3% AFFF is a synthetic fire fighting foam concentrate designed for use on non-polar, hydrocarbon hazards when proportioned with water and applied with conventional foam or water/fog equipment. U.S. Foam 3% AFFF provides excellent control and extinguishment of Class B fires by spreading a vapor-sealing film over the liquid fuel. This vapor seal inhibits reflash even when the foam blanket is ruptured and also allows the product to be used to secure non-ignited spills U.S. Foam 3% AFFF provides excellent penetrating and wetting qualities when used on Class A fires this is Important when extinguishing deep-seated fires in wood, paper nlhbel- tires and ordinary combustables.
U.S. Foam 3% AFFF can be used with conventional foam equipment with fresh, sea or brackish water .Self educting foam nozzles and foam nozzles with In-line eductors are among the most common types of hardware for application.
In addition to its use in aspirating foam equipment, U.S. Foam 3% AFFF can be dispensed effectively through non-aspirating equipment Including fog nozzles, water spray devices and standard sprinklers.
U.S. Foam 3% AFFF is effectixe in sub surface injection systems for non-water soluble hydrocarbons. Sub surface injection is safe and reliable for fixed protection of storage tanks.
U.S. Foam 3% AFFF may be applied to tires simultaneously with dry chemical fire fighting agents because the two are compatible.
Effective: Rapid extinguishment reduces the chances of dangerous incidents and reduces the risks to properly and equipment. U.S. Foam 3% AFFF also prevents reflash and burn back, which are major causes of injuries. The securing action of U.S. Foam 3% AFFF minimizes the fire hazard during cleanup of flammable liquid spills.
Reliable: U.S. Foam 3% AFFF can be stored for virtually an indefinite period oftime in approved equipment and systems. NFPA11 recommends annual inspection of all foam systems.
Economical: U.S. Foam 3% AFFF offers faster extinguishment than protein based foams, so less agent is required in training and actual fire emergencies. Its wide range of applications reduces or eliminates the need to nventory other special type agents.
U.S. Foam 3% AFFF concentrates undergo a program of ongoing testing to assess the impact of U.S. Foam products on the natural environment. U.S. Foam products are low in toxicity to tested aquatic organisms (Toxicity information is available from Product Environmental Data sheets, Maternal Safety Data sheets and Toxicity Summary sheets for individual products.)
Aquatic life IIs not adversely affected when U.S. Foam products are used and disposed of properly. U.S. Foam products can be successfully treated In biological waste water treatment systems (Request Product Environniental Data sheets and Disposal Recommendations from your U.S. Foam representative.)
U.S. Foam 1%AFFF may be stored in its shipping container without change in its original phsyical or chemical characteristics. It does not show significant sedimentation or precipitation in storage or after temperature cycling. Freezing and thawing have no effect on performance and the concentrate proportions satisfactorily in ordinary equipment at temperatures above 32°F.
Freeze- thaw cycling may cause slight stratification which may be overcome with moderate agitation. Annual inspections as prescribed in NFPA11 is recommended.
All U.S. Foam products are available in 5 gallon pails, 55 gallon drums or 275 gallon Totes.
