DIRECTATTACK foam agent concentrate is a Low-, Medium-, and High-Expansion Foam, Class A fire control foam concentrate formulated from specialty hydrocarbon surfactants, stabilizers, corrosion-inhibitors, and solvents. The foam agent solution has been proven effective on many deep-seated Class A fuel fires, such as tire fires, paper fires, coal fires, structure fires, and wild fires. The foam agent also provides superior cold weather performance.
DIRECTATTACK foam agent concentrate can be proportioned from 0.1% to 1.0% in fresh, brackish, or sea water. When used as a pre-mixed solution, only fresh or potable water should be used if the premix is to be stored over long periods of time. Because of the extremely low proportioning rate, the foam agent concentrate offers outstanding economy in concentrate storage space, cost (compared to conventional 3% and 6% foam agents), and water hauling requirements. For example, a 5 gal (19 L) pail of foam agent concentrate produces 500 gal (1,893 L) of fire control foam agent solution at 1% concentration and produces 5,000 gal (18,927 L) of foam agent solution at 0.1% concentration.
Fire suppression mechanisms and characteristics in effect when using DIRECTATTACK foam agent concentrate include:
Applicable suppression mechanisms and some properties of DIRECTATTACK foam agent solution depend on the type of foam delivery device used. The foam agent has a reduced environmental signature and does not have any EPA reportable contents.
DIRECTATTACK foam agent includes the following environmental qualities:
Typical Physiochemical Properties at 77 °F (25 °C)
For comparison purposes, the viscosity of 10W40 motor oil is 160 centistokes at 77 °F (25 °C) and 800 centistokes at 12 °F (–11.1 °C).

Approvals and Listings
The performance of DIRECTATTACK foam agent concentrate is measured against and/or is on the approved list of the following:
NFPA 1150: Foam Chemicals for Fire in Class A Fuels
Canadair Corporation: Approved for use in the CL-215 and CL-415 Aircraft and foam metering systems
USDA Forest Service Specification 307a: Fire Suppressant Foam for Wildland Firefighting
When used with fresh, sea, or brackish water at the correct proportioning rate, the expansion will vary depending on the performance characteristics of the foam making equipment.
DIRECTATTACK foam agent concentrate can be proportioned using most conventional proportioning equipment.
Storage and Handling
DIRECTATTACK foam agent concentrate should be stored in the original packaging supplied (polyethylene drums or pails) or in equipment recommended by the manufacturer as part of the foam system and within the temperature limits specified. The recommended storage temperature for foam agent concentrate is 30 °F to 120 °F (–1 °C to 49 °C).
If the product is frozen during storage or transportation, thawing will allow the foam agent concentrate to be used.
Consult with Tyco Fire Protection Products before mixing DIRECTATTACK foam agent concentrate with other manufacturer’s products.
Materials of Construction Compatibility
Tests have been performed with DIRECTATTACK foam agent verifying its compatibility with the steel, stainless steel, yellow brass, magnesium, and aluminum alloys found in aerial and ground-based firefighting equipment. The foam agent is also compatible with standard fire fighter turn out gear and hose material. The standard procedure for flushing with fresh water should be used with all equipment used with foam agent concentrate or foam agent solution.
