USDA Approved Knockdown® Class A firefighting foam arms firefighters taking an offensive approach when attacking wildfires. Knockdown improves penetrating capability by reducing the surface tension of water to reach deep-seated fires, thus providing quicker knockdowns with less water. The unique blanketing properties of Knockdown make it an effective solution for ground attack operations, building a fire line, prescribed burning, and mop-up operations. An ideal blend for air attacks, Knockdown provides accurate and dependable proportioning through all types of onboard injection systems. Knockdown can be used with fresh, brackish and sea water, and exhibits good foamability, even in extremely cold water. Formulated for Class A/B foam systems and excellent for use in Compressed Air Foam Systems (CAFS), Knockdown is USDA approved, U.L. Listed and meets NFPA 18 Standard for Wetting Agents.
