CLASS B FIRE PROTECTION
Fire Protection for Hydrocarbons and Polar Solvents
LCF FIRE AR-AFFF Alcohol-Resistant Aqueous Film-Forming Foam Concentrate is engineered for Class B flammable liquid fires involving hydrocarbons and polar solvents, including alcohols, ketones, and esters. The firefighting foam spreads rapidly across the fuel surface, forming an aqueous film on hydrocarbons and a protective polymeric membrane on polar solvents to reduce foam breakdown and suppress fuel vapors, while delivering rapid fire control, cooling, and burnback resistance.
Designed for fuel storage terminals, oil refineries, chemical plants, and fuel loading facilities, LCF FIRE provides professional foam fire suppression solutions. Available in 1%×3%, 3%×3%, 3%×6%, and 6%×6% formulations to suit different fuel types and foam proportioning requirements.






Freshwater & Seawater Options
Formulation options for freshwater or seawater support industrial, marine, and coastal applications. Seawater suitability is model-specific.
Foam System Integration
Select the appropriate formulation for foam monitors, foam chambers, and foam-water sprinkler systems, with matched proportioning and discharge equipment.
Four Proportioning Options
Available in 1%×3%, 3%×3%, 3%×6%, and 6%×6% formulations for selection by hydrocarbon or polar solvent fuel type and system proportioning requirements.
