Firefighting Foam Concentrate & Application Calculator

Calculate gallons of foam concentrate and water supply required for hydrocarbon pools, polar solvents, and wildland structural protection.

🚨 Active Fireground Emergency For active structural fires or life hazards, dial immediate emergency dispatch Call: 911 / 112

📋 Standard Operating Guidelines & Verification Protocol

Verified Standards

Verify full PPE compliance and secure personal accountability tags prior to entry. Confirm primary water supply established and verify uninterrupted supply line integrity. Coordinate tactical ventilation with interior fire attack nozzle advancement. Designate Rapid Intervention Team (RIT) equipped with dedicated hose line and rescue air pack. Execute regular Personnel Accountability Reports (PAR) every 15-20 minutes or after tactical shifts.

Foam Science & Vapor Suppression Mechanisms

Firefighting foam extinguishes flammable liquid fires by separating fuel from oxygen, cooling the liquid surface, and suppressing hazardous vapor release. Selecting the correct proportioning rate prevents catastrophic foam blanket dissolution.

Foam Classification Chart

Class A Foam (0.1% to 1.0%): Reduces water surface tension from 73 dynes/cm to less than 30 dynes/cm, allowing deep penetration into porous wildland timber and structural upholstery.
Class B Hydrocarbon (3% AFFF): Forms an aqueous film that floats on petroleum products (gasoline, diesel, jet fuel). Application rate: 0.10 GPM/sq ft for 15 minutes.
Class B Polar Solvents (6% AR-AFFF): Creates a polymeric membrane to resist destruction by water-miscible solvents (ethanol, acetone, isopropanol). Application rate: 0.20 GPM/sq ft for 20 minutes.
