FOAM EXTINGUISHES FLAMMABLE OR COMBUSTIBLLIQUID FIRES IN FOUR WAYS: 1. Excludes air from the flammable vapors. 2. Eliminates vapor release from fuel surface. 3. Separates the flames from the fuel surface. 4. Cools the fuel surface and surrounding metal

AR-AFFF Foam Concentrate Locations 200 gallons @ Western Ave (Fairchild trailer). 500 gallons on E-2. (Gulf’s) 990 gallons (825 on trailer 165 storage) @ Gulf. 2300 gallons (825 on trailer and 1475 storage & rack) @ Mobil. 3300 gallons (825 on trailer and 2475 storage & rack) @ Citgo. AFFF Foam Concentrate Locations 30 Gallons on E-5 500 Gallons on E-6 SPFD Foam Trailer has 990 Gallons Numerous 55 gallon drums @ Central (2000 gallons) Trailers (2) Portland Pipe Line (1) Sprague (1) Global

AFFF’s are a combination of fluorochemical surfactants and synthetic foaming agents. AFFF’s extinguish fires by forming a aqueous film. This film is a thin layer of foam solution that spreads rapidly across the surface of a hydrocarbon fuel causing dramatic fire knockdown.
10
Alcohol resistant-AFFF foams act as a conventional AFFF on hydrocarbon fuels, forming an aqueous film on the surface of the hydrocarbon fuel. When used on polar solvents (or water miscible fuels), the polysaccharide polymer forms a tough membrane which separates the foam from the fuel and prevents the destruction of the foam blanket AR-AFFF

WATER SUPPLY
12
Basic equation: Area x Flow Rate x Run Time in Minutes (L x W) x (0.16)(15) Example: 1000 Square feet Requires 160 gpm flow25.60 foam per min 155 water per min Total water required = 2400 gallons Total Foam required = 384 gallons
13
Full Surface Hydrocarbon Basic equation: Tank Area x F low Rate x Run Time in Minutes Diameter GPM Flow Foam Concentrate Flow (GPM) Water Flow (GPM) Total Flow (GPM) Total Concentrate Required for 65 min (gallons) 3.14 x r2(0.16)(65) 150 diameter 2826 GPM Flow(85 gpm foam) (2741 water) Total Flow = 183690 Total Foam required = 5511
14
Based on Three hand lines 125 gpm 3% AFFF or AR-AFFF 15 minute application rate 375 gallons of solution x 15 minutes =5625 FOAM = 170 GALLONS WATER= 5455

Tank Size (diameter) Tank 26 is 200 feet Tank 23 is 150 feet Application Rate:.16 GPM per SQ Foot 65 minutes Application Time
24
Tank 23 Foam Solution 2828 gpm Foam needed for 65 minutes = 5514 gallons Tank 26 Foam Solution 5027 gpm Foam needed for 65 minutes = 9802 gallons
