Selecting A Foam Pro System What Types Of

Selecting A Foam. Pro System

What Type(s) Of Foam Concentrate Do You Want To Proportion? • Class A foam concentrates – NFPA 1150 or US Forest Service Approved • Class B foam concentrates – Use of a lower % foam concentrate will increase the discharge capabilities; i. e. , 1%x 3% versus 3%x 6%. – AFFF – AR-AFFF (Viscosity considerations) – Control at each discharge • Emulsifiers – Viscosity considerations 153

What Are Water/Foam Flow Requirements? • What discharges require foam solution? – Pre-connected hand lines, trash lines, etc. – 2 -1/2” and/or larger discharge(s) – Deck gun or aerial waterway (secondary feed) • What are min. & max. GPM requirements of solution? • What are min. & max concentrate levels? • Properly size proportioner, main waterway check valve and flowmeter 154

Class B Foam Sizing Considerations • Performance expectations • NFPA standards • Storage requirements (On and off vehicle) • Logistical requirements • Concentrate proportioning rates • Control at each discharge (Accu. Max single or multi-point injection) 155

Sizing The Proportioner Gallons per minute of foam concentrate required 156

Class A Example • Flow requirements – Maximum: One deck gun 500 gpm – Minimum: One 1 -1/2” 35 gpm (mop up) • Concentrate level requirements – Maximum 1. 0% (exposure protection) – Minimum 0. 3% (initial attack) • Calculate concentrate requirements – Maximum: 500 gpm x 1. 0% = 5 gpm – Minimum: 35 gpm x 0. 3% =. 105 gpm • Choose pump and flowmeter from charts 157

Class B Foam Application Rates NFPA 11 or Manufacturers Rate Fuel Hydrocarbon Polar Solvents Foam Type AFFF or FFFP AR/AFFF Application Rate Formula . 10 gpm/ft 2 @ 1% or 3% Spill Area . 10 to. 20 gpm/ft 2 @ 3% or 6% 50 x 50 = 2500 sq. ft. Critical Application Rate 2500 x. 10 gpm/ft 2 250 gpm 2500 x. 17 gpm/ft 2 425 gpm Total Foam Concentrate on Scene 250 gpm x 15 min x. 01 = 37. 5 or x. 03 = 112 158 425 gpm x 15 min x. 03 = 191 or x. 06 = 382
