Our Logic…Our Logic…

• 97% of the fires we encounter are Class A fuels – so carry Class A foam

• For the occasional Class B fire:– Use Class A at 1% - BUT know there is no

sealing capabilityor…

– Call in the local ARFF truck for mutual aidor…

– Let it burn

4

With Ethanol That Logic No Longer AppliesWith Ethanol That Logic No Longer Applies

• Use Class A at 1% - BUT know there is no sealing capability– Class A foam does not work on Ethanol

• Call in the local ARFF truck for mutual aid– The ARFF truck only carries AFFF, which also

does not work on Ethanol

• Let it burn– Dept of Homeland Security has stated the need to

protect critical infrastructure…highways, bridges, railways, ports, etc.

• Class A capability for the majority (97%) of the fires we encounter

Proportioning RatesProportioning Rates

• Ratio of concentrate to water

• Expressed as a percentage– 1.0% = 1 unit of concentrate to 99 units of

water– 3.0% = 3 units of concentrate to 97 units of

water– 0.5% = 0.5 unit of concentrate to 99.5 units of

water

11

Common Proportioning RatesCommon Proportioning Rates

• Class A– 0.1% - 1.0%

• Class B– 1%, 3%, 6%– (1% x 3%), (3% x 6%), (3% x 3%)

(Hydrocarbons x Polar Solvent fuels)

• Emulsifiers / Gels– Varies by manufacturer / usage

Why Is Accuracy So Important?Why Is Accuracy So Important?

• Performance– Ability to make wet, fluid or dry foam (Class A

foam)– Ability to richen for heavy rain (Class B foam)– Ability to seal (Class B foam)

• Logistics

• Cost

• Environmental Concerns (Class B)

16

What Is The Cost Of Inaccuracy?What Is The Cost Of Inaccuracy?

• Let’s assume:– $20 per gallon for concentrate– 5,000 gallons per minute flow rate– 3% proportioning rate– 10% inaccuracy rate

17

The Cost Of Inaccuracy Becomes:The Cost Of Inaccuracy Becomes:

• The logistics of wasted foam:– 15 extra gallons per minute– 900 extra gallons per hour– 9,000 extra gallons per 10 hours

• The cost of wasted foam:– $300 per minute– $18,000 per hour– $180,000 per 10 hours

Let’s Look At BIG WATERLet’s Look At BIG WATER

• Now assume:– $20 per gallon for concentrate– 20,000 gallons per minute flow rate– 3% proportioning rate– 30% inaccuracy rate

19

Now, The Cost Of Inaccuracy Now, The Cost Of Inaccuracy Becomes…Becomes…

• The logistics of wasted foam:– 180 extra gallons per minute– 10,800 extra gallons per hour– 108,000 extra gallons per 10 hours

• The cost of wasted foam:– $3,600 per minute– $216,000 per hour– $2,160,000 per 10 hours

• Flow Rates– At least times 2 or more (especially with Ethanol)

• Flow Durations– Enough water and concentrate to flow at least 50%

longer than the time specified

• Bigger Is Better– One large nozzle generally is more effective than

several smaller ones of equal combined flow

Tips For Sizing EquipmentTips For Sizing Equipment

• Something is not always better than nothing– The size of the hazard determines the requirements

• Size the system to the hazard and size the apparatus to the system– Not the other way around!

• NFPA standards are MINIMUM requirements– Design to succeed

• It’s one thing to develop a plan on paper… it’s another thing to practice it on the fire ground.

• Know for sure…– Safely supply foam solution (flow, distance, duration)

– Pumps– Hose– Nozzles– Proportioners– Concentrate– Manpower
