1 1 Ethanol… The New Hazard In Town Part II: Foam Delivery Bill Ballantyne

2 2 What Municipal Fire Departments Typically Prepare For…

3 3 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 capability or… –Call in the local ARFF truck for mutual aid or… –Let it burn

4 4 With 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.

5 5 Which Means We Also Need To Prepare For…

6 6 So What We Really Need Is… Class A capability for the majority (97%) of the fires we encounter AND… AR-AFFF capability for Ethanol fires

7 7 What We Will Cover Water Additives For Ethanol Developing A Plan Traditional Foam Delivery Systems Whats New In Foam Delivery Systems

8 8 Water Additives For Ethanol Definitions And Concentrates NFPA Accuracy Standards

9 9 Foam Concentrates - Water Additives Wetting Agents Class A Foam Class B Foam Concentrates –Protein & Film Forming Fluoroprotein (FFFP) –Aqueous Film Forming Foams (AFFF) –Alcohol Resistant-AFFF (AR-AFFF) Emulsifiers / Spill Response Agents Gels The only concentrate effective on Ethanol fires

10 10 Proportioning 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 11 Common 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

12 12 Do Not Mix Class A & B Concentrates Result of mixed concentrates (in strainer)

13 13 Water Additives For Ethanol Definitions And Concentrates NFPA Accuracy Standards

14 14 For proportioning rates equal or greater than 1%: –- 0% to + 30% or 1 percentage point, whichever is less ( ) For proportioning rates less than 1%: –- 0% to + 40% ( ) 6% 30%20%10%10%20% 30% 3% 1% % LeanRich Allowable Range: 6%:6.0 – 7.0% 3%: % 1%:1.0 – 1.3% 0.5%: 0.5 – 0.70% 0.2%: 0.2 – 0.28% NFPA 1901 Now Requires…

15 15 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 16 What Is The Cost Of Inaccuracy? Lets assume: –$20 per gallon for concentrate –5,000 gallons per minute flow rate –3% proportioning rate –10% inaccuracy rate

17 17 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

18 18 Lets 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 19 Now, The Cost Of Inaccuracy 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

20 20 What Is The True Cost Of Your System? $ Initial Cost + $ Ongoing Operational Costs $ True Total Cost

21 21 For Your Consideration Different Initial and Ongoing Operational Costs Different performance capabilities and limitations Equipped to consider the total picture

22 22 Developing A Plan NFPA 11 Application Rates Doing The Math

23 23 Application Rates A measure of foam solution, applied per unit of time, per unit of total area –Typically expressed as GPM/Sq Ft –Or, LPM/Sq Meter Not to be confused with proportioning rate –Expressed as % concentration

24 24 NFPA 11 Minimum Application Rates SPILL FIRES LOADING RACKS DIKED AREAS NON DIKED AREAS TANK FIRES FULL SURFACE SEAL AREA

30 30 Tank Fires – Full Surface (Type III) NFPA 11 – 2005 ( ) Minimum Application RatesGPM/SFLPM/SM Hydrocarbons Alcohol / Polar SolventsRefer To Listings Min Discharge Time Flash Point Above 100 F50 Min Flash Point Below 100 F65 Min Crude Petroleum65 Min

31 31 Tank Fires – Full Surface (Type III) Over 60 foot diameter - Recommended Minimum Application RatesGPM/SFLPM/SM Up To 150 Foot Diameter to 200 Foot Diameter to 250 Foot Diameter to 300 Foot Diameter Over 300 Foot Diameter

32 32 Tank Fires – Seal Area (Floating Type) NFPA 11 – 2005 ( ) Minimum Application RatesGPM/SFLPM/SM Top Of Seal Below Seal Min Discharge Time Top Of Seal20 Min Below Seal10 Min

33 33 NFPA 11 Standards Are Minimums Design To Succeed 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
