1 Ethanol Tank Fire Fighting

2 Goal of ETANKFIRE project Ensure proper investments in fire protection of ethanol storage plants Determine the large scale fire behaviour of ethanol fuels Provide input to computer models for risk assessment Develop and validate a methodology for fire fighting of tank fires containing ethanol fuels Provide knowledge to be used in recommendations and standards Input to fire fighter training

3 Proposed structure of ETANKFIRE project WP1 Litterature Review and Standard Scale Tests WP0 Management WP2 Small Scale Tank Fire Tests WP3 Medium Scale Tank Fire Tests 2222 WP5 Heat Radiation and Burning Rate Tests WP4 Large Scale Tank Fire Tests WP6 Dissemination

4 WP1 Litterature review and Standard Scale Tests with Foam Goal: To provide information for design of WP2 test programme Litterature review of existing test data and update of experience from real fires Test scale 1,73-4,5 m 2 Reference tests according to standard foam test procedures with various ethanol fuels Tests with increased preburn time (10-30 min) Tests with increased fuel depth

5 WP2 Small Scale Tank Fire Tests Goal: To evaluate various extinguishing techniques to be used in WP3 test programme Small scale tank, area 1,73-4,5 m 2 Fuel depth should ensure limited dilution effect Tests with various foam application methods Tests with non-conventional techniques

6 Questions for WP2 Could a traditional foam attack using monitors be successful? Type of application (swirling technique, etc) Application rate Duration - foam stock requirements Could alternative foam application techniques / foam types provide better performance? Medium expansion foam, CAFS, etc

7 Foam application technique by hydraulic platform Low expansion Medium expansion (High expansion?)

8 Questions for WP2 How should fixed systems be designed Conventional over-top system Linear foam nozzle application Semi sub-surface

9 FoamFatale foam system (a type of CAFS with a linear foam nozzle) Video demo

10 FoamFatale foam system (a type of CAFS with a linear foam nozzle) Video demo

11 FoamFatale foam system (a type of CAFS with a linear foam nozzle) Video demo

12 Questions for WP2 Could non-conventional techniques be a solution? Liquid nitrogen Solid foam (foam glass, glass/polymeric spheres, )

19 Non-conventional-Foam glass application Reduce fire intensity dramatically but don t extinguish. Application technique to be developed Ref: SP Report 2010:40

21 Advantages solid foam Could be used as a passive protection in bunds and storage tanks (combined or instead of internal floating roof) Application technique need to be developed for use as fire fighting media No or reduced contamination of fuel and no environmental impact Fuel surface is secured during tank discharge operation More knowledge needed to develop design rules

22 WP3-4 Medium and Large Scale Tank Fire Tests Goal: To evaluate some selected extinguishing techniques in medium and large/full scale tank fire tests Medium scale tank, area m 2 (Dia 6-7 m) Large/full scale tank, area m 2 (Dia m)

23 WP3-4 Medium and Large Scale Tank Fire Tests

24 WP5 Burning behaviour of ethanol Goal: To determine heat radiation, burning rate and flame height from a large scale ethanol fire. Pool fire tests, m 2 (Dia m) E95, E50, Heat radiation measurements at various distances Burning rate of fuel Flame height Exposure of objects

25 WP5 Burning behaviour of ethanol

26 WP5 Burning behaviour of ethanol

27 WP6 Dissemination Goal: To disseminate the results of the project Guidelines Input to standards and regulations (ISO, EN, NFPA, etc.) Input to improved risk assessment models Training material (EERC is a good model) Reports, conference papers, workshops,..

28 WP0 Management Goal: Effective project coordination and communication with funding organisations and companies SP project leaders Coordinated by SP and RPI under guidance of SC RPI will chair Steering Committee (SC) Reference Group (RG) will be invited (advisory only) Consortium Agreement between ETANKFIRE Partners and SP
