  1. UL/NIST StudiesTactical Findings Implementation into Zone 1 Tactical Considerations and Best Practices

  2. Four Key Concepts • Initial Size up • Fire Attack Considerations • Controlling the Flow Path • Ventilation

  3. Key Concepts Initial Size Up of the Structure

  4. Initial Size Up of the Structure The first arriving unit must perform a size up that will address the following: • Determine the location of the fire • Conduct a 360 • Identify basement, exterior fire • Stress the use of the TIC during size up. • Announce location of fire to in coming units.

  5. Initial Size Up of the Structure • Identify the flow path • Ventilation • Limited • Single Opening • Bi-Directional

  6. Initial Size Up of the Structure • Rescue • Determination of immediate rescue. • Fire extinguishment may be warranted before rescue is started.

  7. Initial Size Up of the Structure • Cooling the space/Extinguishment From Best Practices: Water should be applied to the fire as soon as possible from the safest location to reduce the heat release rates from burning materials. Any limited-duration water stream applied from the exterior should be immediately followed by an aggressive interior attack of any remaining fire.

  8. Key Concepts Fire Attack Considerations

  9. From Best Practices: While front door tactics provide quick access to most areas of the structure, water applied from the safest area – interior or exterior – will result in the fastest way to improve interior conditions for both occupants and fire control • Front Door • Exterior/Front Door • Front Door/Exterior

  10. Fire Attack Considerations • Why hit it from outside? • Cool the space. • Reduces flashover. • Interior application delayed. • Solid or straight stream directed at the ceiling to create large water droplets. An exterior attack is Offensive Mode if you remain forward moving

  11. Fire Attack Considerations • Water application to cool hot smoke • Reduce flashover

  13. Key Concepts Controlling the Flow Path

  14. Controlling the Flow Path • Opening doors and or windows is venting • Smoke and heat will travel to low pressure- an opening to the outside • Ventilation to flashover timeline.

  16. Key Concepts Ventilation

  17. Ventilation • Coordination of fire attack and ventilation • Ventilation too early will promote rapid buildup of fire • Venting is not cooling. • Ventilating and water application is cooling. • Requires Communication between fire attack and ventilation crews

  18. Implementation • Pre Assignment: Lesson from UL Learnshare- http://content.learnshare.com/courses/73/456883/story.html • PowerPointand discussion/lecture by Operations Battalion Chiefs. • Tabletop Applications: Tactical Training Program. • Hands on training: EMTG Live Fire Training November and December 2014 • Review the use of the concepts at each PIA.

  19. Other On-Line Resources • http://www.fireengineering.com/articles/2014/01/ventilation-limited-fire-keeping-it-rich-and-other-tactics-based-off-science.html Good article about ventilation and tactics • https://www.youtube.com/watch?v=82OJqcftNVg Great three-part series on flow path, in 1-hour segments
