  1. What is Pyrolysis?
    -Decomposition of a material brought about by heat in the absence of oxygen
  2. What is Mushrooming?
    Process in which rising smoke, heat, and gases encounter a horizontal barrier, and begin to move out and back down
  3. Define risk as stated in SOP 6-2
    The degree of potential harm from a particular hazard. Risk reflects both the likelihood that harm will occur and its degree of severity
  4. Foam application techniques
    • -Roll on
    • -bank-down
    • -rain down
  5. What are the six principles of pressure?
  6. Define the rain-down method for foam
    The rain down method directs the stream into the air above the fire or spill and allows the foam to float gently onto the surface of the fuel. Primarily used for above ground storage tanks, and when roll on or bank down are not feasible.
  7. What are the 4 ways foam works?
    • 1. Separating- Creates a barrier between the fuel and the fire
    • 2. Cooling- Lowers the temp of the fuel and adjacent surfaces
    • 3. Suppressing(Smothering)- Prevents the release of flammable vapors
    • 4. ????? Excludes OXYGEN???
    • IFSTA pg 357
  8. PDP for preconnect @ 200gpm and 150gpm

    • -Safe arrival is first priority.
    • -Take on repairs that are within their scope of authority
    • -Warning devices only request the right-of-way; they do not ensure the right-of-way
    • -The posted advisory speed for a curve shall be considered the maximum allowable speed under all conditions, regardless of response condition.
    • -When approaching a controlled intersection (traffic lights or stop signs) in an opposing traffic lane or center turn lane, the emergency vehicle shall come to a full stop before entering the intersection, even if the traffic light is green in the direction of travel.

    • -District operated water tenders and ladder trucks shall not exceed the posted speed limits at any time
    • -Tenders shall only respond in the non-priority mode.
  11. How do you proceed through intersections?
    • -Emergency vehicle drivers should always be prepared to stop
    • -Emergency vehicles shall come to a complete stop before entering intersection situations where normal driving would require a complete stop; i.e., red light
    • -The driver shall stop the vehicle, as necessary, to ensure that each lane may be crossed safely
  12. What changes velocity in a centrifigul pump?
    The speed of rotation of the impeller
  13. Describe vertical ventilation
  14. Describe chimney effect (ventilation and wildland)
  15. What are 4 different ways of proportioning foam foam? and 3 ways of storing foam?
    • Proportioning-
    • -Induction
    • -Injection
    • -Batch Mixing
    • -Premixing
    • Storing-
    • -Pails
    • -Barrels(Drums)
    • -Apparatus Tanks

    • -Firefighters may risk injury in a calculated manner to save a life that is likely to be savable
    • -Firefighters may assume moderate risk to save property that is likely to be savable and is of measurable value.
    • -Firefighters will risk nothing to save lives that have already been lost or for property that has already been destroyed.
