10 Questions

  1. What is one traffic law that responding fire apparatus generally cannot disregard?
    1. Stopping for a schoolbus
    2. Passing a stop sign without coming to a complete stop
    3. Proceeding past a red light without coming to a complete stop
    4. Blocking traffic on a limited-access highway
  2. What is generally considered the safest position for an apparatus, relative to a building, should a collapse occur?
    1. Along either crosswind side
    2. Behind the building (side 3)
    3. Directly in front of the main entrance
    4. At any corner
  3. When a pumper and an aerial are operating beside each other in front of a building, what is the rule of thumb for which one should be on the inside (closer to the building)?
    1. Pumper on outside if aerial has its own pump
    2. Pumper on inside if immediate aerial rescue operations are anticipated
    3. Pumper on outside if two or more stories are involved
    4. Pumper on inside if building is five stories or less
  4. What is a pipe called that is set up at a drafting site extending from under the water to above ground to facilitate hookup?
    1. A dry standpipe
    2. A cistern
    3. A dry hydrant
    4. A LaPlace valve
  5. What is the point of attaching gated valves to the smaller discharges of a hydrant when making the large diameter hookup?
    1. It allows rapid shutdown of the hydrant in the event of a burst hose
    2. It allows connections to later be made to the smaller discharges without interruption of the original water supply
    3. It allows the bleeding off of pressure in the event that excessive pump pressure developed, without shutting down any attack lines
    4. It allows a degree of fine-tuning the discharge pressure to an extent not available otherwise
  6. People often confuse dual and tandem pumping. What is dual pumping?
    1. Two strong pumpers charge the hydrant system by discharging into it while supplied by draft
    2. One strong hydrant supplies two pumpers
    3. One strong pumper supplies another weaker pumper
    4. One pumper is supplied by two independently-mained hydrants
  7. How much does fresh water weigh, in pounds per cubic foot?
    1. 98.6
    2. 62.5
    3. 14.7
    4. 8.3
  8. What is the practical significance of the latent heat of vaporization to firefighting?
    1. Boiling water uses up a whole lot of heat
    2. Firefighters can never be burned if steam is present
    3. Firefighters can only be burned if steam is present
    4. If the water from the hoseline turns to steam before hitting the fuel, it is useless for absorbing any of the heat of the fire
  9. What does it mean if a fluid has a specific gravity of less than one?
    1. It absorbs less heat than water
    2. It flows more easily than water
    3. It is less volatile than water
    4. It is lighter than water
  10. One disadvantage of water as an extinguishing agent is that it has a high surface tension. What does that mean in practical terms?
    1. It is abrasive to pumps and hoses
    2. It resists soaking into dense materials
    3. It tends to float on other liquids
    4. It tends to bead up rather than flow
