    Study Notes

    D/E Manual - Chapter 1

    • PBCFR units respond to nearly 150,000 calls per year.
    • Approximately 20-25% of all firefighter injuries or fatalities are caused by vehicle collisions while responding to or returning from emergency calls.
    • Common causes include: excessive speed, improper navigation, lack of familiarity with equipment, lack of seatbelt use, and inadequate driver training.
    • Every PBCFR officer must adhere to Florida State Motor Vehicle Laws, ordinances, county regulations, and DOT regulations; violations can result in criminal and/or civil prosecution.
    • A reasonable and prudent individual performing similar duties would act similarly in analogous circumstances.
    • Factors considered when determining if the risk of emergency vehicle operation outweighs the potential risk to public safety include: type of call, type of roadway, weather conditions, and other operational factors.

    Emergency Vehicle Operations

    • Average weights of various emergency vehicles include:
      • Sutphen: 40,000 lbs
      • Aerial: 50,000 lbs
      • Tender: 57,000 lbs
      • Brush Truck: 28,000 lbs
    • Important factors for emergency vehicle operation include: weight transfer, reaction time, braking distance, and approach/departure angles.
    • Top-heavy vehicles are more prone to rollovers.

    Emergency Vehicle Operational Considerations

    • Headlights should always be on while the vehicle is in operation.
    • During nighttime operations, turn off the "wig-wag" function.
    • Speeding in excess of posted limits is permitted during emergencies if doing so doesn't endanger responders or the public. This is a last resort technique performed with extreme caution, only in dire situations.
    • Use sirens (wail or federal-Q) when responding to emergencies.
    • Maintain separation of at least 300-500 feet between two or more units traveling code 3.
    • Do not pass another emergency vehicle traveling code 3.
    • Keep vehicle cabin and compartment doors closed when not in use.
    • Night driving techniques include: adjusting dash/panel lights, maintaining appropriate speeds, keeping headlights and windshields clear, scanning the roadway.
    • In case of a tire blow-out, slow down, safely pull over to the side of the road, turn on hazard lights and ensure appropriate safety checks.
    • Appropriate safety gear such as safety vests and helmets must be worn at all times, especially at accident scenes. Never turn your back on traffic and always be aware of the surroundings.

    Chapter 2 - Water Supply

    • Adequate water supply is crucial for fire ground operations.
    • Water requirements vary by apparatus (engines, aerials, brush trucks, tenders, rescue pumpers).
    • Onboard water tanks will lose effectiveness if more than 200 gallons per minute are used.
    • Hydrants should be evaluated and noted for suitability as water sources.
    • Use of portable folding dump tanks at the scene of the incident is an alternative method for water supply to the fire scene.
    • Techniques such as "relay pumping" and "water shuttle operations" can provide adequate water source if onboard tanks run low.

    Chapter 3 - Hydrant Operations

    • Operational and non-operational hydrants are marked graphically to assist with operation.
    • Water pressure and volume of hydrants must be checked.
    • If hydrants are inoperative, alert necessary personnel.
    • Hydrant maintenance to ensure safe operation and functional use is crucial.

    Chapter 4 - Water Supply and Operation

    • Relay pumping is a preferred method of water supply, especially in rural areas.
    • Water shuttle operations can be an alternative when relay pumping isn't suitable.
    • Effective water management during emergencies is critical.

    Chapter 5 - Attack Engine Operations

    • Attack vehicles keep water reservoirs full, in case tenders run out of water during emergencies.
    • The optimal method of water delivery is direct pumping, in this case, two pieces of equipment working together with a single 3 inch supply line.
    • Alternate tactics include “Modified Direct Pumping” and “Folding Dump Tank Operations”.
    • Dump tank sites selection, filling sites, and routing must all be planned and implemented to ensure a smooth and effective water transfer system.

    Chapter 6 - Nozzle Operation

    • Automatic nozzles, variable flow nozzles, and master stream nozzles are used for efficient use of water.
    • Flow rate and pressure for each type of nozzle are set.
    • Proper nozzle maintenance is key to operation.
    • Techniques used to ensure safe and effective operation of nozzles is crucial.
