Study Notes

Driver/Operator Flashcards Key Points

  • Blind Spot: Located on the right side of the engine.
  • Driving Style: Should be defensive to ensure safety.
  • Transmission Issue: Lack of fluid can cause non-engagement.
  • Low Air Warning: Activates at 60 PSI or at half of cut-out pressure.
  • Electricity in Fire Apparatus: Uses Direct Current (DC).
  • Hydraulic Brake Test: Brake pedal should not move after being pumped three times and held for five seconds.
  • Tire Tread Wear: Excessive wear in the center indicates overinflation.
  • Voltage Synonym: Also referred to as electrical current.
  • Auxiliary Heat Exchanger: Part of the engine's cooling system.
  • Slack Adjusters: Angle between push rod and adjuster must not be less than 90 degrees when brakes are applied.
  • Exhaust Noise: Gradual increase indicates a failing exhaust manifold gasket.
  • NFPA 1911: Provides guidelines for when to place fire apparatus out of service due to fluid leaks.
  • Disk Brakes: Function similarly to a large C-clamp.
  • Air Brake Types: Include parking brake, emergency brake, and service brake.
  • Testing Brake Lights: Use a test light if the lights do not activate.
  • Leakage Class 2: Fluid leakage that forms drops but does not cause them to fall.
  • Draining Reservoir: First step when air compressor cycles too frequently due to decreased reservoir volume.
  • Current Definition: Measured in amperes, representing the flow of electrons.
  • Oil Pressure Drop: A sudden drop with loud noise may indicate a broken connecting rod.
  • Transmission Overfill: Can lead to over-pressurization and broken seals.
  • Tread Depth Requirements: Minimum of 4/32 inch for front tires and 2/32 inch for non-steering wheels.
  • Slack Adjusters Repairs: Only certified air brake technicians are authorized to repair.
  • Damaged Seatbelt Protocol: Move passenger to a non-damaged seat or take the vehicle out of service if no other seats are available.

  • Traffic Accidents: Second leading cause of firefighter on-duty deaths.
  • Brake Testing Standards: New apparatus must stop within 35 feet at 20 MPH.
  • Emergency Vehicle Distance: Minimum distance from a vehicle to an emergency vehicle is 300-500 feet.
  • Backing Precautions: Drivers/operators should avoid backing whenever possible.
  • Emergency Vehicle Sirens: Designed to project audible warning 300 feet at 40 MPH and 12 feet at 60 MPH.
  • Steering Wheel Position: Ideal hand position is at opposite sides.
  • School Bus Stop Protocol: Passing allowed on a double-yellow line when traveling in the opposite direction.
  • Authority for Code Three Operation: Comes from California Vehicle Code (CVC).
  • Driver Attention Distance: Look ahead 1/4 mile at highway speeds and 1/2 mile in city driving.
  • Leakage Class Definitions: Class 1 (wetness), Class 2 (drops form but don't fall), Class 3 (drops falling).
  • Spring Brakes: Meet both emergency and parking brake requirements.
  • Safety Relief Valve Activation: Operates at 150 PSI, not at lower pressures.
  • Out of Service Evaluation: Required for air compressor failure to maintain 80-90 PSI under idle conditions.
  • Defroster Issues: If defective, the apparatus should be taken out of service.
  • Seat Belt Protocol: Torn passenger seat belts do not necessarily require out-of-service status under NFPA.
  • Air Pressure Protection Valves: Prevents operation of air horns below 80 PSI.
  • Corrosion in Batteries: Considered the worst condition for battery performance.
  • Milky White Coolant: Indicates the presence of oil in the coolant system.
  • Electrical Pressure: Defined as voltage, analogous to PSI in hydraulic systems.
  • Resistance Definitions: Opposition to current flow, similar to friction loss.
  • Ohm's Law: Describes the relationship between current, voltage, and resistance.
  • Alternating Current: Changes amplitude and polarity regularly.
  • Starter Engagement Steps: Involves a two-step process to activate the solenoid and starter motor.
  • Air Brake System Sequence: Includes compressor, governor, dryer, safety valve, check valve, and storage tanks.
  • Safety Relief Valve Pressure: Activated at 150 PSI.
