    Study Notes

    Leak Classifications

    • Class 1 Leak: Wetness around the leak.
    • Class 2 Leak: Forms a drop but does not drip.
    • Class 3 Leak: Drops or puddle underneath the leak.

    Safety Responsibilities

    • Safety is the primary responsibility of the driver operator.
    • Motor vehicle accidents are the second leading cause of injuries and deaths in the fire service.

    Seatbelt and Spotter Usage

    • Seatbelts must be worn at all times except during patient care in the back of an ambulance.
    • A spotter is required whenever backing up.

    Driving Protocols

    • Always drive defensively, following state, local, and departmental regulations during both emergency and non-emergency situations.

    Apparatus Considerations

    • Apparatus positioning is crucial when assessing the scene.
    • CFR 49 regulates apparatus inspection; Parts 390 and 396 mandate maintenance.

    Inspections and Documentation

    • Detailed inspections of seats, seat belts, controls, windows, doors, and mirrors are necessary.
    • Proper paperwork is essential; if it’s not documented, it’s considered not to have happened.

    Out of Service Criteria

    • A cracked or broken windshield must obstruct the operator's view to put an apparatus out of service.
    • Defrosters being broken will also put an apparatus out of service.
    • Class 3 leaks would also result in service disqualification.

    Licensing and Driving Requirements

    • A Class B license permits driving vehicles over 26,000 lbs, buses (with endorsements), and farm labor vehicles (with endorsements).
    • The minimum license to operate fire department vehicles is a Class C with a firefighter endorsement.

    Emergency Vehicle Statutes

    • Code 3 authorization comes from the California Vehicle Code.
    • A single burning red warning lamp must be visible from 1,000 ft.

    Driving Regulations

    • Drivers must maintain a minimum distance of 300 ft when following emergency vehicles.
    • Passing a school bus with an extended stop sign is prohibited, even in emergency conditions.
    • Section 21055 covers exemptions for authorized emergency vehicles.

    Vehicle Maintenance Issues

    • Indicators of steering problems include front-end pulling, drifting, or difficulty steering.
    • Issues causing steering difficulties may include alignment issues, low tire pressure, or axle misalignment.
    • Visual inspections of radiators are necessary to check for leaks, damage, and coolant quality.

    Electrical Systems

    • Most fire apparatus operates on a 24-volt system.
    • Voltage is electrical pressure, while current, measured in amperes, is the rate of electron flow.
    • Resistance is the opposition to current flow.

    Brake System Maintenance

    • Most large modern apparatus employ air brakes.
    • Proper adjustment for belts allows up to 3/4 of an inch of play.
    • Safety relief valves in air brake systems prevent overpressure.

    Air Brake Specifications

    • The low air alarm activates between 55-75 psi.
    • Spring brakes engage at 20-45 psi.
    • Dual air brake systems enhance safety.
    • Daily testing of the air compressor and governor is essential.
    • Slack adjusters should have a maximum throw of two inches, and should be visually inspected for angle requirements during operation.

    General Maintenance and Inspection

    • Focus areas during inspections include auxiliary equipment like generators and pumps, brake components, and hydraulic systems.
    • Maintain accurate records for warranty claims and recurrent repairs.
