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 Checks and Recommended Procedures

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.
