    Study Notes

    Miami-Dade Fire Rescue (MDFR) Vehicle Operations

    • MDFR employees are responsible for the safe driving, operation, inspection, testing, and maintenance of all assigned vehicles and equipment.
    • Classification of leakage:
      • Class 1: Seepage or discoloration without forming drops.
      • Class 2: Leakage forming drops but not falling off.
      • Class 3: Leakage that causes drops to fall.

    Diesel and Emission Systems

    • Diesel Exhaust Fluid (DEF) converts nitrogen oxides (NOx) into harmless nitrogen (N2) and water (H2O) through a SCR catalyst.
    • Diesel Particulate Filter (DPF) captures diesel soot emissions.

    Out-of-Service Criteria

    • Deficiencies that meet NFPA 1911 standards that require vehicles to be placed out of service include critical issues in various vehicle systems (e.g., engine, brakes, electrical).

    Daily Safety Guidelines

    • Always chock the wheels of parked fire rescue vehicles equipped with wheel chocks.
    • Engage the parking brake on all parked units, irrespective of the gradient.
    • Morning apparatus checks should include a backup observer and occur in a ventilated area.
    • Caution must be exercised when inspecting undercarriage components.

    Deficiency Notification

    • Defects include cracked windshields, missing mirrors, and Class 3 leaks in key systems (steering, axle, wheels).
    • Immediate consultation with the Support Office is necessary for certain defects that put vehicles out of service.

    Repair Requests

    • All repair requests should be submitted through the MEB Online Reporting System.
    • Routine repairs require online submission, while urgent issues must directly notify the Support Office.

    Responsibilities of Driver/Operator

    • Daily apparatus inspections must be completed and reported on serious defects immediately.
    • Ensure to log mileage and engine hours in MEB for proper maintenance scheduling.
    • Use the Daily Apparatus Inspection Report as a maintenance reference.

    Daily Inspection Requirements

    • Check body integrity, tire inflation, and tread depth.
    • Examine engine fluid levels, battery condition, and steering play.
    • Verify all electrical systems and emergency warning devices are operational.
    • Inspect braking systems for leaks and ensure functionality.

    Fire Pump and Aerial Equipment

    • Perform daily checks on fire pumps, including engaging with hydrants and ensuring all operational readings are accurate.
    • Regularly check operations and maintenance of aerial hydraulic systems according to manufacturer guidelines.

    Cleaning Procedures

    • Daily washing with appropriate truck wash solutions is mandatory, including specific cleaning practices to avoid damaging equipment.
    • The undercarriage must be cleaned weekly, while quarterly waxing is scheduled for different units to maintain vehicle condition.
