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.

Unit Officer Responsibilities

Unit Officers must ensure compliance with all operational procedures and maintenance protocols.
