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
