Study Notes
Vehicle Movement and Control
- Key to all vehicle movement: Steering, Braking, Accelerating, Condition, and Inflation
- Tire components: Tread, Shoulder, Inner Plies, Sidewall, and Bead
Tires - Condition
- No cuts that expose cords
- No bulges on the sidewall indicating cord separation
- Front tires are not re-grooved or recapped
- Front tires are not mismatched
Tires - Inflation
- Improper inflation increases stress on the tire
- Improper inflation reduces performance in emergency handling
- Improper inflation increases wear and resistance to rolling, creating heat
- Check for obvious flatness, leaks, and abnormal bulging
- Measure tire pressure against manufacturer's recommendations
Tires - Depth
- Insufficient tread depth increases stopping distance
- Insufficient tread depth reduces steering performance
- Insufficient tread depth fails to channel rain and snow from beneath the tread, leading to hydroplaning
- DOT minimum tread depths: 4/32 inch for steering axles and 2/32 inch for other axles
- Check tread depth in multiple areas and grooves
Tires - Depth Measurement
- Use a quarter to measure tread depth on steering axles (George Washington's head should be below the tread surface)
- Use a penny to measure tread depth on non-steering axles (Abraham Lincoln's head should be below the tread surface)
Other Considerations
- Steering tires: Check tread patterns match from side to side, and they are the same size and type
Pre-trip Inspections
- Identify major vehicle systems and their component parts
- Determine methods and requirements for pre-trip inspection of vehicle systems
- Define maintenance requirements for vehicle systems
Objectives
- Identify major vehicle systems and their component parts
- Determine methods and requirements for pre-trip inspection of vehicle systems
- Define maintenance requirements for vehicle systems
- Review MCFRS out-of-service criteria for fire department apparatus
- Review defect reporting and resources for apparatus operators
Motivation
- Correctly identify defects and write accurate defect reports
- Determine and differentiate between normal, monitoring, and out-of-service conditions
- Identify critical safety issues before they cause injury or damage
Definitions
- Leakage: Class 1 (seepage), Class 2 (leakage forming drops), Class 3 (leakage with dripping drops)
- Operational Test: A test to determine the operational readiness of a component on a fire apparatus
