2.and 3. Apparatus Inspection And Maintenance Flashcards
Two types of inspections are actually conducted during a walk around inspection:
Operational readiness
Pre-trip roadworthiness
Page 36
Tire selection for Apparatus are based on:
Gross axle weight rating
Page 38
The weight of an empty fire apparatus fresh off the assembly line with no tools, water, equipment, or passengers.
Curb weight
Page 41
Maximum weight at which a vehicle can be safely operated on roadways in ideal conditions.
Gross vehicle weight rating (GVWR)

This system uses diesel exhaust fluid (DEF) to help further reduce emissions.
Selective Catalyst Reductant (SCR)
Page 45
DEF is stored in the tank downstream of the DPF and is injected into the fuel in order to reduce the_____ emissions from diesel engines.
Nitrogen Oxide (NOx)
Page 45
Most automotive batteries contain____ and _____acid. Batteries can also give off_____gas.
Lead and sulfuric acid
Hydrogen gas
Page 47
The driver should perform_____ inspections to ensure that all work has been properly completed in accordance with the manufacture guidelines
Post maintenance/repair inspection

Add windshield washer fluid if the tank is:
Less than half full
Page 65
Clean away any corrosion around terminals with a mixture of:
Baking soda and water
Page 65
Usually found on the driver has been found guilty of a gross violation of standing laws, policies, or ordinances.
Negligence
Page 84
Lights when the exhaust system is very hot, usually due to an active regeneration in process.
High exhaust system temperature (HEST)
Page 94
Angle formed by level ground and a line from the point where the rear tires touch the ground to the bottom of the frame at the wheel base mid point.
Breakover angle
Page 97
Occurs when the throttle is applied to a manual transmission into high gear for the demand on the engine.
Engine lugging
Page 99
The time needed to stop the Apparatus or perform and evasive maneuver at the current rate of speed.
Visual lead time

Two common types of skidding:
Acceleration skid
Locked wheel skid
Page 108
_____ and _____ provide the highest level of braking torque and are unaffected by transmission gear changes.
Transmission output retarders
Electromagnetic retarders
Page109
The least capable of the four auxiliary braking devices.
Exhaust brakes

In this condition, each axle receives full torch for the engine.
Interaxle differential lock
Page 111
Designed to help prevent rollovers and tipping caused by cornering or certain changes in direction.
Stability control systems
Page 112
Becomes active when the ABS computer senses an eminent rollover condition—even if the driver does not.
Rollover Stability Control (RSC)
_____ applies the brakes independently to aim the vehicle in the direction that the operator position the steering wheel.
Electronics Stability Control (ESC or ESP)
