Answer 7

Speed limits, direction of travel, direction of turns, parking statutes and ordinances

Question 8

Who is responsible if the d/o is negligent?

Answer 8

The d/o and the jurisdiction they represent

Question 9

What are the drawbacks to a collision for the fire department?

Answer 9

Delay of responders until new are deployed, reduced capacity until app can be replaced, cost litigation, financial burden

Question 10

Where is the most common place for a collision?

Answer 10

Intersection

Question 11

What can a d/o do to lower the chances of a collision?

Answer 11

Be familiar with app, roads, local traffic laws, practice/training in the area

Question 12

What are the 7 causes of a collision?

Answer 12

Improper backing, reckless driving, excessive speed, lack of driving skill and experience, overloading and misuse, mech failure, d/o readiness

Question 13

What is brake fade? How does it occur?

Answer 13

Loss of braking due to excessive use of brakes. Excessive braking causes them to heat and expand, creating wear.

Question 14

How do you help prevent mechanical failure of an apparatus?

Answer 14

Pretrip inspection

Question 15

How do you prevent poor vehicle design?

Answer 15

Have them made by a manufacturer. “Homebuilt” app made by the fire depo often have design probs.

Question 16

Examples of driver impairment

Answer 16

Substance abuse, illness, depression, fatigue

Question 17

Loading fire hose while in motion is common when loading what diameter of hose?

Answer 17

Large diameter 100mm or larger supply hose.

Question 18

Why shouldn’t you over idle a Diesel engine?

Answer 18

Wastes fuel, causes a buildup of carbon in valves and pistons.

Question 19

DPF

Answer 19

Burns particulates fully. Helps emit cleaner emissions.

Question 20

What happens when the DEF tank isn’t full?

Answer 20

Reduces torque output, harms engine, reduces speed

Question 21

Torque

Answer 21

Creates a rotational motion, helps increase speed

Question 22

How long should you let an engine cool before turning it off?

Answer 22

3-5 minutes

Question 23

Lugging

Answer 23

When throttle is applied when manual transmission is in too high a gear for rpm on engine

Question 24

Overthrottling

Answer 24

Injecting Diesel engine with too much fuel- can’t be burnt fast enough.

Question 25

Nfpa 1901

Answer 25

Standard for auto fire app

Question 26

Sirens

Answer 26

Off on limited access highways

Question 27

At what speed do apps outrun audible device range?

Answer 27

50mph

Question 28

Strobe light activated preemption devices

Answer 28

Strobe lights on app used to activate sensors in traffic lights

Question 29

Traffic signal preemption devices

Answer 29

Traffic control systems activated by siren

Question 30

GPS based traffic signal preemption devices

Answer 30

Uses gps to transmit data to a radio receiver on traffic light

Question 31

Nfpa 1500

Answer 31

Safety

Question 32

Skidding

Answer 32

Excessive or abrupt braking

Question 33

Visual lead time

Answer 33

Scan ahead

Question 34

Braking distance

Answer 34

Distance travelled from time of pushing brakes to actual stop of vehicle

Question 35

Total stopping distance

Answer 35

Combo of drivers reaction distance and vehicle braking distance

Question 36

Reaction distance

Answer 36

Distance travelled from when driver moves foot from gas to brake

Question 37

Acceleration skid

Answer 37

Gas pedal applied too quickly- lose traction- ease off acc, straighten front wheels

Question 38

Locked wheel skid

Answer 38

Braking too hard at a high rate of speed, locking the wheels. Doesn’t matter which way the wheel is turned. Slow and straighten front wheels

Question 39

ABS

Answer 39

Minimize skidding. Computer that monitors each wheel and controls pressure to brakes. Sensing device sends speed of tires to computer. When wheel begins to lock- computer compares to other to see if it should be turning. It reduces brake pressure and allows wheel to turn and then brakes again.

Question 40

Aux braking systems

Answer 40

Reduces brake fade, and service brake maintenance costs. 4 types- ehxhaist brake, engine compression brake, transmission output retarder, electromagnetic retarder

Question 41

Exhaust brakes

Answer 41

Least capable. Uses valve to restrict flow of exhaust, creating back pressure for braking

Question 42

Engine compression brakes

Answer 42

Converts mech energy into heat by compressing engine intake and creating exhaust.

Question 43

Electromagnetic retarders

Answer 43

On driveline or rear axle.electromagnetic field made by supplying electrical power to coils in retarder. Inhibits rotation of rotor and creates braking torque.

Question 44

Transmission retarders

Answer 44

Viscous property of auto transmission fluid to retard driveline. Trans fluid put into retarder and energy is is absorbed into fluid. Affects rear wheels and adds heat to trans fluid.

Question 45

Auto traction control (atc)

Answer 45

Reduces engine torque and applies it to wheels that still have traction.

Question 46

Driver controlled differential lock

Answer 46

Forces both wheels to turn at same speed resulting in a lock of the differential to maximize traction

Question 47

Inter axle differential lock

Answer 47

Allows speed diffs in the rear driving axles. Creates one solid driveline to get full torque from engine.

Question 48

Roll Stability control

Answer 48

Reads accelerator and senses rollover. Computer slows app by reducing engine torque. May apply service brakes to wheels

Question 49

Electronic stability control

Answer 49

Applies brakes independently to aim app in direction of steering (steering wheel sensor)

Question 50

Stability system safety

Answer 50

Helps with stability around corners and changes in direction

Question 51

Tillering

Answer 51

Tight turns and maneuvers. Tiller axle- allows tillers of tractor trailer app to maneuver through tight traffic.

Question 52

Intake/discharge caps

Answer 52

Never remove a cap for a pressurized pump. Open bleeder or drain valve.
