1

Fire apparatus driver/operators are responsible for __________, _______, and _____ to and from the scene of an incident.

>The safe transport of firefighters, apparatus, and equipment

2

If the driver/operator is neligent in the operation of an emergency vehicle and is involved in a collision, both the ________ and the _________ may be held responsible.

Driver/Operator
Jurisdiction he or she represents

3

______ is usually found when the driver/operator has been found guilty of a gross violation of standing laws, policies, or ordinances.

Negligence

4

A fire apparatus driver/operator should maintain ___________ in order to lower the chances of being involved in a collision with an object, pedestrian, or other vehicle.

Situational Awareness

5

In general, fire apparatus collision are grouped into seven basic causes, which reflect the lack of due regard and situational awareness.

1) Improper Backing
2) Reckless Driving
3) Excessive Speed
4) Lack of driving skill and experience
5) Overloading and misuse
6) Mechanical Failure
7) Driver/Operator personal readiness

6

In ___ percent of all collisions, the driver/operator was not aware of a problem until it was too late to correct.

42%

7

After a driver/operator continues to ignore an empty DEF tank, the apparatus may be limited in speed to __ mph and will need service from the dealer.

5 mph

8

Shutting down an engine without sufficient cool down may result in the following:

>Immediate increase of engine temperature from lack of coolant circulation
>Oil film "burning" on hot surfaces
>Damage to heads and exhaust manifolds
>Damage to the turbocharger that can result in seizure

9

Angle formed by level ground and a line from the point where the front tires touch the ground to the lowest projection at the front of the apparatus.

Angle of Approach

10

Angle formed by level ground and a line from the point where the rear tires touch the ground to the lowest projection at the rear of the apparatus

Angle of Departure

11

Angle formed by level ground and a line from the point where the rear tires touch the ground to the bottom on the frame at the wheelbase midpoint

Breakover Angle

12

Poor weight distribution can make a vehicle handling unsafe, such as the following:

>Too much weight on the steering axle can cause hard steering and can damage the steering axle and tires
>Under-loaded front axles can make the steering axle weight too light to steer safely
>Too little weight on the driving axles can cause poor traction
>The drive wheels may spin easily.

13

It may take __ to __ times greater distance for a vehicle to come to a complete stop on snow and ice than it does on dry pavement.

3 to 15

14

At speeds about __ mph, and emergency vehicle may outrun the effective range of its audible warning devices.

50 mph

15

In some instances, increasing the speed of an apparatus by __ can decrease the audible distance by ___ feet or more.

20 mph
250 feet

16

When more than one emergency vehicle is responding along the same route, they should travel at least ___ to ___ feet apart.

300 to 500 feet

17

The time needed to stop the apparatus or perform evasive maneuver at the current rate of speed is ________.

Visual Lead Time

18

The ___________ is the distance the vehicle travels from the time the brakes are applied until the apparatus comes to a complete stop.

Braking Distance

19

The ____________ is the sum of the driver/operator's reaction distance and the vehicle's braking distance.

Total Stopping Distance

20

___________ is the distance the apparatus travels while the driver/operator transfers his or her foot from the accelerator to the brake pedal.

Reaction Distance.

21

Some of the most common causes involving driver error include the following:

>Driving too fast for road conditions
>Failing to anticipate obstacles
>Improper use of auxiliary braking devices
>Improper maintenance of tire air pressure and adequate tread depth

22

NFPA 1901 requires that all apparatus with a GVWR of _____ lb or greater be equipped with an auxiliary braking system.

36,000 lb

23

There are four types of auxiliary brakes to aid the foundation brakes in slowing the vehicle.

>Exhaust Brake
>Engine Compression Brake
>Transmission Outer Retarder
>Electromagnetic Retarder

24

Considerations when using Aerial Apparatus Hose Chutes:

>Lay couplings so that they are pulled out straight, without flipping around.
>Lay hose so that it never crosses over itself when paying out.
>Maintain vehicle speed of 5 mph or less. At 5 mph, 7 feet of hose is pulled out each second.
