1

What is the NFPA standard for driver qualifications?

NFPA 1002.

2

What is the difference between maintenance and repair, concerning apparatus?

Maintenance means keeping apparatus in a ready state.
Repair means to restore/replace parts on a component which have become inoperable.

3

What does preventive maintenance do?

-ensures apparatus reliability
-reduces frequency of repairs
-lessons out-of-service time

4

What is the purpose of preventive maintenance?

To try to eliminate catastrophic failures that could threaten life.

5

What program identifies which maintenance functions are to be performed, and who performs them?

Standard Operating Procedures (SOP's).

6

Why are maintenance and inspection records important?

-in a warranty claim, records may be needed
-in accidents, investigators may view maintenance records
-lawsuit involving apparatus accident, records may be subpoenaed

7

What are the main reasons for keeping the apparatus clean, from the ff standpoint and from the public standpoint?

FF- permits proper inspection, ensures good operation, clean body promotes longer vehicle life
Public- dirty truck may be seen as an abuse of taxpayer money

8

How should a new apparatus be washed?

New apparatus should be washed with cold water for the first 6 months to harden the paint.

9

When can wax be used on a new apparatus?

After 6 months.

10

How should the apparatus inspection process be?

It should be a systematic method (ensures all things are checked).

11

As the driver/operator performs the daily walk-around inspection, what 2 types of inspections are being conducted simultaneously?

-commercial vehicle pre-trip
-inspection for equipment attached to the apparatus

12

One method of performing a pre-trip inspection is the "Walk-Around" method. How is this conducted?

-start at drivers door
-begin inspecting in a clockwise rotation
-final step, enter cab, start engine, perform functional test

13

What is checked during tire inspection?

-tire type
-tire condition
-tire inflation

14

What is curb weight of an apparatus?

Weight of an empty apparatus, fresh off the assembly line (no tools/water).

15

What is Gross Volume Weight Rating of an apparatus?

The max weight AT WHICH A VEHICLE CAN BE OPERATED.

16

What is "Free Play", concerning the steering wheel of the apparatus?

It refers to the amount of steering wheel movement, that does not result in apparatus movement of the front wheels (should be no more than 10 degrees in either direction).

17

The speedometer of the apparatus should be at zero when parked. If it is above or below zero, what 2 possibilities could exist?

-gauge is defective
-apparatus in PUMP instead of DRIVE

18

Newer apparatus may have electrical load management systems, to prevent electrical overload. The systems have a load sequencer and a load monitor, what does each do?

Load sequencer- turns various lights on at different intervals
Load monitor- "watches" the system for added electrical load (if that happens, system will "load shed")

19

What is "Free Play", concerning the clutch on a manual transmission apparatus?

Free Play is the distance the pedal must be pushed before clutch releases.

20

What are the 2 most important safety inspections a driver will perform daily?

-make sure apparatus has no compromise to steering
-make sure apparatus will stop

21

Apparatus with air brakes have an air pressure protection valve. What does this valve do?

It prevents air horns and other peripherals from being operated, if the pressure in the air reservoir falls below 80 psi.

22

What does the ABS braking system do?

Reduces the possibility of going into a slide/spin during heavy braking (does not stop faster, but greatly enhances a controlled stop).

23

At a minimum, when should apparatus brakes be thoroughly tested?

At least once per year (per NFPA ).

24

The parking brake must hold the apparatus in place on how steep of an incline?

20 percent grade.

25

How often should the cab of an apparatus be lifted for inspection?

At least weekly for full inspection.

26

What are the 2 reasons for an operational check of the aerial device?

-ensure aerial device is working properly
-review of aerial device operation for the driver/operator.

27

When is a new apparatus tested?

-immediately after construction (pre-service test)
-once in service, at least yearly (service test)

28

What is load testing?

Used to determine if apparatus can safely handle the amount of weight its rated for.

29

What is non-destructive testing?

testing methods used to inspect structural components without altering/damaging components.

30

What is operational testing?

Tests used to determine if the hydraulic system is functioning correctly.
