6 months

15

Method involves starting at the drivers door on the cab and working around the apparatus in a clockwise pattern.

Circle or Walk Around method.

16

What is the final step when using the circle/walk around method?

Getting in the cab, starting the apparatus, and perfuming a function check on apparatus systems.

17

What is another name for driver side and officer side?

Street side. Curb side.

18

When trails of fluid are left.

19

What three things should be checked on tires?

Proper tire inflation. Valve stem condition. Tire condition.

20

How should a extension cord on a cord reel be inspected.

By removing it and wiping it down with a damp cloth while looking for damage.

21

Covers everything from the rear of the cab to the tailboard on each side of the apparatus.

Left and Right Rear side inspections.

22

When are the hose loads of the main hose bed inspected?

During the rear inspection.

23

What position should all electrical switches be in when starting the apparatus and why?

Off, to avoid excessive load on the battery.

24

What may be the problem is a speedometer is not at or near 0 when parked?

Gauge is defective. The apparatus is in pump gear and not drive gear.

25

What is the general rule for how full a gas tank should be at all times?

3/4

26

At what decibel level should hearing protection be worn if you are going to be exposed to loud noises?

above 90 decibles

27

Incorporate a load sequencer and a load manager in the same device. Intended to prevent an overload of the apparatus electrical generation system.

Electrical Load Management System

28

Turns various lights on at specific intervals so that the start up electrical load for all devices does not occur at the same time.

Load Sequencer

29

Watches system for added electrical loads that threaten to overload the system. Will shut down less important electrical devices to prevent a overload.

Load Monitor.

30

When a load monitor shuts down less important electrical devices to prevent a overload.

Load Shedding.

31

The distance that the pedal must be pushed before the throw out bearing actually contacts the clutch release fingers. Also called free travel.

Free Play

32

What three things will insufficient free play cause?

Clutch to slip. Overheat. Wear out sooner than necessary.

33

What are three things that excessive free play will cause?

Clutch not releasing completely = Harsh shifting. Gear Clashes. Damage to gear teeth.

34

Steering wheels should not have more then how many degrees of free play in each direction?

10 degrees.

35

NFPA 1901 requires that a new apparatus be brought to a complete stop from a speed of ............mph, in a distance to not exceed................?

20 mph. 35'.

36

NFPA 1901 require a apparatus parking brake to hold a apparatus at what grade?

20%

37

Road brakes should be tested by driving forward at .......mph, applying the brakes. The apparatus should stop within ..............?

5 mph. 20'.

38

What three conditions would require a mechanic check a apparatus braking system?

Apparatus pulls to one side when brakes are applied. Brake pedal feels mushy. Does not stop withing 20' when being tested.

39

How is a apparatus parking brake tested?

Forward 5 mph. Pull parking brake. Stop within 20'.

40

Along with coolant level and hose condition what should be checked when inspecting the radiator?

That the radiator is not being blocked with trash or leaves.

41

When is it recommended that windshield washer be added?

When the level falls below half.

42

It may be necessary to check what fluid level after the apparatus has been driven in all forward gears and is running?

Transmission fluid level.

43

Some manufacturers recommend checking this fluid level while the engine is running at normal operating temps.

Power Steering fluid

44

If a apparatus air break system does not have automatic drains what should be done upon inspecting the brake system?

Drain off any accumulated condensation.

45

What four things determine effective lubrication?

Use of proper grade of recommended lubrication. Frequency. Amount used. Method of lubrication.

46

To select the proper lubrication consider these three things.

Requirements of the unit to be lubricated. Characteristics of the lubrication. Manufacturers recommendation.

47

At what other times should a apparatus inspection take place other then the pre-trip inspection?

After a long drive. After operating at a fire scene for a extended period of time.

48

A black/negative battery charger cable should be attached where on the apparatus?

To the apparatus frame.

49

What are the steps for hooking up and taking off a battery charger.

Red to positive battery terminal. Black to apparatus frame. Turn on charger. Reverse steps to take off.

50

List 11 checks that the driver should perform on the fire pump each day.

Operate the pump/drive control. Check fluid level in priming oil tank. Auxiliary fuel tank full. Check all gauges and valves on pump panel. Ensure pump and lines are drained of water. Operate the controls. Full water and foam tanks. Check for water or foam leaks. Check for damage,leaks, or obstructions in any auxiliary winterization system. Test roof and bumper turrets. Check all components of a auxiliary fire suppression system on board (halon, dry chem, etc) for damage, leaks, or corrosion.

51

List nine checks that the driver should perform on the fire pump weekly.

Flush the pump with clear water if the pump always carries water. Check and clean the intake strainers. Check the pump gear box for proper oil level and traces of water. Operate the pump primer with all pump valves closed. Operate the changover valve while pumping from the booster tank in the case of multistage pumps (volume/pressure). Check the packing glands for excessive leaks. Operate the pump pressure control device (pressure relief valve). Test the accuracy of the foam proportioning system. Refer to the pump manufacture for additional instructions.

52

Some checks should also be done on a as needed basis along with there routine checks. Give a example of when this would need to be done.

Pumping from a unclean water source.

53

T or F Using a systematic approach to the vehicle inspection process helps to ensure that the vehicle is checked in the same way every time, and this reduces the chances of anything being overlooked.
