Flashcards in Pump Ops Chapert 2 Deck (48):
Regardless of the number of incidents a fire apparatus responds to during the course of a day:
It must be ready to respond and capable of performing its intended function with peak efficiency at all times.
Maintenance refers to:
Keeping apparatus in a state of usefulness and readiness
Repair means to:
Restore that which has become inoperable
Preventive maintenance helps to ensure:
Reliability, reduce the frequency and cost of repairs, and reduces out of service time.
The goal of preventive maintenance is to:
Eliminate unexpected and catastrophic failures that may endanger firefighter and the general public.
Nfpa 1002 requires driver operators to be able to perform routine tests inspections and servicing of the following systems:
Batteries, braking systems, coolant system electrical system, fuel system, hydraulic system, oil, tires, steering system, belts, tools, appliances, and equipment.
Minor deficiencies such as low fluid levels or burned out bulbs are often corrected as part of the maintenance function of the:
Whenever the apparatus or a piece of equipment onboard is found broken, defective or in need of any type of repair the driver/operator:
Should follow the established policy of the ahj for documenting, reporting and following up on the status of the repair.
A clean engine permits:
Proper inspection for leaks and their source
After a heavy cleaning it may be necessary to perform a:
Routine lubrication to ensure that all components are properly protected from excessive wear.
During the first six monthy after an apparatus is received while paint and protective coating are unseasoned:
The vehicle should be washed frequently using cold water to harden the paint to keep it from spotting.
Rinse as much loose dirt as possible from the vehicle before applying soap, high pressure can drive dirt and debris into the finish and never:
Remove dirt by dry rubbing
To clean automotive glass:
Use warm soapy water or commercial glass cleaner with paper towels or clean cloth rags.
Interior cleaning. Avoid using solvents such as:
Lacquer thinner, acetone, laundry soap bleach and naphtha.
Wait... Months before applying wax with new apparatus:
The incoming driver operator should consult the person being relieved or any pertinent info regarding:
Incident activity, equipment usage or problems
Two types of inspection are actually conducted during a walk around inspection:
The operational readiness inspection and the vehicle pretrip road worthiness inspection.
The driver begins the walk around inspection at the
Drivers door on the cab and works around the apparatus in a clockwise pattern.
When approaching a vehicle to be inspected the driver should observe:
Any problems that may be readily apparent from a distance such as body damage or a severe lean to one side
The terrain on which the vehicle is parking.
Vehicle fluid leaks.
Weather permitting the apparatus should be:
Parked outside for functional tests and wheels chocked.
The drivers visual inspection of the vehicle should include checking items for:
Condition, cleanliness, damage, defects functionality, leaks and presence of or missing items.
Most importantly the driver should check the tire:
Type, condition and inflation
Drivers should mak certain that tire types:
All tires should be the same:
Size and weight ratings. According to appropriate manufacturer specs
The correct tire for any commercial vehicle is detemined after the vehicles specs are final. Tire selection for fire apparatus are based on:
Gross axle weight ratings
Drivers should check for proper tread depth,:
Tread separation, cupping, excessive wear on the sidewalls, cuts, dry rotting cracking tire or objects impaled in the tire.
Nfpa 1911 requires that all tires be replaced every ..... Years regardless of their condition.
Once the exterior of the apparatus has been checked the driver may:
Enter the cab to begin inter inspecting. Adjust mirrors, seats and seat belts; start the engine, and check all dashboard instrument for correct readings.
The load sequencer turns on:
Various lights at specified intervals
The load monitor:
Watches the system for any added electrical loads that threaten to overload the system.
If overload condition occurs the load monitor will:
Shut down less important electrical equipment in order to prevent the overload. This is referred to as load shedding
In general steering wheel play should be no more than approximately:
10 degrees in either direction.
On a 20" steering wheel that is 2" in each direction
Curb weight is:
The weight of an empty fire apparatus fresh off the assembly line with no tools, water equipment or passengers.
The manufacturer determines the GVWR as:
The maximum weight at which a vehicle can be safely operated on roadways in ideal conditions
The GVWR placard may indicate:
The maximum weight for each axle on the apparatus along with the tire pressure recommendations
Before placing any apparatus in service load all compartments with the intended in service equipment. Hose, water, and crew. Weigh each axle and compare the results to the gross axle weight ratio GAWR placard. If weights are higher than the GAWR:
Remove or redistribute equipment until a safe loading is achieved
Apparatus with air brakes are to be equipped with an air pressure protection valve that prevents air horns or other nonessential devices from being operated when the pressure drops below:
ABS reduce the possibility of an apparatus going into:
A slide, jackknife, or spin during heavy braking.
Abs brakes also assist the driver in keeping:
The apparatus in a straight trajectory during heave or emergency braking
Apparatus brakes should be thoroughly tested:
Once the entire exterior of the apparatus has been inspected, the in cab checks have been completed and the air brake testing is complete the driver should:
Shut off the engine and prepare to perform checks on routine preventative maintenance in the engine compartment.
In addition to a dpf system engines produced after january 1, 2010 may be equipped with an exhaust after treatment system called
Selective catalyst reductant SCR
A selective catalyst reduction system used:
Diesel exhaust fluid DEG to help further reduce emissions
Effective lubrication depends on use of the:
Proper grade lubricant,
The frequency of lubrication
The amount used,
And the methodof lubrication
Most automotive batteries contain:
Lead and sulfuric acid
If chassis lubrication is within driver responsibilities talk the following steps to complete the duties:
Be familiar with all lubrication fill points
Wipe fitting clean with shop rag
Press end of lube gun fill hose into fitting
Operate the handle until resistance is felt
Lube all points on vehicle
Ensure that the vehicle being used as the pwer source has the same:
Voltage electrical system as the apparatus being jump started
