IFSTA Chapter 2 Flashcards
NFPA 1002 also requires that drivers be skilled in…..
Performance of certain maintenance checks
Maintenance vs repairs
Maintenance keep apparatus in a state of usefulness or readiness
repair means to restore that which has become inoperable
NFPA 1002 requires drivers be able to perform these following routines tests and inspections
Batteries
Belts
Oil
Tires
hydraulic fluids
tools, appliances and equipment
Coolant Systems
Braking Systems
Steering systems
electrical systems
fuel systems
NFPA _________ denotes out of service criteria
NFPA 1911
Methods for washing vehicles first 6 months
While Paint and protective coating are new vehicle should be washed frequently using cold water to harden the paint and keep from spotting
Washing Steps Recommendations
Use Garden hose without nozzle
Rinse Loose dirt prior to applying soap
Avoid extremely hot water
Wash from top to bottom
Dry with clean Chamois or rubber squeegee
Glass Care on Vehicles
Warm Soapy water or commercial glass cleaner
Paper Towels or Clean Cloth Rags
Shop towels NOT ACCEPTABLE
Interior Vehicle Cleaning and Lubrication
Warm Soapy Water
Use only product specified by manufacturer
Avoid solvents ( Bleach, Laquer, Acetone, Laundry soap )
Ventilate Cab
Mind electrical systems
Keep compartments, hinges, slide tracks and seals clean and lubed
Waxing a vehicle
Reference manufacturer’s manual before waxing
Wait for apparatus to be at least 6 months old
Walk Around method inspection
Begin at drivers door on the cab and walk clockwise around apparatus
upon completion get in cab an start apparatus to perform functional checks
Weather permitting apparatus should be checked
Parked outside for functional tests with chocked wheels
What to look for during Tire Checks
Make certain tire types match
Not acceptable to mix radial with bias-ply tires
Tires must be same size and weight ratings per manufacturer spec
Tire Depths, tread separation, cupping, excessive wear on sidewalls, cuts dry rotting, cracking tires, impaled objects
Tire Specs are based on what weight
Speed rating
Tire Pressure recommended
BASED on GAWR ( Gross Axel weight rating)
Max Speed is rated upper limit of tire performance
Max tire pressure printed on the tire exterior is NOT the recommended operating tire pressure
Per NFPA ______. Tires must be inflated to
Apparatus manufacturer’s recommendation per NFPA 1911
What prevents an electric overload on a vehicle
Load Management System
(LMS)
What is OVERLOAD
A problem due to a large amount of electrical equipment added to modern fire apparatus
What is Incorporated with a load manager
What does it do
Load Sequencer or monitor which turns on various lights at specified intervals
Load Monitor shutting down less important equipment is known as…..
Load Shedding : To Prevent Overload
Steering systems check
Excess play that does not result in actual movement of vehicle wheels
Play should not be more than 10º in either direction
Curb Weight vs GVWR
Curb Weight: Empty apparatus fresh off assembly line
GVWR: Max weight at which a vehicle can be safely operated on roadways in ideal conditions
NFPA 1901 and 1911 side to side variance
Cannot exceed 7% of variance in weight
Air-Actuated Braking Systems
Braking system that uses compressed air to hold off a springs brake “Parking Brake” and applies air pressure to a service brake for vehicle stopping
What does the Air Pressure protecting valve prevent and under what psi level
Prevents air horns or other non essential devices from use below 80 psi
NFPA standard for testing brakes
NFPA 1911
Engine compartment inspection (under cab)
Shall not be performed while engine is running
Never rely solely on warning lights or gauges
All Fluid levels should be inspected
Cab should be lifted on a weekly basis
DPF is?
Diesel Particulate Filters
SCR is? And how does it work
Selective catalyst reductant
May be equipped on engines produced after Jan 1st 2010
Uses DEF stored downstream from (DPF) and is injected into exhaust gas in order to reduce (NOx) emissions
Inspection of exhaust system
Look for Cracks and Leaks
High Heat during regen process may cause components surrounding exhaust to catch fire if there is a leak within the system
SAE oil is?
Society of Automotive Engineers followed by a number noting viscosity of oil
Vehicle Battery Inspection
Cable Connections are tight and protected with a film of grease check for cracks or leaks
What chemical can vehicle batteries produce
Hydrogen Gases
Considerations when jump starting a vehicle
Ensure both systems have the same power voltage to prevent damage
Ensure jumper cables are connected to the specified battery per recommendations
After what operation shall the pump be throughly flushed
Anytime the pump has been drafting from salt water, lake or pond or areas served by old water mains
