CH1 Flashcards
(45 cards)
The D/O primary goals include
Promote reliability, reduce the frequency & cost of repairs, limit out-of-service time, eliminate unexpected & catastrophic failures
Pg 10
The AHJ’s (SOPs) dictate a program for the
inspection, maintenance, and testing of emergency vehicles
Pg 10
Seepage of liquid as indicated by wetness or discoloration not great enough to cause drops
Class 1
Pg 14
Great enough to form drops but not enough for them to fall from the item being inspected
Class 2
Pg 14
Great enough for drops to form and fall from the item being inspected
Class 3
Pg 14
Dampness on fuel suction lines may indicate
That air is leaking into the system
Pg 15
Fuel line leaks should be reported ASAP, as Class 2 leakage of fuel are considered
Out-of-service criterion
Pg 15
An oil leak that meets the Class 3 designation is considered an
out-of-service criterion
Pg 15
Contamination is the transfer of
A hazardous material to person, equipment, and the environment in greater than acceptable quantities
pg 16
The safest practice to prevent carcinogen exposure is to avoid combustion products using
sensible planning, team communication, and careful observance of scene conditions.
pg 16
Exposure means that a hazardous material has entered or potentially entered your body via
routes of entry
IE: swallowing, breathing, or contacting skin or mucous membranes
pg 16
When performing visual checks of the engine compartment, follow the acronym “CDLPMS”
Cracks, dents, leaks, properly mounted, and secured
pg 23
Unlike coolant and engine oil that is consumable, a decrease in hydraulic fluid level is most likely due to a
leak somewhere in the system
pg 25
Watch these systems if they are overflowing at the reservoir tank with foam, as there could be
a loose connection or perforated suction line
pg 25
Before setting the seat, mirrors, and steering wheel for personal needs, follow the manufacturer’s instructions to allow the gauges to initiate
The prove-out (self-check) stage
pg 25
Anti-lock braking systems reduce the possibility of an apparatus going into a
slide, jack knife, or spin during heavy braking
pg 28
ABS brakes also assist the D/O in keeping the apparatus in a
straight trajectory during heavy or emergency braking
pg 28
ABS technology does not necessarily provide a faster stop, but it
greatly enhances the likelihood of a controlled stop
pg 28
Apparatus brakes should be thoroughly testes at least annually in accordance with
NFPA 1010
pg 28
In addition to a DPF system, most engines produced after Jan 1,2010, may be equppied with an exhaust after-treatment system called
Selective catalytic reduction
pg 29
AN SCR system uses _______ to further reduce emissions
DEF
pg 29
DEF is injected into the exhaust _________ of the DPF in order to reduce the ___________ emissions from diesel engines
Downstream; Nitrogen Oxide (NOx)
pg 29
Modern fire apparatus are equipped with electrical _______ that are intended to prevent __________ of a vehicle’s electrical generation system
Load management systems; overload
pg 30
The load sequencer turns on various lights at specified intervals so that
The startup electrical load for all the devices does not occur at the same time
