ch4 intro to apparatus inspection, maintenance, and testing Flashcards
nfpa blank establishes guidelines for record-keeping practice.
1911 standard for the inspection, maintenance, testing, and retirement of in-service automotive fire apparatus
keeping apparatus in a state of usefullness and readiness
maintenance
to restore or replace parts or components, which have become inoperable
repair
career fire departments require driver/operators to perform apparatus inspections and maintenance checks when?
at the beginning of each work period
what are some of the most vulnerable areas in the engine compartment?
linkage, fuel injectors, and other controls
for atleast blank months, wash a new apparatus frequently with cold water to harden the paint and keep it from spotting
6
the maximum weight at which a vehicle can be safely operated on roadways
Gross Vehicle Weight Rating (GVWR)
the weight of an empty fire apparatus off the assembly line with no tools, water, equipment, or passengers
Curb Weight
refers to the distance an activation device, such as a wheel or lever, will move while the system it is part of is inactive
free play
turns various lights on at specified intervals so that the start-up electrical load for all of the deices does not occur at the same time
load sequencer
Watches the system for added electrical loads tht threaten to overload the system
load monitor
when an overload condition occurs, the load monitor will shut down less important electrical equipment to prevent the overload
load shedding
what are the two most important safety inspections that driver/operator will perform every day?
make sure that the apparatus has no compromise in steering and that it will come to a stop
apparatus brakes should be tested thoroughly at least blanke per year
once
By operating the aerial device atleast blank every work period the driver/operator will be more preparted to operate efficiently under emergency conditions
once
1911 primarily describes?
what must be included in the various tests
1901 describes blank testing for new apparatus
acceptance
preservice tests are usually conducted at the?
manufacturer’s facility
Certification tests must be performed by who?
third-party testing agency personnel
nondestructive testing is performed every blank years
5
blank is used to determind whether or not an aerial device is capable of safely handling the amount of weight it is rated to carry
load testing
load testing is a good indication that a blank load can be supported at the tip of a fully extended aerial ladder o rin the basket of an elevating platform
static
blank testing involves any one of several testing methods used to inspect structural components without physically altering, placing under load stress, or otherwise damaging or causing wear to the component
nondestructive
blank is performed on accessible welds and steel components
magnetic particle inspection
Blank ladders can be nondestructively tested through the registering of hardness and by taking conductivity reading throughout the length of the ladder
Aluminum
this inspection is performed on stabilizer pins and mounting bolts, rotation bearing bolts, raising and extension cylinder mounting pins and bolts, aerial hinge pins, and aerial support structure mounting bolts
ultrasonic inspection
Radiographic tests utilize blank
X-ray technology
Acoustice emission inspections use special equipment that identifies flaws in the metal of an aerial device by emitting blank into the device and reading them at a distant point
sound waves
blank tessts are performed to determine that the hydraulic system and structural mechanisms are performing in the proper manner and in accordance with the manufacturer’s specifications
operational timing tests
blank are conducted to assure the purchaser that the apparatus meets the original bid specifications
acceptance tests
