FDNY A 35 COMPREHENSIVE STUDY
GUIDE WITH TESTED SOLUTIONS
⩥ Examples of equipment powered by air compressor. Answer:
pneumatic wrenches, lifts in auto service stations, paint spray booths
⩥ Air compressors enable. Answer: (1) efficient repair of all types of
vehicles; and (2) facilitate their safe operation on public thoroughfares
⩥ Permit is required for air compressor. Answer: that compresses air
above 100 PSI
⩥ Types of air compressors. Answer: (1) reciprocating;
(2) centrifugal;
(3) solar; and
(4) rotary
*Difference is the way in which they compress air
⩥ How do air compressors work. Answer: take the air in a room and
force it into a container UNDER PRESSURE. The more air forced into
, the container, the greater the pressure. Compressed air can be discharged
from the container at a controlled rate.
⩥ Most common air compressor. Answer: Reciprocating
⩥ Air compressors are sometimes called. Answer: air pumps
⩥ Air compressors can be powered by:. Answer: (1) electric motors;
(2) internal combustion engines; or
(3) steam turbines
⩥ Explosions & air compressors. Answer: If there is a build up of
flammable gases (ex: in service stations and workshops), those gases are
heavier than air and fall to the floor before spreading outward. These
gases are easily ignited by sparks and high temperatures--which
INCLUDES the heat generated by an air compressor.
⩥ To avoid explosions w/ air compressors. Answer: Raise air
compressor at LEAST 5 feet above ground level so that no flammable
gases are drawn into the compressor. To meet the height requirement you
can place compressor on a shelf or bench OR the air receiver tank may
be turned and stood on end w/ the air compressor bolted to the top of the
tank.
