FDNY A-35 FREQUENTLY TESTED ACTUAL EXAM
QUESTIONS WITH CORRECT ANSWERS
Question 1.
Air compressors power...
ANSWER
(1) industrial equipment and (2) construction tools
Question 2.
Examples of equipment powered by air compressor
ANSWER
pneumatic wrenches, lifts in auto service stations, paint spray booths
Question 3.
Air compressors enable...
ANSWER
(1) efficient repair of all types of vehicles; and (2) facilitate their safe operation on public
thoroughfares
Question 4.
Permit is re- quired for air compressor
ANSWER
that compresses air above 100 PSI
Question 5.
Types of air compressors
ANSWER
(1) reciprocating;
(2) centrifugal;
(3) solar; and (4) rotary *Difference is the way in which they compress air
Question 6.
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.

, Question 7.
Most common air compressor
ANSWER
Reciprocating
Question 8.
Air compressors are sometimes called
ANSWER
air pumps
Question 9.
can be powered by:
ANSWER
(2) internal combustion engines; or (3) steam turbines
Question 10.
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.
Question 11.
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.
Question 12.
Power to air compressor
ANSWER
entire unit is driven by an electric motor. Motor activates a series of drive belts. Belts power the
moving parts of the unit--like w/ power steering and alternator in automobile
