FDNY A-35 questions with answers graded A+ 2023
Air compressors power... –
Answer - (1) industrial equipment and (2) construction tools
Examples of equipment powered by air compressor –
Answer - pneumatic wrenches, lifts inauto 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 buildup 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 aboveground 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.
