FDNY A35 COMPREHENSIVE CORRECT
QUESTIONS AND ANSWERS SURE A+
✔✔Maintenance on the Pressure Switch - ✔✔1. Start compressor, allow air in receiver
to build to normal operating levels while paying attention to the pressure gauge.
2. When gauge indicates pressure above normal, compressor should shut down
automatically. If not, pressures witch may be adjusted. If this doesn't work switch is
defective and must be replaced.
(Some compressors operate continuously as their pressure switch device just prevents
compressor from compressing air. to test this just make sure air is no longer
compressing when level is reached.)
✔✔Maintenance on the Pressure Relief Valve - ✔✔Run compressor with pressure
switch fully open, when it fully open it cannot shut down the compressor.
Should be set at no less than 15 psi or 10% above the operating pressure of the
compressor (which ever is greater) but never higher than max allowabe working
pressure of receiver.
✔✔Maintenance of the Operating Temperature - ✔✔Acceptable temperatures are in the
maintenance manual.
Overheating can cause damage to compressor and is a potential fire hazard.
If overheating discovered water cooling mechanism must be checked. Any blockages,
leaks, or other defects must be repaired and defective parts replaced.
✔✔What is lockout/tagout? - ✔✔A safety procedure to ensure dangerous machines are
properly shut off during maintenance.
, ✔✔Lockout/Tagout Safety Procedures - ✔✔Lock the device or the power source with a
hasp and placing it in such a position that no hazardous power sources can be turned
on. Also requires a tag to be affixed to the lockout device indicating it should not be
turned on.
Know OSHA Standard for Control of Hazardous Energy (Lockout/Tagout) procedure.
✔✔Compliance with Lockout/Tagout - ✔✔Prevents an estimated 120 fatalities and
50,000 injuries each year.
Workers injured from exposure to hazardous energy lose an average of 24 workdays for
recuperation.
✔✔ Air compressors are used to? - ✔✔Power industrial equipment and construction
tools.
✔✔Air Compressors enable? - ✔✔The efficient repair of all types of vehicles and
facilitate their safe operation.
✔✔Air compressors are important in? - ✔✔Manufacturing and are central to product
development and creation.
✔✔A FDNY permit is required if a compressor is? - ✔✔Used to compress any
nonflammable, corrosive or oxidizing gas, including air to a pressure exceeding 100 psi.
(Outdoor air compressing does not require a permit unless it is a fair or festival)
✔✔What does an air compressor do? - ✔✔It takes the air in a room and forces it into a
container under pressure.
✔✔Compressed air is used to power? - ✔✔Pneumatic wrenches and lifts in automobile
service stations. Heavy machinery and paint spray booths in industrial plants.
✔✔What are the different types of air compressors? - ✔✔Reciprocating, centrifugal,
rotary and scroll compressors.
✔✔What is the difference between air compressor types? - ✔✔How they compress air.
✔✔What is the most used air compressor? - ✔✔Reciprocating.
✔✔What are air compressors sometimes called? - ✔✔Air pumps.
✔✔How can air compressors be powered? - ✔✔Electric motors, internal combustion
engines, and steam turbines.
