FDNY A-35 QUESTIONS AND
CORRECT ANSWERS
Safety Relief Valves ✅✅ANSW-safety component.
keep compressor tank from bursting if pressures witch stops working
Constant Speed Control Switch ✅✅ANSW-safety component.
Used when steady/constant demand for compressed air.
If demand drops excess compressed air is released through pressure release valve.
Cooling system ✅✅ANSW-safety component.
compression chamber and compressed air must be cooled to avoid overheating.
Small compressors are air-cooled (fan).
Large compressors are water-cooled.
Low Oil Level Indicator Switch ✅✅ANSW-safety component.
automatically shut down compressor if oil is low.
Serious damage can be caused if compressor is operated w/ low oil
Maintenance & Repairing Compressor- General Requirements ✅✅ANSW--always follow
guidelines outlined by manufacturer.
Repair:
, -always turned off
-electrical supply shutdown
-air drained
-made by qualified technician
Repairs by CF ✅✅ANSW--must know how to correct cooling system;
-may replace belts
-change air filter
-change lubrication oil
Leaks ✅✅ANSW-CF must look & listen for leaks.
More prominent in colder months when sealing materials shrink.
Most leakage occurs at tubing and fittings at air reciever tank.
Heat & Compressor ✅✅ANSW--never place combustible materials nearby;
-do not use near devices that produce heat;
solar heat is not known to cause overheating
CF Responsibility ✅✅ANSW--visually inspect
-remain in area for a few minutes after compressor started
-do not operate at speeds above recommended ranged
Injury from Compressor ✅✅ANSW--Dust or debris blow off clothing can be driven under skin
causing DEATH
-Eardrum ruptures at 40 PSI
-Air entering mouth can destroy lungs and internal organs
-Eyesight (always wear googles)
