Certification: A-35 is the FDNY Certificate of Fitness associated with operating and maintaining air compressors.
Permit threshold: FDNY currently states that a permit is required for compressors compressing non-flammable gas, including air, above 100 psi, with an
outdoor-air-compressing exception except at a fair or festival. ■cite■turn1search0■
Compressor types: reciprocating, centrifugal and rotary designs use different mechanical methods to raise gas pressure.
Safety: relief protection, pressure indication, cooling, lubrication protection and control devices are central concepts.
Maintenance: inspection, lubrication, cooling, housekeeping and controlled shutdown/isolation prevent avoidable failures.
Emergency response: recognize abnormal conditions, protect people, use approved shutdown procedures and notify the appropriate responsible personnel.
RAPID MEMORY CUES
GAUGE = tells you pressure. RELIEF = protects from overpressure. COOLING = controls compression heat. LUBE = protects moving parts. INTERLOCK =
prevents unsafe operation. ALARM = tells you something needs attention. ISOLATE = control stored energy before maintenance.
