HAZARD SYMBOLS
PRECAUTIONS & WARNINGS
Air compressors are high-speed mechanical equipment requiring caution in operation to minimize harm to property and
personnel. There are many obvious safety rules that must be observed in the operation of this type of equipment.
Therefore not all safety precautions that must be observed with compressors and compressed air systems are listed here.
Failure to follow any of these warnings may result in severe personal injury, death, property damage and/or compressor
damage.
- Air from this compressor will cause severe injury or death if used for breathing or food processing. Air used for
these processes must meet O.S.H.A. 29 C.F.R. 1910.134 or F.D.A178.3570 regulations.
- This compressor is designed for use in the compression of normal atmospheric air only. No other gases, vapors or
fumes should be exposed to the compressor intake, nor processed through the compressor.
- Turn off and lockout/tagout (per O.S.H.A. regulation 1910.147) the main power switch, then release all pressure
from the system, before attempting to service or perform maintenance procedures.
- Relieve all pressure internal to the compressor prior to servicing per O.S.H.A. regulation 1910.147. Do not depend
on check valves to hold system pressure.
- A properly sized safety relief valve must be installed in the discharge piping before (downstream) any shut-off
valve, heat exchanger, orifice or any potential blockage point. Failure to install a safety relief valve could result in
rupturing or explosion of some compressor or safety component.
- Do not operate the compressor over the A.S.M.E. pressure vessel rating for the receiver or the service rating of the
compressor, whichever is lower.
- Do not change the pressure setting of the safety relief valve, restrict function of the safety relief valve or replace the
safety relief valve with a plug. Over pressurization of some system or compressor component can occur, resulting
in severe personal injury, death and property damage.
- Do not operate the unit with any of its safety guards, shields, or screens removed.
- Do not attempt to service any part of the unit while the compressor is operating.
- Never use plastic pipe or rubber hose not specifically rated for the necessary pressure and temperature, or lead-in
soldered joints in any part of the compressed air system.
- Do not remove or paint over any DANGER!, WARNING!, CAUTION! or instructional materials attached to the
compressor. Lack of information regarding hazardous conditions can cause property damage or personal injury,
or death.
