If severe vibration is observed, the cause of this should be immediately investigated and the situation rectified. Excessive
vibration can lead to fatigue and other failures. Similarly, if during operation a significant change is noticed in the level of
vibration, noise, temperature or any other parameter, the cause of such changes must be determined, and the cause
rectified.
Inlet filters must be inspected regularly so that liquid or debris is not allowed to enter the machine, which could cause
damage and consequently injury to personnel.
During routine maintenance, coupling alignment should be checked for misalignment.
Only approved lubricants must be used and quantities, etc must be checked regularly.
Before restarting after servicing, all nuts, set screws, etc must be checked for tightness, check all joints, for leaks and
carry out purging as necessary before introducing the process gas.
Also, before start-up, check the machine inlet and outlet isolating valves are open both non-return valves (if fitted) are
the correct orientation.
Adjacent pipework and equipment must not impose undue forces and moments on the machinery flanges.
All welding work must be carried out be an approved gas coded welder.
In order to prevent reverse rotation of machines, it is ESSENTIAL that a non-return valve be installed in the inlet
pipework. Otherwise a hazardous situation can arise during a normal shutdown or if the prime mover power supply is
interrupted for a period of time.
The environment around the installation may need to be monitored in order to detect gas leaks etc., and consideration
must be given to the installation of gas detecting equipment, and the class of electric equipment.
If installation components are only accessible using a pedestal or stairs, then this pedestal or stair may present a falling
hazard. Secure the pedestal or stair with a railing or handrail!
The environment around the installation may need to be monitored in order to detect trip hazards. Tubes, cables etc. laid
around the floor may cause a tripping hazard.
Leakages of hazardous fluids from shaft seals can occur, these should be contained, to avoid any harm to personnel or
the environment.
Care must be taken when dismantling the machine as there may be possible harmful substances from the pumping media
remaining in the compressor/booster.
If the machine is located in a hazardous or zoned area, it is important to prevent unauthorised modes of operation.
Failure to do so may result in the temperature limits being exceeded.
