•
All electrical leads are secure and in good order
•
Safety valves and other pressure-relief devices are not obstructed by dirt or paint
•
Air outlet valve and air net, i.e. pipes, couplings, manifolds, valves, hoses, etc. are in good repair, free of wear or
abuse
8.
If warm cooling air from compressors is used in air heating systems, e.g. to warm up a workroom, take precautions
against air pollution and possible contamination of the breathing air.
9.
Do not remove any of, or tamper with, the sound-damping material.
10.
Never remove or tamper with the safety devices, guards or insulations fitted on the machine. Every pressure vessel or
auxiliary installed outside the machine to contain air above atmospheric pressure shall be protected by a pressure-
relieving device or devices as required.
4.3. Safety precautions during maintenance or repair
General precautions
1.
The operator must employ safe working practices and observe all related local work safety requirements and
regulations.
2.
If any of the following statements does not comply with the applicable legislation, the stricter of the two shall apply.
3.
Installation, operation, maintenance and repair work must only be performed by authorised, trained, specialised
personnel.
4.
The compressor is not considered capable of producing air of breathing quality. For air of breathing quality, the
compressed air must be adequately purified according to local legislation and standards.
5.
Before any maintenance, repair work, adjustment or any other non-routine checks, stop the compressor, press the
emergency stop button, switch off the voltage and depressurise the compressor. In addition, the power isolating switch
must be opened and locked.
6.
Never play with compressed air. Do not apply the air to your skin or direct an air stream at people. Never use the air to
clean dirt from your clothes. When using the air to clean equipment, do so with extreme caution and wear eye
protection.
Precautions during maintenance or repair
1.
Always wear safety glasses.
2.
Use only the correct tools for maintenance and repair work.
3.
Use only genuine spare parts.
4.
All maintenance work shall only be undertaken when the machine has cooled down.
5.
A warning sign bearing a legend such as "work in progress; do not start" shall be attached to the starting equipment.
6.
Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one
checking or working on the machine. To this end, a suitable notice shall be affixed to the remote start equipment.
7.
Close the compressor air outlet valve before connecting or disconnecting a pipe.
8.
Before removing any pressurized component, effectively isolate the machine from all sources of pressure and relieve
the entire system of pressure.
9.
Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions against toxic vapours
of cleaning liquids.
10.
Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts and exposed
openings with a clean cloth, paper or tape.
11.
Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely purged, e.g. by
steam-cleaning, before carrying out such operations. Never weld on, or in any way modify, pressure vessels.
12.
Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the machine shall be
stopped but no inspection covers shall be opened before sufficient cooling time has elapsed; this to avoid the risk of
spontaneous ignition of the oil vapour when air is admitted.
13.
Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc
14.
Make sure that no tools, loose parts or rags are left in or on the machine.
15.
All regulating and safety devices shall be maintained with due care to ensure that they function properly. They may not
be put out of action.
