SAFETY PRECA UTIONS (continued)
14.If the ground is not level or can be subject to variable inclination, consult Atlas Copco.
15.The electrical connections shall correspond to the local codes. The units shall be grounded and protected against short circuits by fuses.
Operation
1.Airhosesshallbeofcorrectsizeandsuitablefortheworkingpressure. Never use frayed, damaged or deteriorated hoses. Use only the correct type and size of hose end fittings and connections. When blowing through a hose or air line, ensure that the open end is held securely. A free end will whip and may cause injury. Make sure that a hose is fully depressurized before disconnecting it.
Never play with compressed air. Do not apply it to your skin or direct an air stream at people. Never use it to clean dirt from your clothes. When using it to clean equipment, do so with extreme caution and use eye protection.
2.The compressor is not considered as capable of producing air of breathing quality. Forbreathingairquality, the compressed air must be adequately purified according to local legislation and standards.
3.Never operate the units when there is a possibility of taking in flammable or toxic fumes.
4.Never operate the units at pressures below or in excess of their limit ratings as indicated on the Principal Data sheet.
5.Keep all bodywork doors shut during operation. The doors may be opened for short periods only, e.g. to carry out checks. W ear ear protectors when opening a door.
6.People staying in environments or rooms where the sound pressure level reaches or exceeds 90 dB(A) shall wear ear protectors.
7.Periodically check that:
a.All guards are in place and securely fastened
b.Allhosesand/orpipesinsidetheunitareingoodcondition,secure and not rubbing
c.There are no leaks
d.All fasteners are tight
e.All electrical leads are secure and in good order
.f Safety valves and other
g.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
Maintenance
Maintenance and repair work shall only be carried out under supervision of someone qualified for the job.
1.Use only the correct tools for maintenance and repair work.
2.Use only genuine spare parts.
3.All maintenance work, other than routine attention, shall only be undertaken when the unit is stopped, the main power supply is switched off and the machine has cooled down. Take positive precaution to ensure that the unit cannot be started inadvertently.
In addition, a warning sign bearing a legend such as "work in progress; do not start" shall be attached to the starting equipment.
4.Before removing any pressurized component, effectively isolate the unit from all sources of pressure and relieve the entire system of pressure.
5.Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions against toxic vapours of cleaning liquids.
6.Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts and exposed openings with a clean cloth, paper or tape.
7.Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely purged, e.g. by
Never weld on, or in any way modify, pressure vessels.
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.
Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
8.Make sure that no tools, loose parts or rags are left in or on the unit.
9.Before clearing the unit for use after maintenance or overhaul, check that operating pressures, temperatures and time settings are correct and that the control and
10.Every time the separator element is renewed, examine the discharge pipe and the inside of the oil separator vessel for carbon deposits; if excessive, the deposits should be removed.
11.Protect the motor,airfilter, electrical and regulating components, etc. to prevent moisture from entering them, e.g. when
12.Make sure that all
13.Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.
14.The following safety precautions are stressed when handling refrigerant:
a.Never inhale refrigerant vapours. Check that the working area is adequately ventilated; if required, use breathing protection.
b.Always wear special gloves. In case of refrigerant contact with the skin, rinse the skin with water. Ifliquidrefrigerantcontacts the skin through clothing, never tear off or remove the latter; flush abundantly with fresh water over the clothing until all refrigerant is flushed away; then seek medical first aid.
c.Always wear safety glasses.
15.Protect hands to avoid injury from hot machine parts, e.g. during draining of oil.
Note: W ith stationary machine units driven by an internal combustion engine, allowance has to be made for extra safety precautions, e.g. spark arrestors, fuelling care, etc. Consult Atlas Copco.
