AFETY DURING USE AND OPERATION
1 When the unit has to operate in a fire-hazardous environment, each
engine exhaust has to be provided with a spark arrestor to trap
incendiary sparks.
2 The exhaust contains carbon monoxide which is a lethal gas. When the
unit is used in a confined space, conduct the engine exhaust to the
outside atmosphere by a pipe of sufficient diameter; do this in such a
way that no extra back pressure is created for the engine. If necessary,
install an extractor. Observe any existing local regulations. Make sure
that the unit has sufficient air intake for operation. If necessary, install
extra air intake ducts.
3 When operating in a dust-laden atmosphere, place the unit so that dust is
not carried towards it by the wind. Operation in clean surroundings
considerably extends the intervals for cleaning the air intake filters and
the cores of the coolers.
4 Close the compressor air outlet valve before connecting or
disconnecting a hose. Ascertain that a hose is fully depressurized before
disconnecting it. Before blowing compressed air through a hose or air
line, ensure that the open end is held securely, so that it cannot whip and
cause injury.
5 The air line end connected to the outlet valve must be safeguarded with
a safety cable, attached next to the valve.
6 No external force may be exerted on the air outlet valves, e.g. by pulling
on hoses or by installing auxiliary equipment directly to a valve, e.g. a
water separator, a lubricator, etc. Do not step on the air outlet valves.
7 Never move a unit when external lines or hoses are connected to the
outlet valves, to avoid damage to valves, manifold and hoses.
8 Do not use compressed air from any type of compressor, without taking
extra measures, for breathing purposes as this may result in injury or
death. For breathing air quality, the compressed air must be adequately
purified according to local legislation and standards. Breathing air must
always be supplied at stable, suitable pressure.
9 Distribution pipework and air hoses must be of correct diameter and
suitable for the working pressure. Never use frayed, damaged or
deteriorated hoses. Replace hoses and flexibles before the lifetime
expires. Use only the correct type and size of hose end fittings and
connections.
10 If the compressor is to be used for sand-blasting or will be connected to
a common compressed-air system, fit an appropriate non-return valve
(check valve) between compressor outlet and the connected sand-
blasting or compressed-air system. Observe the right mounting position/
direction.
11 Before removing the oil filler plug, ensure that the pressure is released
by opening an air outlet valve.
12 Never remove a filler cap of the cooling water system of a hot engine.
Wait until the engine has sufficiently cooled down.
13 Never refill fuel while the unit is running, unless otherwise stated in the
Atlas Copco Instruction Book (AIB). Keep fuel away from hot parts
such as air outlet pipes or the engine exhaust. Do not smoke when
fuelling. When fuelling from an automatic pump, an earthing cable
should be connected to the unit to discharge static electricity. Never spill
nor leave oil, fuel, coolant or cleansing agent in or around the unit.
14 All doors shall be shut during operation so as not to disturb the cooling
air flow inside the bodywork and/or render the silencing less effective.
A door should be kept open for a short period only e.g. for inspection or
adjustment.
15 Periodically carry out maintenance works according to the maintenance
schedule.
16 Stationary housing guards are provided on all rotating or reciprocating
parts not otherwise protected and which may be hazardous to personnel.
Machinery shall never be put into operation, when such guards have
been removed, before the guards are securely reinstalled.
17 Noise, even at reasonable levels, can cause irritation and disturbance
which, over a long period of time, may cause severe injuries to the
nervous system of human beings.
When the sound pressure level, at any point where personnel normally
has to attend, is:
below 70 dB(A): no action needs to be taken,
above 70 dB(A): noise-protective devices should be provided for
people continuously being present in the room,
below 85 dB(A): no action needs to be taken for occasional visitors
staying a limited time only,
above 85 dB(A): room to be classified as a noise-hazardous area and
an obvious warning shall be placed permanently at
each entrance to alert people entering the room, for
even relatively short times, about the need to wear
ear protectors,
above 95 dB(A): the warning(s) at the entrance(s) shall be completed
with the recommendation that also occasional
visitors shall wear ear protectors,
above 105 dB(A): special ear protectors that are adequate for this noise
level and the spectral composition of the noise shall
be provided and a special warning to that effect shall
be placed at each entrance.
18 Insulation or safety guards of parts the temperature of which can be in
excess of 80 °C (175 °F) and which may be accidentally touched by
personnel shall not be removed before the parts have cooled to room
temperature.
19 Never operate the unit in surroundings where there is a possibility of
taking in flammable or toxic fumes.
20 If the working process produces fumes, dust or vibration hazards, etc.,
take the necessary steps to eliminate the risk of personnel injury.
21 When using compressed air or inert gas to clean down equipment, do so
with caution and use the appropriate protection, at least safety glasses,
for the operator as well as for any bystander. Do not apply compressed
air or inert gas to your skin or direct an air or gas stream at people.
Never use it to clean dirt from your clothes.
22 When washing parts in or with a cleaning solvent, provide the required
ventilation and use appropriate protection such as a breathing filter,
safety glasses, rubber apron and gloves, etc.
23 Safety shoes should be compulsory in any workshop and if there is a
risk, however small, of falling objects, wearing of a safety helmet should
be included.
24 If there is a risk of inhaling hazardous gases, fumes or dust, the
respiratory organs must be protected and depending on the nature of the
hazard, so must the eyes and skin.
25 Remember that where there is visible dust, the finer, invisible particles
will almost certainly be present too; but the fact that no dust can be seen
is not a reliable indication that dangerous, invisible dust is not present in
the air.
26 Never operate the unit at pressures or speeds below or in excess of its
limits as indicated in the technical specifications.
27 Never operate the generator in excess of its limits as indicated in the
technical specifications and avoid long no-load sequences.
28 Never operate the generator in a humid atmosphere. Excessive moisture
causes worsening of the generator insulation.
29 Do not open electrical cabinets, cubicles or other equipment while
voltage is supplied. If such cannot be avoided, e.g. for measurements,
tests or adjustments, have the action carried out by a qualified electrician
only, with appropriate tools, and ascertain that the required bodily
protection against electrical hazards is applied.
30 Never touch the power terminals during operation of the machine.
31 Whenever an abnormal condition arises, e.g. excessive vibration, noise,
odour, etc., switch the circuit breakers to OFF and stop the engine.
Correct the faulty condition before restarting.
32 Check the electric cables regularly. Damaged cables and insufficient
lightening of connections may cause electric shocks. Whenever
damaged wires or dangerous conditions are observed, switch the circuit
breakers to OFF and stop the engine. Replace the damaged wires or
correct the dangerous condition before restarting. Make sure that all
electric connections are securely tightened.
