SAFETY 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
- 9 -
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 The unit has parts, which may be accidentally touched
by personnel, of which the temperature can be in exess
of 176°F (80°C). The insulation or safety guard,
protecting these parts shall not be removed before the
parts have cooled down 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 Do not use aerosol types of starting aids such as ether.
Such use could result in an explosion and personal
injury.
