1.4 Safety during use and
operation
1 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.
2 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.
3 Periodically carry out maintenance works according
to the maintenance schedule.
4 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.
5 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 recom-
mendation 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.
6 Never operate the unit in surroundings where there
is a possibility of taking in flammable or toxic
fumes.
7 If the working process produces fumes, dust or
vibration hazards, etc., take the necessary steps to
eliminate the risk of personnel injury.
8 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.
9 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.
10 Safety shoes should be compulsory in any work-
shop and if there is a risk, however small, of falling
objects, wearing of a safety helmet should be
included.
11 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.
12 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.
13 Never operate the ESS in excess of its limits as
indicated in the technical specifications.
14 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.
15 Never touch the power terminals during operation
of the machine.
16 Whenever an abnormal condition arises, e.g.
excessive vibration, noise, odour, etc., switch the
circuit breakers to OFF and stop the ESS. Correct
the faulty condition before restarting.
17 Check the electric cables regularly. Damaged cables
and insufficient tightening of connections may
cause electric shocks. Whenever damaged wires or
dangerous conditions are observed, switch the
circuit breakers to OFF. Replace the damaged wires
or correct the dangerous condition before restarting.
Make sure that all electric connections are securely
tightened.
