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 The unit has parts, which may be accidentally touched by personnel, of which the temperature can be
in exess of 80 °C (176 °F). 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.
