Safety standards for the use and
running
1 When the machine has to be used in an environment
with risk of fire, each of the engine exhaust pipes must
have a spark arrestor, to avoid the risk of fire.
2 Exhaust gases contain carbon monoxide, which is a
lethal gas.When the machine is used in a closed
space, the exhaust gases shall be conveyed to the
outer atmosphere, through a pipe with sufficient
diameter. This operation shall be performed in order
to avoid developing an excessive pressure inside the
engine.If necessary an extractor shall beinstalled.
Comply with all existing local regulations.
Ensure the machine has enough air intake to perform
the operation.If necessary, install additional air ducts.
3 When performing operations in dust-laden
environments, position the machine in order to prevent
the return of dust by wind action.The use of the
machine in dust-free environments significantly extends
the intervals set out to clean the air intake filters and
the cooling system cores.
4 Never remove the filler cap of the cooling system when
the engine is hot.Wait until the engine has cooled.
5 Never fill the engine with fuel while the engine is
running.Keep fuel away from hot parts, such as engine
exhaust pipes.Do not smoke while refueling.If an
automatic pump is used, a ground wire should be
connected to the machine in order to discharge static
electricity. Never spill or release oil, fuel, coolant or
cleaning agents on the machine or around it.
6 All doors must be closed during the machine running,
so as not to impair the air flow inside the work area
and/or making the noise reduction devices ineffective.It
will only be allowed to keep the doors open for short
periods, for example, when performing inspection or
adjustment tasks.
7 Periodically perform maintenance tasks, complying
with the maintenance chart.
8 Fixed guards should be placed on all rotating or
moving parts, which are not duly protected and may
become dangerous for the personnel.If the guards are
removed, do not run the machinebefore having them
reinstalled.
9 Noise, even at acceptable levels, causes irritation and
discomfort that, after long periods of exposure, may
encourage the emergence of serious injury to the human
nervous system.
When the noise level in a workplace is:
- below 70 dB (A):no action is required,
- over 70 dB(A):personal protection equipment
(PPE) against the noise should be provided to the
personnel that is permanently in place,
- below 85 dB (A):no action is required for occasional
visitors that will stay in the location for only a
limited time.
- over 85 dB(A):the place should be classified as a
noise dangerous area, and a notice should be
permanently placed at each of the entrances, warning
people willing to enter the site, even for short
periods of time, that they should wear protective
devices (PPE) for the ears,
- over 95 dB(A):notices at the entrances shall be
complemented with a recommendation that even
occasional visitors shall use ear protective devices
(PPE).
- over 105 dB(A):protective devices (PPE) for the
ears special for this noise level shall be made
available and a special notice shall be displayed for
that purpose at each one of the entrances.
10 Never remove the isolation or guards of parts with
temperature above 80 °C where the personnel may
inadvertently touch them, until they have cooled down.
11 Never use the machine in an area where there is the
risk of absorption of toxic or flammable vapors.
12 If the work process produces fumes, dust or vibrations,
etc, the necessary precautions should be taken to
eliminate the risk of injury.
13 When using compressed or inert gas to clean the
equipment, do it with caution and wear appropriate
protective devices (at least eye protections).Do not
apply compressed or inert gas on skin, or direct the
air or gas flow to other people. Never use these
substances to remove dirt from your clothes.
14 When washing parts with a cleaning solvent, make
sure the relevant ventilation procedures are complied
with and wear appropriate protective devices, such as
breathing filters, safety goggles, rubber apron and
gloves, etc.
15 Wearing safety shoes should be mandatory in any
workplace and if there is any risk, however small, of
falling objects, the compulsory wearing of a helmet
should be included.
16 If there is any risk of inhalation of dangerous gas,
vapor or dust, respiratory organs should be protected
and, depending on the nature of the danger, eyes and
skin should also be protected.
