CN101 - Maintenance
Dusts:
Powder, dusts or clouds may be irritant, harmful or toxic. Avoid breathing dusts from
powdery chemical materials or those arising from dry abrasion operations.
Wear respiratory protection in accordance with the requirement of the Health and Safety
Acts.
Electric shocks:
When working on electrical systems, remove watches, bracelets and rings as these can
conduct electricity and cause shorts and/or burns.
Electric shocks can result from the use of faulty electrical equipment or from the misuse
of equipment even in good condition.
Ensure that electrical equipment is maintained in good condition and frequently inspected
and tested.
Ensure that flexes, cables, plugs and sockets are not frayed, kinked, cut, cracked or
otherwise damaged.
Ensure that electrical equipment is protected by the correct rated fuse and if used outside
an earth-leakage circuit breaker is used.
Never misuse electrical equipment and never use equipment that is in any way faulty. The
results could be fatal.
Use reduced voltage equipment (110 or 24 volt) for inspection and working lights where
possible.
Ensure that the cables of mobile electrical equipment cannot be trapped and damaged
such as in a vehicle hoist, trolley jacks, etc.
Use air operated mobile equipment where possible in preference to electrical equipment.
Exhaust fumes:
These contain asphyxiating, harmful and toxic chemicals and particles such as carbon
oxides, nitrogen oxides, aldehydes, leads and aromatic hydrocarbons.
Engines should only be run under conditions of adequate extraction or general ventilation
and not in confined spaces.
NB :
Catalyst exhausts/silencers can run at extremely high temperatures.
Fire and welding:
Observe strict fire safety when storing and handling flammable materials or solvents,
particularly near electrical equipment or welding processes.
Disconnect battery, microprocessors, etc. before commencing welding. Failure to observe
this could cause failure of components.
Ensure before using electrical or welding equipment that there is no fire hazard present.
Have a suitable fire extinguisher available when using welding or heating equipment.
Special precautions must be taken before any welding or cutting takes place on vessels
which have contained combustible materials, e.g. fuel tanks.
The sound insulation foam used on the equipment must be removed if any welding is to
be carried out in that area of the machine.
