1.5.8 PLANT MAINTENANCE
a. Plant, machinery and structures should be inspected at regular intervals in
accordance with the manufacturer’s recommendations. In the case of plant
which is subject to corrosion, steps should be taken to effect repairs before
corrosion reaches dangerous limits.
b. A planned preventative maintenance system covering shift, daily, weekly and
periodic times should be established for the different types of machine used.
This should include the inspection of all pulleys, drum surfaces and ropes,
and should stipulate their regular cleaning and lubrication. The system should
include a three-part sequence of inspection, thorough examination and
testing. Results of each stage are to be recorded and signed.
c. Cleaning, repair, maintenance, oiling or greasing of machines or the topping
up of fuel tanks should not be carried out whilst a machine is operating.
d. If inspection involves the running of a petrol or diesel engine in an enclosed
space, all doors and windows to the workshop should be opened and even
then, the engine should only be run intermittently to avoid a dangerous build-
up of fumes.
e. All plant should be kept clean by the regular removal of mud and dirt and of
snow and ice in winter, if applicable.
f. When major dismantling of components is necessary, the correct lifting
equipment should always be used and it should be ensured that struts and
chocks are strategically placed as the process continues.
g. The ignition key should always be removed, and a notice placed in such a
prominent position that it cannot be missed, if it is necessary to work
underneath a machine, or to leave it in an incomplete unsafe state.
h. Moving parts of machinery are to be guarded where possible and such
guards should be in position when machinery is in normal operation. Guards
should not be removed except as required for maintenance purposes, in
which case the machine should be immobilised.
i. Lifting machines and tackle should be inspected and tested at set intervals
and certified for the maximum permissible working loads, and these loads
should not be exceeded. Following any major repair, they should be re-
certified before being returned into service. The owner/operator should be
aware of current legislation in force in their own country and comply with all
regulations regarding re-testing of equipment.
j. Electrical installations should be effectively earthed.
k. Electrically operated hand tools, together with leads and earth wires, should
be inspected at regular intervals to ensure that they have been maintained in
good order, and such inspections should be recorded.
l. Trailing cables, except for hand-lamps and small portable tools should be of
a standard equal to BS 708. Pliable armoured cables are preferred.
