Spill kits
Special materials are available to absorb a number of
different substances. They can be in granular form,
ready to use and bought in convenient containers for
storage. Disposal of used spill-absorbing material is
dealt with in 'Waste Management' section.
Land contamination
Oils, fuels and solvents etc. can contaminate any soil
that they are allowed to contact. Such materials
should never be disposed of by pouring onto soil and
every precaution must be taken to prevent spillage
reaching soil. Waste materials stored on open
ground could also leak, or have polluting substances
washed off them that would contaminate the land.
Always store these materials in suitable skips or
other similarly robust containers.
Checklist
Always adhere to the following.
lDon't pour or spill anything onto the soil or bare
ground;
ldon't store waste materials on bare ground, see
'Spillage prevention' list.
Legal compliance
Some sites may have a discharge consent for
effluent discharge to the foul drain for a car wash etc.
It is important to know what materials are allowed in
the drain and to check the results of any monitoring
carried out by the Water Company.
Where paint-spraying operations are carried out it
may be necessary to apply to the Local Authority for
an air emissions licence to operate the plant. If such
a licence is in operation, additional precautions will
be necessary to comply with the requirements, and
the results of any air quality monitoring must be
checked regularly.
Checklist
Always adhere to the following.
lKnow what legal consents and licences apply to
the operations;
lcheck that the emissions and discharges
comply with legal requirements.
Local issues
A number of environmental issues will be of
particular concern to residents and other neighbours
close to the site. The sensitivity of these issues will
depend on the proximity of the site and the layout
and amount of activity carried on at the site.
Noise is a major concern and therefore
consideration should be given to the time spent
carrying out noisy activities and the location of those
activities that can cause excessive noise. Car alarm testing, panel beating, hammering and
other such noisy activities should, whenever
possible, be carried out indoors with doors and
windows shut or as far away from houses as
possible.
Running vehicle engines may be an outside activity
which could cause nuisance to neighbours because
of both noise and smell.
Be sensitive to the time of day when these activities
are carried out and minimise the time of the noisy
operation, particularly in the early morning and late
evening.
Another local concern will be the smell from the
various materials used. Using less solvent, paint
and petrol could help prevent this annoyance.
Local residents and other business users will also be
concerned about traffic congestion, noise and
exhaust fumes, be sensitive to these concerns and
try to minimise inconvenience from deliveries,
customers and servicing operations.
Checklist
Always adhere to the following.
lIdentify where the neighbours who are likely to
be affected are situated;
lminimise noise, smells and traffic nuisance;
lprevent litter by putting waste in the correct
containers;
lhave waste skips emptied regularly.
Use of resource
Another environmental concern is the waste of
materials and energy that can occur in day to day
activities.
Electricity for heating, lighting and compressed air
uses resources and releases pollution during its
generation.
Fuel used for heating, running cars or vans and
mobile plant is another limited resource which
consumes large amounts of energy during its
extraction and refining processes.
Water has to be cleaned, piped to site and disposed
of; all of which creates more potential pollution.
Oil, spares, paint etc., have all produced pollution in
the process of manufacture and they become a
waste disposal problem if discarded.
Checklist
Always adhere to the following.

GENERAL INFORMATION
03-5
Electricity and heating:
lkeep doors and windows closed in the winter;
lswitch off machinery or lights when not needed;
luse energy efficient heating systems;
lswitch off computers and photocopiers when
not needed.
Fuel:
ldon't run engines unnecessarily;
lthink about whether journeys are necessary and
drive to conserve fuel.
Water:
ldon't leave taps and hose pipes running;
lmend leaks quickly, don't be wasteful.
Compressed air:
ldon't leave valves open;
lmend leaks quickly;
ldon't leave the compressor running when not
needed.
Use of environmentally damaging materials:
lcheck whether a less toxic material is available.
Handling and storage of materials:
lhave the correct facilities available for handling
liquids to prevent spillage and wastage as listed
above;
lprovide suitable locations for storage to prevent
frost damage or other deterioration.
Waste Management
One of the major ways that pollution can be reduced
is by the careful handling, storage and disposal of all
waste materials that occur on sites. Legislation
makes it illegal to dispose of waste materials other
than to licensed waste carriers and disposal sites.
This means that it is necessary to not only know what
the waste materials are, but also to have the
necessary documentation and licenses.
Handling and storage of waste
Ensure that waste materials are not poured down the
drain or onto soils. They should be stored in such a
way as to prevent the escape of the material to land,
water or air.
They must also be segregated into different types of
waste e.g. oil, metals, batteries, used vehicle
components. This will prevent any reaction between
different materials and assist in disposal.
Disposal of waste
Disposal of waste materials must only be to waste
carriers who are licensed to carry those particular
waste materials and all the necessary
documentation must be completed. The waste
carrier is responsible for ensuring that the waste is
taken to the correct disposal sites.Dispose of waste in accordance with the following
guidelines.
lFuel, hydraulic fluid, anti-freeze and oil: keep
separate and dispose of to specialist contractor.
lRefrigerant: collect in specialist equipment and
reuse.
lDetergents: safe to pour down the foul drain if
diluted.
lPaint, thinners: keep separate and dispose of
to specialist contractor.
lComponents: send back to supplier for
refurbishment, or disassemble and reuse any
suitable parts. Dispose of the remainder in
ordinary waste.
lSmall parts: reuse any suitable parts, dispose
of the remainder in ordinary waste.
lMetals: can be sold if kept separate from

General Fitting Instructions
Component removal
Whenever possible, clean components and
surrounding area before removal.
lBlank off openings exposed by component
removal.
lImmediately seal fuel, oil or hydraulic lines when
apertures are exposed; use plastic caps or
plugs to prevent loss of fluid and ingress of dirt.
lClose the open ends of oilways exposed by
component removal with tapered hardwood
plugs or conspicuous plastic plugs.
lImmediately a component is removed, place it in
a suitable container; use a separate container
for each component and its associated parts.
lClean bench and provide marking materials,
labels and containers before dismantling a
component.
Dismantling
Observe scrupulous cleanliness when dismantling
components, particularly when brake, fuel or
hydraulic system parts are being worked on. A
particle of dirt or a cloth fragment could cause a
serious malfunction if trapped in these systems.
lBlow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
'O' rings used for sealing are correctly replaced
or renewed, if disturbed during the process.
lUse marking ink to identify mating parts and
ensure correct reassembly. Do not use a centre
punch or scriber to mark parts, they could
initiate cracks or distortion in marked
components.
lWire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
lWire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
lDo not discard a part due for renewal until after
comparing it with a new part, to ensure that its
correct replacement has been obtained.Cleaning components
Always use the recommended cleaning agent or
equivalent. Ensure that adequate ventilation is
provided when volatile degreasing agents are being
used. Do not use degreasing equipment for
components containing items which could be
damaged by the use of this process.
General inspection
All components should be inspected for wear or
damage before being reassembled.
lNever inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an
incipient failure.
lWhen a component is to be checked
dimensionally against recommended values,
use the appropriate measuring equipment
(surface plates, micrometers, dial gauges etc.).
Ensure the measuring equipment is calibrated
and in good serviceable condition.
lReject a component if its dimensions are
outside the specified tolerances, or if it appears
to be damaged.
lA part may be refitted if its critical dimension is
exactly to its tolerance limit and it appears to be
in satisfactory condition. Use 'Plastigauge' 12
Type PG-1 for checking bearing surface
clearances.
