Environmental Precautions
General
This section provides general information which can
help to reduce the environmental impacts from the
activities carried out in workshops.
Emissions to air
Many of the activities that are carried out in
workshops emit gases and fumes which contribute to
global warming, depletion of the ozone layer and/or
the formation of photochemical smog at ground
level. By considering how the workshop activities are
carried out, these gases and fumes can be
minimised, thus reducing the impact on the
environment.
Exhaust fumes
Running car engines is an essential part of workshop
activities and exhaust fumes need to be ventilated to
atmosphere. However, the amount of time engines
are running and the position of the vehicle should be
carefully considered at all times, to reduce the
release of poisonous gases and minimise the
inconvenience to people living nearby.
Solvents
Some of the cleaning agents used are solvent based
and will evaporate to atmosphere if used carelessly,
or if cans are left unsealed. All solvent containers
should be firmly closed when not needed and
solvent should be used sparingly. Suitable
alternative materials may be available to replace
some of the commonly used solvents. Similarly,
many paints are solvent based and the spray should
be minimised to reduce solvent emissions.
Refrigerant
It is illegal to release any refrigerants into the
atmosphere. Discharge and replacement of these
materials from air conditioning units should only be
carried out using the correct equipment.
Checklist
Always adhere to the following.
Engines:
ldon't leave engines running unnecessarily;
lminimise testing times and check where the
exhaust fumes are being blown.
Materials:
lkeep lids on containers of solvents;
lonly use the minimum quantity;
lconsider alternative materials;
lminimise over-spray when painting. Gases:
luse the correct equipment for collecting
refrigerants;
ldon't burn rubbish on site.
Discharges to water
Most sites will have two systems for discharging
water: storm drains and foul drains. Storm drains
should only receive clean water, foul drains will take
dirty water.
The foul drain will accept many of the normal waste
waters such as washing water, detergents and
domestic type wastes, but oil, petrol, solvent, acids,
hydraulic oil, antifreeze and other such substances
should never be poured down the drain. If in any
doubt speak to the Water Company first.
Every precaution must be taken to prevent spillage of
oil, fuel, solvents etc. reaching the drains. All
handling of such materials must take place well away
from the drains and preferably in an area with a kerb
or wall around it, to prevent discharge into the drain.
If a spillage occurs it should be soaked up
immediately. Having a spill kit available will make
this easier.
Additional precautions
Check whether the surface water drains are
connected to an oil water separator, this could
reduce the pollution if an incident was to occur. Oil
water separators do need regular maintenance to
ensure effectiveness.
Checklist
Always adhere to the following.
Disposal:
lnever pour anything down a drain without first
checking that it is environmentally safe to do so,
and that it does not contravene any local
regulations or bye-laws;
l have oil traps emptied regularly.
Spillage prevention:
lstore liquids in a walled area;
lmake sure that taps on liquid containers are
secure and cannot be accidentally turned on;
lprotect bulk storage tanks from vandalism by
locking the valves;
ltransfer liquids from one container to another in
an area away from open drains;
lensure lids are replaced securely on containers;
lhave spill kits available near to points of storage
and handling of liquids.

GENERAL INFORMATION
03-9
Joints and Joint Faces
General
Fit joints dry unless specified otherwise.
lAlways use the correct gaskets as specified.
lWhen jointing compound is used, apply in a thin
uniform film to metal surfaces; take care to
prevent jointing compound from entering
oilways, pipes or blind tapped holes.
lIf gaskets and/or jointing compound is
recommended for use; remove all traces of old
jointing material prior to reassembly. Do not use
a tool which will damage the joint faces and
smooth out any scratches or burrs using an oil
stone. Do not allow dirt or jointing material to
enter any tapped holes or enclosed parts.
lPrior to reassembly, blow through any pipes,
channels or crevices with compressed air.
Locking Devices
General
Always replace locking devices with one of the same
design.
Tab washers
Always release locking tabs and fit new locking
washers. Do not re-use locking tabs.
Locking nuts
Always use a backing spanner when loosening or
tightening locking nuts, brake and fuel pipe unions.
Roll pins
Always fit new roll pins of an interference fit in the
hole.
Circlips
Always fit new circlips of the correct size for the
groove.
Keys and keyways
Remove burrs from edges of keyways with a fine file
and clean thoroughly before attempting to refit key.
Clean and inspect key closely; keys are suitable for
refitting only if indistinguishable from new, as any
indentation may indicate the onset of wear.

GENERAL INFORMATION
03-10
Split pins
Always fit new split-pins of the correct size for the
hole in the bolt or stud.
Screw Threads
General
Metric threads to ISO standards are used.
Damaged nuts, bolts and screws must always be
discarded. Cleaning damaged threads with a die or
tap impairs the strength and fit of the threads and is
not recommended.
Always ensure that replacement bolts are at least
equal in strength to those replaced. Castellated nuts
must not be loosened to accept a split-pin, except in
recommended cases when this forms part of an
adjustment.
Do not allow oil or grease to enter blind threaded
holes. The hydraulic action on screwing in the bolt or
stud could split the housing.
Always tighten a nut or bolt to the recommended
torque figure. Damaged or corroded threads can
affect the torque reading.
To check or re-tighten a bolt or screw to a specified
torque figure, first loosen a quarter of a turn, then
retighten to the correct torque figure.
Oil thread lightly before tightening to ensure a free
running thread, except in the case of threads treated
with sealant/lubricant, and self-locking nuts.

GENERAL INFORMATION
03-11
Bolt and Nut Identification
Bolt identification
An ISO metric bolt or screw made of steel and larger
than 6 mm in diameter can be identified by either of
the symbols ISO M or M embossed or indented on
top of the bolt head.
In addition to marks identifying the manufacturer, the
top of the bolt head is also marked with symbols
indicating the strength grade, e.g. 8.8; 10.9; 12.9;
14.9. As an alternative, some bolts and screws have
the M and strength grade symbol stamped on the
flats of the hexagon.Encapsulated bolts and screws
Encapsulated bolts and screws have a micro-
encapsulated locking agent pre-applied to the
thread. They are identified by a coloured section
which extends 360
° around the thread. The locking
agent is released and activated by the assembly
process and is then chemically cured to provide the
locking action.
Unless a specific repair procedure states otherwise,
encapsulated bolts may be re-used providing the
threads are undamaged and the following procedure
is adopted:
lRemove loose adhesive from the bolt and
housing threads.
lEnsure threads are clean and free of oil and
grease.
lApply an approved locking agent.
An encapsulated bolt may be replaced with a bolt of
equivalent specification provided it is treated with an
approved locking agent.
