General Information - Solvents, Sealants and Adhesives
Description and Operation Published: 11-May-2011

WARNING: Always handle all solvents, sealers and adhesives with extreme care. Some contain chemicals or give off
fumes which can be dangerous to health. Always follow the manufacturers instructions. If in doubt about any substance,
particularly a solvent, DO NOT use it.


CAUTION: If in doubt about the suitability of any proprietary solvent or sealer for a particular application, contact the
manufacturer of the product for information regarding storage, handling and application.

The Solvents, Sealers and Adhesives subsection refers to some commonly used chemicals and materials, hazards associated
with their use, and safety measures to be taken.

Adhesives and Sealers

Highly flammable, flammable, combustible – observe No Smoking policy.

Generally should be stored in No Smoking' areas. Cleanliness and tidiness in use should be observed e.g. disposable paper
covering benches; should be dispensed from applicators where possible; containers, including secondary containers, should be
labelled appropriately.

Solvent - based Adhesives/Sealers - See Solvents

Follow manufacturer's instructions.

Water - based Adhesives/Sealers

Those based on polymer emulsions and rubber latexes may contain small amounts of volatile toxic and harmful chemicals. Skin
and eye contact should be avoided and adequate ventilation provided during use.

Hot Melt Adhesives

In the solid state, they are safe. In the molten state they may cause burns and health hazards may arise from the inhalation
of toxic fumes.
Use appropriate protective clothing and a thermostatically controlled heater with a thermal cut - out and adequate extraction.

Resin - based Adhesives/Sealers e.g. Epoxide and Formaldehyde Resin - based

Mixing should be carried out in well ventilated areas, as harmful or toxic volatile chemicals may be released.

Skin contact with uncured resins and hardeners can result in irritation, dermatitis, and absorption of toxic or harmful chemicals
through the skin. Splashes can damage the eyes.
Provide adequate ventilation and avoid skin and eye contact.

Anaerobic, Cyanoacrylate (Super - glues) and other Acrylic Adhesives Many are irritant, sensitizing or harmful to the skin and/or respiratory tract. Some are eye irritants.
Skin and eye contact should be avoided and the manufacturer's instructions followed.
Cyanoacrylate adhesives (super-glues) MUST NOT contact the skin or eyes. If skin or eye tissue is bonded, cover with a clean
moist pad and seek immediate medical attention. Do not attempt to pull tissue apart. Use in well ventilated areas as vapors
can cause irritation to the nose and eyes.
For two - pack systems see Resin - based and Isocyanate Adhesives/Sealers.

Isocyanate (Polyurethane) Adhesives/Sealers

See also Resin - based Adhesives

Individuals suffering from asthma or respiratory allergies should not work with or near these materials as sensitivity reactions
can occur.

Over exposure is irritating to the eyes and respiratory system. Excessive concentrations may produce effects on the nervous
system including drowsiness. In extreme cases, loss of consciousness may result. Long term exposure to vapor concentrations
may result in adverse health effects.
Prolonged contact with the skin may lead to skin irritation and, in some cases, dermatitis.
Splashes entering the eye will cause discomfort and possible damage.
Any spraying should preferably be carried out in exhaust ventilated booths removing vapors and spray droplets from the
breathing zone.
Wear appropriate gloves, eye and respiratory protection.

General Information - Standard Workshop Practices
Description and Operation

Protecting the Vehicle Published: 04-Jul-2014

Always install covers to protect the fenders before commencing work in the engine compartment. Always install the interior
protection kit, wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic
fluid, antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use polythene
sheets in the luggage compartment to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or installing caps.

Vehicle in Workshop

When working on a vehicle in the workshop always make sure that:

The parking brake is applied or the wheels are securely chocked to prevent the vehicle moving forwards or backwards
If the engine is to be run, there is adequate ventilation, or an extraction hose to remove exhaust fumes is installed
There is adequate room to jack up the vehicle and remove the wheels, if necessary
Fender covers are always installed if any work is to be carried out in the engine compartment
The battery is disconnected if working on the engine, underneath the vehicle, or if the vehicle is jacked up


CAUTION: When electric arc welding on a vehicle, always disconnect the generator wiring to prevent the possibility of a
surge of current causing damage to the internal components of the generator.
If using welding equipment on the vehicle, ensure a suitable fire extinguisher is readily available.

Screw Threads

Damaged nuts, bolts and screws must always be discarded. Attempting to recut or repair damaged threads with a tap
or die impairs the strength and fit of the threads and is not recommended.
NOTES:

During certain repair operations, it may be necessary to remove traces of thread locking agents using a tap. Where this
is necessary, the instruction to do so will appear in the relevant operation and it is essential that a tap of the correct size and
thread is used.


New Taptite bolts when used cut their own threads on the first application.

Some bolts are coated with a thread locking agent and unless stated otherwise, they must not be reused. New bolts
having the same part number as the original must always be installed. When nuts or bolts are to be discarded, the
repair operation and relevant torque chart will include an instruction to that effect. Do not use proprietary thread
locking agents as they may not meet the specification required. See also Encapsulated ('Patched') Bolts and Screws.
Always make sure that replacement nuts and bolts are at least equal in strength to those that they are replacing.
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 holes, the hydraulic action resulting from tightening the bolt or stud can split
the housing and also give a false torque reading.
Always tighten a nut, bolt or screw to the specified torque figure, damaged or corroded threads can give a false torque
reading.
Nut and bolt loosening and tightening sequences, where given, must ALWAYS be followed. Distortion of components or
faulty sealing of joints will result if the sequences are not followed. Where an instruction is given to tighten in stages,
these stages must be adhered to; do not attempt to combine stages particularly where certain stages involve
tightening by degrees.
To check or re-tighten a fixing to a specified torque, first loosen a quarter of a turn, then retighten to the specified
torque figure.
Unless instructed otherwise, do not lubricate bolt or nut threads prior to installing.
Where it is stated that bolts and screws may be reused, the following procedures must be carried out:
Check that threads are undamaged.
Remove all traces of locking agent from the threads.

CAUTION: DO NOT use a wire brush; take care that threads are not damaged.
Make sure that threads are clean and free from oil or grease.
Apply the specified locking agent to the bolt threads.
