stored in cylinders at press.ures of up to 2000
lb/sq. in. (13,790 kn/m2) and great care
should be taken in handling these cylinders to
avoid mechanical damage to them or to the
valve gear attached. The contents of each
cylinder should be clearly identified by appro-
priate markings.
Cylinders should be stored in well ventilated
enclosures, and protected from ice and snow,
or direct sunlight. Fuel gases (e.g. acetylene
and propane) should not be stored in close
proximity to oxygen cylinders.
Care shou.ld be exercised to prevent leaks
from gas cylinders and lines,· and to avoid
sources of ignition.
Only trained personnel should undertake
work involving gas cylinders.

GENERAL WORKSHOP TOOLS AND
EQUIPMENT
It is essential that all tools and equipment are
maintained in good condition and the correct
safety equipment used where required.
Never use tools or equipment for any purpose
other than that for which they were designed.
Never overload equipment such as hoists,
jacks, axle and chassis stands or lifting slings.
Damage caused by overloading is not always
immediately apparent and may result in a fa-
tal failure the next time that the equipment is
used.
Do not use damaged or defective tools or
equipment, particularly high speed equip-
ment such as grinding wheels. A damaged
grinding wheel can disintegrate without warn-
ing and cause serious injury.
Wear suitable eye protection when using
grinding, chiselling or sand blasting equip-
ment.
Wear a suitable breathing mask when using
sand blasting equipment, working with as-
bestos based materials or using spraying
equipment.

Always keep high pressure equipment in
good condition and regularly maintained, par-
ticularly at joints and unions.
Never direct a high pressure nozzle at the
skin as the fluid may penetrate to the underly-
ing tissue etc. and cause serious injury.
LEGAL ASPECTS
Many laws and regulations make require-
ments relating to health and safety in the use
of materials and equipment in workshops.
Some of these laws which apply in the U.K.
are listed. Similar laws exist fo.r other territo-
ries:-
•
The Factories Act (1961 ).
•
The Asbestos Regulations (1969).
•
Highly Flammable Liquids and Liquified
Petroleum Gases Regulations (1972).
•
Deposit of Poisonous Waste Act (1972).
•
Control of Pollution Act (1974).
•
Health and Safety at Work Act (1974).
•
The
Packaging
and
Dangerous
Substances
(1978).
Labelling
of
Regulations
•
Centro.I of Lead Regulations ( 1981 ).
Workshops should be familiar, in detail, with
these and associated laws and regulations.
Consult local factory inspectorate if in any
doubt.
LUBRICANTS AND GREASES
Avoid all prolonged and repeated contact
with mineral oils, especially used oils. Used
oils contaminated during service (e.g, routine
service change sump oils) are more irritating
and more likely to cause serious effects in-
cluding skin cancer in the event of gross and
prolonged skin contact.
Wash skin thoroughly after work involving oil.
Proprietary hand cleaners may be of value
provided they can be removed from the skin
with water.
Do not use petrol, paraffin or
other solvents to remove oil from the skin.
Lubricants and greases may be slightly irritat-
ing to the eyes.
Repeated or prolonged skin contact should
be avoided by wearing protective clothing if
necessary. Particular care should be taken
