INTRODUCTION
Brief exposure to high concentrations of vapors or mists will cause eye and throat irritation, drowsiness, dizziness,
headaches and in the worst circumstances, unconsciousness.
Repeated or prolonged exposures to excessive but lower concentrations of vapors or mists, for which theremight not
be adequatewarning indications, can cause more serious toxic or harmful effects.
Aspiration into the lungs (e.g. through vomiting) is the most serious consequence of swallowing.
Avoid splashes to the skin, eyes and clothing. Wear protective gloves, goggles and clothing if necessary.
Ensure good ventilation when in use, avoid breathing fumes, vapors and spray mists and keep containers tightly
sealed. Do not use in confined spaces.
When the spraying material contains solvents, e.g. paints, adhesives, coatings, use extraction ventilation or personal
respiratory protection in the absence of adequate general ventilation.
Do not apply heat or flame except under specific and detailed manufacturers instructions.
Sound insulation
See fibre insulation, foams.
Spot welding
See welding.
Suspended loads
There is always a danger when loads are lifted or suspended. Never work under an unsupported suspended or raised
load, e.g. jacked up vehicle, suspended engine, etc.
Always ensure that lifting equipment such as jacks, hoists, axle stands, slings, etc. are adequate and suitable for the
job, in good condition and regularly maintained.
Never improvise lifting tackle.
Underseal
See corrosion protection.
Welding
See fire, electric shock, gas cylinders.
Welding processes include resistance welding (spot welding), arc welding and gas welding.
Resistance welding
This process may cause particles of molten metal to be emitted at high velocity and the eyes and skin must be pro-
tected.
Arc welding
This process emits a high level of ultraviolet radiation which may cause eye and skin burns to the welder and to other
persons nearby. Gas-shielded welding processes are particularly hazardous in this respect. Personal protection must
be worn, and screens used to shield other people.
Metal spatter will also occur and appropriate eye and skin protection is necessary.
The heat of the welding arc will produce fumes and gases from the metals being welded and from any applied coatings
or contamination on the surfaces being worked on. These gases and fumes may be toxic and inhalation should
always be avoided. The use of extraction ventilation to remove the fumes from the working area may be necessary,
