Exposure Standards (TWA) is the time-Weighted average airborne concentration over an eight-hour working day, for
a five day working week over an entire working life. According to current knowledge this concentration should neither
impair the health or, cause undue discomfort to, nearly all workers.
STEL (Short Term Exposure Limit)
: the average airborne concentration over a 15 minute period that should not be
exceeded at any time during a normal eight-hour work day.
NOTICE : Absorption through the skin may be a significant source of exposure
Engineering Control Measures
:
Provide sufficient ventilation to keep airborne levels below exposure limit.
Where vapours or mists are generated, particularly in enclosed areas, and natural ventilation is inadequate a
flameproof ventilation system is required
Personal Protective Equipment
:
Eye:
Use chemical safety goggles and/or a full face shield where splashing is possible.
Maintain eye wash fountain and quick-drench facilities in work area.
Hands: Wear impervious protective clothing, including boots, Nitrile, PVC or rubber gloves
(AS2161) gloves, apron or coveralls, as appropriate, to prevent skin contact.
Other:
Chemical-resistant coveralls and safety footwear (AS3765/2210).
Respirator:
If engineering controls are not effective in controlling airborne exposure then respiratory
protective equipment should be used suitable for protecting against airborne
contaminants. Wear an approved respirator suitable for combined particulate and
organic vapours (boiling point >65'C) (AS1715/1716) Where air- filtering respirators are
unsuitable (eg, airborne concentrations are high, risk of oxygen deficiency, confined
space) use appropriate positive pressure breathing apparatus
.
Always wash hands before eating, drinking, smoking or using the toilet.
Wash contaminated clothing and other protective equipment before storage and reuse.

SECTION 10 – STABILITY AND REACTIVITY
Health Effects
No adverse health effects expected if the material is handled in accordance with the Material Safety Data
Sheet. Symptoms that may arise if the material is mishandled are :
Acute Effects
Swallowing:
Ingestion may cause nausea, vomiting, shortness of breath, headache,
gastritis and intoxication. Ingestion of larger amounts may cause narcotic
effects. Minute amounts aspirated into the lungs can produce chemical
pneumonitis with pulmonary injury.
Oral LD50 ( Mineral Turpentine ) > 2000 mg/kg (Rat), Oral LD50 ( Butyl Acetate ) >
10,800 mg/kg (Rat)
Eye:
Vapors cause eye irritation. Splashes cause severe irritation, possible
corneal burns and eye damage.
