week over an entire working life.
STEL (Short Term Exposure Limit) - the average
airborne concentration over a 15 minute period which
should not be exceeded at any time during a normal
eight-hour workday.
According to current knowledge these concentrations
should neither impair the health of, nor cause undue
discomfort to, nearly all workers.
Engineering
Controls
Use with good general ventilation. If mists or vapours
are produced local exhaust ventilation should be used.
Respiratory
Protection
If engineering controls are not effective in
controlling airborne exposure then respiratory
protective equipment should be used suitable for
protecting against airborne contaminants. Final choice
of appropriate breathing protection is dependant upon
actual airborne concentrations and the type of
breathing protection required will vary according to
individual circumstances. Expert advice may be
required to make this decision. Reference should be
made to Australian Standards AS/NZS 1715, Selection,
Use and maintenance of Respiratory Protective Devices;
and AS/NZS 1716, Respiratory Protective Devices.
Eye Protection
Safety glasses with side shields, goggles or full-face
shield as appropriate recommended. Final choice of
appropriate eye/face protection will vary according to
individual circumstances i.e. methods of handling or
engineering controls and according to risk assessments
undertaken. Eye protection should conform with
Australian/New Zealand Standard AS/NZS 1337 - Eye
Protectors for Industrial Applications.
Hand
Protection
Wear gloves of impervious material such as Viton,
Nitrile or Silver Shield. Final choice of appropriate
gloves will vary according to individual circumstances
i.e. methods of handling or according to risk
assessments undertaken. Reference should be made to
AS/NZS 2161.1: Occupational protective gloves -
Selection, use and maintenance.
Body
Protection
Wear appropriate clothing including chemical resistant
apron where clothing is likely to be contaminated. It
is advisable that a local supplier of personal
protective clothing is consulted regarding the choice
of material.
