MATERIAL SAFETY DATA SHEET
lll PRECAUTIONS FOR USE
Exposure Standards:
A time weighted average (TWA) concentration for an 8 hour day, and 5 day week has not been established by
3
Worksafe Australia for any of the ingredients in this product. There is a blanket recommendation of 10mg/m for
inspirable dusts or mists when limits have not otherwise been established. The nature of this product makes it unlikely
that this level will be approached in normal use. See ingredients section on page 1 of this data sheet.
Engineering Controls:
In industrial situations, concentration values below the TWA value should be maintained. Values may be reduced by
process modification, use of local exhaust ventilation, capturing substances at the source, or other methods. If you
believe air borne concentrations of mists, dusts or vapours are high, you are advised to modify the process or
environment to reduce the problem.
Personal Protection:
Respiratory Protection: A face mask or respirator may be used when the product is being used in dusty or confined
areas. Otherwise it is usually safe to not use respiratory protection. However, there may be other circumstances where
use of a mask or other device is preferred. Use judgement. For help in selecting suitable equipment consult AS1715.
Protective Gloves: Rubber, PVC or other protective gloves are not necessary but are desirable, especially if product is
being used frequently or for lengthy periods.
Eye Protection: Goggles or full face shield should be used when using this product. Failure to do so may result in eye
damage if an accident occurs.
Clothing: Clean overalls should be worn, preferably with an apron.
Safety Boots: Wearing safety boots would be advisory.
Flammability Limits: Does not burn.
Always wash hands before smoking, eating, drinking or using the toilet. Wash contaminated clothing and other
protective equipment before storing or re-using.
