ll HEALTH HAZARD DATA
Health Effects:
No specific data is available for the product for chronic exposure symptoms. The ingredients are not listed as
carcinogenic in Worksafe鈥檚 document 鈥淓xposure Standards for Atmospheric Contaminants in the Occupational
Environment鈥? (May 1995).
Acute Effects:
Swallowed: Data suggests that this product should present no significant problems.
Eye: This product is mildly irritating to the eyes. It is likely to cause mild discomfort such as watering and redness of the
eyes. However, this should quickly disappear once exposure is over.
Skin: This product may be mildly irritating to skin. However, it is unlikely to cause any more than mild transient
discomfort. It is also unlikely to cause any lasting effects.
Inhalation: Data indicates that this product may be irritating if inhaled. May lead to minor discomfort which should
quickly disappear once exposure has ceased.
First Aid:
If poisoning occurs, contact a Doctor or Poisons Information Centre. Phone 13 1126 from anywhere in Australia.
If swallowed, do NOT induce vomiting. Give a glass of water.
Eyes: If product gets in eyes, wash material from them with running water. If they begin watering or reddening, take
special care in washing thoroughly.
Skin: If product gets on skin, thoroughly wash contacted areas. No further measures should normally be required
unless irritation is noticed. If irritation persists, seek medical attention.

MATERIAL SAFETY DATA SHEET
Inhalation: No first aid measures normally required. However, if vapours or dusts have been inhaled, and irritation has
developed, remove to fresh air and observe until recovered. If irritation becomes painful or persists more than about 30
minutes, seek medical advice.
Advice to Doctor: Treat symptomatically. Note the nature of this product.
lll PRECAUTIONS FOR USE
Exposure Standards:
A time weighted average (TWA) has been established for Sodium molybdate, present in significant quantities in this
product. This value is 5mg/m3. The corresponding STEL level is "not set". The STEL (Short Term Exposure Limit) is an
exposure value that should not be exceeded for more than 15 minutes and should not be repeated for more than 4
times per day. There should be at least 60 minutes between successive exposures at the STEL. The exposure value at
the TWA is the average airborne concentration of a particular substance when calculated over a normal 8 hour working
day for a 5 day working week. 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: The use of a dust or vapour mask is suggested when this product is being used, especially if in
confined or dusty spaces. For help in selecting suitable equipment, consult AS/NZS 1715.
Protective Gloves: Impermeable protective gloves should be worn when you are using this product, to prevent irritation.
For help in selecting suitable equipment, consult AS 2161.
Eye Protection: Protective eyewear is suggested when using this product. It is always prudent to use protective
eyewear. Consult AS1336 and AS/NZS 1337 for advice on Industrial Eye Protection.
Clothing: This product is essentially safe to use without special protective clothing. However, its use is recommended
as a good industrial practice. Consult AS2919 for advice on Industrial Clothing.
Safety Boots: Wearing safety boots in industrial situations is advisory. Consult AS/NZS2210 for advice on Occupational
Protective Footwear.
Always wash hands before smoking, eating or using the toilet. Wash contaminated clothing and other protective
equipment before storing or re-using.
lV SAFE HANDLING INFORMATION
Storage & Transport
No special storage and transport requirements. This product has no UN classification. Not a Scheduled Poison.
