Description of necessary measures according to routes of exposure.

Swallowed
Rinse mouth with water and give plenty of water to drink. Do NOT induce vomiting. Seek immediate medical attention and show this container or label.
Eye
In case of eye contact, immediately rinse with clean water for 20-30 minutes. Seek medical advice.
Skin
Wash skin thoroughly with mild soap and water. Remove contaminated clothing and shoes. Wash clothing before re-using. Seek medical attention if ill effect or irritation develops.

5. FIRE FIGHTING MEASURES

Extinguishing Media
In case of fire, appropriate extinguishing media include sand, carbon dioxide, or dry chemical powder. Unsuitable extinguishing media include water. In the presence of water, contact with metals may produce hydrogen which may form explosive mixtures with air.
Hazards from Combustion Products
Non-combustible solid. Incompatible with acids and sources of ignition. In the presence of water, contact with metals may produce hydrogen which may form explosive mixtures with air. Contact with acids release fluoric acid. Hazardous decomposition products include Fluoric acid.
Special Protective Precautions and Equipment for Fire Fighters
Fire fighters should wear a positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, boots and gloves) or chemical splash suit. Clear fire area of all non-emergency personnel. Stay upwind. Keep out of low areas. Eliminate ignition sources. Move fire exposed containers from fire area if it can be done without risk. Do NOT allow fire fighting water to reach waterways, drains or sewers. Store fire fighting water for treatment.
Flammability Conditions
Product is a non-flammable solid.

6. ACCIDENTAL RELEASE MEASURES

Emergency Procedures
Personnel involved in the clean up should wear full protective clothing as listed in section 8. Evacuate all unnecessary personnel. Eliminate all sources of ignition. Increase ventilation. Avoid generating dust. Stop leak if safe to do so. Isolate the danger area. Do NOT let product reach drains or waterways. If product does enter a waterway, advise the Environmental Protection Authority or your local Waste Management. Use clean, non-sparking tools and equipment. Do NOT contaminate. Keep combustibles away from spilled material. Do NOT Touch damaged containers or spilled material unless wearing appropriate protective clothing as listed in section 8.
Methods and Materials for Containment and Clean Up
Contain and sweep/shovel up spills with dust binding material or use an industrial vacuum cleaner. Transfer to a suitable, labelled container and dispose of promptly as hazardous waste.

7. HANDLING AND STORAGE

Precautions for Safe Handling
Ensure an eye bath and safety shower are available and ready for use Observe good personal hygiene practices and recommended procedures. Wash thoroughly after handling. Do not breathe dust. Avoid all contact with this substance. Wash hands plentifully and other exposed areas with water after handling. Remove contaminated clothing and shoes. Wash clothing before re- using. Packagings, even those that have been emptied, will retain product residue. Always obey safety warnings and handle empty packagings as if they were full. Avoid prolonged or repeated exposure.
Conditions for Safe Storage (Including Any Incompatibles)
Store in a cool, dry, well-ventilated area. Keep containers tightly closed when not in use. Inspect regularly for deficiencies such as damage or leaks. Protect against physical damage. Store away from incompatible materials as listed in section 10. Keep away from food, drink and animal feeding stuffs. This product has a UN classification of 2674 and a Dangerous Goods Class 6.1 (Toxic) according to The Australian Code for the Transport of Dangerous Goods By Road and Rail.
Container Type
Container type/packaging must comply with all applicable local legislation. Store in original packaging as approved by manufacturer.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

National Exposure Standards
No exposure standard has been established for this product by the Australian Safety and Compensation Council (ASCC). However, the exposure standard for dust not otherwise specified is 10mg/m3 (for inspirable dust) and 3mg/m3 (for respirable dust). NOTE: 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. These exposure standards are guides to be used in the control of occupational health hazards. All atmospheric contamination should be kept to as low a level as is workable. These exposure standards should not be used as fine dividing lines between safe and dangerous concentrations of chemicals. They are not a measure of relative toxicity.
Biological Limit Values
No information available on biological limit values for this product.
Engineering Controls
A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Protection
RESPIRATOR: Wear an approved air-supplied respirator where vapours/dusts are formed and engineering controls are inadequate (AS1715/1716). EYES: Chemical safety goggles and face shield (AS1336/1337). HANDS: Rubber gloves (AS2161). CLOTHING: Rubber apron, chemical suit and rubber footwear (AS3765/2210).
