5. FIRE-FIGHTING MEASURES
Extinguishing Media
Water fog or fine spray.
Carbon dioxide.
Dry chemical.
Hazardous Combustion Products
During a fire, smoke may contain the original material in addition to
unidentified toxic and/or irritating compounds.
Combustion products include: Carbon oxides. Hydrogen chloride. Nitrogen
oxides.
Protection of Firefighters
Wear protective clothing and use self-contained breathing apparatus.
Additional Information
Dusts at sufficient concentrations can form explosive mixtures with
air. Keep containers cool by spraying with water. Contain runoff to
prevent entry into water or drainage systems. Work upwind of any spill.
Avoid breathing smoke.
________________________________________________________________________
6. ACCIDENTAL RELEASE MEASURES
Personal Precautions
Wear appropriate safety clothing and eye/face protection (see Section
8). Remove contaminated clothing immediately, wash skin area with soap
and water, and launder clothing before reuse.
Environmental Precautions
Do not wash into sewers or into any body of water. Advise water
authority if spillage has entered water course or drainage system.
Methods of Cleaning Up
Spills should be cleaned up immediately using care to minimise
generation of airborne dust. Collect all waste material and place in
closable marked containers. For large spills, barricade area and
consult manufacturer. If further assistance is required, telephone the
emergency contact number.

7. HANDLING AND STORAGE
Handling
Use good personal hygiene. Do not consume or store food in the work
area. Avoid dust build-up. Proper ventilation is recommended to control
dust formation. Transfer equipment should be grounded and bonded to
avoid static charge and spark-proof equipment should be used. Wash
hands and exposed skin before eating, drinking or smoking and after
work.
Storage
Product should be stored in compliance with local regulations. Store in
a cool, dry, well-ventilated place in the original container. Do not
store near food, drink, animal feeding stuffs, pharmaceuticals,
cosmetics or fertilisers. Keep out of reach of children.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Guidelines
Active ingredient: Dow AgroSciences recommendation is 0.1 mg/m3.
Engineering Controls
Provide general and/or local exhaust ventilation to control airborne
levels below the exposure guidelines.
Respiratory Protection
For most conditions, no respiratory protection should be needed.
However, when airborne exposure guidelines and/or comfort levels may be
exceeded use an approved air-purifying respirator.
For emergency conditions, use an approved positive-pressure self-
contained breathing apparatus.
Hand/Skin Protection
For brief contact, no precautions other than clean body-covering
clothing and chemical resistant gloves should be needed. When prolonged
or frequently repeated contact could occur, use protective clothing
impervious to this material.
For emergency conditions: Use protective clothing impervious to this
material. Selection of specific items will depend on operation.
Eye/Face Protection
Safety glasses should be sufficient for most operations; however, for
dusty operations wear chemical goggles.

harmful amounts. Essentially non-irritating to skin.
Sensitisation
Non-sensitising to guinea pig skin.
Eye Contact
May cause slight transient (temporary) eye irritation.
Inhalation
No adverse effects anticipated by this route of exposure incidental to
proper handling.

16. OTHER INFORMATION
Category 3 carcinogens, according to EC criteria, are substances which
cause concern for man owing to possible carcinogenic effects, but in
respect of available information is not adequate for making a
satisfactory assessment. There is some evidence from appropriate animal
studies, but this is insufficeint to place the substance in EC category
2 - substances which should be regarded as if they are carcinogenic to
man.
