2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Harmful if swallowed. Eye
Contact of dust with the eyes may cause mechanical irritation. Skin
Not expected to cause irritation to the skin. Inhaled
Inhalation of dusts may cause irritation to the respiratory tract. 2.2 Health Effects - Chronic
Detailed information about the effects of overexposure in the human being is unavailable. Experience thus far has not provided any example of obvious overexposure with resultant symptoms. Clinical studies of intravenous injection of mice have indicated an effect on the central nervous system.
2.3 First Aid
Swallowed
Never give anything by mouth to an unconscious person. Drink some water. The mouth should be rinsed out several times. Seek medical advice.
Eye
Open the eyelids and rinse out for at least 15 minutes with water. Consult an eye specialist immediately.
Skin

Inhaled
Take the person to fresh air. If there is difficulty in breathing, seek medical advice.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient.
2.6 Toxicity Data

3. PRECAUTIONS FOR USE
3.1 Exposure Standards
No exposure standard has been established for this product.
3.2 Engineering Controls
If dust is generated ensure effective ventilation. Vent waste air only via suitable separators or scrubbers.
3.3 Personal Protection
In case of dust formation use a particle filter respirator. Wear eye goggles and rubber or PVC gloves. Wear general overalls to minimise the possibility of exposure. Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking or using toilet facilities. Avoid contact with skin and eyes and the inhalation of dust.
3.4 Flammability

4.3 Spills and Disposal
Spills
Clean-up personnel should wear full protective clothing including breahting apparatus in dusty conditions.
Examine possibilities for re-utilisation. Package product wastes. Close and label the waste receptacles and, likewise, any uncleaned empty containers. Sweep up spill and reclaim or place in a covered waste disposal container.
Disposal
Dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal facility, preferably by incineration. When uncleaned empty containers are passed on, the recipient must be warned of any possible hazard that may be caused by residues.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Thermal decomposition : highly exothermic reaction from 160 deg C. No thermal decomposition when handled and stored correctly. Hazardous decomposition products include carbon monoxide, carbon dioxide, nitrogen oxides and other toxic gases. In the case of dusty organic products the possibility of a dust explosion must be considered.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. Use equipment/media appropriate to surrounding fire conditions. 5 OTHER INFORMATION
