SECTION 4. FIRST-AID MEASURES
EYES:
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid imme diately.
SKIN：
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
INGESTION:：
Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
INHALATION：
Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
NOTES FOR PHYSICIAN
Treat symptomatically and supportively.
SECTION 5. FIRE FIGHTING MEASURES
FLAMMABILITY: Flammable!
FLASH POINT：Not available..
AUTOIGNITION TEMPERATURE: Not available.
EXPLOSION LIMITS, LOWER: Not available.
EXPLOSION LIMITS, UPPER: Not available.
EXTINGUISHING MEDIA：Use water spray to cool fire-exposed containers. For large fires, use water spray, fog or regular foam. Contact professional fire-fighters immediately. For small fires, use dry chemical, carbon dioxide, sand, earth, water spray or regular foam. Cool containers with flooding quantities of water until well after fire is out.
GENERAL INFORMATION：As in any fire, wear a self-contained breathing apparatus in pressuredemand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Dust can be an explosion hazard when exposed to heat or flame. Flammable solid. May burn rapidly with flare burning effect. May re-ignite after fire is extinguished. Containers may explode when heated. Risk of explosion if heated under confinement.
SECTION 6. ACCIDENTAL RELEASE MEASURES
PERSONAL PRECAUTIONS: Use proper personal protective equipment as indicated in Section 8.
SPILLS AND LEAKS: Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Scoop up with a nonsparking tool, then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation.
ENVIRONMENTAL PRECAUTIONS: No data.
SECTION 7. HANDLING AND STORAGE
HANDLING：
Wash thoroughly after handling. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
STORAGE：
Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well -ventilated area away from incompatible substances.
HYGIENE PRACTICES：
No data.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS：
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels.
EYES: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
SKIN AND CLOTHING: Wear appropriate protective gloves to prevent skin exposure. Wear appropriate protective clothing to prevent skin exposure.
RESPIRATORS：Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
OTHER PROTECTIVE：
No data.
