Put in a comfortable body position, ease breathing and call a doctor. After inhalation: Fresh air must be provided. Call a doctor. After eye contact: Rinse eye immediately with plenty of water, at least 15 minutes. Avoid strong stream of water due to the risk of mechanical damage to the cornea. Immediately call a doctor. After skin contact: Take off contaminated clothing. Rinse skin with plenty of water. In case of irritation consult a physician. After ingestion: Rinse the mouth with water. Do not induce vomiting. Call a doctor. 5. FIRE FIGHTING MEASURES Firefighting media: Dry powder and foam extinguishers, carbon dioxide. Firefighting media prohibited in safety reasons: Not specified Hazardous decomposition products: Hard flammable liquid. Vapours form explosive mixture in contact with oxygen at high temperature. In case of fire it generates hazardous decomposition products. Special protective equipment for fire-fighters: Fire can produce harmful substances for human health. Apply a gas-tight protective clothing and breathing apparatus (breathing apparatus complete with mask). 6. ACCIDENTAL RELEASE MEASURES Individual precautions: Avoid contact with skin and eyes. Provide air exchange (ventilation). Follow the rules of safety and health at work with chemical substances. Use personal protective equipment as indicated in Section 8. Environmental precautions: In case of failure do not allow the release to the environment. Prevent product from entering sewers, groundwater, soil. Cleaning methods: Secure drain pits; use water spray to disperse vapours; remove sources of ignition (extinguish open fire, announce smoking prohibition and use of ignition tools prohibition); if possible eliminate leak (stop liquid inflow, seal and place damaged packaging in a sealed protective container); in case of major leak, bank the area of liquid accumulation and pump out the gathered liquid; cover the small quantity of leaked liquid with non-flammable absorbent material; gather into a locked container. Rinse the contaminated area with water.
