FIRE	Extremely flammable.	NO open flames, NO sparks, and NO smoking.	Powder, water spray, foam, carbon dioxide .
EXPLOSION

EXPOSURE		STRICT HYGIENE!	IN ALL CASES CONSULT A DOCTOR!
•INHALATION	Drowsiness. Unconsciousness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
•SKIN		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES	Pain. Redness.	Safety goggles, or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION		Do not eat, drink, or smoke during work.	Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive gases . Reacts violently with oxidants, strong bases,aluminium,zinc and magnesium. Attacks plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 ppm (skin) A3 (ACGIH 2001).
MAK: 2 (DFG 2000).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes . The substance may cause effects on the central nervous system . Exposure may result in unconsciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
