TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Cough. Dullness. Laboured breathing. Nausea. Shortness of breath. Sore throat. Vomiting.
Ventilation. Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin MAY BE ABSORBED! Redness. Skin burns. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. Blurred vision. Severe deep burns.
Face shield 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 Vomiting. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Use water spray to disperse vapours. Do NOT wash away into sewer. Wash away remainder with plenty of water. Personal protection: complete protective clothing including self-contained breathing apparatus.
Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS OILY FUMING 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 may polymerize under the influence of acid(s) with fire or explosion hazard. May explode on heating. The substance decomposes on heating and on burning producing toxic fumes including nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2005).
MAK: skin absorption (H); Carcinogen category: 2; Germ cell mutagen group: 3B; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. Exposure far above the OEL may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES
Boiling point: 67C
Melting point: -63C
Relative density (water = 1): 0.8
Solubility in water: miscible
Vapour pressure, kPa at 20C: 14.9
Relative vapour density (air = 1): 2.0
Flash point: -4C c.c.
ENVIRONMENTAL DATA

NOTES
Explosive limits are unknown in literature. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
