| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames.
|
Powder, water spray, foam, carbon dioxide.
|
| EXPLOSION |
|
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
AVOID ALL CONTACT!
|
|
| Inhalation |
Burning sensation. Cough. Sore throat. Symptoms may be delayed (see Notes). Coma.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Refer for medical attention.
|
| Skin |
MAY BE ABSORBED! Pain. Redness. Blisters. Skin burns.
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
|
| Eyes |
Pain. Redness. Severe deep burns. Loss of vision.
|
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.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive fumes including hydrogen chloride and phosgene. Attacks rubber and some forms of plastic. OCCUPATIONAL EXPOSURE LIMITS: TLV (as TWA): 0.02 ppm; 0.21 mg/m^3 A3 (skin) (ACGIH 1997). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The vapour irritates the eyes, the skin and the respiratory tract. The liquid is corrosive. The substance may cause effects on the kidneys. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. May cause genetic damage in humans. | ||

Boiling point: 212°C Melting point: -18°C Relative density (water = 1): 1.68 Solubility in water: none Vapour pressure, Pa at 20°C: 20 Relative vapour density (air = 1): 9.0 |
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 90°C Auto-ignition temperature: 610°C Octanol/water partition coefficient as log Pow: 4.90 | ||
| ENVIRONMENTAL DATA | |||
|
The substance is toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in fish. The substance may cause long-term effects in the aquatic environment.
