Dry powder, foam, carbon dioxide .
EXPLOSION


EXPOSURE
AVOID ALL CONTACT!

•INHALATION Cough. Shortness of breath. Sore throat. Laboured breathing.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
•SKIN Skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Causes watering of the eyes. 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 Burning sensation. Abdominal pain. Shock or collapse.

PHYSICAL STATE; APPEARANCE:
OILY COLOURLESS TO YELLOW LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing phosgene , or on contact with water producing toxic and corrosive fumes including hydrogen chloride . Attacks many metals in the presence of water or moist air.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


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

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
Lachrymation. The substance is corrosive to the eyes, the skin and the respiratory tract . Corrosive on ingestion. Inhalation of the aerosol may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point (decomposes): above 100°C
Melting point: 0°C
Relative density (water = 1): 1.20
Solubility in water: reaction
Vapour pressure, kPa at 85-87°C: 0.009
Relative vapour density (air = 1): 1
Flash point: 80.0°C c.c.

ENVIRONMENTAL
DATA


N O T E S

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
