Inhalation Burning sensation. Cough. Sore throat. Shortness of breath. See Notes.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin Redness. Pain. Skin burns.
Protective clothing. Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. Severe deep burns.
Safety goggles, 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. Nausea. Vomiting. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
YELLOW TO BROWN LIQUID OR COLOURLESS CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic gases and irritating fumes. Reacts with acid anhydrides, acid chlorides, bases, oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, by ingestion and through the skin.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the skin the respiratory tract and the eyes. Corrosive on ingestion. Inhalation of an aerosol of this substance may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Boiling point: 211.5C
Melting point: 25.4-26C
Density: 0.97 g/cm
Solubility in water, g/100 ml at 25C: 0.79
Vapour pressure, Pa at 20C: 8
Flash point: >112C c.c.
Auto-ignition temperature: 599C
Explosive limits, vol% in air: 1.1-6.4

ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish.
NOTES
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. Card has been partly updated in October 2005.
