EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Cough. Laboured breathing. Sore throat. Shortness of breath.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Redness. Skin burns. Pain. Blisters.
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.
Safety spectacles, 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 Diarrhoea. Sore throat. Vomiting. Abdominal pain. Burning sensation. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention. See Notes.

IMPORTANT DATA
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 fumes and gases (ammonia, nitrogen oxides). The substance is a weak base. Reacts with strong oxidants and strong acids. Attacks tin, aluminum, and some steels.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 5 ppm, 15 mg/m; Peak limitation category: I(2); skin absorption (H); Pregnancy risk group: IIc; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour 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 corrosive to the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.
PHYSICAL PROPERTIES
Boiling point: 63C
Melting point: -104C
Relative density (water = 1): 0.7
Solubility in water: miscible
Vapour pressure, kPa at 20C: 18
Relative vapour density (air = 1): 2.52
Flash point: -9C c.c.
Auto-ignition temperature: 378C
Octanol/water partition coefficient as log Pow: 0.74
