SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 52°C explosive vapour/air mixtures may be formed.
Above 52°C closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE


INHALATION Cough. Laboured breathing. Nausea. Shortness of breath. Sore throat. Vomiting.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
SKIN MAY BE ABSORBED! Redness. skin burns. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
EYES Redness. Pain. Blurred vision.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION Abdominal pain. Diarrhoea (further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water (extra personal protection: A/P2 filter respirator for organic vapour and harmful dust).
Separated from oxidants, acids, acid chlorides, isocyanates. Dry.

PHYSICAL STATE; APPEARANCE:
COLOURLESS HYGROSCOPIC LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On combustion, forms toxic gases (nitrogen oxides). Reacts violently with oxidants, acids, acid chlorides, and isocyanates. Attacks light metals and copper.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV (as TWA): 10 ppm; 48 mg/m3 (skin) (ACGIH 1992-1993).
MAK: 10 ppm; 50 mg/m3; H (1992).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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 substance irritates the eyes, the skin and the respiratory tract. Inhalation of vapour and/or fumes may cause lung oedema (see Notes). The substance may cause effects on the nervous system.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
 Boiling point: 163°C
Melting point: -70°C
Relative density (water = 1): 0.883
Solubility in water: miscible
Vapour pressure, kPa at 20°C: 0.19
Relative vapour density (air = 1): 4.03
 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01
Flash point: 52°C (c.c.)
Auto-ignition temperature: 250°C
Explosive limits, vol% in air: 6.7-11.7
Octanol/water partition coefficient as log Pow: 0.46
ENVIRONMENTAL
DATA
NOTES
Depending on the degree of exposure, periodic medical examination is indicated. 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 are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. The odour warning when the exposure limit value is exceeded is insufficient.
