TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Water spray. Alcohol-resistant foam. Powder, carbon dioxide.
EXPLOSION Above 38C explosive vapour/air mixtures may be formed.
Above 38C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

Inhalation Cough. Sore throat. Burning sensation. Laboured breathing. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention.
Skin Redness. Pain. Skin burns.
Protective gloves. Protective clothing.
First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
Eyes Redness. Pain. Severe deep burns.
Safety goggles 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 Abdominal pain. Nausea. Vomiting. Shock or collapse. Burning sensation.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING

2-DIMETHYLAMINOETHANOL ICSC: 0654
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH PUNGENT ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic gases, including nitrogen oxides. The substance is a medium strong base. Reacts violently with acids, acid chlorides, oxidants and isocyanates, causing fire and explosion hazard. Attacks copper and its alloys.

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

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 severely irritating to the respiratory tract. The substance is corrosive to the eyes and the skin. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES
Boiling point: 135C
Melting point: -59C
Relative density (water = 1): 0.89
Solubility in water: miscible
Vapour pressure, Pa at 20C: 612
Relative vapour density (air = 1): 3.03
Flash point: 38C c.c.
Auto-ignition temperature: 220C
Explosive limits, vol% in air: 1.6-11.9
Octanol/water partition coefficient as log Pow: -0.55
ENVIRONMENTAL DATA

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. Kalpur-p, Deanol and Liparon are trade names.
