TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames. NO contact with oxidants.
Water spray, alcohol-resistant foam, dry powder, carbon dioxide.
EXPLOSION Above 90C explosive vapour/air mixtures may be formed.
Above 90C use a closed system, ventilation.

EXPOSURE


Inhalation Cough. Sore throat. Nausea. Convulsions. Dizziness. Laboured breathing. Pupillary constriction, muscle cramp, excessive salivation. Sweating. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin MAY BE ABSORBED! Skin burns. Pain. Redness. (See Inhalation).
Protective clothing. Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Pain. Redness. Severe deep burns.
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. Burning sensation. Shock or collapse. Abdominal cramps. Diarrhoea. Vomiting. (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING

2-N-DIBUTYLAMINOETHANOL ICSC: 1418
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
Reacts with oxidants. Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001). The substance decomposes on burning producing nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 ppm as TWA; (skin); BEI issued; (ACGIH 2004).
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and 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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes and the skin. The vapour is irritating to the respiratory tract. Corrosive on ingestion. The substance may cause effects on the central nervous system, resulting in convulsions and respiratory failure. Cholinesterase inhibition. Exposure may result in death. Medical observation is indicated. The effects may be delayed.

PHYSICAL PROPERTIES
Boiling point: 222-232C
Melting point: -70C
Relative density (water = 1): 0.9
Solubility in water: at 20C poor
Vapour pressure, kPa at C: 3.4
Relative vapour density (air = 1): 6
Relative density of the vapour/air-mixture at 20C (air = 1): 1.00
Flash point: 90C c.c.
Auto-ignition temperature: 165C
Explosive limits, vol% in air: 0.5-0.9
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
