EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin Pain. Blisters.
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Pain. Severe deep burns.
Safety goggles.
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.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING

TRIISOPROPANOLAMINE ICSC: 0592
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE HYGROSCOPIC CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides. The solution in water is a medium strong base. Reacts with strong oxidants and strong acids.

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

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of dust may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES
Boiling point: 305C
Melting point: 45C
Density: 1 g/cm
Solubility in water, g/100 ml at 20C: 83 (good)
Vapour pressure, Pa at 20C: negligible
Flash point: 160C o.c.
Auto-ignition temperature: 320C
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 are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The cards has been partly updated in April 2005. See sections Environmental Data, EU classification.
