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.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 85C explosive vapour/air mixtures may be formed.
Above 85C use a closed system, ventilation.

EXPOSURE
STRICT HYGIENE! PREVENT GENERATION OF MISTS!

Inhalation Cough. Headache. Shortness of breath. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Redness. Pain. Skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. Severe deep burns.
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 Abdominal pain. Burning sensation. Shock or collapse.
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
Collect leaking liquid in sealable containers. Cautiously neutralize spilled liquid. Then wash away with plenty of water. (Extra personal protection: filter respirator for organic gases and vapours.)

ETHANOLAMINE ICSC: 0152
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS, VISCOUS, HYGROSCOPIC LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating and on burning producing toxic and corrosive gases including nitrogen oxides. The substance is a medium strong base. Reacts with cellulose nitrate causing fire and explosion hazard. Reacts violently with strong acids and strong oxidants. Attacks copper, aluminium and their alloys, and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: as TWA 3 ppm; as STEL 6 ppm (ACGIH 2002).
MAK: 2 ppm 5.1 mg/m Sh; Peak limitation category: I (2); MAK: class Pregnancy risk group: C (2002)
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, by ingestion and through the skin.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the respiratory tract, the skin and the eyes. Corrosive on ingestion. The vapour is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system. Exposure could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.

Relative vapour density (air = 1): 2.1
Relative density of the vapour/air-mixture at 20C (air = 1): 1.00
Flash point: 85C c.c.
Auto-ignition temperature: 410C
Explosive limits, vol% in air: 5.5-17
Octanol/water partition coefficient as log Pow: -1.31 (estimated)
ENVIRONMENTAL DATA

NOTES
Depending on the degree of exposure, periodic medical examination is indicated. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT take working clothes home.
