TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Alcohol-resistant foam, powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

Inhalation Cough. Sore throat. Shortness of breath. Laboured breathing. Headache. Dizziness. Weakness. Nausea. 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 Redness. Skin burns. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Pain. Redness. Blurred vision. Blue haze and halo. Temporary loss of vision. 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. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Remove all ignition sources. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus.)
Do not transport with food and feedstuffs.

TRIETHYLAMINE ICSC: 0203
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance decomposes on burning producing irritating and toxic gases including nitrogen oxides. The substance is a strong base, it reacts violently with acid and is corrosive to aluminium, zinc, copper and their alloys in the presence of moisture. Reacts violently with strong oxidants causing fire and explosion hazard. Attacks some forms of plastic, rubber and coating.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as TWA) 1 ppm; (as STEL) 3 ppm; (skin), A4; (ACGIH 2002).
MAK: 1 ppm, 4.2 mg/m; (DFG 2002). MAK: class Peak limitation category: I(2); Pregnancy risk group: IIc; (2002)
EU OEL: 2 ppm, 8.4 mg/m (as TWA); 3 ppm, 12.6 mg/m (as STEL); (skin); (EU 2002).
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 very quickly on evaporation of this substance at 20C.

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

PHYSICAL PROPERTIES
Boiling point: 89C
Melting point: -115C
Relative density (water = 1): 0.7
Solubility in water, g/100 ml at 20C: 17 (good)
Vapour pressure, kPa at 20C: 7.2
Relative vapour density (air = 1): 3.5
Relative density of the vapour/air-mixture at 20C (air = 1): 1.2
Flash point: -17C c.c.
Auto-ignition temperature: 230C
Explosive limits, vol% in air: 1.2-8
Octanol/water partition coefficient as log Pow: 1.45
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
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 odour warning when the exposure limit value is exceeded is insufficient.
