International Chemical Safety Cards TRIETHYLAMINE ICSC: 0203 TRIETHYLAMINE N,N-Diethylethanamine C6H15N/(C2H5)3N Molecular mass: 101.2 CAS # 121-44-8 RTECS # YE0175000 ICSC # 0203 UN # 1296 EC # 612-004-00-5 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 STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN! INHALATION Cough. Sore throat. Shortness of breath. Laboured breathing. Headache. Dizziness. Weakness. Unconsciousness. Nausea. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Refer for medical attention. SKIN MAY BE ABSORBED! 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. Diarrhoea. Shock or collapse. Vomiting (further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus). Fireproof. Separated from strong oxidants, strong acids, food and feedstuffs. Do not transport with food and feedstuffs.

International Chemical Safety Cards TRIETHYLAMINE ICSC: 0203 I M P O R T A N T D A T A 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 heating or on burning producing toxic and irritating gases including nitrogen oxides. The substance is a strong base, it reacts violently with acids 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 plastics, rubber and coatings. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: 10 ppm; 41 mg/m3 STEL: 15 ppm; 62 mg/m3 (ACGIH 1993-199?). 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 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the substance may cause lung oedema (see Notes). The substance may cause effects on the central nervous system. PHYSICAL PROPERTIES Boiling point: 89°C Melting point: -115°C Relative density (water = 1): 0.7 Solubility in water, g/100 ml at 20°C: 17 (good) Vapour pressure, kPa at 20°C: 7.2 Relative vapour density (air = 1): 3.5 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2 Flash point: -17°C c.c. Auto-ignition temperature: 230°C Explosive limits, vol% in air: 1.2-8 Octanol/water partition coefficient as log Pow: 1.45

ENVIRONMENTAL DATA
N O T E S
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 spray, 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.
