Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Water spray, dry powder, alcohol-resistant foam. 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 PREVENT GENERATION OF MISTS! STRICT HYGIENE!  •INHALATION Cough. Laboured breathing. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. Pain. Protective clothing. Protective gloves. Rinse skin with plenty of water or shower. Refer for medical attention. Remove contaminated clothes.  •EYES Redness. Pain. Blurred vision. 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. 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 STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. Remove all ignition sources. Cautiously neutralize spilled liquid. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: filter respirator for organic gases and vapours.) Fireproof. Cool. Well closed. Separated from acids, oxidants .

International Chemical Safety Cards ETHYLAMINE (50-70% aqueous solution) ICSC: 1482 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS SOLUTION IN WATER , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance is a strong base, it reacts violently with acid and is corrosive. Reacts violently with strong oxidants and organic compounds causing fire and explosion hazard. Attacks many non-ferrous metals and plastic. OCCUPATIONAL EXPOSURE LIMITS: TLV: 5 ppm as TWA; 15 ppm as STEL; (skin) (ACGIH 2002). MAK: 5 ppm, 9.4 mg/m³; Peak limitation category: I(2); Pregnancy risk group: IIc; (DFG 2002). EU OEL: 5 ppm, 9.4 mg/m³; (EU 2002). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air will on evaporation of this substance at 20°C be reached very quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes , the skin and the respiratory tract . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 17°C Melting point: -81°C Relative density (water = 1): 0.81 Vapour pressure, kPa at 2°C: 53.3 Relative vapour density (air = 1): 1.6 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3 Flash point: -18°C c.c. Auto-ignition temperature: 385°C Explosive limits, vol% in air: 3.5-14 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S See ICSC 0153 Ethylamine, gas in a cylinder. All physical properties are for 70% solution.
