International Chemical Safety Cards ETHYLAMINE ICSC: 0153 Ethanamine Aminoethane C2H5NH2 / C2H7N Molecular mass: 45.1 (cylinder) ICSC #    0153 CAS #     75-04-7 RTECS # KH2100000 UN #        1036 EC #         612-002-00-4 October 09, 2002 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with dry powder, carbon dioxide. EXPLOSION Gas/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. EXPOSURE 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 ON CONTACT WITH LIQUID: FROSTBITE. Cold-insulating gloves. Protective clothing. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.  •EYES Redness. Pain. Blurred vision. Safety goggles, 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 Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. Remove all ignition sources. NEVER direct water jet on liquid. (Extra personal protection: complete protective clothing including self-contained breathing apparatus.) Fireproof. Cool.

No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards ETHYLAMINE ICSC: 0153 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS COMPRESSED LIQUEFIED GAS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The gas is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance decomposes on burning producing toxic gases including nitrogen oxides . The solution in water 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); MAK: class Pregnancy risk group: IIc (2002). EU OEL: 5 ppm; 9.4 mg/m³; (EU 2002). OSHA PEL: TWA 10 ppm (18 mg/m3) NIOSH REL: TWA 10 ppm (18 mg/m3) NIOSH IDLH: 600 ppm ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: On loss of containment, a harmful concentration of this gas in the air will be reached very quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the eyes and the respiratory tract . Rapid evaporation of the liquid may cause frostbite. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 16.6°C Melting point: -81°C Relative density (water = 1): 0.7 (liquid) Solubility in water: miscible Vapour pressure, kPa at 20°C: 121 Relative vapour density (air = 1): 1.55 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.66 Flash point: -17°C c.c. Auto-ignition temperature: 385°C Explosive limits, vol% in air: 3.5-14 Octanol/water partition coefficient as log Pow: -0.27/-0.08 (calculated) ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Ethylamine is available commercially also in the form of 50-70% aqueous solution (UN number: 2270). Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
