International Chemical Safety Cards PROPYLAMINE ICSC: 0941 n-Propylamine 1-Aminopropane Propanamine C3H9N / CH3(CH2)2NH2 Molecular mass: 59.1 ICSC #    0941 CAS #     107-10-8 RTECS # UH9100000 UN #        1277 November 24, 1998 Peer reviewed 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. Powder, alcohol-resistant foam, water in large amounts, carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!  •INHALATION Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Redness. Skin burns. Pain. Blisters. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Pain. 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. Headache. 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 STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Remove all ignition sources. Collect leaking liquid in sealable containers. Wash away spilled liquid with plenty of water. (Extra personal protection: chemical protection suit including self-contained breathing apparatus). Fireproof. Separated from strong oxidants, acids, food and feedstuffs. Well closed. Do not transport with food and feedstuffs.

International Chemical Safety Cards PROPYLAMINE ICSC: 0941 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS, HYGROSCOPIC 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 toxic fumes (nitrogen oxides). The substance is a medium strong base, reacts with acids and is corrosive to aluminium and zinc. Reacts violently with oxidants and mercury causing fire and explosion hazard. Reacts violently with many compounds like halogenated hydrocarbons, alcohols, some nitroparaffins. Attacks copper and copper alloys. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached rather 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. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 48°C Melting point: -83°C Relative density (water = 1): 0.7. Solubility in water: miscible Vapour pressure, kPa at 20°C: 32.9 Relative vapour density (air = 1): 2.0 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3 Flash point: below -37°C Auto-ignition temperature: 317°C Explosive limits, vol% in air: 2.0 - 10.4 Octanol/water partition coefficient as log Pow: 0.15 ENVIRONMENTAL DATA N O T E S Transport Emergency Card: TEC (R)-30G31 NFPA Code: H3; F3; R0; ADDITIONAL INFORMATION ICSC: 0941 PROPYLAMINE (C) IPCS, CEC, 1994
