PYRROLIDINE ICSC: 1315 Azacyclopentane Pyrrole, tetrahydro C4H9N Molecular mass: 71 ICSC #    1315 CAS #     123-75-1 RTECS # UX9650000 UN #        1922 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. Foam, powder, carbon dioxide. Explosion Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. Prevent build-up of electrostatic charges (e.g., by grounding). In case of fire: keep drums, etc., cool by spraying with water. Exposure PREVENT GENERATION OF MISTS!  •Inhalation Burning sensation. Convulsions. Cough. Headache. Nausea. Sore throat. Vomiting. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •Skin Redness. Skin burns. Pain. Blisters. Protective gloves. Protective clothing. Rinse skin with plenty of water or shower. Refer for medical attention.  •Eyes Redness. Pain. Blurred 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 Convulsions. Sore throat. Vomiting. (See Inhalation). Do not eat, drink, or smoke during work. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: chemical protection suit including self-contained breathing apparatus. Fireproof. Separated from strong oxidants, acids. Well closed. Unbreakable packaging; put breakable packaging into closed unbreakable container. UN Hazard Class: 3 UN Subsidiary Risks: 8 UN Packing Group: II PYRROLIDINE ICSC: 1315 Important Data Physical State; Appearance: COLOURLESS TO YELLOW LIQUID , WITH PUNGENT 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 including nitrogen oxides The substance is a strong base, it reacts violently with acid and is corrosive. Reacts violently with oxidants . Occupational Exposure Limits: TLV not established. MAK: IIb (not established but data is available); skin absorption (H); (DFG 2004). Routes of Exposure: The substance can be absorbed into the body by inhalation and by ingestion. Inhalation Risk: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. Effects of Short-Term Exposure: The substance is irritating to the respiratory tract , is corrosive to the eyes and the skin. The substance may cause effects on the nervous system . Effects of Long-Term or Repeated Exposure: Physical Properties Boiling point: 89°C Melting point: -63°C Relative density (water = 1): 0.85 Solubility in water: miscible Vapour pressure, kPa at 39°C: 1.8 Relative vapour density (air = 1): 2.45 Flash point: 3°C Explosive limits, vol% in air: 2.9-13.0 Octanol/water partition coefficient as log Pow: 0.46 Environmental Data N O T E S Card has been partly updated in April 2005.
