Inhalation: Move outside to fresh air right away. Seek medical attention if you feel dizzy or trouble breathing shows up.
Skin Contact: Remove set clothing and flush affected area with running water for 15 minutes. Check for chemical burns. Get a medical check-up.
Eye Contact: Pull apart eyelids and wash eyes under running water for several minutes. Contact emergency services as quickly as possible.
Ingestion: Do not force vomiting. Rinse out mouth, drink a glass of water, and look for medical help instantly.
Extinguisher Type: Foam, dry chemical, CO2, do not use a direct water stream.
Hazards in Fire: Develops toxic fumes—carbon oxides, nitrogen oxides, and possibly amines in smoke.
Special Equipment: Full gear with self-contained breathing apparatus needed.
Instructions: Evacuate area. Use flooding amounts of extinguishing medium for large fires. Cool containers with water spray from safe distance.
Personal Precautions: Put on appropriate gloves, goggles, and chemical apron before approaching spill. Provide good ventilation.
Spill Handling: Contain with dikes to prevent spread. Use inert absorbents like sand to pick up spill. Shovel into chemical waste containers.
Clean-Up: Scrub area with soap and water after material is removed. Dispose cleanup materials according to regulations.
Environmental Precautions: Keep runoff out of drains and watercourses.
Handling: Operate in well-ventilated setting or chemical fume hood. Avoid breathing vapor and direct skin contact. Seal containers tightly after every use.
Storage: Keep cool and away from sunlight or sources of ignition. Store in corrosion-resistant containers away from oxidizers, acids, or bases. Lock up to fend off unauthorized access.
Incompatibilities: Do not store with strong acids, oxidizers, or open flames.
Exposure Limits: OSHA/ACGIH has not specified limits for alpha-pyrrolidine, but treat as hazardous.
Engineering Controls: Fume hoods, exhaust fans, proper airflow to reduce vapor exposure.
Personal Protection: Wear chemical splash goggles, nitrile or neoprene gloves, long-sleeved lab coat. In high vapor conditions, use organic vapor respirator. No open food or drinks nearby.
Appearance: Colorless to pale yellow liquid

Melting Point: -63 °C (-81 °F)
Flash Point: 15 °C (59 °F)
Solubility: Easily dissolves in water and most organic solvents
Vapor Density: 2.5 (air = 1)
pH: Basic, forms alkaline solution in water
Vapor Pressure: High at room temperature
Chemical Stability: Stable in closed container at normal temperatures.
Hazardous Reactions: Reacts strongly with oxidizing agents and acids, giving off heat and toxic gases.
Hazardous Decomposition: Nitrogen oxides, carbon monoxide, carbon dioxide, under fire conditions.
Conditions to Avoid: Do not allow contact with moisture or expose to open flames.
Routes of Exposure: Inhalation, ingestion, skin and eye absorption.
Acute Toxicity: LD50 (oral, rat) ~300 mg/kg. Inhalation causes respiratory distress.
Chronic Effects: May damage liver, kidneys, central nervous system upon repeated exposure.
Other Data: Strong irritant, may cause chemical burns. Rapid onset of symptoms, seek medical attention for any exposure.
Toxicity to Aquatic Life: Highly toxic to fish, aquatic invertebrates and plants in even minor concentrations.
Persistence and Degradability: May not break down quickly in water. Binds to soil and may affect local biology.
Bioaccumulation: No strong accumulation in aquatic organisms predicted, but use caution.
Other Information: Do not allow chemical to reach surface water, groundwater, or sewage systems.
Waste Treatment: Collect liquid and solid waste in sealed, labeled drums for hazardous chemical processing.
Disposal Methods: Follow local and national laws for hazardous chemical waste. Incineration at approved facility is recommended.
Container Handling: Rinse empty containers with plenty of water before disposal. Never reuse for food or drink.
