Chemical Name: 2-Vinylpyridine
Chemical Formula: C7H7N
Molecular Weight: 105.14 g/mol
Concentration: ≥99%
Impurities/Additives: Trace stabilizers such as hydroquinone, included only for safe storage.
Inhalation: Move person to fresh air without delay. Seek medical attention for difficult or labored breathing, cough, or throat irritation.
Skin Contact: Remove contaminated clothing and shoes, rinse skin with plenty of water for at least 15 minutes. Medical attention is necessary if irritation or burns develop.
Eye Contact: Rinse eyes cautiously with water for at least 15 minutes, remove contact lenses if present, and keep eyelids open. Get immediate medical help.
Ingestion: If swallowed, rinse mouth with water and do not induce vomiting. Seek medical care right away. Never give anything by mouth to an unconscious individual.
Notes for Doctors: Treat for chemical exposure, maintain airway and respiration, consider symptomatic and supportive care as necessary.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, or carbon dioxide. Water spray may be necessary to cool containers.
Unsuitable Media: Direct water streams.
Specific Hazards: Vapors may form explosive mixtures with air. Combustion generates toxic gases including nitrogen oxides and carbon oxides.
Special Protective Equipment: Firefighters need full personal protective equipment including chemical-resistant suit and self-contained breathing apparatus.
Advice for Firefighters: Approach from an upwind direction. Prevent run-off into drains and surface water.
Personal Precautions: Use chemical splash goggles, impervious gloves, and suitable protective clothing to avoid skin and eye contact. Restrict access to spill area.
Environmental Precautions: Block entry into sewers, waterways, basements, or confined areas. Collect spilled liquid with inert absorbent material (sand, earth, vermiculite).
Cleanup Methods: Ventilate the area, contain and collect the spillage, dispose of absorbed material in accordance with local regulations. Decontaminate surfaces using appropriate cleaning agents.
Other Instructions: Notify responsible authorities as required.
Precautions for Handling: Ensure proper ventilation at all times during use. Get rid of static electricity by proper grounding. Avoid inhalation, contact with skin and eyes.
Storage Conditions: Store in tightly closed containers in a cool, dry, and well-ventilated place, away from direct sunlight, heat, and incompatible materials such as oxidizers and acids.
Incompatibilities: Avoid sources of ignition, strong acids, oxidizing agents, and peroxides.
Safe Transfer Practices: Use spark-proof tools and explosion-proof equipment, minimize spills and splashes.
Occupational Exposure Limits: No established OSHA or ACGIH exposure limits; minimize exposure by engineering controls.
Engineering Controls: Use local mechanical exhaust. Closed system handling preferred. Emergency eye wash fountains and safety showers easily accessible.
Personal Protective Equipment: Wear chemical splash goggles, impervious gloves (nitrile recommended), lab coat or apron, safety shoes, and where necessary, a respirator approved for organic vapor.
Hygiene Practices: Avoid eating, drinking, and smoking in working areas. Wash hands thoroughly after use.
Environmental Protection: Prevent emissions or leaks into the atmosphere and waterways.
