COMPOSITION/INFORMATION ON INGREDIENTS Substance/mixture:Substance Components:2-Methyl-2-butenenitrile Percent:>70.0%(GC) CAS Number:4403-61-6 Synonyms:2-Cyano-2-butene , 1-Methyl-1-propenyl Cyanide Chemical Formula:C5H7N Section4. FIRST AID MEASURES Inhalation:Remove victim to fresh air and keep at rest in a position comfortable for breathing. Call a POISON CENTER or doctor/physician. Skin contact:Remove/Take off immediately all contaminated clothing. Gently wash with plenty of soap and water. Call a POISON CENTER or doctor/physician. Eye contact:Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If eye irritation persists: Get medical advice/attention. Ingestion:Immediately call a POISON CENTER or doctor/physician. Rinse mouth. Protection of first-aiders:A rescuer should wear personal protective equipment, such as rubber gloves and air- tight goggles. Section5. FIRE-FIGHTING MEASURES Suitable extinguishingDry chemical, foam, carbon dioxide. media: Unsuitable extinguishing Water (It may scatter and spread fire.) media: Specific hazards arising Take care as it may decompose upon combustion or in high temperatures to from the chemical:generate poisonous fume. Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place. In case of fire in the surroundings: Keep containers cool by spraying with water. Eliminate all ignition sources if safe to do so. When extinguishing fire, be sure to wear personal protective equipment. Special protective equipment for firefighters: Section6. ACCIDENTAL RELEASE MEASURES Use extra personal protective equipment (self-contained breathing apparatus). Keep Personal precautions, protective equipment and people away from and upwind of spill/leak. Ensure adequate ventilation. Entry to non- emergency procedures: involved personnel should be controlled around the leakage area by roping off, etc. 2-Methyl-2-butenenitrile Section6. ACCIDENTAL RELEASE MEASURES Environmental precautions: Prevent product from entering drains. Methods and materials for Absorb spilled material in dry sand or inert absorbent before recovering it into an containment and cleaning airtight container. In case of large amount of spillage, contain a spill by bunding. up: Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations. Prevention of secondary Remove all sources of ignition. Fire-extinguishing devices should be prepared in hazards:case of a fire. Use spark-proof tools and explosion-proof equipment. Section7. HANDLING AND STORAGE Precautions for safe handling Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment. Prevent generation of vapour or mist. Keep away from heat/sparks/open flame/hot surfaces. -No smoking. Take measures to prevent the build up of electrostatic charge. Use explosion-proof equipment. Wash hands and face thoroughly after handling. Use a closed system if possible. Use a ventilation, local exhaust if vapour or aerosol will be generated. Advice on safe handling: Avoid contact with skin, eyes and clothing. Conditions for safe storage, including any incompatibilities Keep container tightly closed. Store in a cool, dark and well-ventilated place. Storage conditions: Store under inert gas. Store locked up. Store away from incompatible materials such as oxidizing agents. Air-sensitive Packaging material:Comply with laws. Section8. EXPOSURE CONTROLS / PERSONAL PROTECTION Engineering controls:Install a closed system or local exhaust. Also install safety shower and eye bath. Personal protective equipment Respiratory protection: Half or full facepiece respirator, self-contained breathing apparatus(SCBA), supplied air respirator, etc. Use respirators approved under appropriate government standards and follow local and national regulations. Hand protection:Impervious gloves. Eye protection:Safety goggles. A face-shield, if the situation requires. Skin and body protection: Impervious protective clothing. Protective boots, if the situation requires. Section9.
