FIRST AID MEASURES Remove victim to fresh air and keep at rest in a position comfortable for breathing. Inhalation: Get medical advice/attention if you feel unwell. Skin contact:Remove/Take off immediately all contaminated clothing. Gently wash with plenty of soap and water. If skin irritation or rash occurs: Get medical advice/attention. 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:Get medical advice/attention if you feel unwell. 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: 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. Special protectiveWhen extinguishing fire, be sure to wear personal protective equipment. equipment for firefighters: Section6. ACCIDENTAL RELEASE MEASURES Use personal protective equipment. Keep people away from and upwind of spill/leak. Personal precautions, protective equipment and Ensure adequate ventilation. Entry to non-involved personnel should be controlled emergency procedures: around the leakage area by roping off, etc. 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 an explosion-poof refregerator. Storage conditions: tert-Butyl Crotonate Section7. HANDLING AND STORAGE Store under inert gas.
