FIRST AID MEASURES Inhalation:Remove victim to fresh air and keep at rest in a position comfortable for breathing. Get medical advice/attention if you feel unwell. Skin contact:Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. 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. A rescuer should wear personal protective equipment, such as rubber gloves and air- Protection of first-aiders: 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 This substance may polimerize explosively when heated or involved in a fire. from the chemical:Container may explode when heated. Combat fire from a sheltered position. 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 Personal precautions,Use personal protective equipment. Keep people away from and upwind of spill/leak. 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 a containment and cleaning covered 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 Storage conditions:Keep container tightly closed. Store in a cool, dark and well-ventilated place. Store away from incompatible materials such as oxidizing agents. 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. sec-Butyl Ether (DL- and meso- mixture) (stabilized with HQ) Section8.
