Inhalation: Move person to fresh air. Seek medical attention if symptoms persist. Provide oxygen if breathing is difficult.
Skin Contact: Wash affected area thoroughly with soap and plenty of water. Remove contaminated clothing. If irritation develops, get medical aid.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and get medical attention.
Ingestion: Do not induce vomiting. Rinse mouth with water. Seek medical attention immediately.
Suitable Extinguishing Media: Use dry chemical, alcohol-resistant foam, carbon dioxide, or water spray.
Unsuitable Extinguishing Media: Do not use direct water jet; may spread fire.
Specific Hazards: Vapors may form explosive mixtures with air. Combustion yields carbon oxides and irritating fumes.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear.
Special Procedures: Cool containers with water spray to prevent pressure buildup and potential explosion.
Personal Precautions: Evacuate area if vapor present. Ensure adequate ventilation. Use personal protective equipment.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid release to waterways, sewers, and soil.
Methods for Containment and Cleaning Up: Absorb liquid with inert material (sand, earth, vermiculite). Shovel into suitable container for disposal. Wash spill area with water, avoid runoff.
Safe Handling Recommendations: Use only in well-ventilated places. Keep away from open flames, hot surfaces, and sources of ignition. Avoid breathing vapors and contact with skin and eyes. Wash hands after handling.
Storage Conditions: Store in tightly closed containers in a cool, dry, and well-ventilated location. Keep away from incompatible substances such as strong oxidizers and acids. Protect from sunlight and static discharge.
Incompatible Materials: Strong acids, bases, oxidizing agents.
Exposure Limits: No established regulatory exposure limits for Ethyl 2-methylbutanoate.
Engineering Controls: Use exhaust ventilation to limit exposure to vapor.
Personal Protective Equipment: Use chemical-resistant gloves, safety goggles, and protective clothing.
Respiratory Protection: Use NIOSH-approved respirator if exposure may exceed recommended limits or ventilation is inadequate.
General Hygiene: Wash thoroughly after handling. Do not eat, drink, or smoke while working with this product.
