Chemical Identity: Diisopropyl-L-tartrate
Concentration: >98%
Impurities: Not expected at levels sufficient to influence classification or contribute to hazards
Additional Components: Substance not formulated with significant additives or other chemicals
Inhalation: Move exposed person to fresh air. Keep at rest in comfortable position. Seek medical advice if symptoms persist.
Skin Contact: Remove contaminated clothing. Rinse skin immediately with plenty of water for at least 15 minutes. Seek medical attention if irritation develops.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Get medical attention if eye irritation persists.
Ingestion: Rinse mouth thoroughly with water. Do not induce vomiting. Give small amounts of water to drink if the person is conscious. Call a physician or poison center.
Extinguishing Media: Suitable media include water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Do not use a direct water jet.
Specific Hazards: Vapors may form explosive mixtures with air. Containers can explode under heat or fire conditions. Thermal decomposition can produce irritating and toxic gases such as carbon monoxide and carbon dioxide.
Protective Equipment: Firefighters wear self-contained breathing apparatus with full protective clothing. Eliminate all ignition sources and ventilate area if safe to do so.
Advice for Firefighters: Approach from upwind to avoid directed heat and smoke. Cool closed containers with water mist.
Personal Precautions: Wear appropriate personal protective equipment including gloves, goggles, and lab coat. Remove all sources of ignition. Ensure adequate ventilation.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains, watercourses, or soil.
Methods for Clean Up: Absorb spill with inert material (such as dry sand or earth). Collect into containers for disposal according to local regulations. Clean surface thoroughly to remove residue.
Notification Procedures: Report spills as required by local, regional, or national authorities.
Handling: Wear suitable protective equipment when handling. Avoid direct contact with eyes, skin, and clothing. Do not breathe vapors or mist. Use only with adequate ventilation. Avoid sources of ignition such as open flame or static discharge.
Storage: Store in a tightly closed container in a cool, dry, and well-ventilated place away from sources of ignition and incompatible substances like strong oxidizers and acids. Keep away from food and drinks. Protect from moisture and sunlight.
Occupational Exposure Limits: Not established for Diisopropyl-L-tartrate
Engineering Controls: Use with adequate general and local exhaust ventilation to maintain exposures below occupational limits where possible.
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile recommended), safety glasses with side-shields or goggles, and lab coat. Use respiratory protection in poorly ventilated spaces or if exposure limits are exceeded. Use face protection for large volume handling.
Hygiene Measures: Wash hands after use, before eating, drinking, or contact with skin and eyes. Do not eat, drink, or smoke during use.
