Chemical Name: D(+)-Tartaric Acid
CAS Number: 87-69-4
Concentration: 99% or higher purity (remainder usually water or trace impurities, varies by supplier).
Eye Contact: Immediately rinse eyes with clean, gently flowing water for at least 15 minutes, lifting upper and lower eyelids. Seek immediate medical attention if irritation persists.
Skin Contact: Remove any contaminated clothing. Wash skin with soap and plenty of water. If irritation continues, speak with a healthcare provider.
Inhalation: Move the person to fresh air. Provide artificial respiration if the person is not breathing. Consult a medical professional if symptoms develop or persist.
Ingestion: Rinse mouth with water; do not induce vomiting. Drink plenty of water. Do not give anything by mouth to an unconscious person. Contact a medical provider for further assessment.
Suitable Extinguishing Media: Use water spray, dry chemical, CO2, or alcohol-resistant foam.
Hazards from Combustion: Potentially releases carbon oxides (CO and CO2) when burnt.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and standard firefighting PPE.
Advice: Move containers from fire area if it can be done safely. Avoid inhaling combustion products.
Unusual Fire/Explosion Hazards: Dusts can form explosive mixtures with air, though not a major concern under typical storage.
Personal Precautions: Put on protective gloves, eye/face protection, and a dust mask or respirator. Ensure adequate air circulation.
Environmental Precautions: Prevent further leakage or spillage if safe. Keep product out of drains, surface waters, and soil.
Spill Cleanup: Sweep up or vacuum with non-sparking equipment. Avoid generating dust clouds. Place in suitable containers for disposal. Wash spill area with water. Ventilate affected area.
Handling: Handle only with adequate ventilation. Minimize dust formation by using careful application and transfer techniques. Use recommended personal protection.
Storage: Store in a tightly closed original container in a cool, dry, well-ventilated place away from incompatible materials such as strong oxidizers and bases. Keep container secure and avoid excess moisture uptake.
Hygiene: Wash hands thoroughly after handling. Do not eat, drink, or smoke in storage and work areas.
Engineering Controls: Use local exhaust or general room ventilation. Work in a chemical fume hood whenever possible.
Personal Protection: Wear safety goggles, chemical-resistant gloves (nitrile or rubber), and a laboratory coat. Use a dust mask (N95 or equivalent) or respirator in situations with excessive dust.
Occupational Exposure Limits: No specific limits established for D(+)-Tartaric Acid at national/international levels, but avoid inhalation of significant concentrations.
Additional Protection: Eye wash stations and safety showers should be nearby in work areas using tartaric acid.

Eye Effects: Causes irritation, redness, tearing, and pain.
Skin Effects: Prolonged or repeated exposure can cause dryness, slight irritation.
Inhalation Effects: Breathing dust may lead to nose and throat irritation, coughing.
Sensitization: No reports of sensitization observed.
Chronic Exposure: No known serious long-term effects at normal exposure levels.
Carcinogenicity, Teratogenicity, Mutagenicity: Not listed as carcinogenic by NTP, IARC, or OSHA. No data linking tartaric acid with birth defects or genetic changes in humans or animals.
Environmental Fate: Tartaric acid breaks down naturally in soil and water. Rapidly metabolized by microorganisms.
Aquatic Toxicity: Low toxicity to fish and aquatic life. High concentrations might lower water pH and disrupt sensitive aquatic species.
Mobility: Moves easily in water. Not known to bioaccumulate or persist.
Other Hazards: Spilled product can increase acidity in local soils or waterways if not promptly contained.
Waste Treatment Methods: Dispose of in accordance with local, regional, and national regulations. Small quantities can go with laboratory solid chemical waste. Large amounts should be managed through an approved chemical disposal company.
Environmental Precautions: Do not flush into surface water or sewer system. Dilute product before neutralization and disposal, if allowed.
Packaging Disposal: Clean and recycle containers if regulations permit, otherwise puncture and manage as hazardous waste.
UN Number: Not regulated for transport under current international guidelines.
