INHALATION: Move affected person to fresh air, seek medical attention if symptoms persist, provide oxygen if serious difficulty arises
SKIN CONTACT: Wash thoroughly with soap and water, remove contaminated clothing, consult a physician for persistent irritation
EYE CONTACT: Flush eyes with plenty of water for at least 15 minutes, lift eyelids occasionally, obtain medical assistance if discomfort continues
INGESTION: Rinse mouth, do not induce vomiting, drink water if conscious, obtain medical attention, specify exposure to D-Dimethyl tartrate
SUITABLE EXTINGUISHING MEDIA: Use foam, dry powder, carbon dioxide, or water spray; avoid direct stream if possible
SPECIAL HAZARDS ARISING: Thermal decomposition can give off carbon dioxide and carbon monoxide, potential for acrid smoke
PROTECTIVE EQUIPMENT FOR FIREFIGHTERS: Wear self-contained breathing apparatus, use full protective gear, evacuate area as needed
ADDITIONAL INFORMATION: Containers exposed to heat may rupture, avoid inhaling fumes from fire, contain run-off water to prevent spread
PERSONAL PRECAUTIONS: Use chemical-resistant gloves, safety goggles, dust mask if high concentration present
ENVIRONMENTAL PRECAUTIONS: Prevent entry into drains or watercourses, gather spilled material for disposal, ventilate area
CLEAN-UP METHODS: Sweep up gently using non-sparking tools, collect in suitable container for waste disposal, wash area with plenty of water
ADDITIONAL ADVICE: Avoid dust generation, ensure proper ventilation during clean-up, dispose in accordance with local regulations
HANDLING: Minimize dust production, wear protective gloves and eye protection, avoid eating or drinking in handling area, practice good industrial hygiene
STORAGE: Store in tightly closed container in a cool, dry, well-ventilated location away from incompatible substances, protect from moisture
INCOMPATIBLE MATERIALS: Strong oxidizing agents, acids, bases, avoid storage near open flame or heat sources
SPECIAL SENSITIVITY: Reacts slowly with strong oxidizers or bases, avoid prolonged exposure to air or moisture which may degrade compound
EXPOSURE LIMITS: No established occupational exposure limits; treat as nuisance dust (typically <10 mg/m3 for inhalable dust)
ENGINEERING CONTROLS: Use local exhaust ventilation or work in chemical fume hood, maintain good airflow, employ dust collectors if large volumes handled
PERSONAL PROTECTIVE EQUIPMENT: Wear disposable gloves (nitrile or PVC recommended), chemical safety glasses or goggles, dust mask or respirator if handling powder, laboratory coat
HYGIENE MEASURES: Wash hands after handling, change contaminated clothes, avoid rubbing eyes or face during use

VAPOR PRESSURE: Negligible at room temperature
FLASH POINT: Not determined, likely high, use caution around ignition sources
PARTICLE SIZE: Varies by supplier and batch, not respirable unless milled
STABILITY: Stable under recommended handling and storage conditions
REACTIVITY: Not reactive with most common laboratory chemicals
HAZARDOUS POLYMERIZATION: Does not occur
CONDITIONS TO AVOID: Excessive moisture, heat, incompatible chemicals
HAZARDOUS DECOMPOSITION PRODUCTS: Produces carbon dioxide, carbon monoxide, possible minor acids when heated or combusted
INCOMPATIBLE SUBSTANCES: Avoid oxidizers, strong alkalis, avoid direct exposure to acids
ROUTES OF EXPOSURE: Inhalation, ingestion, skin and eye contact
ACUTE EFFECTS: Slight skin and eye irritation, coughing or respiratory irritation if inhaled, minor stomach upset possible on ingestion
CHRONIC EFFECTS: Insufficient data in published literature to identify long-term effects; no carcinogenicity documented
LD50 VALUES: Not determined for D-dimethyl tartrate specifically, references to related tartrates indicate low acute toxicity >2000 mg/kg (oral, rat)
OTHER INFORMATION: Not listed as reproductive toxin, mutagen, or carcinogen by IARC, NTP, or OSHA
AQUATIC TOXICITY: Limited data available; structurally similar tartrates show low toxicity to aquatic organisms
PERSISTENCE AND DEGRADABILITY: Biodegradable, expected to break down naturally in environment
BIOACCUMULATIVE POTENTIAL: Not expected to bioaccumulate or persist in biological systems
MOBILITY IN SOIL: Soluble in water, capable of moving through soil with water
OTHER ENVIRONMENTAL EFFECTS: Avoid uncontrolled release to surface watercourses; excess material can affect pH or oxygen levels
DISPOSAL METHODS: Collect waste in suitable sealed container, label material clearly, send for disposal at licensed chemical waste facility
CONTAMINATED PACKAGING: Rinse containers well, dispose through chemical waste stream, comply with local environmental regulations
