Inhalation: Move impacted person to fresh air, support breathing as required, seek medical evaluation for persistent symptoms
Skin Contact: Remove contaminated clothing, rinse area thoroughly with water and mild soap for at least 15 minutes, obtain medical support for irritation or persistent discomfort
Eye Contact: Flush eyes with water for at least 15 minutes, keep eyelids apart, seek medical attention for pain, redness, or vision changes
Ingestion: Do not induce vomiting, rinse mouth, seek immediate medical help, provide as much detail as possible about the material swallowed
Major Symptoms: Irritation, redness, upset stomach, burning sensation
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Specific Hazards: Combustion creates carbon oxides and irritating fumes; can contribute to fire intensity when mixed with oxidizers
Protective Equipment: Wear self-contained breathing apparatus, chemical-resistant turnout gear, use full face protection
Special Procedures: Remove containers from danger zone if possible, cool with spray to prevent rupture, avoid breathing dust and fumes
Personal Precautions: Use respirator, safety goggles, and gloves, avoid creating dust clouds
Environmental Precautions: Prevent runoff into sewers and waterways, contain spill using barriers or dikes
Methods for Clean-up: Scoop or vacuum spilled powder into labeled containers for disposal, flush remaining residue with water only if permitted by local regulations, ventilate area thoroughly after cleanup
Notification: Report significant spills to authorities based on local regulatory requirements
Handling: Wear personal protective equipment, prevent dust build-up, handle in well-ventilated areas or fume hoods
Storage: Store in tightly sealed containers, keep in cool, dry spaces away from incompatible materials such as strong oxidizers and bases, keep away from direct sunlight and moisture
Special Advice: Use original containers, label storage areas, separate toxic substances, check inventory dates regularly
Engineering Controls: Local exhaust ventilation, use of dust extraction units
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, full-length clothing, dust mask or NIOSH-certified respirator where dust exposure is high
Exposure Limits: No established OSHA PEL for tartaric acid, general nuisance dust (15 mg/m3 TWA ⎼ total dust, 5 mg/m3 respirable)
Hygiene Measures: Wash hands thoroughly after use, remove contaminated clothing, keep food and beverages away from work areas
Special Precautions: Avoid inhaling dust, prevent skin and eye contact, keep emergency eyewash stations accessible

Chemical Stability: Stable under normal temperatures and pressures, sensitive to moisture, decomposes with heat above 210°C
Reactivity: Reacts with strong oxidizers, bases
Hazardous Reactions: Releases carbon monoxide and carbon dioxide if burned, risk of violent reaction with some metal oxides
Conditions to Avoid: Prolonged heat, exposure to damp conditions, incompatible chemicals
Incompatible Materials: Alkalis, oxidizing agents, reducing agents, heavy metal compounds
Hazardous Decomposition Products: Carbon oxides, toxic fumes
Routes of Exposure: Skin, eye, inhalation, ingestion
Acute Toxicity: LD50 (Oral, rat) ≈ 4,350 mg/kg
Chronic Effects: Prolonged skin or eye contact can increase risk of dermatitis, higher dose ingestion can result in severe gastrointestinal distress
Symptoms: Redness, burning eyes, stomach cramps, vomiting, diarrhea
Carcinogenicity: Not classified as carcinogenic by NTP, IARC, OSHA
Other Relevant Data: No mutagenicity or reproductive risk identified in standard testing
Ecotoxicity: Harmful in concentrated forms to aquatic organisms, low persistence in environment due to biodegradability
Mobility: Readily soluble, potential to reach groundwater in significant spills
Persistence and Degradability: Biodegrades quickly under standard conditions
Bioaccumulative Potential: Unlikely to bioaccumulate due to high solubility and rapid metabolism
Other Adverse Effects: Large releases can cause temporary pH changes in bodies of water, altering aquatic habitats
Waste Disposal Methods: Dispose of substance in compliance with local, regional, national, and international regulations via licensed chemical waste contractor
Storage of Waste: Use sealed, labeled containers, segregate from incompatible waste streams
Contaminated Packaging: Rinse containers before recycling or disposing, use triple rinse method where required
Avoided Disposal Practices: Never discharge into surface waters, drains, or soils unless explicitly permitted by environmental authorities
Further Recommendations: Consider onsite neutralization or dilution for small laboratory volumes under supervision by environmental health personnel
