Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide can be used to control fire
Unsuitable Extinguishing Media: None known for this material
Hazardous Combustion Products: May release sodium oxides, carbon dioxide, and carbon monoxide if burned in fire
Special Protective Equipment: Wear full protective clothing and self-contained breathing apparatus when responding to large chemical fires
Fire & Explosion Hazards: Substance is not flammable or explosive but decomposition may release irritating gases in confined spaces
Personal Precautions: Wear appropriate chemical-resistant gloves, goggles, and lab coat or uniform
Environmental Precautions: Prevent entry to waterways, sewers, or drains; avoid spreading dust
Methods for Cleanup: Sweep up material without generating dust; collect in suitable, labeled container for reuse or disposal; clean spill area with water to remove residue
Safe Handling: Avoid inhaling dust by working with powders in well-ventilated area or under fume hood; keep containers tightly closed when not in use; use clean scoops or spatulas when removing material from container
Storage Requirements: Store in cool, dry, well-ventilated area; avoid humidity and direct sunlight; keep away from incompatible substances, especially strong acids or oxidizers
Incompatibilities: Mixing with strong acids may liberate carbon dioxide; mixing with oxidizing agents may cause reactions
Package Integrity: Use containers made of materials resistant to mild alkaline substances; properly label all containers before storage
Engineering Controls: Use local exhaust ventilation or lab fume hood when generating or handling dust
Personal Protective Equipment: Wear chemical-resistant gloves (like nitrile or PVC), safety glasses with side shields, and lab coat; use respiratory protection (dust mask or respirator) if dust generation expected above safe exposure levels
Exposure Limits: No established occupational exposure limits for sodium tartrate as set by OSHA, ACGIH, or NIOSH
Hygiene Measures: Avoid eating, drinking, or smoking in work area; wash thoroughly with soap and water after handling; remove contaminated clothing before leaving work area
Appearance: White crystalline powder or granules
Odor: Odorless
Melting Point: Decomposes above 170°C (338°F)
Boiling Point: Not applicable, substance decomposes before boiling
Solubility: Freely soluble in water; insoluble in most organic solvents such as ethanol or ether
Relative Density: About 1.79 g/cm³
pH (1% Solution): 7–9
Molecular Weight: 230.08 g/mol
Other Properties: Stable under recommended storage and handling conditions; effloresces in open air; hygroscopic if exposed to high humidity
Chemical Stability: Remains stable under ordinary conditions of use and storage
Reactivity: Reacts with strong acids to release carbon dioxide; may react with oxidizing agents and form new products
Hazardous Decomposition Products: May form sodium oxides, carbon monoxide, carbon dioxide under high temperature or fire
Polymerization: Will not undergo hazardous polymerization
Conditions to Avoid: Moisture, extreme heat, direct exposure to strong acids or oxidizers
Acute Toxicity: Oral LD50 in rats reported greater than 5,000 mg/kg indicating low acute toxicity
Skin and Eye Irritation: May cause mild irritation on contact; not considered a skin sensitizer
Chronic Effects: Not known to cause carcinogenic, mutagenic, or reproductive toxicity effects per available evidence
Additional Data: No evidence of organ damage or cumulative toxicity with normal workplace exposure; sodium tartrate is used in food processing in low concentrations; ingestion of large amounts can lead to gastrointestinal effects like diarrhea or discomfort
Ecotoxicity: No significant adverse effects noted in aquatic and terrestrial environments when present at typical environmental concentrations
Persistence and Degradability: Compound is biodegradable under natural conditions; does not bioaccumulate
Mobility: Soluble in water, can migrate through soil; unlikely to persist in environment under normal conditions
Other Adverse Effects: No data indicating chronic ecological risk; intended for use in applications with low environmental discharge potential
Disposal Methods: Collect waste material in sealed container; dispose of at approved chemical or hazardous waste facility; follow local, regional, national, and international waste regulations
Contaminated Packaging: Rinse and recycle if possible; otherwise, treat container as hazardous material
