Main Symptoms: May include itching, redness, coughing, burning feeling in eyes or skin
Note to Physician: Treat symptomatically, no specific antidote known
Safety Precautions: Emergency responders should use protective equipment to avoid exposure
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Unsuitable Media: None identified for this salt, but avoid direct stream of water to avoid product dispersal
Hazardous Combustion Products: Emits carbon oxides, sodium and potassium oxides under intense heat
Specific Hazards: No explosive or highly flammable properties, but product can aid fire situations if present with incompatible materials
Protective Equipment: Firefighters use full protective clothing and self-contained breathing apparatus
Special Procedures: Move containers from fire area if it can be done safely, cool unopened containers with water spray
Personal Precautions: Avoid creating dust, ventilate area, wear appropriate personal protective equipment such as gloves, goggles, and dust mask
Environmental Precautions: Prevent spillage from reaching drains, soil, or surface water bodies
Methods for Clean-up: Scoop up spill and place in a suitable, labeled container for proper disposal, wash spill area with water after material pickup
Decontamination: Use soap and water on affected surfaces
Emergency Procedures: Restrict access to area until clean-up is complete, provide notification to safety personnel for significant spills
Handling: Use in well-ventilated areas, avoid breathing dust, minimize contact with eyes and skin, follow workplace hygiene standards, do not eat, drink, or smoke during use
Storage Conditions: Store tightly closed in a cool, dry, well-ventilated location away from strong acids or oxidizers
Packaging Materials: Compatible with high-density polyethylene, glass, or lined drums
Incompatibilities: Strong acids, strong oxidizers
Engineering Practices: Label storage containers clearly, segregate from incompatible chemicals
Special Precautions: Keep container tightly sealed to minimize moisture absorption and clumping of the salt
Occupational Exposure Limit: Not established for sodium potassium tartrate; general nuisance dust standards apply (Total dust 10 mg/m³, Respirable dust 5 mg/m³, as per OSHA)
Engineering Controls: Local exhaust ventilation or general dilution ventilation to control airborne concentrations
Personal Protective Equipment: Safety goggles, gloves (nitrile or PVC), standard laboratory coats; half-face respirator if dust levels exceed limits
Hygiene Measures: Wash hands after use, do not touch face during use, remove contaminated clothing before eating
Appearance: White crystalline powder or colorless crystals

Melting Point: Decomposes at 70°C
Boiling Point: Not available
Density: 1.79 g/cm³
Solubility: Easily soluble in water, insoluble in alcohol
pH (aqueous solution): Approximately 7-8 (for 1% solution)
Vapor Pressure: Not applicable

Oxidizing Properties: Not oxidizing
Partition Coefficient: Not determined
Auto-Ignition Temperature: Not applicable
Decomposition Temperature: Over 70°C, with water loss
Chemical Stability: Stable at standard temperatures and storage conditions
Reactivity: Non-reactive under normal handling and use
Incompatibility: Strong acids release tartaric acid, strong oxidizers may initiate exothermic reactions
Hazardous Decomposition: Formation of carbon monoxide, carbon dioxide, sodium and potassium oxides under high heat or fire
Polymerization: Will not occur
Special Conditions to Avoid: Avoid excessive heat or moisture, prolonged exposure to air can cause caking
Acute Toxicity: Oral LD50 (rat) >5020 mg/kg, substance considered of low acute toxicity
Skin Corrosion/Irritation: May cause mild transient skin irritation
Serious Eye Damage / Eye Irritation: Causes serious eye irritation due to crystal formation
Respiratory Effects: Dust can cause irritation of respiratory passages; chronic exposure not well studied but is not expected to cause serious effects
Sensitization: No evidence for skin or respiratory sensitizer characteristics
Chronic Toxicity: Based on studies, not expected to be carcinogenic or mutagenic, not known to cause reproductive toxicity
Other Effects: Ingestion of very large amounts may lead to gastrointestinal upset; rare reports of tartaric acid salts causing metabolic disturbances if ingestion is excessive; safe in typical quantities encountered
Ecotoxicity: Low potential for aquatic toxicity, LD50 (fish, 96h): >1000 mg/L
Persistence & Degradability: Readily biodegradable in water and soil
Bioaccumulation: Not bioaccumulative in aquatic organisms
Soil Mobility: High solubility allows for migration in soil, but natural decomposition into harmless products
Environmental Fate: Breaks down to carbon dioxide and inorganic ions in environment; tartaric and potassium ions are widely distributed in nature
Adverse Effects: Accidental large releases may contribute to increased biochemical oxygen demand in water bodies; unlikely to present long-term risks
