Chemical Name: Potassium hydrogen tartrate
Chemical Identity: KC4H5O6
CAS Number: 868-14-4
Purity: Typically above 99% for laboratory or food-grade product
Impurities: May contain trace amounts of other tartrates or minerals from source material but at levels insignificant for safety concerns
Inhalation: Remove person to fresh air. Seek medical attention if irritation or difficulty breathing continues
Skin Contact: Wash the affected area with plenty of water and soap. Call a doctor if irritation develops or persists
Eye Contact: Flush immediately with plenty of water for at least 15 minutes. Remove contact lenses if present and continue rinsing. Consult a medical professional if redness or pain continues
Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical advice if large quantities are swallowed or symptoms persist
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide
Specific Hazards: Combustion may produce carbon oxides, potassium oxides, and irritating fumes
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective gear
Special Procedures: Keep substances and run-off out of drains and water supplies whenever possible
Personal Precautions: Avoid inhaling dust and contact with skin or eyes; wear appropriate protective clothing and equipment
Environmental Precautions: Prevent spill from entering drains, sewers, or waterways
Containment Methods: Sweep up or vacuum spilled material; avoid creating dust
Cleanup Methods: Dispose of collected material in accordance with local regulations; wash spill area thoroughly with water
Handling: Use with adequate ventilation to minimize dust; avoid prolonged or repeated contact with skin; avoid inhaling dust
Storage: Store in sealed containers in a cool, dry, well-ventilated location away from incompatible materials such as strong acids or bases
Incompatible Materials: Avoid strong oxidizers, strong acids, and strong alkalis
Exposure Limits: No occupational exposure limits established for potassium acid tartrate by OSHA, NIOSH, or ACGIH
Engineering Controls: Provide adequate ventilation; use local exhaust to maintain airborne concentrations below nuisance dust limits
Personal Protective Equipment: Wear gloves resistant to chemicals, safety goggles or glasses, and protective clothing if splashing or dust is possible. Use a respirator if dust levels exceed acceptable standards. Wash hands thoroughly after handling
