Impurities: Trace amounts of water and possible minor contaminants depending on source
General Advice: Seek medical attention if exposure causes symptoms or irritation persists
Inhalation: Move to fresh air, get medical assistance if breathing becomes difficult
Skin Contact: Wash with plenty of water and soap, remove contaminated clothing, seek help if irritation develops
Eye Contact: Rinse immediately with water for 15 minutes, seek prompt medical advice, avoid rubbing eyes
Ingestion: Rinse mouth, do not induce vomiting, get medical attention in case of large ingestion or discomfort
Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Special Hazards: May release irritating fumes like carbon oxides under fire conditions
Protective Equipment: Firefighters use full protective gear and self-contained breathing apparatus
Combustion Products: Carbon monoxide, carbon dioxide from thermal decomposition
Fire Hazards: Avoid inhaling combustion gases, prevent runoff from contaminating water supply
Personal Precautions: Use dust mask, wear protective clothing, avoid contact with skin and eyes
Environmental Precautions: Prevent spillage from entering drains, soil, or water sources, gather any spilled material for proper disposal
Methods for Clean-up: Sweep or vacuum spilled material, avoid dry sweeping if dust generation occurs, place in suitable containers for disposal, ventilate the area well, clean surfaces with water after removal
Handling: Avoid contact with eyes, skin, and clothing, use in well-ventilated areas, minimize dust generation
Advice on Safe Handling: Do not inhale dust, avoid eating, drinking, or smoking while handling
Storage Conditions: Store in tightly closed container, keep in a dry and well-ventilated place, protect from moisture and incompatible substances (strong oxidizers, bases)
Incompatible Materials: Strong bases, strong oxidizing agents
Special Rules: Prevent storage near food, feed, or potable water
Exposure Limits: No established OSHA, ACGIH, or NIOSH limits for tartaric acid
Engineering Controls: Local exhaust when excessive dust forms, normal room ventilation typically sufficient
Personal Protection: Eye/face protection (safety goggles), skin protection (chemical-resistant gloves), respiratory protection (dust mask or respirator for high concentrations)
