Other Components: No hazardous stabilizers or additives usually present
General Advice: Remove contaminated clothing, seek medical attention if symptoms persist
Eye Contact: Rinse cautiously with water for several minutes, lift eyelids to ensure thorough flushing, consult an eye specialist if irritation continues
Skin Contact: Wash with mild soap and plenty of water, consult a doctor if rash or discomfort arises
Inhalation: Move person to fresh air, keep at rest, contact healthcare provider if feeling unwell
Ingestion: Rinse mouth thoroughly with water, drink water if conscious, do not provoke vomiting, seek medical attention if symptoms appear
Main Symptoms: Redness, pain or irritation of affected area, coughing or mild respiratory discomfort from inhaling dust
Suitable Extinguishing Media: Dry chemical, CO2, foam, or water spray
Unsuitable Media: Avoid high-pressure water streams that might spread dust
Special Hazards: At high temperatures, decomposition may produce carbon oxides, avoid inhaling smoke
Firefighting Instructions: Evacuate area, use self-contained breathing apparatus if exposed to decomposition products, maintain a safe distance
Protective Equipment: Full protective clothing and respiratory equipment for firefighters
Personal Protection: Avoid breathing powder, don protective gloves and eye protection, minimize skin contact
Environmental Precautions: Avoid runoff into drains or waterways, contain spill to prevent soil contamination
Spill Cleanup: Scoop or sweep up without generating excessive dust, place in labeled containers for disposal, ventilate area
Decontamination: Wash exposed area with water, launder or dispose of contaminated clothing based on company guidelines
Safe Handling: Use with adequate ventilation, avoid dust generation, wash hands before eating or drinking after use, use non-sparking tools if necessary
Storage Conditions: Store in a cool, dry, well-ventilated location, keep container tightly closed, protect from moisture, segregate from bases and oxidizers
Incompatible Materials: Strong oxidizing agents and strong bases, substances that react with organic acids
Hygiene Practice: Clean work area after handling, prevent contamination of food and beverages, keep containers clearly labeled
Occupational Exposure Limits: No established limit for tartaric acid, avoid excessive exposure through general dust limits (often 10 mg/m3 for inhalable dust)
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure guidelines
Personal Protective Equipment: Chemical-resistant gloves, safety goggles or face shield, lab coat or apron, dust mask in case of limited ventilation
General Controls: Remove contaminated clothing, wash thoroughly after handling, avoid eating or drinking in the work area
