Purity: Typically > 85%
Impurities: Sodium chloride, sodium sulfate, minor organic impurities below 2% total
Nature: Synthetic monoazo dye
Inhalation: Move person to fresh air, offer oxygen if there is difficulty breathing. Seek medical attention for prolonged symptoms.
Skin Contact: Remove contaminated clothing. Wash affected area with plenty of water and mild soap.
Eye Contact: Rinse immediately with running water for at least 15 minutes. Lift eyelids to ensure thorough flushing.
Ingestion: Rinse mouth. Do not induce vomiting. Give small quantity of water to drink. Get medical attention if symptoms develop. Monitor for signs of allergic reaction.
Suitable Extinguishing Media: Water spray, foam, dry chemical powder, carbon dioxide
Unsuitable Media: None known
Specific Hazards: Emits toxic fumes (nitrogen oxides, sulfur oxides, carbon monoxide) during combustion
Firefighter Protection: Use full protective gear and self-contained breathing apparatus.
Additional Advice: Prevent runoff from entering drains or watercourses. Remain upwind and avoid smoke exposure.
Personal Precautions: Evacuate area for large spills. Use gloves, protective eyewear, dust mask. Avoid contact with eyes and skin.
Environmental Precautions: Prevent powder or solution from entering waterways, sewers, or soil. Inform relevant authorities if significant release occurs.
Methods for Cleaning Up: Contain and sweep up with minimal dust formation. Collect in suitable containers for disposal. Wash area with water, absorbing run-off with inert material. Dispose as hazardous waste according to local regulations.
Safe Handling: Handle in well-ventilated location. Avoid ingestion and inhalation. Wear protective equipment. Prevent formation of dust clouds.
Storage: Keep container tightly sealed. Store in cool, dry, well-ventilated space, away from incompatible materials (strong oxidizers, reducing agents). Avoid sunlight, heat sources, moisture.
Other Advice: Store away from food, beverages, and animal feed. Keep containers labeled and off the floor.
Occupational Exposure Limits: No established OSHA/NIOSH limits for tartrazine; minimize dust exposure.
Engineering Controls: Exhaust ventilation, local fume extraction recommended in processing areas.
Personal Protection: Protective gloves (nitrile or latex), chemical safety goggles, lab coat or apron, NIOSH-approved respirator in dusty environments.
Hygiene: Wash hands thoroughly after handling. Remove contaminated clothing and wash before reuse.
