Inhalation: Move person to fresh air, provide oxygen if breathing is difficult, consult medical personnel if symptoms do not resolve.
Ingestion: Rinse mouth, drink water to dilute, never induce vomiting unless directed by medical personnel, seek prompt medical advice.
Notes to Physician: Treat symptomatically and monitor for irritation or allergic reactions in sensitive individuals.
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam based on fire conditions.
Unsuitable Extinguishing Media: Do not use a direct water stream to avoid material spreading.
Specific Hazards: Material may burn under intense fire conditions, producing irritating carbon oxides including carbon monoxide and carbon dioxide.
Protective Equipment: Firefighters should wear full protective gear and a self-contained breathing apparatus.
Fire-Fighting Instructions: Apply suitable extinguishing agent, remove product containers if safe, avoid inhaling combustion gases.
Personal Precautions: Use personal protective equipment, avoid dust generation and inhalation, ventilate area.
Environmental Precautions: Prevent runoff into drains, sewers, or surface waters, isolate spill from environmental discharge points.
Spill Clean-up Methods: Sweep or shovel spilled material, collect in properly labeled containers for disposal, wash area with water to remove any residue, avoid creating airborne dust.
Disposal: See disposal considerations section for approved waste management approaches.
Handling: Keep containers tightly closed, use with adequate ventilation to minimize dust exposure, wear protective gloves and eye protection.
Storage: Store in a cool, dry, well-ventilated place, away from incompatible materials such as strong bases and oxidizing agents, protect from moisture and humidity.
Incompatibilities: Avoid contact with alkalis, reducing agents, and strong oxidizers; store away from reactive chemicals.
Specific End Use(s): Handle according to manufacturer recommendations for food and laboratory use.
Exposure Limits: Not established for tartaric acid in most jurisdictions, minimize dust inhalation through engineering controls.
Engineering Controls: Local exhaust, general mechanical ventilation, dust collection systems in areas with high airborne concentration.
Personal Protection: Wear chemical safety goggles, dust-proof gloves, protective clothing and, when necessary, NIOSH-approved dust respirators.
Hygiene Measures: Avoid eating or drinking while handling material, practice thorough handwashing after use, launder contaminated clothing before reuse.
