Inhalation: Move person to fresh air. Keep comfortable for breathing. If symptoms like coughing or shortness of breath persist, seek medical help.
Skin Contact: Remove contaminated clothing. Wash with plenty of soap and water. If irritation develops, get medical attention.
Eye Contact: Rinse gently with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. If irritation remains, consult a doctor.
Ingestion: Rinse mouth. Do not induce vomiting unless directed by medical personnel. Seek medical advice if feeling unwell.
Advice for Emergency Responders: Wear gloves and eye protection. Keep dust exposure as low as possible.
Suitable Extinguishing Media: Use dry chemical, water spray, foam, or carbon dioxide for small fires. Use water spray for larger fires.
Unsuitable Extinguishing Media: Do not use water jet directly, which may spread dust.
Special Hazards: Dust may form explosive mixtures in air. Burning can produce carbon oxides (CO, CO2).
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, protective clothing. Avoid inhaling combustion products.
Advice for Firefighters: Control runoff waters to prevent environmental contamination.
Personal Precautions: Ventilate area. Avoid dust formation. Use personal protective equipment such as gloves, safety glasses, and a dust mask.
Environmental Precautions: Do not allow product to enter watercourses or drains uncontrolled.
Methods for Cleanup: Sweep up and place in suitable containers for disposal. Dampen spilled material to reduce dust. Clean spill area with water to remove residues.
Other Information: Dispose of waste according to local regulations. Prevent further leakage or spillage where safe to do so.
Handling: Use only in well-ventilated areas. Wear recommended personal protective equipment. Prevent creation of airborne dust. Take care to avoid skin and eye contact. Do not eat, drink, or smoke when handling.
Storage: Store in tightly closed containers. Keep in dry, cool, well-ventilated places. Protect from moisture and water. Keep away from incompatible materials such as strong oxidizers and bases.
Other Precautions: Store away from food and beverages. Avoid stacking heavy containers.
Occupational Exposure Limits: No specific limits set for L(+)-Tartaric acid. Dust exposure should be kept as low as possible (<10 mg/m3 total dust as general nuisance dust guideline).
Engineering Controls: Local exhaust ventilation; process enclosures; use in areas with good general ventilation.
Eye Protection: Chemical safety goggles
Skin Protection: Wear protective gloves made from rubber or nitrile; use lab coats or aprons
Respiratory Protection: Use dust mask or respirator if workplace dust levels increase
Other Protection: Wash hands after handling. Remove contaminated clothing and launder before reuse.
