First Aid Measures

Inhalation: Move impacted individual to fresh air without delay; Seek medical attention if difficulty breathing or persistent coughing occurs
Skin Contact: Remove any contaminated clothing; Wash skin thoroughly using water and non-abrasive soap; Seek assistance if redness or irritation persists
Eye Contact: Rinse carefully with clean, tepid water for 15 minutes, holding eyelids apart; Remove contact lenses if present and comfortable; Consult medical professional for ongoing discomfort
Ingestion: Rinse mouth gently with water; Do not force vomiting; Obtain medical advice immediately, presenting product label if accessible
Most Important Symptoms: Red or itchy skin, eye stinging or watering, possible mild respiratory upset, nausea
Recommendations for Physicians: Provide symptomatic and supportive care based on exposure severity

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, or foam extinguishers for small fires; Water spray or fog for larger scale
Hazards during Fire: May emit toxic fumes (carbon oxides, benzoic vapors) if combusted at high temperatures; Dense smoke formation possible in enclosed spaces
Protective Equipment: Firefighters should use self-contained breathing apparatus and protective clothing
Advice: Cool exposed sealed containers using water mist and remove from fire zone if safe

Accidental Release Measures

Personal Precautions: Don appropriate gloves and eye protection before touching or collecting spillage; Avoid contact with skin and eyes
Environmental Precautions: Keep material out of drains, waterways, or soil; Collect spillage using dedicated absorbent material and prevent wider environmental exposure
Cleanup Methods: Scoop or gently brush up material; Transfer to labeled waste container; Clean area with copious water, ventilate zone well to disperse dust
Notification Procedures: Inform responsible authorities if material reaches public sewage or environment in significant quantities

Handling and Storage

Handling Precautions: Work in well-ventilated areas and make use of fume hoods for powder transfer; Avoid creating dust clouds or inhaling dust; Wear proper PPE such as nitrile gloves, lab coat, and safety glasses
Hygiene Protocols: Wash hands and face after use, especially before eating or drinking; Maintain clean workspace, clean spills rapidly
Storage Conditions: Store tightly closed container in a cool, dry, well-ventilated area away from strong acids or bases; Product stability supported by refrigeration but not freezing; Shield from direct sunlight and moisture
Incompatible Materials: Strong oxidizing agents or strong bases may react and compromise safety or purity

Exposure Controls and Personal Protection

Exposure Limits: Occupational exposure limits not established for this compound; General dust limits recommend keeping inhalable dust below 10 mg/m³
Engineering Controls: Use local exhaust ventilation or work inside chemical fume hoods for significant transfers; Keep containers closed between uses
Personal Protective Equipment: Chemical splash-resistant safety goggles, disposable nitrile gloves, laboratory coat or apron; In poorly ventilated settings, use NIOSH/MSHA-approved dust respirator
Environmental Protection: Implement spill containment, enforce careful waste management, avoid uncontrolled discharges

Ecological Information

Ecotoxicity: No direct aquatic toxicity data, but tartaric acid derivatives have low bioaccumulation and moderate aquatic toxicity
Bioaccumulation Potential: Product considered readily biodegradable, low bioaccumulation forecast
Mobility in Soil: Typically low mobility because of low water solubility and strong adsorption to sediments
Environmental Fate: Degrades slowly in environment through microbial action and photolysis; Avoid uncontrolled release
