Thermal Decomposition Products: Chlorine compounds, nitrogen oxides, carbon oxides
Personal Precautions: Wear appropriate respiratory protection, gloves, and goggles
Environmental Precautions: Prevent release to surface water, sewer, or soil
Cleanup Methods: Sweep up and place in suitable, labeled containers; avoid raising dust; ventilate area
Disposal: Collect for disposal per local regulations
Spill Response: Wash affected area with soap and water after cleaning
Handling: Minimize dust formation; avoid contact with skin, eyes, and clothing; use only in well-ventilated areas
Storage Conditions: Store in dry, well-ventilated location; keep containers tightly closed; protect from moisture, direct sunlight, and incompatible chemicals
Incompatibilities: Strong oxidizers, strong bases
Special Precautions: Use antistatic measures; always transfer using grounded equipment if large quantities handled
Storage Temperature: Ambient temperatures, away from sources of heat and ignition
Exposure Limits: No occupational exposure limits established for choline chloride
Engineering Controls: Local exhaust ventilation in areas where dust may be generated
Personal Protective Equipment: Safety glasses or goggles; chemical-resistant gloves; dust mask or respirator in dusty environments; laboratory coats or work clothing
Hygiene Measures: Wash hands after handling; do not eat, drink, or smoke near product

Acute Toxicity (Oral LD50): Rat: >3,000 mg/kg
Routes of Exposure: Inhalation, skin, eye, ingestion
Potential Health Effects: Mildly irritating to eyes, skin, and respiratory tract; large oral doses may cause gastrointestinal distress
Skin Irritation: Low
Eye Irritation: Moderate but reversible
Chronic Effects: No evidence for long-term toxicity, carcinogenicity, mutagenicity, or reproductive toxicity in humans or animals at occupational exposure levels
Sensitization: Not reported
Aquatic Toxicity: Not expected to be hazardous, but high concentrations can cause localized disruptions in aquatic systems
Persistence and Degradability: Rapidly biodegradable in water and soil
Bioaccumulation: Low potential due to high solubility and rapid metabolism
Soil Mobility: High water solubility can allow migration in moist soils, but ready biodegradability mitigates risk
Other Effects: Large quantities may contribute to nutrient enrichment if released untreated
