Eye Contact: Rinse with plenty of water, keep eyelids open, seek medical advice if irritation continues
Skin Contact: Wash with soap and water, remove contaminated clothing, seek medical attention if symptoms persist
Inhalation: Move person to fresh air, keep airway open, provide medical attention in case of irritation or persistent discomfort
Ingestion: Rinse mouth, do not induce vomiting unless instructed by healthcare provider, seek medical advice if large quantity is swallowed
General Advice: Always consult a physician if feeling unwell after exposure, provide SDS to the physician for specific guidance
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: Avoid high-pressure water jets
Specific Hazards During Fire: Releases carbon oxides (CO, CO2) when burned, may produce acrid smoke or fumes
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Specific Methods: Use water spray to cool containers near fire, prevent fire water from entering drains or water courses
Personal Precautions: Wear suitable protective equipment including gloves and eye protection, ventilate area
Spill Response: Absorb liquid with inert material (sand or earth), collect residue in a suitable container, wash spill site thoroughly after material pickup
Environmental Precautions: Avoid release into drains, surface water, or soil, inform authorities if significant spill threatens environment
Cleanup Methods: Use non-sparking tools, collect and dispose of contaminated material as waste according to local regulation
Safe Handling: Use only with adequate ventilation, minimize creation of mist, avoid skin and eye contact, do not eat or drink while handling product
Safe Storage: Store in cool, well-ventilated dry area away from incompatible materials like strong oxidizers, acids or bases, keep containers tightly closed when not in use
Other Precautions: Avoid extreme temperatures, protect from sunlight and moisture, label containers clearly
Incompatible Materials: Strong acids, strong bases, strong oxidizing agents
Occupational Exposure Limits: No established limits for Triethyl Citrate
Engineering Controls: Local exhaust ventilation recommended for bulk handling operations
Personal Protective Equipment: Protective gloves (nitrile or PVC), chemical goggles, lab coat or apron, if risk of splash
Respiratory Protection: Not usually needed in open, ventilated areas; where mist is present, use appropriate organic vapor respirator
Hygiene Measures: Wash hands thoroughly after handling, keep food and drink away from work area, remove contaminated clothing after use

Likely Routes of Exposure: Inhalation of mist, skin contact, eye contact, ingestion
Acute Toxicity: Oral LD50 (rat): >5,000 mg/kg (low toxicity), similar low dermal toxicity
Chronic Effects: No evidence of carcinogenicity, mutagenicity, or reproductive toxicity in animal studies
Skin Irritation: Mild, reversible irritation with prolonged or repeated contact
Eye Irritation: Mild, reversible irritation if splashed into eye
Sensitization: Not expected to cause allergic skin or respiratory reaction
Other Effects: No evidence of serious systemic health effects at low exposure levels
Medical Condition Aggravated by Exposure: Existing dermatitis, asthma, or respiratory issues may worsen with exposure to aerosol or mist
Aquatic Toxicity: Low acute toxicity toward fish and aquatic invertebrates
Persistence and Degradability: Biodegrades relatively quickly in environment
Bioaccumulative Potential: Low, due to water solubility and moderate molecular weight
Mobility in Soil: High mobility possible, but rapid biodegradation limits persistence
Other Adverse Effects: Large spills could pose local risk to aquatic life, should not be released uncontrolled
