Inhalation: Move affected person to fresh air immediately. Seek medical attention if symptoms persist such as coughing, shortness of breath, or throat irritation.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. Get medical attention for ongoing irritation, redness, or allergic reaction.
Eye Contact: Rinse eyes with water for at least fifteen minutes, holding eyelids open. Remove contact lenses, if present. Seek medical attention if any discomfort persists.
Ingestion: Do not induce vomiting unless directed by medical personnel. Rinse mouth and drink water if conscious. Contact a poison control center or physician for guidance.
Most Important Symptoms: Redness, mild irritation, or discomfort; in rare cases, allergic symptoms in sensitive individuals
Suitable Extinguishing Media: Use dry chemical powder, foam, carbon dioxide, or water spray for small fires. Do not use high pressure water jets directly.
Unsuitable Extinguishing Media: Direct water may spread liquid fire over large areas.
Fire Hazards: Material may emit toxic vapors such as carbon oxides (CO, CO₂) under fire conditions. Generates dense white smoke if heated excessively.
Protective Equipment: Firefighters risk smoke inhalation and need full-face, self-contained breathing apparatus, and chemical-resistant protective clothing.
Special Procedures: Avoid runoff entering drains or waterways; collect contaminated water for disposal.
Personal Protection: Use gloves, goggles, and suitable protective clothing. Ensure adequate ventilation in affected area.
Environmental Precautions: Prevent entry into sewers, surface water, or soil. Dike spill and use inert absorbent material (sand or earth).
Containment: Stop leak at source; absorb liquid on inert material; transfer waste to container for proper disposal.
Cleanup Methods: Wash contaminated surfaces with soap and water. Dispose of residues in accordance with local environmental regulations.
Handling Precautions: Avoid breathing vapor or mist. Minimize skin and eye contact using gloves and goggles. Maintain good industrial hygiene by washing hands thoroughly after handling.
Safe Storage: Keep container tightly closed and store in a cool, well-ventilated area, away from strong oxidizers and sources of heat or ignition.
Special Requirements: Use only containers made of compatible materials such as polyethylene, glass, or steel with corrosion-resistant coatings. Inspect containers for leaks before use.
Other Considerations: Store away from food, drink, and animal feedstuffs. Label containers properly.
Occupational Exposure Limits: No established ACGIH, OSHA, or EU exposure limits for tributyl acetyl citrate.
Engineering Controls: Use local exhaust ventilation or work in a fume hood if there is potential for airborne exposure.
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile, neoprene), safety goggles or face shield, and a lab coat or apron. Respiratory protection (N95 or greater) is recommended if airborne concentrations become significant.
Hygiene Practices: Wash hands and face thoroughly after handling. Remove contaminated clothing and wash before reuse.

Acute Toxicity: Studies show low oral toxicity; LD50 oral (rat): > 6400 mg/kg
Skin Contact: May cause mild irritation in sensitive people. Does not sensitize skin under standard exposure.
Eye Contact: Direct splashes induce mild and reversible irritation.
