Ingredient Disclosure: No hazardous additives or intentionally included contaminants
Inhalation: Move individual to fresh air. Seek medical attention for persistent symptoms such as coughing or throat irritation.
Skin Contact: Wash affected area with soap and water; remove contaminated clothing. Seek medical help if irritation occurs.
Eye Contact: Flush eyes thoroughly with water for at least 15 minutes. Hold eyelids apart for effective rinsing. Contact medical staff if irritation persists.
Ingestion: Rinse mouth with water. Do not induce vomiting. Give water to dilute. Seek prompt medical attention if feeling unwell.
Notes to Physician: Symptomatic treatment – no specific antidote.
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide (CO₂)
Unsuitable Extinguishing Media: Direct water jets may spread burning material
Fire Hazards: May produce toxic fumes of carbon oxides on combustion
Special Protective Equipment for Firefighters: Full protective clothing and self-contained breathing apparatus
Additional Information: Approach fire from upwind position. Cool exposed containers with water spray.
Personal Precautions: Wear gloves, safety goggles, and protective clothing. Ventilate area. Avoid contact with spilled material.
Environmental Precautions: Prevent entry into sewers, watercourses, and confined spaces. Minimize environmental exposure with absorbent materials.
Methods for Clean-up: Stop leak if safe. Absorb with inert material such as sand. Collect in labeled, tightly closed containers for proper disposal.
Decontamination: Clean spill site thoroughly to remove traces. Dispose as chemical waste per regional safety requirements.
Safe Handling Practices: Handle in well-ventilated spaces. Avoid creating dust, aerosols, or vapor. Use appropriate PPE. Wash hands after handling.
Storage Conditions: Store in tightly sealed containers in cool, dry, well-ventilated areas. Protect from direct sunlight, moisture, and incompatible materials.
Incompatibilities: Strong oxidizing agents, acids, and bases can degrade product. Isolation from reactive chemicals keeps storage safe.
Storage Container Type: Use corrosion-resistant, sealed containers made of plastics or lined steel.
Occupational Exposure Limits: No established exposure limits for Acetyl Tributyl Citrate as set by ACGIH, OSHA, or NIOSH
Engineering Controls: Use local exhaust or general ventilation. Operations involving higher temperature or small particle generation may need enhanced containment.
