Chemical Name: Triethyl Orthopropionate
CAS Number: 122-34-9
Concentration: ≥98% by weight
Impurities: May contain trace amounts of related esters or ethanol
Molecular Formula: C9H20O3
Inhalation: Move person to fresh air. If breathing is difficult, provide oxygen. Contact medical assistance if symptoms persist.
Skin Contact: Wash affected area with plenty of water and mild soap. Remove contaminated clothing and seek medical attention if irritation develops.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Seek medical advice if discomfort continues.
Ingestion: Do not induce vomiting. Rinse mouth with water. Get immediate medical attention. Never give anything by mouth to an unconscious person.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, alcohol-resistant foam
Unsuitable Extinguishing Media: Water jet
Specific Hazards: Vapors may form explosive mixtures with air. Thermal decomposition can produce carbon monoxide, carbon dioxide, irritating fumes.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear.
Firefighting Instructions: Cool exposed containers with water spray. Evacuate area and fight fire from a safe distance.
Personal Precautions: Evacuate area, eliminate ignition sources, ventilate space. Avoid inhalation or contact with skin or eyes.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not release into drains or water sources.
Methods for Cleanup: Absorb with inert material such as sand, earth, or vermiculite. Transfer spilled material to a secure, sealable container for proper disposal.
Reference to Other Sections: See heading on exposure controls and personal protection.
Handling: Use in a well-ventilated area. Keep away from ignition sources, sparks, and open flames. Avoid excessive heat. Prevent formation of aerosols. Utilize explosion-proof equipment.
Storage Conditions: Store in a cool, dry, well-ventilated place. Keep container tightly closed. Store away from direct sunlight, incompatible materials like strong acids, bases, and oxidizers.
Storage Incompatibilities: Do not store with oxidizing agents, strong acids, alkalis.
Special Precautions: Use appropriate earth and ground devices when transferring liquids. Keep containers tightly sealed.
Exposure Limits: No ACGIH or OSHA limits established, best practice: minimize exposure
Engineering Controls: Use local exhaust ventilation to maintain airborne concentrations below recommended limits. Use fume hoods when possible.
Personal Protective Equipment: Safety goggles, chemical-resistant gloves (nitrile or neoprene), lab coat, flame-resistant clothing.
Respiratory Protection: Use properly fitted air-purifying respirator with organic vapor cartridges for airborne exposures.
Hygiene Measures: Wash hands and other exposed areas with mild soap and water before breaks and after work. Remove contaminated clothing; launder prior to reuse.
