Inhalation: Move person to fresh air. Watch for signs of irritation, dizziness, or breathing difficulty. Seek medical advice if symptoms persist.
Skin Contact: Wash exposed skin thoroughly with soap and water. Remove contaminated clothing. Sensitive skin may benefit from applying a gentle moisturizer.
Eye Contact: Flush gently with water for at least 15 minutes. Remove contact lenses after the initial flush if present and easy to do.
Ingestion: Rinse mouth with water. Consult a healthcare provider if more than small amounts are ingested or symptoms develop.
Advice for Medical Responders: Treat symptoms. Give supportive care as needed.
Suitable Extinguishing Media: Use water spray, dry chemical, CO2, or foam
Unsuitable Media: High-powered water jet can spread liquid
Fire Hazards: Low fire hazard; thermal decomposition may generate carbon monoxide and carbon dioxide
Protective Equipment: Firefighters need self-contained breathing apparatus and protective gear
Special Procedures: Move containers from fire area if safe. Spray water to cool exposed containers, avoid run-off contamination
Combustion Products: Carbon oxides, potentially irritating fumes
Personal Precautions: Wear protective gloves, goggles, and use proper ventilation
Environmental Precautions: Prevent entry into soil, drains, or waterways. Use dikes or absorbent material around spills.
Spill Cleanup: Absorb with earth, sand, inert material. Use shovels to collect residue into sealable containers.
Disposal of Waste: Handle collected waste according to applicable local environmental regulations.
Preventive Actions: Avoid vapors and skin contact during cleaning up.
Handling: Keep containers tightly closed. Avoid splashing and minimize vapor generation. Use with adequate ventilation. Wear appropriate personal protection. Wash hands before eating, drinking, or smoking. Avoid practices that create aerosols.
Storage: Store in tightly sealed drums or containers, preferably in well-ventilated, cool, dry, and shaded areas. Protect from heat and incompatibles such as strong oxidizers. Avoid contact with open flames or sparks. Keep away from food products and out of children's reach.
Incompatible Materials: Strong acids, strong bases, oxidizers
Engineering Controls: Work with local exhaust ventilation or fume hood to reduce airborne concentration
Personal Protection: Chemical splash goggles, nitrile or neoprene gloves, protective clothing as required
Respiratory Protection: Not usually needed in well-ventilated areas; use half-face respirator with organic vapor cartridge if misting occurs or ventilation inadequate
Hygiene Measures: Do not eat, smoke, or drink during handling. Wash hands after handling.
Exposure Limits: Not established for TPG; base controls on general industry guidelines for glycols
Environmental Protection: Keep out of water, soil, and drains as good chemical hygiene practice
