Safety and Regulatory Considerations
CAS 79-01-6 Trichloroethylene TCE is regulated in many countries due to health and environmental concerns
Proper ventilation, PPE, and disposal are required
Gradually being replaced in some applications with safer alternatives
Storage Guidelines:
- Store Trichloroethylene in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and ignition points.
- Keep the container tightly sealed when not in use to prevent evaporation and contamination.
- Recommended storage temperature: Between 5°C to 25°C (41°F to 77°F).
- Store in approved containers made of metal or high-density polyethylene (HDPE) that are resistant to solvents.
- Keep away from strong oxidizers, acids, alkalis, and reactive metals like aluminum and magnesium.
- Do not store near food, beverages, or drinking water supplies to avoid accidental contamination.
