Is perchloroethylene (CAS 127-18-4) harmful to humans?

may cause central nervous system effects leading to dizziness, headache, sleepiness, confusion, nausea, difficulty in speaking or walking, and possibly unconsciousness and death. It is a narcotic at high levels. Adverse liver and kidney effects have been observed in workers that had long term exposure to tetrachloroethylene. It will also defat the skin causing irritation and dryness. Worksafe Australia reports perchloroethylene is a 'suspected carcinogen'.

Tetrachloroethylene evaporates quickly and so the most common exposure is from breathing air containing it. It may also enter the body if we eat or drink food or water that has been contaminated. It does not pass through the skin.

1. Avoid inhaling its vapors during use. Maintain good ventilation during operation, using dehumidifiers or exhaust systems to remove CAS 127-18-4 perchloroethylene from the air, and wear appropriate respiratory protection equipment such as a gas mask or air-supplied breathing apparatus.

2. When handling tetrachloroethylene, wear protective gloves, safety glasses, or a face shield to avoid contact with skin, eyes, or other mucous membranes.

3. In case of ingestion or inhalation, seek immediate medical attention and bring the container or label to the hospital for proper diagnosis and treatment.

4. Perchloroethylene is toxic to aquatic life and should not be discharged into water bodies to prevent environmental pollution. Waste and residues should be properly disposed of in accordance with local environmental regulations.
