The following information is for people that are using carbon tetrachloride (CTC) in research labs. If you work at the University of Iowa and have questions about using CTC in areas besides labs please contact the EHS Industrial Hygienist.
Carbon tetrachloride, also known as carbon tet, tetrachloromethane, and CTC, is a Colorless liquid with a characteristic ether-like odor used in both laboratory and workshop settings. CTC can cause liver cancer, and damage the liver, kidney, and central nervous system. Because of the risk associated with CTC the EPA, under the Toxic Substance Control Act (TSCA) issued a regulation for the manufacturing and use of CTC. Including specific requirements for the use of CTC in labs.
The EPA Risk Management Rule for CTC requires people using CTC in a lab to do the following:
- Use CTC in a fume hood or glove box at all times.
- Use dermal protection that is impervious to CTC. Disposable latex and nitrile gloves are not impervious to CTC.
- Document and keep records of:
- Potentially exposed individuals and what dermal PPE they are using (This will be documented through the site-specific training form).
- Any occurrence of direct dermal contact with CTC. (This will done through the First Report of Injury Form).
