We use a formula to convert workplace limits to home limits. Most people can't smell 1,1,1-TCA until the level is greater than 100 ppm. If you can smell the chemical, the level is too high to be safe. The Wisconsin Department of Natural Resources regulates the amount of 1,1,1-TCA that can be released by industries. Animal studies show that exposure to 1,1,1-TCA is not likely to cause cancer.
Laboratory studies show no effect on reproductive systems or the developing fetus.
In general, chemicals affect the same organ systems in all people who are exposed. However, the seriousness of the effects may vary from person to person. A person's reaction depends on several things, including individual health, heredity, previous exposure to chemicals including medicines, and personal habits such as smoking or drinking. For those individuals with frequent or potentially high-level exposures, liver function tests and neurological examinations may be performed. A medical evaluation that includes a careful history of past and present symptoms will provide a basis for future health exams.
