Asbestos has been classified as a known human carcinogen (a substance that causes cancer) by the U.S. Department of Health and Human Services (HHS), the U.S. Environmental Protection Agency (EPA), and the International Agency for Research on Cancer (IARC).
U.S. federal law (as of 2019) does not require persons who inspect, repair or remove asbestos-containing materials in detached single-family homes to be trained and accredited; however, some U.S. states and Canadian provinces do require this. Inspectors and workers who handle asbestos should be trained and accredited.
Visit the EPA website for more information about becoming a professional who inspects or handles asbestos in a home, including state regulations.
Visit the government of Canada's website for information about asbestos.
