Naval Station Everett was established during a period when asbestos was widely used in naval and commercial shipbuilding. Several government agencies, including the U.S. Department of Health and Human Services (HHS), the International Agency for Research on Cancer (IARC), and the Environmental Protection Agency (EPA) have classified asbestos as a known human carcinogen. These agencies have likewise said that there is no safe threshold of asbestos exposure to be found. If you or someone you know served or worked at Naval Station Everett, you will need to undergo a full medical exam, which will likely involve a chest X-ray and a lung function test.
