The USS Dionysus (AR-21) was a repair ship that served the US Navy during World War II. The ship was launched as the Liberty Ship SS Faithful by Bethlehem-Fairfield Shipyard in October 1944 and acquired by the Navy the same month. During its short World War II service, the vessel was stationed at Eniwetok where it fulfilled its repair duties. It was decommissioned at San Pedro in January 1947. It was recommissioned in February 1952 and sent to join the Atlantic Fleet, serving out of the Naval Station Norfolk base until sometime in 1953 when it was relocated to the Caribbean and later, Newport, Rhode Island. Asbestos is a fibrous mineral that has been used as insulation and a fire retardant in a wide variety of products. Asbestos can produce dust that, when inhaled, becomes deposited in the lungs. Inhalation of asbestos fibers can cause or contribute to the development of serious illnesses including asbestosis (a fibrous scarring of the lungs), lung cancer, gastrointestinal cancer, and mesothelioma (a fatal asbestos-associated malignancy that starts in cells that line certain parts of the body, especially the chest or abdomen.), and other severe illnesses. Because the early symptoms caused by asbestos-related pulmonary conditions are similar to some less serious health problems, it is important to see a doctor for a correct diagnosis.
