The SS Harold O. Wilson was a Liberty Ship built by the United States to be used during World War II. It was named after the crewmember Harold O. Wilson who got lost at sea while serving on the SS Flora MacDonald which was torpedoed by a German submarine in 1943, near Sierra Leone. The ship was laid down at the J.A. Jones Construction’s shipyard in Brunswick, Georgia, in December 1943, under a Maritime Commission contract. It was renamed North Beacon and served under this name until it was sold in April 1955. The ship remained in service until it was wrecked and sold for scrapping in January 1961. An occupational disease is a health condition or disorder that occurs as a result of work or occupational activity. Daily contact with hazardous materials or substances at work can lead to serious health problems later in life. For instance, Navy veterans have a higher chance of developing mesothelioma, as a consequence of asbestos exposure which occurred while serving aboard ships. Asbestos is a natural silicate material consisting of long, glass-like fibers that are composed of millions of tiny fibroids. It's abundant and tough, and it won't burn, which meant to builders in the mid-20th century that it was ideal for insulation.
