The O-class submarines were designed for coastal defense, and the USS O-7 making no exception. It was launched on 16 December 1916 and went through both World War I and World War II. Due to the fact that it was once decommissioned, asbestos may have lurked inside of it after 1941, so those who served after this year should pay close attention to symptoms that could indicate a disease like mesothelioma or lung cancer. The submarine was decommissioned on 11 July 1945 and sold for scrap one year later.
Asbestos was considered a miracle material for shipbuilding due to its durability, low cost and heat resistance and fireproof capabilities. Unfortunately, almost all of the effects of asbestos result in long-lasting effects on the human body. Depending on how long you have been exposed to asbestos, these long-lasting health effects can worsen over time and even contribute to severe illnesses and even early death.
