Tons of Asbestos on Navy Ships
Asbestos is a fibrous mineral that was extensively used in ship construction until the late 1970s. Thousands of tons of asbestos on Navy ships were used to wrap pipes, line boilers, and cover engine and turbine parts. Asbestos on Navy ships proved ideal because of its ability to resist corrosion and high temperatures. But its harmful effects would not only injure shipyard workers, but also Navy personnel, who are both now suffering from very high rates of asbestos-related disease. Here's some startling statistics:
- A study conducted at the Mt. Sinai School of Medicine found that 86 percent of asbestos shipyard workers with 20 or more years of experience have developed asbestos-related lung disease or lung cancer.
- Approximately 100,000 people in the U.S. have died, or will die, from asbestos on Navy ships.
- There were approximately 4.3 million asbestos shipyard workers during WWII; for every thousand workers about fourteen have died of mesothelioma and an unknown number died of asbestosis.
- Asbestos on Navy ships insulation sprayers, breathed as many as 100,000 fibers with every lungful of air at work—compared to today's OSHA 8-hour limit of 100,000-fibers.

Virtually no portion of a naval ship was asbestos-free between the '30s and mid-70s, making Navy veterans and asbestos shipyard workers one of the most at-risk groups for developing asbestos-related diseases.
Longshoreman Suffered Too from Asbestos Handling
Even longshoreman (those who load the ships) were heavily exposed to asbestos shipyards as well. Before the 1980s, many longshoremen loaded bundles of asbestos onto ships. The health risk associated with handling asbestos was not known by these unfortunate workers and no special precautions were taken to prevent inhalation.
