Asbestos Exposure
Materials Containing Asbestos
Most insulation materials before the mid-1970s contained asbestos. Many other construction materials also contained asbestos. Some of the most common products were:
- Insulation on pipes
- Boiler insulation
- Insulating cements, plasters and joint compounds that came in powder form and created a lot of dust before being completely mixed with water
- Fireproofing spray insulation
- Firebrick and gunnite used for internal insulation of furnaces, boilers and other vessels
- Roof, floor and ceiling tiles
- Transite siding
- Brakes and clutches
Most Commonly Exposed Personnel
The following Navy personnel could have worked around asbestos:
- Boilermen
- Enginemen
- Firemen
- Machinist Mates
- Shipfitters
- Pipefitters
- Electrician's Mates
- Seabees (military construction)
- Civilian shipyard workers
Shipboard Exposure
Fire and engine rooms aboard ship typically had the highest exposure because of the insulation and refractory products necessary in these high-heat areas, but no area was considered safe. Pipe coverings throughout the ship were covered with asbestos lagging, and literally ran inches over the bunks in the sleeping quarters. In addition, ships crews generally lived and worked aboard ships during routine maintenance operations and sometimes while their ships were overhauled in dry docks over months long periods.
Shipyard Exposure
During World War II, large quantities of asbestos used by shipyards as they built, overhauled and decommissioned warships, exposed thousands of shipyard workers to its insidious effects. Based on statistics, working in an American shipyard during the war years was almost as deadly as fighting in the war itself. The combat death rate was roughly 18 per thousand service members. For every thousand wartime shipyard employees, about 14 died of asbestos-related cancer, and unknown numbers died of asbestosis or related complications.
In 1984, a medical survey of shipyard workers at Norfolk Naval Shipyard in Portsmouth, VA, showed that 79 percent of these workers exhibited signs of lung abnormalities consistent with asbestos exposure, while x-rays given to 90 wives of workers revealed 8 to 9 percent showed similar abnormalities.
