INGALLS SHIPBUILDING 
Asbestos Exposure

Are Ingalls Shipbuilding Workers at a Heightened Risk?

In theory, almost anybody in the shipbuilding industry in the 20th century could be at risk. The vast tons of material insulated with asbestos in enclosed spaces on ships served as a particularly insidious hazard to workers and servicemen.

Asbestos was used almost everywhere, including heavily in boiler rooms, engine rooms and sleeping quarters. It was used as insulation, pipe covering, and used in the paint that covered ships. It is estimated that in some years about 1 in 500 shipyard workers were handling and installing asbestos insulation on a daily basis.

Exposure to asbestos at shipyards is not limited to spending great amounts of time on ships. Even those workers loading and unloading materials at ports and dry docks could have been heavily exposed. The boxes, crates, pallets and packing materials used to carry the products sometimes contained asbestos fibers.

Navy Shipyard Asbestos 

At the height of World War II, the estimated number of naval shipyard workers could have been as high as 1.7 million. Because asbestos was a critical element in the shipbuilding industry at the time, military veterans, particularly Navy Veterans, have been especially hard-hit by exposure-related diseases.

Many veterans are eligible for disability compensation, handled by the U.S. Department of Veterans Affairs (VA). However, veterans must prove that their condition is asbestos-related exposure and was caused during active military service. This can be difficult. Fortunately, veterans can follow another course of action.

In addition to applying for government benefits, military veterans and former shipyard workers in Mississippi can file lawsuits against negligent companies, including the manufacturers of asbestos-containing products. An estimated 30 percent of all mesothelioma lawsuits are filed by military veterans.

The Dangers of Shipyard Asbestos

The potential dangers of asbestos inhalation have been known for several decades now, though the full extent of the damage to the lives and families of former workers has yet to be seen. Many former Ingalls workers are treated for mesothelioma, asbestosis, lung cancer, and other respiratory diseases as a result of poor working conditions in the past.

Because of the delayed symptoms, and long latency period of diseases caused by asbestos products, many former Ingalls shipyard workers are still being diagnosed with illnesses caused by exposure many years ago. It can take up to 50 years after exposure for symptoms of mesothelioma or asbestosis to present themselves.

In a 2007 study published by Occupational & Environmental Medicine, which studied the death of 4,700 men and women who built and maintained ships, researchers observed “excess deaths” from mesothelioma and respiratory cancer, which they attributed to asbestos fibers at shipyards.

How Are Shipbuilding Workers Exposure to Asbestos?

Some Ingalls Shipyard workers, some who have worked under Northrop Grumman Corporation or Litton Industries, performed tasks on any number and variety of vessels. Researchers suggest the worst exposure occurred in engine rooms, mess halls and on painted decks. Further exposure occurred in shipways and dry docks. The following jobs also put shipyard workers in direct contact with asbestos:

• Shipfitters
• Machinists
• Pipefitters & Plumbers
• Electricians
• Boilermakers
• Painters

Below is a list of tasks that are known to expose shipyard workers to high levels of asbestos:

• Painting
• Welding
• Insulating
• Regular maintenance, repairs, overhauls and decommissions
• Off-loading cargo
• Material delivery
• Unpacking pallets and crates
• Boiler and pipe work
• On-board machining

Ingalls Shipyard Workers: Welding & Painting

When coupled with asbestos exposure, welding and painting may be the most hazardous jobs of all. During welding operations, hazardous vapors are produced from the heating of base metals.

Other fumes are released from metal coatings, finishes, and welding rods. Dangerous exposures increase greatly if welding is performed in a confined space. Some of the metals welded in shipbuilding operations that may be airborne and cause acute and chronic lung diseases include:

• Cadmium
• Iron Oxides
• Zinc Oxides—from zinc-enriched paints and galvanized steel.
• Chromium—released when welding stainless steels, or around certain paints.
• Welding Injuries—in welding rods.
• Beryllium

Like welding, painting inside a ship’s hull is often performed in confined spaces and tanks, thereby concentrating toxic fumes. The following materials may have been used by shipyard painters:

• Lead-based paints
• Anti-fouling paint
• Anti-rust paint
• Zinc chloride primer paints
• Copper-bottom paints
• Solvents
• Pigments

Asbestos-Related Illnesses & Symptoms

The hazardous dust of asbestos fibers can cause a number of serious diseases. Some of these diseases directly caused by asbestos exposure can include:

• Mesothelioma (a cancer of the tissue surrounding the lungs and other organs)
• Lung cancer
• Asbestosis (scarring of lungs)
• Possible cancers in other organs
  The signs and symptoms of these conditions may include the following:
• Pain in the side of the chest or lower back
• Shortness of breath
• Cough
• Fever
• Excessive sweating
• Fatigue
• Weight loss
• Trouble swallowing
