Blaw-Knox Company, headquartered in Pittsburgh, Pennsylvania, was a diversified industrial manufacturer producing structural steel components, industrial processing equipment, and specialized machinery for construction, shipbuilding, and industrial plant applications. Blaw-Knox equipment appeared in naval shipyard operations and in Navy facility and shipyard construction — with Navy workers and civilian shipyard employees encountering Blaw-Knox industrial equipment in Navy shipyard and construction applications.

Asbestos in Blaw-Knox Industrial Equipment

Blaw-Knox industrial equipment and structural products used asbestos-containing materials in some configurations:

  • Industrial equipment thermal insulation — Blaw-Knox process equipment and industrial machinery in shipyard and construction applications used asbestos insulation on heated surfaces and in equipment that operated at elevated temperatures
  • Structural gaskets and seals — Blaw-Knox equipment connections and structural assembly joints used asbestos-containing gaskets and sealing materials in applications where thermal performance was required
  • Shipyard material handling equipment — Blaw-Knox material handling and process equipment at naval shipyards used asbestos-containing insulation on heated components in shipyard industrial operations

Blaw-Knox equipment appeared in naval shipyard industrial operations:

  • Shipyard workers operating and maintaining Blaw-Knox industrial equipment at naval shipyards encountered asbestos in the equipment’s insulation and sealing materials during operation and maintenance
  • Navy civilian and military personnel in shipyard industrial areas where Blaw-Knox equipment operated were in the ambient environment of industrial spaces with asbestos-containing equipment

VA Claims

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure from industrial equipment operation and maintenance at naval facilities. Navy personnel who worked with Blaw-Knox and other industrial manufacturers’ equipment with asbestos-containing materials at naval shipyards and installations and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
