New Castle’s mills, foundries, and rail shops: asbestos exposure history

Tin and rolling mills, Johnson Bronze, the Universal-Rundle plants, and the rail yards at New Castle Junction and Mahoningtown: casting floors and heat-treat shops rather than blast furnaces. Reviewed by Michael C. Schafle, Esq.

New Castle is a Shenango Valley town, not a Mon Valley one. Its asbestos history comes from tin plate and rolling mills, bearing and bronze casting, sanitary ware, and railroad repair shops rather than from blast furnaces, and that changes which trades and which products turn up in a work history. It does not change the legal route. The National Cancer Institute reports that mesothelioma typically appears 20 to 50 years after exposure (NCI asbestos fact sheet), so the diagnoses being made in Lawrence County today trace back to shifts worked from the 1940s into the 1980s.

Where New Castle workers were exposed

The city’s tin mills and rolling mills ran on steam and heat, and everything that carried either was insulated with asbestos. Johnson Bronze made bearings and bushings in New Castle for most of the last century, which meant melt furnaces, casting floors, and heat-treat lines. The Universal-Rundle plants made plumbing fixtures with kilns and drying equipment that were lined and lagged the same way. Along the river and at New Castle Junction and Mahoningtown, the B&O and P&LE yards and repair shops serviced steam and then diesel locomotives whose boilers, brake systems, and gaskets contained asbestos. Railroad employees have their own federal route, the Federal Employers’ Liability Act, explained on our mesothelioma lawsuit pages.

The asbestos decades

Asbestos was standard in insulation for boilers, pipes, furnaces, and other high-heat equipment until the late 1970s. In New Castle that meant furnace and kiln linings, pipe covering on process lines, gaskets and packing in valves and pumps, welding and heat-treat blankets, brake and clutch linings in the rail shops, and the asbestos cloth that casting crews wore. Molders, furnace operators, machinists, pipefitters, millwrights, bricklayers, carmen, and boilermakers all worked in that dust, and the maintenance and reline crews who tore old insulation off were exposed most heavily of all.

Whose claims come out of New Castle

  • Molders, casting-floor laborers, and heat-treat and furnace operators
  • Tin mill and rolling mill hands
  • Kiln and drying-room workers at the sanitary ware plants
  • Railroad carmen, boilermakers, and shop machinists
  • Pipefitters, millwrights, bricklayers, and electricians who maintained all of it
  • Spouses and children exposed to fibers on work clothes, which the NCI identifies as a recognized exposure route

A multi-employer town

The New Castle pattern is a career that moved between the mills, the bronze shop, the fixture plants, and the rail yards. That makes the investigation longer, not weaker: each employer adds its own suppliers and, often, its own bankruptcy trusts. Careers also reached into the wider valley, including Sharon Steel to the north, and every plant in the history is worth listing.

Records that survive closed plants

Most of New Castle’s plants are gone, and the employer is rarely the defendant anyway. Claims are brought against the manufacturers of the products, and union records, Social Security earnings histories, co-worker testimony, and earlier litigation over the same brands can establish what a worker was around. Our asbestos trust funds pages explain how trust claims fit alongside a lawsuit.
