Plumbers and pipefitters worked directly with asbestos pipe insulation, gaskets, and packing throughout their careers, making them one of the highest-exposure trades.

How Plumbers Were Exposed

The pipes they installed and repaired were allegedly covered in asbestos pipe lagging and insulating cement, and every valve, flange, and fitting was sealed with asbestos gaskets and packing. Pipefitters cut and fitted insulation, repacked valves, and worked side-by-side with insulators in power plants, refineries, ships, and buildings. Cutting asbestos pipe covering and gasket material was daily work.

The Asbestos Materials — and the Products They Came In

Exposure tracked to a handful of material types. Each links to products documented in the AsbestosIndex as allegedly asbestos-containing:

Pipe covering & lagging — cut, fitted, and torn out:

Block insulation — cut and wired onto fittings and vessels:

Insulating cement — mixed and troweled over fittings:

Gaskets & valve packing — cut, scraped off, and repacked:

Asbestos-cement pipe — sawed and drilled:

Take-Home Risk to Families

Like other dusty trades, plumbers carried asbestos fibers home on their clothing, skin, and tools — exposing spouses and children who never worked with asbestos. See take-home asbestos exposure.

If you worked as a plumber and were diagnosed with mesothelioma or another asbestos-related disease after exposure to asbestos on the job, you may have a legal claim.
