Capco Asbestos Cement Pipe

Product Description

Capco Asbestos Cement Pipe was a manufactured piping product produced under the Capco brand and associated with ASARCO, a company historically involved in mining, smelting, and the processing of raw mineral materials including asbestos. The pipe was manufactured during a period spanning from approximately 1965 through the early 1980s, coinciding with the broader industrial era during which asbestos-reinforced cement products were considered standard construction and industrial materials.

Asbestos cement pipe of this type was widely used in applications requiring durable, corrosion-resistant conduit systems. Common uses included pressurized water distribution lines, sewer systems, industrial drainage infrastructure, and conduit for electrical and utility installations. The material was favored by engineers and contractors because the cement-asbestos composite offered structural rigidity, resistance to chemical degradation, and the ability to withstand varying temperatures and pressures. As a result, Capco pipe found its way into a broad range of industrial and municipal infrastructure projects during the decades it was produced.

By the late 1970s and into the 1980s, regulatory pressure and mounting scientific evidence about the health dangers of asbestos exposure began to force manufacturers to reconsider asbestos-containing formulations. Production of asbestos cement pipe in the United States declined significantly during this period, and ASARCO, like many other industrial manufacturers, eventually ceased production of asbestos-containing products as regulatory frameworks tightened under agencies such as the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA).

Asbestos Content

Capco Asbestos Cement Pipe was manufactured using chrysotile asbestos as its primary reinforcing fiber. Chrysotile, sometimes referred to as white asbestos, is the most commercially used form of asbestos and belongs to the serpentine mineral group. Its long, curly fiber structure made it particularly well suited for incorporation into cement matrices, where it improved tensile strength, flexibility, and overall durability of the finished pipe product.

In asbestos cement pipe manufacturing, chrysotile fibers were blended with Portland cement and water, then processed under pressure to form pipe sections of varying diameters and wall thicknesses. The resulting product contained a significant proportion of asbestos by weight, with chrysotile fibers distributed throughout the cement body rather than concentrated in any single layer or coating. This diffuse distribution meant that any mechanical disturbance of the pipe material — cutting, grinding, drilling, or breakage — had the potential to release asbestos fibers from throughout the structure of the pipe wall.

Chrysotile asbestos has been classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and is regulated as a hazardous material under OSHA’s asbestos standards (29 CFR 1910.1001 and 29 CFR 1926.1101). The Asbestos Hazard Emergency Response Act (AHERA) further established regulatory frameworks for managing asbestos-containing materials in ways consistent with protecting public health.

How Workers Were Exposed

Industrial workers who handled, installed, cut, or otherwise worked with Capco Asbestos Cement Pipe during its production years faced potential exposure to airborne chrysotile asbestos fibers. The nature of asbestos cement pipe work frequently required on-site modification of pipe sections to fit specific installation requirements, meaning that dry-cutting or abrasive cutting of pipe was a routine task.

When asbestos cement pipe is cut with power saws, angle grinders, or abrasive cutting wheels — methods commonly used in industrial and construction settings during the 1960s and 1970s — the mechanical action fractures the cement matrix and liberates asbestos fibers into the surrounding air. Workers in proximity to these operations, including pipe fitters, laborers, and industrial maintenance personnel, could inhale these airborne fibers before adequate respiratory protection or engineering controls were commonly required or enforced.

Beyond cutting operations, other routine handling activities presented exposure risks. Broken or cracked pipe sections, common in storage yards and job sites, could release fibers from fractured surfaces. Workers who loaded, unloaded, or transported pipe sections by hand were subject to surface fiber contact and incidental inhalation. In enclosed or poorly ventilated industrial environments, fiber concentrations could accumulate to levels well above those now established as permissible under current OSHA standards.

OSHA’s permissible exposure limit (PEL) for asbestos is currently set at 0.1 fibers per cubic centimeter of air as an eight-hour time-weighted average. During much of the period when Capco pipe was in production and active use, such protections were either absent or inconsistently enforced. Workers in industrial settings were often unaware of the respiratory hazards associated with asbestos-containing materials, and personal protective equipment specifically rated for asbestos fiber exposure was not yet a standard workplace requirement.

Diseases associated with occupational asbestos exposure include mesothelioma, a malignant cancer of the lining of the lungs, abdomen, or heart; asbestosis, a chronic scarring lung disease; lung cancer; and other asbestos-related pleural conditions. These diseases typically have latency periods of 20 to 50 years between initial exposure and clinical diagnosis, meaning that workers exposed to Capco pipe during the 1960s and 1970s may only now be receiving diagnoses.

There is no asbestos bankruptcy trust fund currently associated with Capco Asbestos Cement Pipe or ASARCO’s production of this specific product line for the purposes of asbestos disease compensation in the same manner as many other asbestos product manufacturers. Individuals seeking compensation for asbestos-related diseases connected to Capco pipe have pursued remedies through civil litigation in the tort system.

Litigation records document claims brought by workers and their survivors alleging that exposure to Capco Asbestos Cement Pipe caused serious asbestos-related diseases, including mesothelioma and related conditions. Plaintiffs alleged that manufacturers and distributors of asbestos cement pipe products were aware or should have been aware of the health hazards associated with asbestos exposure, and that adequate warnings were not provided to workers who handled these products during their working lives.

Plaintiffs have alleged that ASARCO’s involvement in the production or supply of asbestos-containing materials, including cement pipe products, contributed to occupational exposures that resulted in latent disease decades later. Litigation records document that such claims have been pursued in asbestos dockets across multiple jurisdictions, where asbestos civil litigation is actively administered.

Individuals diagnosed with mesothelioma, asbestosis, lung cancer, or other asbestos-related conditions who have a documented history of working with or near Capco Asbestos Cement Pipe should consult with an attorney experienced in asbestos litigation. Legal counsel can review work history records, medical documentation, and product identification evidence to determine whether a civil claim may be viable. Given the lengthy latency period of asbestos-related disease, statutes of limitations in asbestos cases are typically calculated from the date of diagnosis rather than the date of exposure, though applicable deadlines vary by jurisdiction and individual circumstances.
