Kaowool ceramic-fiber refractory blanket — Babcock & Wilcox

Product Description

Kaowool ceramic-fiber refractory blanket were manufactured under the Babcock & Wilcox name and supplied throughout the period when asbestos was the routine sealing and insulating material in refractory service. The Babcock & Wilcox catalog reached American industrial worksites, including power generation facilities, refineries, paper mills, shipyards, and major institutional construction projects.

According to asbestos litigation records, Kaowool ceramic-fiber refractory blanket were supplied to American industry through the period when asbestos was treated as the routine sealing and insulating material for high-temperature service. Babcock & Wilcox built its market position around durability and reliability under demanding conditions — the same operating envelope that drove asbestos use across the refractory category well into the late 1970s.

Asbestos Content

Court filings document allegations that Kaowool ceramic-fiber refractory blanket incorporated asbestos in one or more of the structural roles common to refractory of the era:

High-temperature refractory body — Asbestos fibers were incorporated into the refractory material as a binding, thermal-shock, and tensile-strength additive in formulations sold throughout the period before regulatory action.

Mixing and pre-installation handling — Workers mixing dry refractory generated airborne fiber during the mixing operation. Cutting and trimming refractory shapes for installation released additional fiber.

Replacement and demolition — Removing degraded refractory during outage work — chipping, jackhammer, or hand-removal — released large airborne fiber concentrations into the work area.

Adjacent insulation — Refractory installations were typically backed by asbestos-bearing insulating block or blanket, compounding exposure during installation and demolition.

The asbestos in these components was not unique to Babcock & Wilcox; the materials in question were industry-standard well into the 1970s. The relevance to litigation lies in the volume of Kaowool ceramic-fiber refractory blanket installed across American worksites and the frequency with which those components were disturbed during ordinary maintenance.

How Workers Were Exposed

Workers most likely to have encountered asbestos through Kaowool ceramic-fiber refractory blanket include those whose trades brought them into routine contact with the equipment:

  • Refractory installation crews — mixing, cutting, and installing refractory linings in furnaces and boilers
  • Boilermakers — repairing and rebuilding refractory on industrial boilers and furnaces
  • Steel-mill, foundry, and cement-kiln workers — replacing degraded refractory during outage work
  • Demolition crews — removing legacy refractory from decommissioned industrial equipment
  • Insulators — applying asbestos-bearing back-up insulation behind refractory linings

Court filings document that bystander and take-home pathways were also common. Workers who did not directly handle Kaowool ceramic-fiber refractory blanket but who shared confined work areas with those who did were alleged to have inhaled the same airborne fibers. Family members were exposed through fibers carried home on contaminated work clothing — a pathway recognized in occupational medicine and asbestos litigation as take-home or secondary exposure.

The latency period for asbestos-related diseases — mesothelioma, asbestosis, lung cancer, and pleural disease — ranges from roughly ten to fifty years between initial exposure and diagnosis. Workers exposed through Kaowool ceramic-fiber refractory blanket during the 1940s through the early 1980s may only now be receiving diagnoses tied to that occupational history.

The current trust-fund and litigation status for products in the Babcock & Wilcox catalog is summarized on the manufacturer reference page linked at the top of this article. Where a Section 524(g) trust exists, claims may be filed in parallel with civil litigation against other defendants whose products contributed to the same exposure history. Where no trust exists, claims are pursued through the civil court system. Statute-of-limitations rules vary by state and disease type; the limitations clock generally begins at the time of diagnosis rather than the time of exposure.

Individuals who worked with or around Kaowool ceramic-fiber refractory blanket and have been diagnosed with an asbestos-related disease should preserve documentation of employment history, jobsites, and product identification, and consult an attorney experienced in asbestos claims promptly after diagnosis.
