Keene Vinyl Asbestos Floor Tile

Product Description

Keene Corporation was a diversified industrial manufacturer whose product lines spanned multiple sectors, including construction materials, pipe insulation, refractory products, spray-applied fireproofing, and valve and steam trap assemblies. Among the building materials Keene produced were vinyl asbestos floor tiles, a flooring product widely specified for commercial, institutional, and industrial construction projects during much of the twentieth century.

Vinyl asbestos floor tiles were a standard specification item in American construction from roughly the 1950s through the late 1970s. Architects, contractors, and facility managers favored the product for its durability, resistance to moisture and heavy foot traffic, low cost, and ease of installation. The tiles were manufactured in standard dimensions—most commonly nine-inch and twelve-inch squares—and were installed using solvent-based adhesives, which themselves sometimes contained asbestos. The finished tile presented a hard, relatively smooth surface that was well suited to factories, schools, hospitals, office buildings, government facilities, and military installations.

Keene’s involvement in the asbestos products market was not limited to floor tile. Litigation records document that the company manufactured or distributed a range of asbestos-containing products across several industrial categories, including pipe insulation, refractory materials, spray fireproofing compounds, and valves and steam traps. This breadth of product involvement placed Keene’s materials in a wide array of work environments and exposed a correspondingly broad population of workers and tradespeople over many decades.

Asbestos Content

Vinyl asbestos floor tiles derived their name directly from their composition. Asbestos fibers—most commonly chrysotile, though litigation records document that other fiber types were used across the industry—were blended into a vinyl resin matrix during manufacturing. The asbestos content in vinyl floor tiles typically constituted a substantial portion of the tile by weight, with industry formulations commonly ranging from roughly 12 to 35 percent asbestos fiber, depending on the manufacturer, product line, and era of production.

The asbestos fibers served specific functional purposes in tile manufacturing. They provided tensile reinforcement to the vinyl matrix, increased dimensional stability, improved resistance to indentation under heavy loads, and contributed to the product’s fire resistance characteristics. From a manufacturing standpoint, asbestos was considered an ideal additive because it was inexpensive, widely available, and enhanced multiple performance properties simultaneously.

Plaintiffs alleged in litigation involving Keene that the company was aware, or should have been aware, of the hazards associated with asbestos fiber exposure well before warnings were incorporated into product labeling or manufacturing practices were modified. Litigation records document that internal industry knowledge about the health risks of asbestos inhalation predated widespread public disclosure by many years, and that manufacturers continued producing asbestos-containing products during periods when that knowledge was available within the industry.

How Workers Were Exposed

Vinyl asbestos floor tile presented exposure risks primarily during activities that disturbed the tile matrix—most significantly cutting, grinding, sanding, buffing, and demolition. When intact and undisturbed, the encapsulated asbestos fibers in a finished tile posed a lower immediate inhalation risk. However, the work of installing, maintaining, stripping, and removing vinyl asbestos floor tile routinely involved exactly the kinds of mechanical disruption that liberated respirable asbestos fibers into the air.

Installation workers and floor layers were among those most directly exposed. Cutting tiles to fit irregular spaces required scoring and snapping, or cutting with mechanical saws, both of which could release fiber. Fitting tiles around pipes, columns, and fixtures demanded repeated cutting and trimming throughout a workday.

Industrial workers generally in facilities where vinyl asbestos floor tile had been installed faced ongoing exposure risks from maintenance activities. Routine floor maintenance—including machine buffing and scrubbing—could abrade the tile surface and release fibers. Stripping old finish coatings using abrasive pads or chemical strippers, particularly in preparation for refinishing, was identified in litigation records as a significant source of fiber release. Workers performing these tasks often did so without respiratory protection and in poorly ventilated spaces.

Demolition and renovation workers encountered some of the highest exposure concentrations. Removing vinyl asbestos floor tiles—particularly tiles that had been glued down with adhesive and had become brittle with age—involved prying, chipping, and breaking the tile, generating substantial dust. Power equipment used to scrape adhesive residue from substrates could also aerosolize asbestos-containing material. Plaintiffs alleged in numerous cases that workers tasked with tile removal were not informed that the tiles contained asbestos and were not provided with appropriate protective equipment or decontamination procedures.

Because Keene also manufactured pipe insulation, refractory products, spray fireproofing, and valve and steam trap components, industrial workers in heavy manufacturing, power generation, petrochemical, and shipbuilding environments could have encountered multiple Keene asbestos-containing products simultaneously within a single worksite. Litigation records document that this pattern of co-exposure—where a worker was exposed to asbestos from several different product categories across a career—is common in asbestos disease litigation and was alleged in claims involving Keene products.

The latency period for asbestos-related diseases, which can range from ten to fifty years between initial exposure and disease diagnosis, means that workers exposed to Keene vinyl asbestos floor tile and related products during the peak production decades of the mid-twentieth century may be receiving diagnoses today or in the years ahead.

Keene Corporation faced substantial asbestos litigation arising from its manufacture and distribution of asbestos-containing products across multiple product categories. Litigation records document that Keene was named as a defendant in a large volume of asbestos personal injury cases filed by workers and their families alleging diseases including mesothelioma, lung cancer, asbestosis, and other asbestos-related conditions.

Keene Corporation ultimately resolved its asbestos liability through bankruptcy proceedings, resulting in the establishment of the Keene Creditors Trust, which was created to compensate individuals injured by Keene asbestos-containing products. Claimants seeking compensation through the Keene Creditors Trust are generally required to demonstrate an asbestos-related diagnosis and establish product exposure consistent with Keene’s documented product lines.

Who may have legal options:

  • Industrial workers, maintenance personnel, floor layers, and demolition workers with documented exposure to Keene vinyl asbestos floor tile
  • Workers exposed to other Keene asbestos-containing products, including pipe insulation, refractory materials, spray fireproofing, or valves and steam traps
  • Family members of deceased workers who died from mesothelioma or another asbestos-related disease attributable to Keene product exposure

Steps for affected individuals:

Individuals who believe they were exposed to Keene asbestos-containing products and have received an asbestos-related diagnosis should consult with an attorney experienced in asbestos litigation and trust fund claims. Documentation of work history, job sites, product identification, and medical records is typically required to support a claim. Trust fund and litigation deadlines vary, and early consultation with qualified legal counsel is advisable.
