Commercial Vinyl Flooring (Congoleum Corporation, 1974–1977)

Product Description

Congoleum Corporation was a major American manufacturer of resilient flooring products throughout the twentieth century, producing vinyl and vinyl-composition flooring for residential, commercial, and industrial markets. During the mid-1970s, the company manufactured a line of commercial vinyl flooring products intended for use in high-traffic environments such as warehouses, factories, retail spaces, and institutional facilities.

Commercial vinyl flooring of this era was designed to withstand the demands of industrial and commercial settings. The flooring was typically produced in sheet or tile form, offering durability, ease of cleaning, and resistance to moisture and physical wear. Congoleum’s commercial-grade products were marketed to contractors, building owners, and facility managers who required flooring that could perform reliably under continuous use. These products were installed throughout the United States during the years they were manufactured, meaning they remain present in older buildings today and can still pose a hazard during renovation, demolition, or maintenance work.

The production window for this specific product line has been identified in litigation and regulatory records as spanning approximately 1974 through 1977, a period during which the use of asbestos in flooring materials was still common across the industry, though regulatory pressure was beginning to mount following increasing awareness of asbestos-related health hazards.

Asbestos Content

Commercial vinyl flooring manufactured by Congoleum Corporation during this period contained chrysotile asbestos, the most commonly used form of asbestos in the flooring industry. Chrysotile, sometimes referred to as “white asbestos,” is a serpentine mineral fiber that was valued by manufacturers for its flexibility, tensile strength, and resistance to heat and chemicals — properties that made it well-suited to the production of resilient flooring products.

In vinyl and vinyl-composition flooring of this type, chrysotile fibers were typically incorporated into the backing layer or the body of the tile or sheet material itself. Asbestos served as a reinforcing agent, stabilizing the flooring matrix and improving the product’s performance characteristics under load and temperature variation.

It is important to note that chrysotile asbestos, despite being classified separately from the amphibole forms of asbestos, has been classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and is regulated as a hazardous substance under the Asbestos Hazard Emergency Response Act (AHERA) and OSHA’s asbestos standards (29 CFR 1910.1001 and 29 CFR 1926.1101). No form of asbestos has been established as safe at any level of occupational exposure.

How Workers Were Exposed

The workers most directly associated with exposure to asbestos from this product category are industrial workers generally — a broad designation that reflects the wide range of occupations present in the commercial and industrial facilities where this flooring was installed and later disturbed.

Asbestos fibers in resilient flooring products are largely stable when the flooring is intact and undisturbed. The risk of fiber release — and therefore the primary route of occupational exposure — arises during activities that physically disturb the material. Litigation records document that workers involved in the installation, cutting, sanding, scraping, grinding, or removal of commercial vinyl flooring products of this type were at potential risk of inhaling or ingesting airborne asbestos fibers.

Specific exposure scenarios documented in litigation and regulatory contexts include:

  • Cutting and trimming sheet or tile flooring to fit installation areas, which can release fibers from cut edges
  • Dry scraping or grinding of old flooring during removal or renovation, which can generate significant fiber concentrations
  • Sanding or buffing of flooring surfaces with abrasive equipment, disturbing the asbestos-containing matrix
  • Demolition activities in facilities where this flooring remained in place, often without workers being informed of the asbestos content

Industrial facilities presented particular exposure risks because workers in those environments often used heavy equipment, performed frequent floor maintenance, and operated in spaces where mechanical wear could gradually degrade flooring materials over time, potentially releasing fibers into the work environment. Additionally, workers in adjacent trades — maintenance personnel, electricians, pipefitters, and others working in the same spaces — could have been exposed to fibers released by primary flooring work, a phenomenon sometimes referred to as bystander or para-occupational exposure.

OSHA’s asbestos standards require employers to evaluate flooring materials that may contain asbestos before any disturbance activity begins, and mandate specific engineering controls, respiratory protection, and work practice controls when asbestos-containing flooring is disturbed. These requirements reflect the documented hazard associated with disturbing chrysotile-containing flooring materials.
