BOF Cote (Keene Corporation)

Product Description

BOF Cote was an industrial coating or protective compound manufactured by Keene Corporation, a company whose product lines spanned multiple construction and industrial material categories during the mid-to-late twentieth century. The name “BOF Cote” suggests an application in basic oxygen furnace (BOF) environments or similarly high-temperature industrial settings, consistent with Keene’s broader manufacturing profile, which included refractory materials, fireproofing compounds, and specialty industrial coatings designed to withstand extreme thermal and mechanical stress.

Keene Corporation operated across a notably wide range of product categories during its years of active manufacturing. The company produced or distributed materials that fell under floor tile, pipe insulation, refractory compounds, spray fireproofing, and valve and steam trap applications — a breadth that placed Keene products throughout industrial facilities, power plants, shipyards, chemical plants, and heavy manufacturing environments. BOF Cote, as part of this product family, would have been formulated and marketed for use in demanding industrial contexts where standard protective coatings were insufficient.

Keene Corporation became a significant defendant in asbestos personal injury litigation, with plaintiffs across multiple decades alleging exposure to asbestos-containing materials manufactured or distributed under the Keene name. The company’s history with asbestos litigation ultimately contributed to its financial restructuring, and Keene products appear across a substantial body of occupational exposure claims filed by industrial workers.

Asbestos Content

The specific formulated asbestos content of BOF Cote has not been independently published in available regulatory or product specification records accessible for this article. However, Keene Corporation’s broader product lines are extensively documented in asbestos litigation records as having contained asbestos mineral fibers in numerous product categories, including refractory coatings, fireproofing sprays, pipe insulation materials, and specialty industrial compounds.

Litigation records document that plaintiffs alleged BOF Cote and related Keene industrial products contained asbestos as a functional ingredient. In high-temperature industrial coating applications — particularly those associated with steel-making environments such as basic oxygen furnace operations — asbestos was a commonly used additive during the decades of Keene’s peak production. Asbestos fibers provided thermal resistance, structural reinforcement, and binding properties that manufacturers of the era considered essential for products designed to perform under sustained extreme heat conditions.

The types of asbestos fiber most commonly documented in industrial coatings and refractory materials of this period include chrysotile, amosite, and crocidolite, though the specific fiber types present in BOF Cote formulations are not independently confirmed in records available for this article. Plaintiffs alleged that whatever asbestos-containing formulation was used, it was capable of releasing respirable fibers during normal application, disturbance, and removal processes.

How Workers Were Exposed

Industrial workers represented the primary population documented in litigation and occupational health records as having been exposed to BOF Cote and similar Keene industrial products. Given the product’s apparent application in heavy industrial environments, the range of workers potentially affected was broad.

In steel manufacturing and heavy industrial settings — including facilities operating basic oxygen furnaces — workers involved in the application, maintenance, repair, and eventual removal or demolition of refractory coatings and protective compounds were at risk of asbestos fiber inhalation. Litigation records document that plaintiffs alleged exposure occurred through multiple mechanisms common to industrial coating products:

Application exposure occurred when workers sprayed, brushed, troweled, or otherwise applied the product in its working state. Mixing dry or semi-dry compound formulations, in particular, could generate substantial airborne dust containing asbestos fibers.

Disturbance and maintenance exposure occurred when previously applied coatings were sanded, scraped, chipped, or otherwise disturbed during repair cycles. Hardened asbestos-containing coatings, when mechanically disrupted, can release fibers at concentrations that exceed occupational safety thresholds established in later OSHA standards.

Adjacent worker exposure was also documented in litigation records, with plaintiffs alleged to have been exposed not as direct applicators but as bystanders working in the same enclosed or semi-enclosed industrial spaces where BOF Cote or similar products were being applied or disturbed. Shipyard workers, pipefitters, boilermakers, ironworkers, and general industrial maintenance personnel have all been represented in litigation involving Keene industrial coatings and related product lines.

Removal and demolition exposure was particularly significant in litigation records. Workers tasked with stripping, abating, or demolishing structures or equipment previously treated with asbestos-containing coatings and refractory materials faced some of the highest documented exposure concentrations, often without adequate respiratory protection, particularly prior to the promulgation of modern OSHA asbestos standards and the AHERA regulatory framework.

Keene’s multi-category product presence — spanning floor tiles, pipe insulation, steam traps and valves, and fireproofing materials — meant that industrial workers in facilities using Keene products could face cumulative exposures from multiple product sources across a single work environment or career.
