Pyrospray — Keene Corporation
Product Description
Pyrospray was a spray-applied fireproofing and insulation product manufactured by Keene Corporation. Products marketed under the Pyrospray name were designed for use in industrial and commercial construction settings where fire resistance and thermal insulation were required across a variety of applications. Keene Corporation, headquartered in the United States, operated across multiple industrial sectors and produced a range of building materials and specialty products throughout much of the twentieth century.
The Pyrospray line was associated with several distinct product categories, reflecting the broad scope of Keene’s industrial materials business. According to litigation records, Pyrospray products were used or specified in contexts involving spray-applied fireproofing, pipe insulation, floor tile, refractory materials, and components related to valves and steam traps. This range of applications meant that Pyrospray materials could be encountered across a wide variety of industrial facilities, manufacturing plants, power generation stations, shipyards, and commercial construction sites.
Spray fireproofing products of the type associated with Pyrospray were applied to structural steel, beams, columns, and other building components to meet fire resistance standards in effect during the mid-twentieth century. Refractory applications addressed high-temperature environments such as furnaces, boilers, and kilns, where both heat resistance and insulating properties were critical to safe and efficient operation. Pipe insulation products helped manage temperature control and condensation in industrial piping systems, including those carrying steam, hot water, or process chemicals.
Asbestos Content
Pyrospray products manufactured by Keene Corporation have been identified in litigation as containing asbestos. During the period when these products were manufactured and distributed, asbestos was widely incorporated into fireproofing, insulation, and refractory materials because of its thermal stability, fiber strength, and resistance to heat and chemical degradation. Chrysotile asbestos, the most commonly used commercial form, as well as amphibole varieties, were routinely combined with binders, aggregates, and other materials to produce sprayed insulation and fireproofing compounds.
Plaintiffs alleged that Keene Corporation incorporated asbestos into Pyrospray formulations across multiple product categories. In spray fireproofing applications, asbestos fibers provided the heat-resistant matrix necessary to protect steel structures. In pipe insulation and refractory products, asbestos contributed both insulating value and structural integrity under thermal stress. The presence of asbestos in floor tile and valve or steam trap components reflects broader industry practices of using asbestos-containing materials wherever fire resistance, compressive strength, or thermal protection was commercially advantageous.
No specific asbestos percentage has been independently confirmed in publicly available regulatory documentation specifically for Pyrospray; however, litigation records document allegations that these products contained asbestos at concentrations sufficient to release respirable fibers under conditions of normal use, installation, and disturbance.
How Workers Were Exposed
Industrial workers across a range of trades and job classifications were potentially exposed to asbestos fibers released from Pyrospray products during manufacture, installation, maintenance, repair, and removal operations. Litigation records document claims from workers who alleged occupational contact with Keene Corporation’s Pyrospray line in industrial settings.
Spray Application Workers who applied Pyrospray fireproofing to structural steel and building components worked in conditions where asbestos-laden material was aerosolized directly. Spray application inherently creates fine airborne particulates, and where those materials contained asbestos, fiber concentrations in the breathing zone could reach significant levels without appropriate respiratory protection.
Pipefitters, Insulators, and Boilermakers encountered Pyrospray pipe insulation during installation on new construction as well as during maintenance and repair of existing systems. Cutting, fitting, and finishing asbestos-containing insulation around pipes and boiler components could release fibers into enclosed or poorly ventilated spaces.
Refractory Workers and Furnace Technicians who installed, repaired, or replaced refractory linings containing asbestos-based materials were exposed during both application and demolition work. High-temperature environments could also degrade binder materials over time, making aged refractory products friable and more likely to release fibers during disturbance.
Maintenance and Trades Workers who performed routine maintenance in industrial facilities where Pyrospray products had been installed faced secondary exposure. Drilling into coated steel, disturbing pipe insulation during system repairs, or working near deteriorating fireproofed surfaces could release fibers into the ambient air without the worker being directly engaged in asbestos-related tasks.
Floor Tile Installers and Removal Workers potentially encountered asbestos during the installation of Pyrospray floor tile products, particularly during cutting, grinding, or sanding operations, and during abatement or renovation work where existing tile was broken up or removed.
Plaintiffs alleged that Keene Corporation knew or should have known of the hazards associated with asbestos-containing products and failed to provide adequate warnings or instructions to workers and downstream users. Litigation records document claims that asbestos fibers released from Pyrospray products contributed to diagnoses of mesothelioma, asbestosis, lung cancer, and other asbestos-related diseases in workers with documented exposure histories.
Documented Trust Fund / Legal Options
Keene Corporation faced substantial asbestos liability arising from its manufacture and distribution of Pyrospray and other asbestos-containing products. The company’s asbestos litigation history is extensive, and Keene’s liability has been addressed through legal proceedings over multiple decades.
No Keene Corporation asbestos bankruptcy trust is currently identified as actively accepting claims. Unlike some other asbestos defendants that resolved liability through Chapter 11 reorganization and the establishment of a Section 524(g) trust, Keene Corporation’s asbestos liability was handled through a different legal framework. Individuals with claims related to Keene Corporation products, including Pyrospray, should consult with a qualified asbestos attorney to evaluate available legal remedies, which may include civil litigation against successor entities, insurance-based recovery, or claims against other responsible parties in the exposure chain.
Multi-Defendant Exposure Claims are common in asbestos litigation, and workers exposed to Pyrospray in industrial settings frequently worked alongside other asbestos-containing products from different manufacturers. An attorney experienced in asbestos litigation can assess the full exposure history and identify all potentially liable parties, including manufacturers, distributors, contractors, and premises owners.
Trust Fund Claims Against Other Defendants may be available if exposure involved asbestos-containing products from manufacturers who did establish bankruptcy trusts. Many industrial workers with Pyrospray exposure also encountered products from other manufacturers, and separate trust claims may be filed concurrently with civil litigation.
Individuals diagnosed with mesothelioma, lung cancer, asbestosis, or other asbestos-related conditions who have a history of working with or around Pyrospray products manufactured by Keene Corporation should seek legal consultation promptly. Statutes of limitations vary by state and typically run from the date of diagnosis or the date a reasonable person would have connected the diagnosis to asbestos exposure. Early legal consultation preserves the full range of available options.
