Buck Stay Cement A-1360

Product Description

Buck Stay Cement A-1360 was a refractory cement manufactured by Combustion Engineering, Inc. during the period from approximately 1964 through 1970. Refractory cements of this type were specifically engineered to withstand extreme heat, and Buck Stay Cement A-1360 was designed for use in industrial furnaces, boilers, kilns, and other high-temperature processing equipment. The product belonged to a category of industrial construction and maintenance materials used extensively in heavy manufacturing, power generation, and chemical processing facilities throughout the United States during the mid-twentieth century.

Combustion Engineering, Inc. was a major industrial manufacturer with a broad product portfolio that included boilers, nuclear equipment, and a range of refractory and insulating materials used in industrial settings. Their refractory products, including Buck Stay Cement A-1360, were sold to industrial facilities and applied by workers engaged in the construction, installation, repair, and maintenance of high-temperature equipment. The name “Buck Stay” refers to structural components used in boiler construction—specifically the stays or braces that hold furnace wall sections in place—and the cement was formulated to seal, bond, and protect these structural assemblies under conditions of sustained thermal stress.

As with many refractory products manufactured during this era, Buck Stay Cement A-1360 was formulated with asbestos-containing materials, reflecting the widespread industry practice of incorporating asbestos into heat-resistant products throughout the mid-twentieth century.

Asbestos Content

Buck Stay Cement A-1360 contained chrysotile asbestos as a component of its formulation. Chrysotile, also known as white asbestos, is a serpentine-form asbestos fiber that was the most commercially prevalent variety used in industrial products during the twentieth century. Its heat resistance, tensile strength, and binding properties made it a commonly selected additive in refractory cements and similar materials intended for high-temperature applications.

In refractory cements, chrysotile asbestos served multiple functional purposes. It reinforced the structural integrity of the cured cement, helping it resist cracking and mechanical failure under repeated thermal cycling. It also contributed to the product’s insulating properties and its ability to maintain adhesion to metal and masonry surfaces in furnace and boiler environments. These characteristics made asbestos-containing refractory cements standard materials in heavy industrial settings during the period when Buck Stay Cement A-1360 was produced and marketed.

The presence of chrysotile asbestos in products like Buck Stay Cement A-1360 is significant from a health standpoint because chrysotile fibers, when disturbed or made airborne, can be inhaled and deposited in the lungs. Regulatory and scientific bodies, including the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), have established that all forms of asbestos, including chrysotile, are associated with serious and potentially fatal diseases including mesothelioma, asbestosis, and lung cancer. OSHA’s current permissible exposure limit for asbestos reflects the recognized hazard that even low-level, repeated exposure to asbestos fibers presents over time.

How Workers Were Exposed

Industrial workers who handled, mixed, applied, or worked in proximity to Buck Stay Cement A-1360 during the years of its production and use were potentially exposed to airborne chrysotile asbestos fibers. The nature of refractory cement work created multiple pathways for fiber release and inhalation.

Mixing dry refractory cement was among the most hazardous tasks associated with products of this type. Workers who opened bags of Buck Stay Cement A-1360, poured the material, and mixed it with water in preparation for application could generate visible dust clouds containing asbestos fibers. Without adequate respiratory protection—which was rarely standard practice at industrial facilities during the 1960s and early 1970s—these workers inhaled fibers directly during mixing operations.

Application of the cement to boiler wall assemblies, furnace linings, and buck stay structural components also created exposure opportunities. Troweling, spreading, and shaping the wet cement could disturb the asbestos fiber matrix, and any spattering or excess material that dried and was subsequently disturbed would release additional fibers. Workers in adjacent areas who were not directly handling the product could also be exposed through ambient airborne fiber contamination in enclosed industrial spaces.

Maintenance and repair activities presented ongoing exposure risks beyond the initial installation period. When Buck Stay Cement A-1360 cured and was subjected to thermal cycling, cracking and deterioration of the material were common. Workers tasked with chipping out and removing old or failed refractory cement, as well as those who cut, ground, or otherwise disturbed the hardened material during furnace or boiler overhauls, could release concentrated amounts of previously bound asbestos fibers. These maintenance activities, which often took place in confined spaces with limited ventilation, represented particularly high-exposure scenarios.

Industrial workers generally employed at power plants, steel mills, chemical plants, paper mills, and other facilities where boilers and furnaces required regular service were among those with documented potential for contact with Buck Stay Cement A-1360 and similar refractory products manufactured during this period.

No dedicated asbestos bankruptcy trust fund has been established specifically for claims arising from exposure to Buck Stay Cement A-1360 or other Combustion Engineering refractory products of this type in connection with this product line. Individuals who believe they have been harmed by exposure to this product should consult with an asbestos litigation attorney to evaluate the legal options available to them.

Litigation records document claims filed against Combustion Engineering and related corporate entities in connection with asbestos-containing products manufactured and sold under the Combustion Engineering name. Plaintiffs alleged that Combustion Engineering knew or should have known of the health hazards associated with asbestos-containing refractory products during the years these materials were manufactured and that the company failed to provide adequate warnings to workers and end users about the risks of asbestos fiber inhalation.

Plaintiffs alleged that exposure to Buck Stay Cement A-1360 and similar products contributed to the development of asbestos-related diseases including mesothelioma, lung cancer, and asbestosis, and that the absence of proper safety warnings and instructions deprived workers of the opportunity to protect themselves from fiber inhalation during mixing, application, and maintenance activities.

Individuals diagnosed with mesothelioma, asbestosis, lung cancer, or other asbestos-related conditions who have a documented history of working with or around Buck Stay Cement A-1360 between 1964 and 1970 may have grounds for civil litigation. Additionally, it is advisable to explore whether exposure to other asbestos-containing products used in the same work environments may support claims against other manufacturers’ established trust funds. Many workers were exposed to multiple asbestos products simultaneously, and asbestos litigation attorneys are experienced in identifying all potentially responsible parties and applicable compensation sources.

Consultation with a qualified asbestos attorney is recommended to assess the viability of individual claims, applicable statutes of limitations, and jurisdiction-specific legal procedures.
