Cafco Blaze-Shield Type D

Product Description

Cafco Blaze-Shield Type D was a spray-applied fireproofing material manufactured by United States Mineral Products Company (USMP) and sold under the Cafco product line. Produced from approximately 1958 through 1971, Blaze-Shield Type D was one of several fireproofing formulations that USMP brought to the commercial and industrial construction market during the postwar building boom in the United States.

Spray-applied fireproofing products of this era were widely specified by architects and engineers seeking to protect structural steel from heat-induced failure in the event of a fire. Steel loses a significant portion of its load-bearing strength when exposed to high temperatures, and fire-resistive coatings applied directly to structural members were considered an efficient and cost-effective means of meeting building code requirements. Blaze-Shield Type D was marketed for use on steel beams, columns, decking, and other structural elements, particularly in industrial and commercial facilities where fire protection was mandated by code or required by insurers.

The product was applied by mixing the dry compound with water on-site and spraying the resulting slurry directly onto structural surfaces using pneumatic equipment. This method allowed rapid coverage of large areas and was favored on job sites where speed and economy were priorities. USMP positioned the Cafco Blaze-Shield line as a leading solution for passive fire protection, and the product was distributed across the United States during its years of production.

Asbestos Content

Cafco Blaze-Shield Type D contained chrysotile asbestos as a principal component of its formulation. Chrysotile, also known as white asbestos, is a serpentine-form asbestos mineral that was the most commonly used asbestos fiber type in commercial products throughout the twentieth century. In spray-applied fireproofing, chrysotile fibers provided several properties that manufacturers valued: the fibers were heat-resistant, contributed to the structural integrity of the applied coating, and helped bind other ingredients together during and after application.

Litigation records document that Blaze-Shield Type D contained asbestos in concentrations sufficient to generate significant airborne fiber levels during normal application and finishing operations. Plaintiffs alleged that USMP and its predecessors and successors incorporated asbestos into the Blaze-Shield product line without providing adequate warnings to workers or end users about the health hazards associated with asbestos fiber inhalation.

The use of asbestos-containing spray fireproofing was common industry practice from the late 1950s through the early 1970s. Regulatory attention to asbestos hazards in spray-applied materials increased substantially during this period, culminating in the U.S. Environmental Protection Agency’s 1973 prohibition on spray-applied asbestos-containing materials in most building applications under the Clean Air Act’s National Emission Standards for Hazardous Air Pollutants (NESHAP). USMP’s production of Blaze-Shield Type D with asbestos ended in 1971, consistent with the industry’s broader transition away from asbestos-containing spray fireproofing in advance of federal restrictions.

How Workers Were Exposed

Workers employed in industrial and construction settings were the primary population exposed to asbestos fibers from Cafco Blaze-Shield Type D. Litigation records document that exposure occurred through multiple pathways and affected several categories of workers, with industrial workers generally representing the most commonly identified exposed population in claims associated with this product.

The spray application process was the most significant source of fiber release. When the dry mix was combined with water and sprayed under pressure, the mechanical action of the spray equipment and the turbulent air movement on job sites caused asbestos fibers to become airborne. Workers operating spray equipment were directly in the path of overspray and off-gassing from freshly applied material. Nearby tradespeople — including ironworkers, pipefitters, electricians, and laborers — were also present in enclosed or partially enclosed spaces where fiber concentrations could accumulate.

After application, finishing operations such as brushing, troweling, or trimming excess material from edges and surfaces continued to release fibers. Plaintiffs alleged that the dry, friable nature of the cured product meant that any subsequent disturbance — whether during construction, maintenance, renovation, or demolition — could liberate asbestos fibers into the breathing zone of workers present at the time.

Industrial facilities where fireproofing was applied or later disturbed represented environments of continuing exposure risk. Maintenance workers, pipefitters, and general industrial workers who performed routine work around previously coated structural steel could disturb aged or damaged fireproofing material during the course of ordinary repairs or modifications, resulting in secondary exposures that were often unrecognized and uncontrolled.

Litigation records document that workers in these settings frequently lacked respiratory protection, were not informed that the materials they were working with or around contained asbestos, and received no training in safe handling procedures. Plaintiffs alleged that USMP was aware of the hazards associated with asbestos inhalation and failed to warn workers or provide adequate safety information about the risks of working with Blaze-Shield Type D.

Asbestos-related diseases associated with occupational inhalation of chrysotile fibers include mesothelioma, asbestosis, lung cancer, and other pulmonary conditions. These diseases are characterized by long latency periods, often decades, between initial exposure and clinical diagnosis, meaning workers exposed to Blaze-Shield Type D during its years of production may not have developed identifiable illness until many years after the product was discontinued.

Documented Trust Fund / Legal Options

Cafco Blaze-Shield Type D is classified as a Tier 2 litigated product. There is no established asbestos bankruptcy trust fund associated with United States Mineral Products Company that currently accepts claims for this product. Individuals injured by exposure to Blaze-Shield Type D do not have a trust fund filing pathway available to them and must pursue compensation through the civil litigation system.

Litigation records document that claims involving Cafco Blaze-Shield Type D have been filed in jurisdictions across the United States by workers and surviving family members seeking damages for asbestos-related diseases. Plaintiffs alleged negligence, failure to warn, and product liability on the part of USMP and, in some cases, premises owners, general contractors, and other parties responsible for worksite conditions during the period of asbestos exposure.

Individuals who believe they were exposed to Cafco Blaze-Shield Type D and who have received a diagnosis of mesothelioma, asbestosis, lung cancer, or another asbestos-related condition should consult a qualified asbestos litigation attorney. An experienced attorney can evaluate the specific facts of exposure, identify all potentially liable parties, assess applicable statutes of limitations, and advise on whether civil litigation in state or federal court is the appropriate legal avenue for seeking compensation.

Because USMP is not currently operating under a bankruptcy trust structure for this product, the viability and scope of litigation claims will depend on current corporate successor relationships, available insurance coverage, and jurisdiction-specific legal standards. Legal counsel with documented experience in asbestos product liability litigation is essential for navigating these complexities.
