Cafco Heat-Shield Type 2

Product Description

Cafco Heat-Shield Type 2 was a spray-applied fireproofing material manufactured by United States Mineral Products Company. Produced during a narrow window from 1961 to 1962, this product belonged to a class of cementitious or fibrous spray fireproofing compounds that became widely adopted in commercial and industrial construction during the mid-twentieth century. Spray-applied fireproofing of this type was used to coat structural steel members — beams, columns, and decking — to increase their resistance to heat and delay structural failure in the event of a fire.

United States Mineral Products Company, operating under the Cafco brand, was a prominent manufacturer in the spray fireproofing market during this era. The Cafco product line became broadly specified by architects and construction engineers who required passive fire protection systems that could be applied efficiently across large areas of structural steel. Heat-Shield Type 2 represented one formulation within that product line, targeted at industrial applications where fire resistance ratings were a construction or code requirement.

Although the product’s documented production period covers only 1961 and 1962, spray fireproofing materials installed during those years remained in place — and potentially intact or disturbed — for decades afterward in industrial facilities, warehouses, manufacturing plants, and other structures of that era.


Asbestos Content

Cafco Heat-Shield Type 2 contained chrysotile asbestos as a primary component of its formulation. Chrysotile, sometimes referred to as white asbestos, is a serpentine-group mineral fiber that was extensively used in spray fireproofing products during the 1950s, 1960s, and into the 1970s because of its heat-resistant, binding, and insulating properties. When mixed into a wet slurry and sprayed onto structural steel surfaces, chrysotile fibers became embedded in the hardened coating, providing the thermal protection the product was designed to deliver.

Chrysotile asbestos has been classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and is regulated under federal law. The Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) both maintain regulatory frameworks governing occupational and environmental exposure to chrysotile fibers, including specific provisions under the Asbestos Hazard Emergency Response Act (AHERA) addressing asbestos-containing materials in buildings.

The presence of chrysotile in spray fireproofing materials like Cafco Heat-Shield Type 2 is consistent with industry practice during this production period, when asbestos content in such products commonly ranged from significant to predominant proportions of the total dry weight of the material.


How Workers Were Exposed

The principal occupational exposure pathway for Cafco Heat-Shield Type 2 was through inhalation of airborne asbestos fibers released during the product’s application, disturbance, or removal. Industrial workers generally represent the trade group documented in connection with this product, reflecting the industrial settings in which this particular formulation was specified and applied.

During application, workers operating spray equipment mixed and projected the asbestos-containing slurry onto structural steel surfaces in enclosed or partially enclosed industrial spaces. This process generated airborne fiber concentrations as excess material dried, overspray settled, and workers moved through application areas. Ventilation in industrial construction settings was often inadequate to control fiber concentrations, and respiratory protection was rarely used in the early 1960s, when the hazards of asbestos inhalation were not yet widely communicated to workers.

During subsequent disturbance, workers in facilities where Cafco Heat-Shield Type 2 had been applied could encounter asbestos fibers whenever the fireproofing was mechanically disturbed. Drilling, cutting, demolition, renovation, and maintenance activities that contacted or damaged spray-applied fireproofing released previously encapsulated fibers into the breathing zone of nearby workers. Because spray-applied fireproofing is a friable material — meaning it can be reduced to powder by hand pressure — it is considered among the higher-risk categories of asbestos-containing building materials under EPA and AHERA classifications.

During removal, workers tasked with abating or demolishing structures containing Cafco Heat-Shield Type 2 faced concentrated exposure risks, particularly before regulated asbestos abatement procedures were established in the 1970s and 1980s. Prior to OSHA’s asbestos standards and the EPA’s National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations for asbestos, removal of spray fireproofing was often performed without engineering controls, wet methods, or respiratory protection.

Diseases associated with occupational chrysotile asbestos exposure include mesothelioma, asbestosis, lung cancer, and other asbestos-related conditions. Latency periods for these diseases — particularly mesothelioma — commonly span twenty to fifty years from initial exposure, meaning workers exposed during the 1961–1962 production period and in subsequent years of disturbance may have received diagnoses in later decades.


Cafco Heat-Shield Type 2 is a Tier 2 product for purposes of legal claims, meaning no dedicated asbestos bankruptcy trust fund has been established specifically to compensate individuals exposed to this product. Legal remedies for documented exposure must be pursued through civil litigation in the tort system.

Litigation records document that United States Mineral Products Company and its Cafco brand products have been named in asbestos personal injury lawsuits filed by workers and their surviving family members. Plaintiffs alleged that exposure to Cafco-brand spray fireproofing products, including formulations containing chrysotile asbestos, caused serious and fatal asbestos-related diseases. Plaintiffs alleged that the manufacturer knew or should have known of the hazards associated with airborne asbestos fiber inhalation and failed to adequately warn workers of those risks or provide safety guidance that could have reduced exposures.

Litigation records document claims arising from industrial settings where spray-applied fireproofing was used, with plaintiffs identifying their work histories at specific facilities where Cafco products were applied or disturbed.

Individuals who believe they were exposed to Cafco Heat-Shield Type 2 and have received a diagnosis of mesothelioma, asbestosis, lung cancer, or another asbestos-related disease should consult with an attorney experienced in asbestos litigation. Building product identification — including brand names, application dates, and facility records — is a central element of such claims, and legal counsel can assist in gathering the documentation needed to establish exposure history.

Family members of deceased workers may also have standing to bring wrongful death claims depending on applicable state law and statute of limitations. Because latency periods for asbestos diseases are long, statutes of limitations in asbestos cases typically run from the date of diagnosis rather than the date of exposure, though this varies by jurisdiction.

No asbestos bankruptcy trust fund has been identified for United States Mineral Products Company in connection with Cafco Heat-Shield Type 2. All claims related to this product are therefore directed to civil litigation channels rather than trust fund submission processes.
