Cafco Spray Type 1

Manufacturer: United States Mineral Products Company Product Category: Spray Fireproofing Years Produced: 1954–1958 Asbestos Type: Chrysotile


Product Description

Cafco Spray Type 1 was a spray-applied fireproofing material manufactured by United States Mineral Products Company (USMP) beginning in 1954. The product belonged to the Cafco line, a brand that became widely recognized in the commercial and industrial construction sectors for its use in passive fire protection systems. Spray fireproofing products of this era were applied directly to structural steel members — beams, columns, and deck assemblies — to slow the transfer of heat during a fire event and prevent structural collapse.

During the postwar construction boom of the 1950s, demand for fireproofing materials increased significantly as the United States saw rapid growth in industrial facilities, office buildings, warehouses, and institutional structures. Cafco Spray Type 1 was designed to meet that demand, providing contractors with a product that could be applied quickly and efficiently to large spans of structural steel using compressed air spray equipment.

United States Mineral Products Company operated out of Stanhope, New Jersey, and was one of several manufacturers that produced asbestos-containing sprayed fireproofing materials during this period. The Cafco product line continued to evolve over the following decades, but the earliest formulations — including Spray Type 1 — incorporated chrysotile asbestos as a primary component of the mixture.

Cafco Spray Type 1 was produced during a relatively narrow window, from 1954 through 1958, after which the product formulation was updated or superseded by successor products in the Cafco line. Despite its limited production run, the material was applied in industrial and commercial construction projects across the country during this period, meaning it remained in place in affected structures for decades after application.


Asbestos Content

Cafco Spray Type 1 contained chrysotile asbestos, the most commonly used form of asbestos in commercial building products during the mid-twentieth century. Chrysotile, sometimes called “white asbestos,” is a serpentine mineral fiber that was valued for its heat resistance, tensile strength, and ability to bind with cementitious and mineral wool binders to create a cohesive, insulating matrix when sprayed onto surfaces.

In spray fireproofing applications, asbestos fibers served a structural function within the applied coating. The fibrous material helped the product adhere to steel substrates, resist cracking as buildings settled or experienced thermal cycling, and maintain the integrity of the protective layer over time. As a result, asbestos content in spray fireproofing products was typically substantial, not merely incidental.

Regulatory documentation and historical product testing from this era confirm that chrysotile was an intentional and functional ingredient in early Cafco formulations. The United States Environmental Protection Agency’s Asbestos Hazard Emergency Response Act (AHERA) regulations and associated guidance documents identify sprayed-on asbestos-containing materials applied to structural components as a category of significant concern in buildings constructed or renovated during this period, citing the potential for fiber release when such materials are disturbed, degraded, or removed.


How Workers Were Exposed

Industrial workers who worked in facilities where Cafco Spray Type 1 was applied — or who later worked in, maintained, or renovated those structures — faced potential exposure to airborne chrysotile asbestos fibers.

During the original application process, spray fireproofing work generated substantial airborne dust. Workers operating spray equipment mixed and applied the material in enclosed or partially enclosed spaces, and overspray was a routine feature of the process. Workers in adjacent trades — ironworkers, electricians, pipefitters, and laborers present on the same job site — could be exposed through secondary contact with airborne material, even if they were not directly involved in the fireproofing operation itself.

Litigation records document that exposure did not end when the application was complete. Because Cafco Spray Type 1 was applied to the structural skeleton of industrial facilities, maintenance workers, insulators, mechanics, and general laborers who performed work overhead — drilling, cutting, or otherwise disturbing ceilings, beams, or mechanical systems — were positioned to disturb the friable, asbestos-containing coating during the normal course of their duties. Friable asbestos-containing materials, when disturbed, can release respirable fibers into the breathing zone of nearby workers.

Plaintiffs alleged in litigation involving Cafco and similar spray fireproofing products that workers frequently had no knowledge that the material they were working around or disturbing contained asbestos, and that no adequate warnings were provided regarding the hazards of asbestos fiber inhalation. Industrial workers generally — including those in manufacturing plants, power facilities, and other heavy industrial settings where spray fireproofing was common — constitute the primary population documented in connection with this product.

Asbestos-related diseases associated with chrysotile exposure include mesothelioma (a malignant cancer of the lining of the lungs, abdomen, or heart), asbestosis (progressive scarring of the lung tissue), lung cancer, and other respiratory conditions. These diseases typically have latency periods of twenty to fifty years between initial exposure and clinical diagnosis, meaning workers exposed to Cafco Spray Type 1 in the 1950s may only have received diagnoses in recent decades.


Cafco Spray Type 1 is classified as a Tier 2 — Litigated product. There is no established asbestos bankruptcy trust fund associated with United States Mineral Products Company through which claims for this specific product can be filed at this time.

Litigation records document that claims involving USMP products, including spray fireproofing formulations from the Cafco line, have been pursued in the civil tort system. Plaintiffs alleged that United States Mineral Products Company knew or should have known of the hazards associated with asbestos-containing spray fireproofing materials and failed to adequately warn workers and end users of those risks.

Individuals diagnosed with mesothelioma, asbestosis, lung cancer, or related asbestos-caused diseases who have a documented work history involving exposure to Cafco Spray Type 1 or similar USMP spray fireproofing products may have legal options available to them, including:

  • Civil litigation against manufacturers, contractors, or building owners whose negligence or product liability may be established through evidence of exposure
  • Workers’ compensation claims, depending on state law and the circumstances of occupational exposure
  • Claims against other asbestos trust funds, if co-exposure to products from other manufacturers whose successor entities have established trusts can be documented

Because asbestos litigation is highly fact-specific and involves questions of exposure history, medical diagnosis, and applicable statutes of limitations, individuals seeking to understand their legal options should consult a qualified asbestos attorney. Many asbestos litigation firms work on a contingency fee basis and offer free case evaluations for diagnosed individuals and their families.
