Cafco Power-Shield Spray Fireproofing (1964–1971)

Product Description

Cafco Power-Shield was a spray-applied fireproofing material manufactured by U.S. Mineral Products Company during the period from approximately 1964 through 1971. The product belonged to a broader family of cementitious and fibrous fireproofing compounds marketed under the Cafco brand name, which U.S. Mineral Products developed and sold primarily to the commercial and industrial construction sectors throughout the mid-twentieth century.

Spray-applied fireproofing of this era served a critical structural role: when applied to steel beams, columns, decking, and other load-bearing elements, the material was intended to slow heat transfer and preserve structural integrity during a fire event, buying time for evacuation and emergency response. The fireproofing was typically mixed on-site or delivered in a wet slurry form, then sprayed under pressure directly onto structural steel surfaces using specialized equipment.

U.S. Mineral Products Company was a New Jersey-based manufacturer that became one of the dominant suppliers of spray-applied fireproofing products in the United States. The Cafco product line—of which Power-Shield was one formulation—was sold to contractors working on commercial office buildings, industrial facilities, schools, hospitals, and other large-scale construction projects across the country during the postwar building boom. Cafco Power-Shield was specifically positioned as a product suitable for demanding applications where fire-resistance ratings were required by building codes or insurance standards.

Asbestos Content

Cafco Power-Shield, as manufactured during its production period from approximately 1964 to 1971, contained asbestos as a primary constituent material. Spray-applied fireproofing products of this generation relied heavily on asbestos fibers—most commonly chrysotile and, in some formulations, amosite—because asbestos offered a combination of properties that made it particularly well-suited to the application: it was heat resistant, relatively lightweight, capable of bonding to irregular surfaces, and cost-effective to process at industrial scale.

The asbestos fibers in products like Cafco Power-Shield functioned as reinforcing and insulating agents within the overall matrix of the compound. When properly applied and left undisturbed, the material adhered to steel substrates and formed a protective coating. However, the very properties that made asbestos fibers effective in this role—their microscopic size and durability—also made them hazardous when those fibers became airborne.

Litigation records document that U.S. Mineral Products Company had access to information concerning the health hazards associated with asbestos-containing fireproofing materials during the period in which Cafco Power-Shield was manufactured and sold. Plaintiffs have alleged that despite this knowledge, adequate warnings were not provided to workers, contractors, or building owners who used or were otherwise exposed to the product.

The production of asbestos-containing spray fireproofing by U.S. Mineral Products and other manufacturers was ultimately curtailed following regulatory action. The U.S. Environmental Protection Agency effectively restricted sprayed asbestos fireproofing applications beginning in the early 1970s, and subsequent federal regulations under AHERA (the Asbestos Hazard Emergency Response Act of 1986) established protocols for identifying, managing, and where necessary abating asbestos-containing materials including sprayed fireproofing in schools and public buildings.

How Workers Were Exposed

Workers exposed to Cafco Power-Shield during its period of manufacture and installation faced significant inhalation risks due to the nature of the spray application process. Industrial workers generally, along with those in related construction and maintenance trades, encountered the product in a variety of settings and circumstances.

During installation, spray fireproofing operations generated substantial quantities of airborne dust and fiber. Applicators who operated spray equipment worked in close proximity to the material as it was mixed and discharged, and overspray was a persistent feature of the worksite environment. Because large-scale steel construction projects often involved multiple trades working in the same spaces simultaneously, ironworkers, electricians, pipefitters, plumbers, sheet metal workers, and laborers who were present during or immediately after fireproofing operations could also be exposed to airborne fibers even if they had no direct involvement with the spray process itself.

Litigation records document that conditions on many job sites during this era provided minimal respiratory protection for workers. Plaintiffs have alleged that employers, contractors, and product manufacturers failed to implement adequate dust controls, failed to require or provide appropriate respirators, and failed to warn workers that the fireproofing materials they were working around contained hazardous asbestos fibers.

Exposure was not limited to the original installation period. In industrial settings, maintenance and repair activities—including welding, cutting, grinding, or disturbing structural steel members coated with Cafco Power-Shield—could release previously bound asbestos fibers back into the breathing zone of workers. Renovation and demolition of structures built during the 1964–1971 production window created additional exposure scenarios decades after the original application. Plaintiffs have alleged that this secondary exposure—encountered by workers who may have had no knowledge that the fireproofing material they were disturbing contained asbestos—caused serious and preventable illness.

Diseases associated with occupational asbestos exposure and documented in litigation involving spray fireproofing products include mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease. These conditions typically have latency periods of ten to fifty years, meaning workers exposed to Cafco Power-Shield during its production years may not have developed symptoms until decades later.

Because U.S. Mineral Products Company is a Tier 2 product manufacturer with respect to litigation history rather than a trust fund resolution, individuals seeking legal remedies in connection with Cafco Power-Shield exposure pursue claims through the civil court system rather than through an established asbestos bankruptcy trust.

Litigation records document that U.S. Mineral Products Company has been named as a defendant in asbestos personal injury and wrongful death lawsuits filed by former industrial workers and others who alleged exposure to Cafco and related spray fireproofing products. Plaintiffs in these cases have alleged negligence, failure to warn, and product liability on the basis that U.S. Mineral Products knew or should have known of the hazards posed by asbestos-containing fireproofing and failed to take adequate protective action.

Individuals who believe they have been harmed by exposure to Cafco Power-Shield should consult with an attorney experienced in asbestos litigation. Legal counsel can evaluate the specifics of a potential claim, assess exposure history, identify all potentially responsible parties—which may include not only the manufacturer but also contractors, premises owners, and other product manufacturers whose materials were used on the same job sites—and advise on applicable statutes of limitations, which vary by state and by disease diagnosis date.

Documentation that may be relevant to a claim includes employment records, union membership records, Social Security earnings statements, medical records establishing an asbestos-related diagnosis, and witness testimony or co-worker affidavits that can help establish the presence of Cafco Power-Shield at specific job sites during the relevant exposure period.
