Cafco Blaze-Shield Type H

Product Description

Cafco Blaze-Shield Type H was a spray-applied fireproofing material manufactured by United States Mineral Products Company (USMP) during a narrow production window spanning from 1969 to 1971. The product belonged to the Blaze-Shield family of cementitious fireproofing materials, a line that USMP developed and marketed extensively throughout the mid-to-late twentieth century for use in commercial and industrial construction.

Spray-applied fireproofing of this type served a critical structural purpose: when applied to steel beams, columns, decking, and other load-bearing elements, it formed an insulating layer designed to slow heat transfer and maintain structural integrity during a fire event. Type H, designated by its product suffix, represented a specific formulation within the Blaze-Shield series intended for high-temperature or otherwise demanding fireproofing applications.

Buildings constructed or renovated during the late 1960s and early 1970s — a period of rapid industrial and commercial expansion — frequently incorporated spray-applied fireproofing materials as a cost-effective and code-compliant method of protecting steel superstructures. Cafco Blaze-Shield Type H was one such product available to contractors and building owners during this era. Its production ceased in 1971, coinciding with growing regulatory scrutiny of asbestos-containing construction materials, though buildings where it was applied may have retained it in place for decades afterward.

Asbestos Content

Cafco Blaze-Shield Type H contained chrysotile asbestos as a principal component of its formulation. Chrysotile, also known as white asbestos, is a serpentine mineral fiber that was widely used in construction materials throughout the twentieth century for its heat resistance, tensile strength, and binding properties — characteristics that made it particularly attractive in fireproofing applications.

In spray-applied fireproofing products of this period, asbestos fibers were typically mixed with binding agents and other materials to create a sprayable slurry. Once applied and dried, the resulting coating encapsulated the asbestos fibers within a matrix bonded to the underlying steel. However, this binding was not permanent. Over time, through mechanical disturbance, vibration, settling, or renovation activity, the material could degrade and release respirable asbestos fibers into the surrounding air.

Litigation records document that Cafco Blaze-Shield Type H, like comparable products in the Blaze-Shield line, contained asbestos at concentrations sufficient to create significant inhalation hazards when the material was disturbed during application, maintenance, or removal. The Asbestos Hazard Emergency Response Act (AHERA), enacted in 1986, established federal standards for the identification and management of asbestos-containing materials in buildings, and spray-applied fireproofing of this type falls within the scope of materials subject to AHERA inspection and remediation requirements.

OSHA’s current permissible exposure limit (PEL) for asbestos is 0.1 fibers per cubic centimeter of air as an eight-hour time-weighted average, with an excursion limit of 1.0 f/cc averaged over a thirty-minute sampling period. These standards reflect the recognized hazard of asbestos fiber inhalation, which has been causally linked to mesothelioma, asbestosis, lung cancer, and other serious diseases.

How Workers Were Exposed

The primary occupational exposure pathway associated with Cafco Blaze-Shield Type H was inhalation of airborne asbestos fibers during the spray application process. When the product was mixed and sprayed onto structural steel surfaces, fine asbestos fibers became aerosolized and dispersed throughout the work area. Workers performing the spraying itself faced the highest direct exposures, but industrial workers and tradespeople operating in the same vicinity were also at risk due to the mobility of airborne fibers in enclosed or partially enclosed construction environments.

Litigation records document that bystander exposure was a recognized feature of spray-applied asbestos fireproofing worksites. Because the spraying process generates significant quantities of airborne particulate, other trades and workers — ironworkers, electricians, pipefitters, and general laborers — present in the same area could inhale asbestos-laden air even without directly handling the product.

Beyond the initial application phase, subsequent exposure risks arose during the building’s operational life. Maintenance workers, renovation crews, and demolition workers who later disturbed dried Blaze-Shield Type H could release previously bound fibers back into the air. OSHA’s asbestos standards specifically address disturbance of existing asbestos-containing materials as a significant exposure event, requiring engineering controls, respiratory protection, and regulated disposal procedures.

Plaintiffs alleged in litigation involving Cafco Blaze-Shield Type H that workers were not adequately warned of the asbestos content of the product or the health hazards associated with its application and disturbance. Given the narrow production window of 1969 to 1971, the universe of directly exposed workers includes those who participated in construction projects where the product was installed during those years, as well as those who performed later work in structures where the material remained in place.

Cafco Blaze-Shield Type H is classified as a Tier 2 product for legal purposes, meaning that no dedicated asbestos bankruptcy trust fund has been established to compensate individuals harmed by this specific product through United States Mineral Products Company. Compensation claims arising from exposure to this product are pursued through civil litigation rather than through a trust fund claims process.

Litigation records document that United States Mineral Products Company has been named as a defendant in asbestos personal injury and wrongful death lawsuits filed by individuals who alleged exposure to Blaze-Shield line products, including Type H. Plaintiffs alleged that USMP knew or should have known of the hazards associated with asbestos-containing fireproofing materials and failed to adequately warn workers and downstream users of those risks.

Individuals who believe they were exposed to Cafco Blaze-Shield Type H and who have subsequently been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease should consult with an attorney experienced in asbestos litigation. Because this product was manufactured and applied within a defined two-year window, establishing exposure documentation — including work history records, employment records, union records, co-worker testimony, and building inspection records — is a critical component of any legal claim.

Statutes of limitations for asbestos-related claims vary by jurisdiction and typically begin running from the date of diagnosis or the date on which the claimant knew or should have known of the connection between their illness and asbestos exposure. Prompt legal consultation is advisable to preserve all available remedies.

Eligible claimants may also investigate whether other defendants in their exposure history — including manufacturers of other asbestos-containing products used at the same worksites — have established bankruptcy trusts that accept claims, as multi-defendant claims are common in asbestos litigation involving construction products.
