Cafco Blaze-Shield Type M

Product Description

Cafco Blaze-Shield Type M was a spray-applied fireproofing material manufactured by United States Mineral Products Company (USMP), a New Jersey-based manufacturer that operated under the trade name “Cafco.” The product belonged to the broader Blaze-Shield product line, which represented one of the most widely used families of spray-applied fireproofing materials in mid-twentieth century American construction and industrial applications.

Spray-applied fireproofing of this type was engineered to protect structural steel, concrete decking, and other building components from heat-induced failure during fire events. Type M was marketed for use in demanding environments where enhanced fire resistance ratings were required, making it a common specification in industrial facilities, manufacturing plants, power generation stations, and heavy commercial construction projects. The product was applied wet and adhered directly to structural surfaces, where it cured into a lightweight, fibrous insulating layer.

USMP positioned the Blaze-Shield line as a technically superior alternative to field-mixed fireproofing compounds, offering contractors a pre-formulated product that could be applied efficiently using conventional spray equipment. As a result, the material was distributed widely across the construction supply chain and appeared on job sites throughout the United States during the decades of peak asbestos use in building materials.

In addition to its fireproofing applications, Cafco Blaze-Shield Type M and related products from the same manufacturer were also used in pipe insulation contexts within industrial settings, where thermal and fire-resistive properties were both required. This dual-application profile broadened the population of workers who came into contact with the material during installation, maintenance, and renovation work.

Asbestos Content

Cafco Blaze-Shield Type M contained asbestos as a functional component of its formulation. Asbestos fibers were incorporated into spray-applied fireproofing products by manufacturers during this era because the mineral offered a combination of properties that were difficult to replicate with alternative materials: high tensile strength within a lightweight matrix, excellent thermal stability, resistance to chemical degradation, and the ability to bind other ingredients into a cohesive, adherent coating.

Litigation records document that plaintiffs alleged the product contained asbestos as a primary or significant constituent of its composition. The specific fiber type or precise percentage concentration in Type M’s formulation is not independently established in publicly available regulatory filings reviewed for this article, and product specifications varied across manufacturing periods. However, litigation records document that asbestos content in the Blaze-Shield product family was the subject of substantial legal dispute, with plaintiffs alleging that the material released respirable asbestos fibers during normal application and disturbance activities.

Regulatory actions taken under the National Emission Standards for Hazardous Air Pollutants (NESHAP) and the Asbestos Hazard Emergency Response Act (AHERA) established frameworks for identifying and managing spray-applied asbestos-containing fireproofing materials in existing structures, and materials of this type and era fall within the categories addressed by those regulatory programs. When encountered in existing buildings or industrial facilities today, spray-applied fireproofing from this period is presumed to be asbestos-containing under applicable EPA and OSHA guidance until tested and confirmed otherwise.

How Workers Were Exposed

Exposure to asbestos from Cafco Blaze-Shield Type M occurred across multiple stages of a product’s life cycle, from initial installation through subsequent maintenance and renovation activities.

Application workers faced the most direct and concentrated exposures. Spray-applied fireproofing was mixed and applied using equipment that aerosolized the wet compound, generating significant airborne fiber release in enclosed or partially enclosed work areas. Workers operating spray equipment, as well as those working nearby on the same floor or in adjacent trades, inhaled fibers without the benefit of meaningful respiratory protection during the decades when occupational asbestos standards were either absent or inadequate.

Ironworkers, structural steel workers, and construction laborers were also present during application phases and worked in the contaminated environment created by overspray. Litigation records document that plaintiffs alleged exposures occurring simply by working in proximity to active spray operations, as fibrous material drifted beyond the immediate application zone.

Pipefitters and industrial insulation workers encountered the material in settings where Blaze-Shield Type M was used for pipe insulation applications. These workers cut, shaped, and fitted insulating materials, activities that generate dry fiber release from asbestos-containing products. Maintenance and repair activities on previously insulated pipe systems were particularly hazardous because aged or damaged asbestos-containing insulation becomes more friable over time, releasing fibers with minimal mechanical disturbance.

Demolition and renovation workers faced exposures in a second wave decades after original installation. As industrial facilities and commercial buildings underwent modernization, asbestos-containing fireproofing and insulation materials were disturbed, removed, or damaged. Workers performing these tasks—often without awareness that asbestos-containing materials were present—were exposed to accumulated fiber release from materials that had dried, degraded, and become highly friable.

General industrial workers employed at facilities where the product was installed also appear in litigation records as plaintiffs, reflecting the reality that bystander exposure in industrial environments was not limited to tradespeople actively working with the material. OSHA’s permissible exposure limits for asbestos, established and progressively tightened through regulations promulgated in the 1970s through the 1990s, were not in place to protect workers during the earlier decades when exposure was most widespread.

The latency period for asbestos-related diseases—commonly ranging from 20 to 50 years between exposure and clinical diagnosis—means that individuals exposed to Cafco Blaze-Shield Type M during its years of peak use may be receiving diagnoses of mesothelioma, asbestosis, lung cancer, or related conditions today.

Documented Trust Fund / Legal Options

United States Mineral Products Company does not have an established asbestos bankruptcy trust fund of record as of the time of this publication. Accordingly, legal claims related to Cafco Blaze-Shield Type M and other USMP products have proceeded through the civil litigation system rather than through a structured trust fund claims process.

Litigation records document that USMP faced asbestos-related personal injury lawsuits brought by workers and their families alleging harm from exposure to Blaze-Shield products. Plaintiffs alleged that USMP knew or should have known of the hazards associated with asbestos-containing products and failed to provide adequate warnings to workers and end users.

Individuals diagnosed with mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease following exposure to Cafco Blaze-Shield Type M should consult with an attorney experienced in asbestos litigation to evaluate their options. Potential legal pathways may include:

  • Direct litigation against responsible parties in the product’s chain of commerce, including manufacturers, distributors, and premises owners
  • Premises liability claims against industrial facility owners who specified or permitted the use of asbestos-containing fireproofing on their properties
  • Claims against other trust funds for exposure to additional asbestos-containing products used concurrently on the same job sites, as asbestos-disease claimants often have documented exposure to multiple products from multiple manufacturers

State statutes of limitations govern the time within which claims must be filed, and deadlines vary by jurisdiction and by the date of diagnosis or discovery of the disease. Legal consultation should be sought promptly following any diagnosis of an asbestos-related condition.
