Asbestospray Spray Fireproofing by Johns-Manville

Product Description

Asbestospray was a spray-applied fireproofing product manufactured by Johns-Manville Corporation, one of the largest and most historically significant producers of asbestos-containing materials in the United States. The product was designed to be applied directly to structural steel beams, columns, floor decking, and other building components where fire resistance was required by building codes or engineering specifications.

Spray-applied fireproofing became a standard feature of mid-twentieth century commercial and industrial construction. As buildings grew taller and more complex, architects and structural engineers demanded efficient methods of protecting steel frameworks from the rapid temperature increases that can cause structural failure during a fire. Asbestospray answered that demand with a product that could be quickly and evenly applied across large surface areas using pressurized spray equipment. The product adhered to steel and other substrates, forming a textured, fibrous coating intended to insulate the underlying structure against heat.

Johns-Manville marketed Asbestospray to contractors, building owners, and specifiers throughout the construction industry. The product was used in office towers, hospitals, schools, industrial facilities, warehouses, and public buildings across the United States. Because fire codes in many jurisdictions required passive fireproofing on exposed structural steel, demand for spray-applied products like Asbestospray remained strong throughout the period of the product’s commercial availability.

Asbestos Content

Asbestospray contained asbestos as a primary functional ingredient. Asbestos fibers were integral to the product’s performance characteristics: the mineral’s heat resistance, tensile strength, and fibrous structure made it effective at slowing heat transfer to protected substrates. The product belonged to a class of spray-applied materials that relied on asbestos content to achieve the fire-resistance ratings required by building and life-safety codes.

Johns-Manville sourced asbestos from its own mining operations as well as external suppliers, giving the company significant vertical integration in the production of asbestos-containing materials. The asbestos used in spray fireproofing products of this era was typically chrysotile (white asbestos), though other fiber types were used in various formulations across the industry.

The friable nature of spray-applied asbestos fireproofing has long been recognized as a significant hazard. Because the applied coating is soft and loosely bound compared to other asbestos-containing materials, it can release fibers into the air through routine disturbance, vibration, air movement, or physical contact. The United States Environmental Protection Agency’s Asbestos Hazard Emergency Response Act (AHERA) specifically addresses spray-applied surfacing materials as a category of asbestos-containing material requiring identification, assessment, and management in school buildings. Regulatory frameworks developed under AHERA and related OSHA standards reflect decades of scientific and medical documentation linking asbestos fiber inhalation to serious pulmonary diseases.

How Workers Were Exposed

Workers in a range of trades and industrial settings faced exposure to asbestos fibers through contact with Asbestospray during application, finishing, and subsequent disturbance of the material.

Application workers faced some of the most direct and concentrated exposures. Spray fireproofing was applied using equipment that aerosolized the product mixture, generating visible clouds of fiber-laden material. Workers operating spray equipment or working in proximity to active spraying operated in environments where airborne asbestos fiber concentrations could reach significant levels. Respiratory protection was frequently inadequate or entirely absent during the decades when workplace asbestos standards were either nonexistent or poorly enforced.

Construction trades workers who followed fireproofing crews onto job sites encountered residual asbestos dust and overspray deposited on work surfaces, scaffolding, tools, and building components. Ironworkers, electricians, plumbers, pipefitters, sheet metal workers, and other trades who worked around or above sprayed steel could disturb settled asbestos-containing material during the course of their own work.

Maintenance and renovation workers faced ongoing exposure throughout the operational life of buildings containing Asbestospray. Drilling, cutting, scraping, or otherwise disturbing the friable coating during building modifications or repairs could release asbestos fibers in concentrations well above background levels. Industrial workers in facilities where Asbestospray had been applied to structural components could encounter disturbed material as buildings aged, settled, or underwent routine maintenance.

General industrial workers in facilities where Asbestospray-coated structures were present were subject to secondary or bystander exposure, particularly in environments where the coating had been damaged, had deteriorated with age, or was subject to vibration and air movement from industrial equipment.

OSHA’s asbestos standards, developed and revised over several decades, establish permissible exposure limits and required control measures that reflect the recognized dangers of asbestos fiber inhalation. Diseases associated with asbestos exposure include mesothelioma, asbestosis, lung cancer, and other serious conditions, many of which have long latency periods between initial exposure and clinical diagnosis.

Johns-Manville filed for bankruptcy in 1982, a filing driven in substantial part by the volume of asbestos-related personal injury claims the company faced. The reorganization process resulted in the establishment of the Manville Personal Injury Settlement Trust, which was created to compensate individuals harmed by exposure to Johns-Manville asbestos-containing products, including Asbestospray spray fireproofing.

The Manville Personal Injury Settlement Trust is one of the oldest and largest asbestos bankruptcy trusts in the United States. The trust operates under procedures designed to evaluate and compensate eligible claimants based on documented exposure to covered products and a qualifying diagnosis of an asbestos-related disease.

Eligible claim categories typically recognized by the trust include:

  • Mesothelioma — malignant mesothelioma of the pleura, peritoneum, or pericardium
  • Lung cancer — primary lung cancer with documented asbestos exposure history
  • Asbestosis — pulmonary fibrosis attributable to asbestos inhalation, documented by medical and occupational history
  • Other asbestos-related conditions — additional disease categories as defined under the trust’s claims resolution procedures

To file a claim with the Manville Personal Injury Settlement Trust, claimants or their legal representatives must document exposure to a covered Johns-Manville product such as Asbestospray, provide qualifying medical evidence of an asbestos-related diagnosis, and submit materials consistent with the trust’s current claims resolution procedures.

Individuals who worked as industrial workers in facilities where Asbestospray was applied, or who otherwise encountered this product during its application or through subsequent disturbance of applied coatings, may have a basis for filing a trust claim. Because asbestos-related diseases frequently present decades after the initial exposure, many individuals are only now receiving diagnoses connected to occupational exposures that occurred during the peak period of Asbestospray use.

Persons who believe they may have been exposed to Asbestospray or other Johns-Manville asbestos-containing products should consult with an attorney experienced in asbestos litigation and trust fund claims to evaluate their eligibility and preserve any applicable filing deadlines.
