Atlas Turner Newalls 85% Magnesia Pipe Insulation

Product Description

Atlas Turner Newalls 85% Magnesia was a thermal pipe insulation product manufactured and distributed during the postwar industrial expansion era, remaining in production from approximately 1950 through 1963. The product belonged to a widely used category of high-temperature insulation materials formulated around magnesium carbonate compounds, commonly referred to in the trade as “85% magnesia” insulation — a designation reflecting the approximate composition of magnesium carbonate that formed the product’s primary heat-resistant base.

85% magnesia insulation products were considered industry-standard solutions for insulating high-temperature piping systems in industrial facilities, power generation plants, refineries, shipyards, and manufacturing installations throughout the mid-twentieth century. These materials were engineered to withstand sustained operating temperatures and were applied to steam lines, process piping, boiler systems, and distribution networks wherever thermal efficiency and heat containment were priorities.

Atlas Turner Newalls marketed this insulation to industrial buyers during a period when demand for reliable, cost-effective pipe insulation was significant. The product was fabricated in sectional block and pipe-covering forms that could be cut, fitted, and secured around pipe runs of varying diameters, making it adaptable to the complex piping configurations typical of large industrial facilities.

Asbestos Content

Atlas Turner Newalls 85% Magnesia pipe insulation contained chrysotile asbestos as a reinforcing component within its magnesium carbonate matrix. Chrysotile, the most commercially prevalent form of asbestos during the twentieth century, was incorporated into magnesia insulation products across the industry because of its fibrous, heat-resistant properties that complemented the thermal performance of the magnesium compound base.

In 85% magnesia insulations, chrysotile fibers served a structural function — binding the relatively brittle magnesium carbonate matrix together, improving tensile strength, and enabling the material to be formed into the pipe sections, block shapes, and finishing cements necessary for practical installation. Without fibrous reinforcement, magnesia-based insulations would have been too fragile for the mechanical demands of installation and long-term service on industrial piping systems.

Chrysotile asbestos is classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and is regulated by the U.S. Occupational Safety and Health Administration (OSHA) under strict permissible exposure limits codified at 29 CFR 1910.1001 for general industry and 29 CFR 1926.1101 for construction. No safe level of occupational asbestos exposure has been established by regulatory or public health authorities.

The Asbestos Hazard Emergency Response Act (AHERA) and subsequent EPA regulatory frameworks have classified chrysotile, along with all other commercially used asbestos fiber types, as hazardous materials subject to regulated handling, removal, and disposal procedures.

How Workers Were Exposed

Industrial workers who handled, installed, maintained, or removed Atlas Turner Newalls 85% Magnesia pipe insulation faced potential exposure to airborne chrysotile asbestos fibers during ordinary work activities associated with this product. Litigation records document that plaintiffs alleged significant fiber release occurred throughout the product’s useful life — during initial installation as well as during the decades of maintenance, repair, and eventual removal that followed.

Installation work was among the most exposure-intensive phases. Workers cutting magnesia pipe sections to length with hand saws or power tools, shaping and fitting insulation segments to complex pipe configurations, and applying finishing cements or canvas jacketing generated airborne dust containing chrysotile fibers. These tasks were performed in enclosed mechanical rooms, pipe chases, and utility corridors where ventilation was frequently limited.

Maintenance and repair activities presented ongoing exposure risks throughout the product’s service life and beyond. Industrial workers who disturbed existing magnesia insulation to access valves, flanges, or piping for repair work — and who subsequently replaced or re-secured insulation material — released fibers from material that had been in place for years and had often become friable and more easily disturbed with age.

Removal and abatement work created documented exposure concerns as facilities modernized their insulation systems or replaced aged pipe coverings. Plaintiffs alleged that workers tasked with stripping old magnesia insulation from pipe systems — cutting, breaking, and disposing of the material — encountered some of the highest fiber concentrations associated with this product category.

Litigation records document that industrial workers generally, including pipefitters, insulators, millwrights, boilermakers, and general plant maintenance personnel, were among those who alleged occupational exposure to Atlas Turner Newalls 85% Magnesia during the years the product was in active use and during subsequent disturbance activities. Because large industrial facilities could contain extensive runs of this insulation applied during the 1950s and early 1960s, workers who spent careers in such facilities might have accumulated repeated exposure events over many years.

Bystander exposure was also alleged in litigation records, with plaintiffs describing how fiber-laden dust generated during insulation work could affect other tradespeople or general laborers working in adjacent areas of the same facility.

Diseases associated with occupational chrysotile asbestos exposure and documented in asbestos litigation generally include mesothelioma, lung cancer, asbestosis, and other asbestos-related pulmonary conditions. Latency periods for asbestos-related diseases — the interval between initial exposure and clinical diagnosis — typically span several decades, meaning workers exposed to this product during its production years of 1950 through 1963 may have received diagnoses well into the late twentieth or early twenty-first century.

Atlas Turner Newalls 85% Magnesia is classified as a Tier 2 litigated product. No dedicated asbestos bankruptcy trust fund has been established specifically for claims arising from this product. Individuals seeking legal remedy for asbestos-related diseases connected to exposure to this insulation must pursue compensation through the civil litigation system rather than through a trust fund claims process.

Litigation records document that plaintiffs have brought claims alleging injury from exposure to Atlas Turner Newalls 85% Magnesia pipe insulation, asserting causes of action that have included product liability, negligence, and failure to warn. Plaintiffs alleged that manufacturers and distributors of asbestos-containing insulation products had knowledge of the hazards associated with asbestos fiber inhalation and failed to adequately warn workers of those risks or to provide protective measures that could have reduced exposure.

Individuals who may have legal claims include those who:

  • Worked directly with Atlas Turner Newalls 85% Magnesia in installation, maintenance, or removal roles
  • Were employed at facilities where this product was present and experienced bystander exposure
  • Have received a diagnosis of mesothelioma, lung cancer, asbestosis, or another asbestos-related condition with a documented history of industrial asbestos exposure

Because no trust fund filing option exists for this product, pursuing civil litigation typically requires working with an attorney experienced in asbestos personal injury law. Statutes of limitations for asbestos claims vary by jurisdiction and generally begin running from the date of diagnosis rather than the date of exposure, though the specific rules differ by state.

Anyone with a potential claim involving this product is encouraged to consult a qualified asbestos litigation attorney to evaluate their legal options, identify all potentially liable parties, and understand the applicable deadlines in their jurisdiction.
