The health impact of asbestos exposure is one of the most critical aspects of the Johns Manville story. Exposure to asbestos fibers, often through inhalation, has been definitively linked to severe and often fatal health conditions. These conditions include mesothelioma, a rare and aggressive cancer that affects the lining of the lungs, abdomen, or heart; lung cancer, a leading cause of cancer deaths worldwide; and asbestosis, a chronic lung disease characterized by scarring of the lung tissue. The latency period, the time between initial exposure and the onset of disease, can range from 10 to 50 years or even longer, making early detection challenging.

The statistics on asbestos-related illnesses are stark. The American Cancer Society reports that approximately 3,000 people in the United States are diagnosed with mesothelioma each year. A significant portion of these cases is directly attributable to occupational exposure to asbestos-containing products, including those manufactured by Johns Manville. The prolonged nature of the latency period means that the consequences of past exposure continue to manifest decades later, impacting individuals, families, and healthcare systems alike. The human cost of asbestos exposure is measured not only in lives lost but also in the suffering endured by those diagnosed with these devastating diseases.

As the health hazards associated with asbestos became undeniable, the legal challenges facing Johns Manville began to escalate. Lawsuits filed by individuals suffering from asbestos-related illnesses mounted, leading to significant financial strain. The company was confronted with thousands of claims, each representing a human tragedy and a potential financial liability. The sheer volume of litigation overwhelmed the company, eventually leading to a pivotal turning point in its history: Chapter 11 bankruptcy protection.

The 1982 bankruptcy filing was a complex and multifaceted event. The bankruptcy proceedings involved reorganizing the company to address the staggering number of claims. A key element of this process was the establishment of the Manville Personal Injury Settlement Trust. The Trusts primary purpose was to provide compensation to victims of asbestos exposure, offering a pathway for financial redress. At the same time, the bankruptcy process allowed the company to restructure its operations and continue its business activities, although under significantly altered circumstances. The establishment of the Trust, while a critical step, did not erase the damage or the loss, it served as a mechanism for providing some level of justice and support to those affected by the company's past practices.

The rising awareness of asbestos-related health issues compelled regulatory bodies to take decisive action. Governmental agencies such as the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) implemented stricter guidelines and regulations aimed at reducing asbestos exposure. The primary goal was to protect workers in industrial settings and the general public from the dangers of asbestos. These regulations covered various aspects, from the permissible levels of asbestos in the air to the methods of handling and disposal of asbestos-containing materials.

Compliance with these regulatory changes required significant adaptation. Companies, including Johns Manville, were obligated to adopt safer manufacturing practices. This meant investing in research and development to identify and implement safer alternatives to asbestos. Phasing out asbestos-containing products was a gradual but necessary transition. The process demanded significant financial resources, innovative thinking, and a commitment to prioritizing safety over the status quo. These compliance measures shaped the future of the industry and laid the groundwork for a less hazardous working environment. The commitment of resources towards research and development was a key factor in this transition, helping establish the company's future direction.

Today, Johns Manville operates as a subsidiary of Berkshire Hathaway. The company has shifted its focus to producing non-asbestos building materials. Although it is no longer involved in the production of asbestos-containing products, its legacy remains inextricably linked to its historical role in the asbestos industry and the subsequent challenges it faced.
