The Hidden History of Asbestos in America

Asbestos, once hailed as a “miracle mineral,” has a complex and troubling history in the United States. From its early industrial adoption to its link with deadly diseases, this carcinogenic material has left an indelible mark on public health and workplace safety. This blog unpacks the scientifically proven facts behind asbestos use in America, its devastating health consequences, and the regulatory battles that continue today.

The Early Days: Asbestos in Industrial America

Asbestos, a naturally occurring silicate mineral, was prized for its heat resistance, durability, and insulating properties. Historical records show its use in the U.S. dates back to the late 1800s, when industries began integrating it into textiles, insulation, and construction materials.

• 1890s–1930s: Asbestos became a staple in manufacturing, particularly for steam engines, boilers, and electrical systems. The Johns-Manville Corporation, founded in 1858, emerged as a leading producer of asbestos-containing products.
• World War II: Demand skyrocketed as asbestos was used extensively in U.S. Navy ships, military vehicles, and aircraft. Over 4.5 million American workers were exposed during this period, including shipyard crews and construction teams.

Despite early warnings—such as a 1906 report by British physician Dr. H. Montague Murray linking asbestos to lung damage—U.S. industries prioritized profit over safety.

The Health Crisis Emerges: Scientific Revelations

By the mid-20th century, medical research began confirming the lethal risks of asbestos exposure. Key findings include:

• 1964 Landmark Study: Dr. Irving Selikoff’s research revealed that 33% of asbestos factory workers developed lung abnormalities. His work exposed the disproportionate impact on insulation installers, shipyard workers, and miners.
• Diseases Linked to Asbestos:
  • Mesothelioma: A rare cancer affecting the lining of the lungs or abdomen, almost exclusively caused by asbestos. The CDC reports approximately 3,000 mesothelioma deaths annually in the U.S.
  • Asbestosis: A chronic lung disease marked by scarring, leading to respiratory failure.
  • Lung Cancer: The National Institute for Occupational Safety and Health (NIOSH) states asbestos exposure increases lung cancer risk by 400%.

Latency periods of 20–50 years meant many victims didn’t show symptoms until decades after exposure.

Regulatory Response: A Slow Path to Accountability

Public outcry and scientific evidence forced policymakers to act, albeit slowly:

• 1971: The Occupational Safety and Health Administration (OSHA) set the first permissible exposure limit (PEL) for asbestos: 12 fibers per cubic centimeter of air.
• 1973: The EPA banned asbestos in spray-applied insulation under the Clean Air Act.
• 1989: The EPA attempted a full ban under the Toxic Substances Control Act (TSCA), but a 1991 court ruling overturned it, allowing limited use in products like roofing materials and gaskets.
• 2020: The EPA’s Final Risk Evaluation for Asbestos confirmed ongoing risks, leading to proposed restrictions on chrysotile asbestos imports.

Despite regulations, loopholes persist. The U.S. imported 114 metric tons of asbestos in 2022, primarily for the chlor-alkali industry.

Asbestos in Modern America: Lingering Threats

Though banned in over 60 countries, asbestos remains legal in the U.S. under limited circumstances. Key concerns include:

• Legacy Infrastructure: An estimated 30 million homes and buildings constructed before 1980 contain asbestos in insulation, tiles, or pipe cement. Renovations or disasters (e.g., hurricanes) can disturb these materials.
• Occupational Exposure: The CDC identifies 20,000 annual U.S. deaths from asbestos-related diseases, with firefighters, construction workers, and demolition crews at highest risk.
• Consumer Products: Older appliances, automotive parts, and imported goods may still contain asbestos.

Legal Battles and Corporate Accountability

Litigation has shaped asbestos history:

• 1973 Landmark Case: Clarence Borel won the first successful mesothelioma lawsuit against asbestos manufacturers.
• Asbestos Trust Funds: Over $30 billion has been allocated to compensate victims via trusts established by bankrupt companies like Johns-Manville.
• 2023 Developments: The Furthering Asbestos Claim Transparency (FACT) Act continues to spark debate over victim compensation transparency.

Protecting Yourself: What You Need to Know

• Testing: Hire EPA-certified professionals to inspect homes built before 1980.
• Avoid DIY Removal: Disturbing asbestos-containing materials releases hazardous fibers.
• Stay Informed: Monitor the EPA’s ongoing efforts to regulate chrysotile asbestos under the 2016 TSCA amendments.
