What Is Asbestos? Exposure Sources Health Risks and Who Is at Risk

Quick Answer: Asbestos is a naturally occurring mineral once prized for its heat resistance and durability, widely used in construction, shipbuilding, and manufacturing from the 1940s through the 1970s. People are exposed through occupational contact, secondary (take-home) exposure, or environmental sources, typically by inhaling or ingesting microscopic fibers. Even brief or low-level exposure can cause serious illness decades later, including asbestosis, pleural plaques, lung cancer, and mesothelioma.

Asbestos is a naturally occurring mineral made of microscopic fibers. For decades, it was prized in construction and manufacturing for its heat resistance, strength, and durability — but those same fibers, once inhaled or ingested, can cause serious and often fatal disease decades later.
Where Asbestos Was Used
From roughly the 1940s through the 1970s, asbestos was used extensively across many industries:
- Insulation — pipe, boiler, and building insulation in homes, schools, and offices
- Shipbuilding — insulation, gaskets, and fireproofing throughout Navy and merchant vessels
- Automotive parts — brake pads, clutches, and gaskets
- Construction materials — flooring, roofing, cement, and drywall joint compound
- Textiles — fireproof fabrics and protective clothing
- Industrial equipment — furnaces, ovens, and machinery requiring heat resistance
How People Are Exposed
- Occupational exposure — workers in high-risk trades and industries who handled asbestos-containing materials directly, often for years
- Secondary (take-home) exposure — family members exposed to fibers carried home on a worker’s clothing, hair, or skin; read more about secondary exposure and legal options for family members
- Environmental exposure — living near mines, factories, or naturally occurring asbestos deposits
Health Conditions Caused by Asbestos
Asbestos fibers lodge in lung tissue and other organs, where they can cause inflammation and scarring over decades. Known conditions include:
- Asbestosis — scarring of lung tissue that causes progressive breathing difficulty
- Pleural plaques — thickened areas on the lung lining, often the first visible sign of past exposure
- Pleural effusion — fluid buildup between the lung and chest wall; see our guide to pleural effusion
- Mesothelioma — an aggressive cancer of the lining of the lungs, abdomen, heart, or testicles
- Lung cancer — asbestos exposure significantly increases the risk, particularly for smokers
There is no known safe level of asbestos exposure, and symptoms of related disease often do not appear for 20 to 50 years after the initial exposure. Veterans exposed during Navy service face particular risk; see our overview of veterans’ benefits and legal options.
