What Is Asbestos?
define asbestos
Asbestos is a naturally occurring mineral fiber known for its heat resistance, strength, and insulating properties. It was widely used in construction, manufacturing, and other industries throughout the 20th century. There are six types of asbestos minerals, all composed of thin, durable fibers that can be woven or mixed into materials.
Types and Properties
The most common types of asbestos are chrysotile, amosite, and crocidolite. Chrysotile, or white asbestos, accounts for about 90-95% of asbestos used globally. Its curly fibers make it flexible and easy to incorporate into products like cement, textiles, and insulation.
Amosite (brown asbestos) and crocidolite (blue asbestos) have straight, needle-like fibers and are more hazardous than chrysotile. All forms of asbestos are resistant to heat, electricity, and chemical corrosion, which contributed to their popularity.
Health Risks
When asbestos-containing materials are disturbed, tiny fibers can become airborne and inhaled. These fibers can lodge in the lungs, causing inflammation, scarring, and eventually diseases like asbestosis, lung cancer, and mesothelioma. Due to these risks, many countries have banned or strictly regulated asbestos use.
Despite its dangers, asbestos is still present in many older buildings and products. Proper identification and handling are essential to prevent exposure.
Understanding what asbestos is and its associated risks is crucial for safety and compliance in environments where it may be present.
