What Are Asbestos?
what are asbestos
Asbestos refers to a group of naturally occurring silicate minerals composed of thin, durable fibers that are resistant to heat, fire, and chemicals. These properties made asbestos popular in various industries until its health risks became widely recognized.
Types of Asbestos
There are six main types of asbestos minerals, divided into two categories: serpentine and amphibole. Chrysotile, the only serpentine asbestos, accounts for about 95% of asbestos used commercially. Amphibole asbestos includes amosite, crocidolite, anthophyllite, tremolite, and actinolite. All forms are hazardous to human health.
Properties and Historical Use
Asbestos fibers are remarkable for their strength, flexibility, and resistance to heat and chemical damage. These properties led to widespread use in construction materials, automotive parts, textiles, and insulation products throughout the 20th century. The material was particularly valued for its fireproofing capabilities.
The microscopic size of asbestos fibers is what makes them dangerous. When materials containing asbestos are disturbed, these tiny fibers can become airborne and easily inhaled. Once in the lungs, they can cause inflammation, scarring, and eventually lead to serious diseases like asbestosis, lung cancer, and mesothelioma.
Despite its useful properties, most countries have now banned or strictly regulated asbestos use due to health concerns. However, asbestos remains present in many older buildings and products, creating ongoing exposure risks during renovation, demolition, or natural deterioration.
Understanding what asbestos is and where it might be found is crucial for safety. While intact asbestos materials generally don't pose immediate danger, any disturbance can release harmful fibers. Professional assessment and proper abatement procedures are essential when dealing with potential asbestos-containing materials.
