What are the two types of asbestos that are most commonly used?

The two types of asbestos that are most commonly used are chrysotile and amphibole asbestos. Chrysotile, often referred to as "white asbestos," is the most prevalent form, comprising about 95% of the asbestos found in industrial applications. It is commonly used in roofing materials, insulation, and various other products due to its heat resistance and flexibility.

Amphibole asbestos includes several minerals such as amosite (brown asbestos) and crocidolite (blue asbestos). While chrysotile is more widely used, amphibole types are also significant in past industrial uses and have distinct properties that make them relevant in various contexts. For instance, amosite was often utilized in insulation materials, while crocidolite has historical applications in other industrial contexts.

Understanding these two categories is important for recognizing the health risks associated with asbestos exposure, as both types have different levels of toxicity and health implications.
