Asbestos is a naturally occurring mineral that's been used for its insulating and fire-resistant properties for centuries. It was a widely popular material in the construction industry until the mid-1980s, when its harmful health effects were discovered. Asbestos fibers are tiny, and when inhaled, they can cause a range of respiratory issues, including lung cancer, mesothelioma, and asbestosis.

There are different types of asbestos, including:

• Chrysotile - also known as white asbestos, it's the most commonly used form of asbestos and was used in insulation products, roofing, and cement.
• Amosite - also known as brown asbestos, it was used in insulation boards, ceiling tiles, and plumbing.
• Crocidolite - also known as blue asbestos, it was used in insulation of steam engines and pipes.
