Asbestos refers to a group of naturally occurring silicate minerals that were widely used in the construction industry before the 1990s. Asbestos is valued for its heat-resistant, insulating, and fire-retardant properties, and it can be found in various building materials, such as:

• Fireproofing and acoustic insulation
• Pipe and boiler insulation
• Ceiling tiles and floor tiles
• Roofing materials and shingles
• Textured coatings and paints
• Adhesives and sealants

However, exposure to asbestos fibers can cause serious health problems, including lung cancer, mesothelioma, and asbestosis. Asbestos is now banned in many countries, but it still exists in many buildings and structures, especially older ones.
