Asbestos is a hazardous substance that can cause serious health problems when inhaled. It was widely used in building materials in the past, but has since been banned in many countries due to the serious risks it poses to human health.

Asbestos can cause diseases such as lung cancer, mesothelioma, and asbestosis, among others. These diseases can take years to develop and can be fatal.

Asbestos was used in many different building materials, including insulation, roofing materials, floor tiles, and cement. Many buildings still contain asbestos, and when these materials are disturbed or damaged, the asbestos can become airborne and pose a serious risk to anyone who inhales it.
