Asbestos is a naturally occurring mineral that was once widely used in construction materials due to its durability and heat resistance. However, it was later discovered to be a health hazard due to its microscopic fibers that can cause serious lung diseases when inhaled. Asbestos can be found in many building materials, such as insulation, roofing, flooring, and even in some household items like popcorn ceilings and hairdryers.

The presence of asbestos in your building is a serious health risk that must be dealt with immediately. If you suspect that your building might contain asbestos, it's important to have a professional survey conducted to assess the situation.
