There seems to be quite a concern about asbestos in schools.
Asbestos is a mineral that was processed and used in many different building materials.
When these materials become worn or damaged, they may start releasing asbestos fibers into the air. These airborn fibers may become lodged in the respiratory or digestive tract and cause health problems. Normally, these materials do not present a concern. They become a hazard only when they are damaged by fire or mechanical forces and have the potential to release fibers into the air. Asbestos is still used in some materials such as brake pads.
