From the latter years of the nineteenth century, to the early years of the twentieth, asbestos was a favored material in the construction industry. It is an excellent fire resistant material, it has high electrical resistance, and it was cheap and easy to use. Unfortunately it was not appreciated at the time that asbestos fibers posed a severe health risk to workers. The fibers can easily become airborne, and, once inhaled into the lungs they cannot be expelled on account of their size. The fibers are also sharp and can penetrate body tissues. Asbestos is therefore now best known for its health legacy for the workers, many of whom now face painful and fatal diseases. Asbestosis and mesothelioma claims have been made in civil courts around the world; many companies involved in the industry have filed for bankruptcy, and some have also faced criminal charges.
