For years fibreglass dust has been considered to be a nuisance (irritation) dust which does not cause disease. Now studies show that fibreglass dust can be dangerous, maybe as dangerous as asbestos dust. The implantation of fibreglass into the lining of the lungs of animals has caused cancer in the same way that asbestos does. Scientists now believe that asbestos causes cancer because of the physical shape of the fibre and not because of its chemical make up, This belief raises the concern that all fibrous materials could cause cancer.
