General dilution ventilation should be provided as necessary to keep airborne dust and fibers below the applicable exposure limits and guidelines. The need for ventilation systems should be evaluated by a professional industrial hygienist, while the design of specific ventilation systems should be conducted by a professional engineer. Exposed skin areas should be washed with soap and warm water after handling or working with fiber glass. This is a stable material. This product is not reactive.
Crystalline silica is a hazard by inhalation.
Prolonged, excessive inhalation of crystalline silica can cause silicosis, a non-cancerous lung disease that can result in pulmonary failure. Heart enlargement has been also observed with silicosis, and can lead to heart failure. Several studies had been conducted to determine the risk of cancer to workers exposed to dusts that contained crystalline silica. These studies did not control for other agents to which the workers may have been exposed, so the cause of the cancers resulting in excess deaths in the study could not be precisely determined. Further studies are being conducted to determine the risk of cancer when working with crystalline silica products.
