Principle Routes of Exposure

Inhalation (dry form only), ingestion and dermal May cause skin and eye irritation, Lung effects including cancer, silicosis Silica, Crystalline (Quartz) A single exposure will not result in serious adverse health effects. Respirable crystalline silica (quartz) can cause silicosis, a fibrosis (scarring) of the lungs. Silicosis may be progressive; it may lead to disability and death. Crystalline silica (quartz) inhaled from occupational sources is classified as carcinogenic to humans. There are some studies that show excess numbers of cases of scleroderma and other connective tissue disorders in workers exposed to respirable crystalline silica. Silicosis increases the risk of tuberculosis. Some studies that show an increased incidence of chronic kidney disease and end-stage renal disease in workers exposed to respirable crystalline silica. Zirconium or Zirconium Compounds Skin, lung granulomas; in animals: irritation skin, mucous membrane; X-ray evidence of retention in lungs. Tin or Tin Compounds Chronic exposure to Tin Oxide fumes or dust may result in Stannosis, a form of Pneumoconiosis.
