CHROMIUM-BASED STEEL CASTINGS

Potential health effects

EYES: Grinding or machining of castings may generate flying metal particles that may cause eye irritation. SKIN: Dermatitis or irritation is possible from skin contact with nickel, carbon, silicon or chromium. INGESTION: Ingestion of particulate can occur during activities such as eating, drinking and smoking, etc. Not normally applicable. INHALATION: Prolonged or repeated exposure to dust or fumes from these castings may cause the following health effects: Carbon: Respiratory irritation Chromium, hexavalent: Lung and nasal cancer Cobalt: Respiratory sensitization, asthma, scarring of the lungs and damage to the heart muscle Copper: Nose and throat irritation, metal fume fever, Iron: Overexposure to iron oxide fume over a long time can cause siderosis, sometimes called “iron pigmentation” of the lung. It can be seen on a chest x-ray but causes little or no disability. Manganese: Ceniral nervous system impairment Molybdenum: Lower respiratory irritation Nickel: Lung and nasal cancer Silicon: Nose irritation Tungsten: Irritation of the respiratory tract Vanadium: Respiratory irritation Note: Prolonged breathing of excessive amounts of silica dust, which may be on or embedded in the surface of castings can cause silicosis or other health effects including tung cancer
