SECTION 2: Hazards identification

GHS Ratings • There are no chemical hazards from these castings in solid form. • Dust or fumes generated by machining, grinding, or welding of the casting will put contaminants in the air. Since the casting is more than 90 percent iron, most of the dust of fume will be iron or iron oxide. • High production dry machining of malleable iron castings usually requires local exhaust ventilation. • •Flame cutting, arc gouging, or welding of the casting generates iron oxide fume. Inhalation of too much 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. Also see the Safety Data Sheet for welding rod being used. • Since these castings contain up to 0.1 percent chromium, airborne contaminants from machining or welding will certain traces of chromium dust or fume. If total welding fume is adequately controlled, chromium will also be controlled. • Water insoluble hexavalent chromium is classified as a human carcinogen by the ACGIH. Approximately 66% of the total chro- mium in welding fume is hexavalent, and only 5% of that is insoluble. Overexposure to hexavalent chromium is not likely if general welding fume is controlled. (The alloy and its dust does not contain insoluble hexavalent chromium.) IARC classifies hexavalent chromium as Class 1, i.e. that there is positive evidence that it can cause human lung cancer. • Other toxic metals in the alloy are present in small amounts that will not represent a hazard if total dust and fume are adequately controlled. • Grinding castings that have not been cleaned or that contain embedded silica will generate significant amounts of dust containing free silica, which can cause silicosis. Good local ventilation is frequently required to prevent over-exposure in this situation. If good ventilation is not available, use a NIOSH-approved dust respirator. IARC has classified crystalline silica as a Class 2A carcinogen, probably capable of causing lung cancer.

Potential health effects

Eyes: Metal particles in the eyes may cause irritation if not removed. Breathing: Prolonged or repeated overexposure to dust or fumes from these castings may cause the following health effects. • Iron: Siderosis, “iron pigmentation” of the lung, which can be seen in a chest x-ray, which can be seen in a chest x-ray but causes little or no disability. • Chromium (hexavalent chromium in fume from welding or arcing): Lung cancer. • Breathing excessive amounts of silica dust for a long time can cause silicosis. Silicosis causes shortness of breath, reduced capacity to do work, and weakens the defenses against other lung diseases. IARC has listed crystalline silica as Class 2A, probably can cause lung cancer. Noise: Grinding or machining castings is noisy. The OSHA limit for noise averaged over eight hours is 90 decibels (dBA). A hearing conservation program is required if exposure is over 85 dBA. If noise is at or above 90 dBA, you should wear ear muffs or ear plugs CARCINOGENICITY: INGREDIENT OSHA NTP IARC TARGET ORGAN Chromium N Y 3 Lung Hexavalent N Y 1 Lung Y = Listed as Human Carcinogen.

Elements having a listed percentage greater than zero will be present in all grades. Those having a value of “0” may not be present in certain grades. *This constituent, a toxic chemical, makes this product subject to the reporting requirements of Section 313 of Title III of the Superfund Amend- ments and Reauthorization Act of 1986 and 40 CFR Part 372. Quantity threshold amounts are 25,000 pounds for manufacturing, importing or processing and 10,000 pounds for otherwise using the listed chemical. Chemicals marked ** are reportable only if in the form of dust or fume.
