Solid metallic products are <br />classified as "articles" and are not hazardous material under the definitions of OSHA Hazard Communication Standard (29 CFR 1910.1200). <br />Stainless steel products in their solid state present no inhalation, ingestion or contact health hazard. However, inhaling dusts fumes or musts which may be <br />generated during certain manufacturing procedures such as burning, melting, welding, sawing, brazing, grinding and machining may be hazardous to your <br />health. Dusts may also be irritating to the unprotected skid and eyes. <br />Short Term exposure to fumes/dust generated from stainless steel use and processing may produce irritation of the eyes and respiratory system. Inhalation <br />of high concentrations of freshly formed oxide fumes of iron, manganese and copper may cause metal fume fever, characterized by a metallic taste in the <br />mouth, dryness and irritation of the throat and influenza4ike symptoms. <br />Chronic inhalation of high concentrations of iron oxide fumes or dust may lead to a benign pneumoconiosis (siderosis). Inhalation of high concentrations of <br />ferric oxide may possibly have a synergistic effect and increase the risk of lung cancer development in workers exposed to pulmonary carcinogens. <br />Chromium and nickel and their compounds are listed in NTP's 70 Annual Report on Carcinogens. Exposure to dust and fumes can cause sensitization <br />dermatitis, inflammation and/or ulceration of upper respiratory tract, and cancer of nasal passages and lungs. <br />NTP classifies nickel metal and certain nickel compounds as "reasonably anticipated to be carcinogens:' IARC classifies nickel metal as a possible human <br />carcinogen (Group 2B) and certain nickel compounds as known human carcinogens (Group 1). <br />NTP reports that there is inadequate evidence for the carcinogenicity of chromium metal and most trivalent chromium (CrIII) compounds in humans and <br />experimental animals. However, NTP classifies certain hexavalent chromium compounds as "known to be carcinogens." Similarly, IARC indicates that <br />chromium metal and trivalent chromium compounds are not classifiable as human carcinogens (Group 3), but that certain hexavalent chromium compounds <br />are known carcinogens (Group 1). Since the hexavalent form of chromium may be produced during welding, heat -treating and alkaline descaling processes, <br />an industrial hygiene evaluation of such process should be conducted to determine if exposure to hexavalent chromium is present. <br />Section 3 Composition/Information on In `redients <br />Component <br />CAS Number <br />EC Number <br />% weighti <br />Iron <br />[Iron oxide] <br />(Fe) <br />7439-89-6 <br />231-096-4 <br />60 - 88 <br />Alloying Elements <br />Chromium3 <br />(Cr) <br />744047-3 <br />231-157-5 <br />10-30 <br />(Metal) <br />Nickel3 <br />(Ni) <br />7440-02-0 <br />231-1114 <br />O-46 <br />Metal <br />Manganese <br />(Mn) <br />7439-96-5 <br />231-1054 <br />0-15 <br />elemental & inor anic c ds <br />Molybdenum <br />(Mo) <br />7439-98-7 <br />231-107-2 <br /><8 <br />Copper3 <br />(Cu) <br />7440-50-8 <br />231-159-6 <br />< 6 <br />Titanium3 <br />(Ti) <br />13463-67-7 <br />231-142-3 <br />< 6 <br />[metal & dioxide] <br />Carbon <br />(C) <br />744044-0 <br />231-153-3 <br />< 2 <br />Aluminum 3 <br />(Al) <br />7429-90-5 <br />231-072-3 <br />< 2 <br />Rev.
