UNUSUAL FIRE AND EXPLOSION HAZARDS: Fine metal particles produced when machined, sawed, etc., can burn. High concentration of fines 'tine particles) in the air may present an explosion hazard. Good housekeeping ana adequate ventilation are recommended. Use air-supplied or self-contained breathing apparatus if fires ire m enclosed areas. SECTION 5. REACTIVITY DATA This material is stable under most conditions. INCOMPATIBILITY: Reacts with strong acids to yield hydrogen (H7) gas. DECOMPOSITION PRODUCTS: Metallic oxides (chromates, iron oxide). See Section 9 for special precautions. HO A OOOOOI CONFTOFNTTAI GENIUM PUBLISHING MSDS H N 163 Issued 12/85 STAINLESS STEEL/COBALT BASE SECTION 6. HEALTH HAZARD INFORMATION TLV See Section 2 Stainless steel is poorly absorbed through the skin or alimentary canal, and while in the solid state it is not considered an inhalation hazard. Operations such as welding, oust generation, or fume generation will allow exposure to the elements present in tne alloy. Therefore, it is important to maintain exposure levels below the regulated levels as noted in Section 2. SHORT-TERM EXPOSURE: Symptoms include metallic taste, tightness of chest, fever, irritation to eyes, nose, throat, and skin. LONG-TERM EXPOSURE: Long-term exposure to steel fumes or dusts may cause skin sensitization (principally to cobalt and nickel) and respiratory diseases such as bronchial asthma, lung fiorosis, or pneumoconiosis. Iron oxide fume exposure may cause siderosis. FIRST AID: EYE CONTACT: Protect eyes from particulates or fume. Wash exposed eye with large amounts of water for 15 minutes. SKIN CONTACT: Protect skin from cuts or heat. Avoid prolonged contact to avoid cobalt/nickei dermatitis. INHALATION: Move to fresh air. Restore or support breathing as required. INGESTION: NA SECTION 7. SPILL, LEAK AND DISPOSAL PROCEDURES sell as scrap or landfill. Clean up spills as an inert solid. Dispose of in accordance with USHA, EPA, state,or local regulations. SECTION 8. SPECIAL PROTECTION INFORMATION RESPIRATORY PRUTEiTIUN: Use iNIOSH/MsHA-approved air-purifying oust ano fume respirator when airborne concentrations exceed the I'LVs/PELs listed m Section 2 when cutting, grinding, welding, or remeltmg. Use air-supplied or self-contained breaming apparatus f SC BA) in confined spaces. VENTILATION: Use local exhaust wnen cutting, grinding, welding, or remeltmg. Confined spaces require special attention to provide adequate ventilation. EYE PROTECTION AND PROTECTIVE CLOTHING: Eye and face protection required when welding, grin'll g, cr remeiting. Wear gloves and suitable flame-retaraant clothing. When welding, wear proper shade number. Good personal hygiene and safe work practices must be maintained. SECTION 9. SPECIAL PRECAUTIONS AND COMMENTS Always maintain exposures below the established PELs/TLVs. Always use exhaust ventilation when feasible. Arc and sparks generated when welding could be a source of ignition for combustible and flammable materials. When grinding or welding cobalt-based stainless steel, always determine the potential of exceeding TLVs by Industrial Hygiene sampling. This material is potentially contaminated with materials such as oil or other compounds. If the material is contaminated, precautions necessary to the contaminants should be considered when handling, welding, cutting, and/or heating or melting.
