Carbon and Alloy Steels 4. FIRST AID ME SURES Eye Contact - in case of overexposure to dusts or fumes, immediately flush eyes with plenty of water for at least 15 minutes occasionally lifting the eye tide. Get medical attention If irritation persists. Thermal burns should be treated as medical emergencies. medn Contact - in ical attention if asetof develops oepeto rs s ss If thermal bum occurs, flu h area with dustor particulates, wash with soap and eold water tand get irriimmediate medical attention. sts or fumes, remove to fresh air_ Get imrnedlatB medical attention Inhalation - In case of overexposure to du if symptoms described In this SDS develop. Ingestion - Not considered an ingestion hazard. However, if excessive amounts of dust or particulates are swallowed. treat symptomatically and supportively. Get medical attention. with Notes to Physician - Inhalation of metal fume or metal oxides may p oducle ce anacctcramps, febrile bri erstate, b e cough, chills, weakness, and general malaise, nausea, vomiting, musleukocytosis. Treatment is symptomatic, and condition is self limited in 24-48 hours. Chronic exposure to dusts may result in pneumoconlosis of mixed type. S. FIRE FIGHTING MEASURES Flash Point (Method) - Not applicable Flammable Limits (% volume In air) - Not applicable Auto ignition Temperature - Not applicable, or sand. For steel dust use or dry sand, water, Extinguishing Media - For molten metal, use dry powder foam, argon or nitrogen.rbon ox d Special t=ire Fighting Procedures - Do not use water on molten metal. Do not use Cro ed Dos five (CO2). Firefighters should not enter confined spaces without wearing NIOSH/MeS HA app P pressure breathing apparatus (SCSA) with full face mask and full protective equip Unusual Fire or Explosion Hazards - Steel products do not present fire or explosion hazards under normal conditions. Any non -oxidized fine metal particles/ dust generated by grinding, sawing, abrasive blasting, or Individual customer processes may produce materials that the customer should test for combustibility and other hazards in accordance with applicable regulations. High concentrations of combustible metallic fines in the air may present an explosion hazard. 6. ACCIDENTAL RELEASE MEASURES Precautions If Material Is Spilled or Released -Emergency response Is unlik Ay ate pless in the form of recautions outlined combustible dust. Avoid inhalation, eye, or skin contact of dusts by using appropriate pre and placed into in this SDS (see section 8). Fine turnings and small chips should be swept appropriate disposable containers. Keep fine dust or powder away from sources of Ignition. Scrap should be . rials from entering drains, sewers, or waterways- Specific standards reclaimed for recyclingPrevent mate and regulations may be applicable to materials genera tetl by individual customer processes. As appropriate, these standards and regulations should be consulted for applicaberate combustible dust that may require Fire and Explosion Hazards - Some customer processes may gen specific precautions when cleaning spills or releases of dust. Environmental Precautions - Some grades of steel may contain reportable quantities of alloying elements. See Section 15 for additional information. Waste Disposal Methods - Dispose of used or unused product in accordance with applicable Federal, State, and Local regulations. Please recycle. 7 HAN LING AND STORAGE Storage Temperatures - Stable under normal temperatures and pressures. Precautions to be Taken in Handling and Storing - Store away from strong oxidizers. Dusts and/or powders, alone, or combined with process specific fluids, may form explosive mixtures with air. Applicable Federal, state and local laws and regulations may require testing dust generated from processing of steel Revision Date: 1212=014 Page 4 of 8
