III. PHYSICAL DATA
Melting Point: 2750 癋 Appearance: Metallic Gray
Odor: No Odor
IV. FIRE AND EXPLOSION HAZARD DATA
Steel Products in the solid state present No Fire or Explosion Hazard
Unusual Fire and Explosion Hazards: Temperatures above the melting point may liberate fumes of iron, nickel and zinc
oxide.
V. REACTIVITY DATA
Stable under normal conditions of use, storage, and transport. Will react with strong acid to liberate hydrogen. At
temperatures above the melting point may liberate fumes of iron, nickel and zinc oxide.
VI. HEALTH HAZARD DATA
Major Exposure Hazard
Inhalation Skin Contact Eye Contact Ingestion
Chronic Inhalation of high concentrations of Iron Oxide Fume or Dusts may lead to a Benign Pneumoconiosis
(Siderosis). Inhalation of high concentrations of Ferric Oxide may possibly enhance the risk of Lung Cancer in workers
exposed to Pulmonary Carcinogens.
The inhalation of high concentrations of freshly formed Oxide Fumes and Dusts of Manganese, Copper, Lead, and/or
Zinc in the resspirable particle size range can cause Influenza-like illness termed Metal Fume Fever. Typical symptoms last
12 to 48 hours and are characterized by metallic taste in the mouth, dryness, and irritation of the throat, followed by
weakness, muscle Pain, Fever, and Chills.
Emergency and First Aid Procedures: For overexposure to airborne fumes and particulates; remove exposed person to
fresh air. If breathing is difficult or has stopped, administer artificial respiration or oxygen as indicated. Seek Medical
Attention Promptly.
Treat Metal Fume Fever by bed rest, and administer a pain and fever reducing medication.
VII. SPILL OR LEAK PROCEDURES
Not applicable to Steel in the solid state.
Waste Disposal Method: Metals may be reclaimed. Dispose of in a Land Fill in accordance with all Local, State, and Federal
Regulations.
VIII. SPECIAL PROTECTION INFORMATION
Respiration: NOISH/MSHA ?Approved Dust and Fume Respirators should be used to avoid excessive inhalation of
particulates. Appropriate respirator selection depends on the magnitude of exposure.
Skin: Protective gloves should be worn as required for welding, burning, or handling operations.
Eye: Use Safety Glasses or Goggles as required for welding, burning, sawing, brazing, grinding, or machining operations.
Ventilation: Local exhaust ventilation should be provided when welding, burning, sawing, brazing, grinding, or machining
to prevent excessive dust or fume exposure.

Other Protective Equipment: Depending upon the conditions of use and specific work situations, additional protective
equipment and/or clothing may be required to control exposures.
IX. SPECIAL PRECAUTIONS
Handling and Storage: Operations with the potential for generating high concentrations of airbourne particulates should
be evaluated as necessary. Avoid breathing Metal Fumes and/or Dusts.
Other Comments: Medical Conditions Aggravated By Exposure: Individuals with cronic respiratory disorders (i.e. Asthma,
Chronic Bronchitis, Emphysema, etc.) may be adversely affected by any fume or airborne particulate matter exposure.
