III.   Overview:



       There are no chemical hazards from these castings in solid form at room temperature.

       Machining, grinding, welding and flame or Air-Arc cutting of castings can generate

       dust or fume. Most of this will be iron or iron oxide and overexposure to iron oxide

       can cause siderosis or iron pigmentation of the lungs. Little or no disability results

       from siderosis.



       This same dust fume may also contain chromium and nickel. If the total dust fume

       from the process is kept below TLV then the individual components will be

       adequately controlled.



       Some forms of nickel have been found to cause cancer in animals. The potential for

       ordinary forms of nickel or its oxides to cause cancer in humans is very weak if it

       exists at all.



IV.    Physical Data:



       Odorless silver gray solid with a S.G. of about 7.8. Other properties as BP, VP and

       water solubility are not applicable.





V.     Fire Explosion Data:



       Low alloy steel castings will not burn or explode.

                                                            Containing the letters C, H or K.



                                                                                            Page 2



VI.     Health Hazard Data:



        Eyes: Metal particles in the eyes may cause irritation if not removed. Particles

              should be removed by a trained person.



        Skin Contact: No hazards known.



        Breathing :      Prolonged or repeated exposure to iron oxide fume may cause

                         siderosis. Maintain adequate ventilation when welding on or thermally

                         cutting castings.



        Ingestion        Not applicable



VII.    Reactive Data:



        Low Alloy steel castings are chemically stable. Hazardous polymerization will not

        occur. Chromium metal dust may burn or explode on contact with ammonium

        nitrate.



VIII.   Spill and Leak procedure:



        Dust collected from machining, welding or thermal cutting may be classified as

        "Hazardous Waste". Also, castings can be recycled. Consult local authorities about

        disposition of these items.



IX.     Protective Equipment:



        Respiratory:     Wear a NIOSH approved respirator for dust or fume if concentration

                         exceed the TLV or PEL.



        Ventilation:     Provide general ventilation and/or local exhaust if necessary to

                         maintain concentration below TLV.



        Eye Protection:         Safety glasses with side shields and/or face shields for

                                grinding; goggles or helmet for welding.



        Other: Protective apron and gauntlets when welding on or thermally cutting castings.



X.      Special Procedures:



        Storage requires no special requirements.
