(Be sure to keep the furnace pit area clean and dry.
• Direct Arc Furnace The Indirect Arc Furnace uses one electrode and works in much the same way as the Direct Arc Furnace. The Indirect Arc Furnace is a refractory-lined furnace in which the load is heated indirectly by the radiant heat from an electric arc. The use of this method is limited to the melting of cast irons and non-ferrous metals.
No specific fire or explosion hazard. Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode. Special protective equipment for fire-fighters Use an extinguishing agent suitable for the surrounding fire. Extinguishing media::: None known.

The first explosion referred to as the primary explosion is usually small with pressures less than 2 pounds per square inch, (psi). It propagates a pressure wave and fire front. The pressure wave moves away from the location of the primary explosion at a speed of about 1000 feet per second (fps) while the fire front follows at about 10 fps.
