I have a building were they are making metal products by multiple processes 
including Metal Casting of steel, Metal Forging, Additive Manufacturing and hot 
rolling. Most of the building is open warehouse where they are producing metal 
products with 3D printers.  NFPA has metal workings listed as ordinary hazard 
but also has Die Casting and Metal extruding under Extra hazard group 1. Does 
anyone know where I would start to figure out what hazard is required for this 
building?
