A changing pattern of steel production is resulting in increased bulk shipment of iron and steel scrap and of DRI <direct-reduced iron>. Though most types of scrap do not present a fire hazard, the cheapest scrap, metal turnings, does; it consists of turnings and other scrap from machining operations, is often coated with oil, and may contain paper and other combustible materials. DRI, also a fire hazard, is categorised into two types for shipping purposes; the more hazardous consists of lumps, pellets and cold-moulded briquettes; the other, hot-moulded briquettes, is subject to less severe restrictions. Bulk non-ferrous metals, especially in powder form, can also be a fire hazard, and one of these, zinc skimmings <also known as zinc ashes, dross or residue> is also considered in this article; a brief account is included of an explosion and fire in this cargo, and of the subsequent U.S. Coast Guard enquiry. These three materials -- metal turnings, DRI, and zinc skimmings -- are discussed in relation to their general characteristics, the fire hazards present when they are carried in bulk, the countermeasures that can be taken against spontaneous combustion in the cargoes, and relevant IMO and U.S. Coast Guard safety codes.
