Outside Municipal Emergency, Firefighting Personnel and First Responders
Emergency professionals must be informed of the pres- ence of molten metal areas, the types of metal being melted in the plant and the associated hazards. Plant operations should be reviewed periodically with all emergency person- nel, including outside municipal emergency departments, firefighters and first responders.
Molten Slag
Slag must be allowed to cool completely in a con- trolled area before being moved outdoors to prevent
