Meeting rooms, activity rooms, rest rooms, locker rooms and other places are located within the area affected by the lifting and transporting of molten iron, molten steel and liquid slag.
-
Cranes used for lifting molten iron, molten steel and liquid slag do not meet the relevant requirements for metallurgical cranes; in steelmaking plants, when lifting heavy ladles of molten iron, molten steel or liquid slag, fixed gantry hook casting cranes are not used; the gantry hook crossbeam, trunnion pins, крючки, wire ropes and their end fixing parts are not periodically inspected, and identified problems are not promptly rectified.
-
The trunnions of vessels (such as ladles, pots and basins) containing molten iron, molten steel and liquid slag are not subject to periodic non-destructive testing as required by national standards.
-
Accumulated water and flammable and explosive materials exist in safety pits and within the area affected by melt leakage and splashing in smelting, melting and refining production areas. In metal casting, continuous casting and pouring processes, emergency discharge and emergency storage facilities for high-temperature molten metal, such as molten iron ladles, molten steel ladles, overflow troughs and intermediate overflow tanks, are not provided.
-
The main bodies and auxiliary facilities of furnaces, kilns, tanks and vessels are not periodically inspected; they continue to be used without reporting for repair or scrapping when serious weld cracks, corrosion, damage, lining brick deterioration, shell reddening and obvious bending deformation occur.
-
Water-cooled elements such as oxygen lances are not equipped with detection and alarm devices for outlet water temperature and inlet-outlet water flow difference, as well as temperature monitoring, and are not interlocked with furnace tilting, oxygen opening/closing, и т. д..
-
Gas holders are constructed in densely populated areas and are not located away from important facilities such as large buildings, warehouses, communication and transportation hubs; auxiliary equipment and facilities are not equipped with explosion-proof devices according to fire and explosion protection requirements; lightning protection devices are not installed on the top of the gas holder.
-
Fixed carbon monoxide monitoring and alarm devices are not installed in places where personnel are concentrated in gas areas, such as duty rooms and operation rooms.
-
Reliable isolation devices and purging facilities are not provided on the gas pipelines of blast furnaces, converters, нагревательные печи, gas holders, dust collectors and other facilities.
-
Reliable shut-off devices are not installed at the branch pipe connections on the main gas distribution header; in the workshop, main header shut-off valves are not installed at the entrance for various gas pipelines.
-
The main person in charge and safety production management personnel of metal smelting enterprises have not passed the assessment as required by law.
