Abstract
This paper describes the investigation into the actual condition of electrical equipments installation and management for establishing the countermeasures against the electric shock in submerged underground. The investigation was carried out for 27 underground premises in conurbation including Seoul, and potential of the exposed electrical equipments negatively affecting on human safety when disaster occurs was measured. The objects to which measurement was carried out were as follows; electrical source; advertising lighting; power equipment. As a result, it was confirmed that potentials more than 230[V] were induced in some equipments. In addition, the electrical equipments installed in most conventional underground premises were left unmanaged.
