To perform water drainage quickly without the effect of environment contamination, contamination of surrounding devices, corrosion damage and chemical-induced suffering on a worker by inspecting the kind of water leakage by an automatic identifying device and selecting the dedicated drainage system based on the kind of the water leakage.
When water leakage occurs from a production drain pipe 6 of a production device 5, the generation of the water leakage is detected by a water leakage detecting tape 2 attached to a floor surface 1. Warning is issued from a warning device provided in an emergency drainage control plate 7 and reported to a controller. At the same timer the leaked water is contained in a leaked water receiving tank 8 and sent to a leaked-water discharging pipe 9. The kind of the leaked water is automatically identified by an automatic identifier 10 for the kind of the leaked water, which is assembled in this water leakage pipe 9. The kind of the identified water leakage is displayed on the emergency drainage control plate 7. The emergency drainage control plate 7 selects the dedicated drain pipe, that is to say, any of emergency drain pipes 11a, 11b, 11c, and 11d and connects the valve to the drainage system. Thus, the work for investigating the component of chemical, which is leaked by the worker, can be saved.
