Now a days, the monitoring system based on high technology and brand new IT which is being used in a facility for the purpose of monitoring the concentration of hazard chemicals and deformation such as crack has reached a significant level. However, the operating and maintenance cost for monitoring system is critical and therefore, it is unsuitable to use for monitoring urban local disaster and integrated emergency management, including indications of NEMA, and for the application of disaster management. For the past 10 years, the main cause for the fire and explosive accident was human error, and the accident rate was more the than 35% in South Korea. This sentence proves the fact that even if the safety device is well equipped, there are high possibilities to occur the disaster by simple human mistakes and it is impossible to neglect the accident. In order to minimize the disaster, comprehensive accident prevention system is required where it could operate and produce all the information needed for accident and accident prevention.In this study, we have considered above conditions, and tried to come up with integrated monitoring system where it could response to both hazard material and collapse threats. First, we divided the disaster area into two parts which are hazard material and collapse with deformation, and then proceed the development separately. Our purpose was to combine both toxic gas monitoring system and collapse monitoring system into one. trough our 3 years of research, the two different types of sensors have been developed and by using these sensors, the integrated early-warning system for monitoring of disaster symptom has been constructed and also the response manual has been made to improve the efficiency. With our integrated early-warning system, we provide the prototype of emergency plan and system for both chemical and contractual disaster, and we expect to be commercialized so that it will minimize the casualties whenever unexpected accident occurs.
