Development of the Safety Cabinet for Respiratory High-Pressure cylinder according to Consequence Analysis of Physical Explosion Damage

A fire station and scuba have operated filling facilities for respiratory high-pressure cylinder without getting authority or reporting according to High-Pressure Gas Safety Control Act. They need facility improvement and special management to make provision for the time of accident during filling process. The Government have strived to correct illegal operations and suggested an alternative, establishing and operating the safety cabinet. It insures a safety being distance from danger caused by overpressure and a safety provoked by the protective wall equals or superiors. The safety cabinet is required to have an internal structure that smoothly distribute overpressure at the time of rupture. Plus, it needs to minimize fragments. It is also equipped with the performance of protective wall that makes overpressure to outside vent on the place where there is no person (top or bottom). This study calculated the consequence of physical explosion damage and built a prototype of safety cabinet. In addition, through the gas burst test, it derives for the ways to mitigate the physical explosion damage.

Study on the safety management of toxic gas cylinder distribution using RFID

The usage of toxic gas has increased consistently by the needs of the high-tech industry. Unfortunately, the number of toxic gas accident has also increased and it might cause huge human and material damage which is occurred by toxic gas leakage and diffusion. Mainly, toxic gases are stored in cylinders, however, there is a high probability of abusing to terrorism for toxic gas cylinder and operators dealing with toxic gas manage their toxic gas cylinder individually. For these reasons, toxic gas cylinder needs tracking management on a national level. In this study, it suggests that the tracking management system of toxic gas cylinder using RFID (Radio-Frequency identification), which is able to handle systemati cally by data integrating with equal cylinder distribution in each company. It is essential that the data integration system of toxic gas cylinder must establish a standardized ID on each cylinder and manage the history of cylinder distribution on existing each system. This system is operating preliminarily on the three sites to verify. It is expected that accidents caused by terror will be dramatically reduced and the most advanced level of safety control will be achieved.
