Abstract
High-tech process is the most important for economic activity of Taiwan, because the process requires a lot of special gases, chemicals and complexity of fully automated machine equipment, came when all fires, explosions, chemical leaks or power outages and other disasters, in addition to causing personal injury, also shut down the processing and because operation can not be sustained.
This study will be A's case, we use risk assessment techniques to analysis characteristic of process, and we started on-site reviewed the structure of special gas supply system, and reviewed gas storage room of situation now, after first stage we confirmed the gas cabinets system, gas cabinets main piping, VMB, supplies system of silane gas, reactors, blowers exhaust systems, combustion control, combustion ventilation tube, and this tube to acid gas exports exhaust systems is main research items of ours, then we use them to assist risk and establish improvements; this study to verify the improvements are effective, then revised in the maintain project of year-end to confirm effectiveness.
After improvements accomplished, we got 49% improved of safety incidents for special gas supply system continuous operation of 3676 hour, we replacement 287 cylinders due to March until July in 2011, we do not have any incidents, and it is strong support the effectiveness of our research.
