甲醛是日常生活中和在工業上被普遍使用的有毒物質。環境中所充斥之不同濃度甲醛氣體,對人體健康與感受皆具有不同之影響。甲醛對皮膚及黏膜有刺激性作用,接觸過甲醛的皮膚可能出現過敏現象,嚴重者甚至會導致肝炎、肺炎及腎臟損害。本研究以專業化學、物理感測器研發製造之U公司的PFD03甲醛氣體偵測器設備為例,運用FTA、FMEA技術與自主檢查規劃來降低產品檢測成本、提升品質良率與設備生產力。 本研究之主要嘗試運用FTA、FMEA技術來建構設備失效模式的風險優先數值(Risk Priority Number, RPN)並且將其轉換成自主檢查之建立,並且有效訓練員工技術能力提升整體設備總和效益(Overall Equipment Efficiency, OEE)。
Formaldehyde is a poisonous substance generally used in both daily life and industry. Formaldehyde gas exists in our environment in various concentrations causing various effects on the health and well-being of human beings. Formaldehyde has an irritating effect upon the skin and mucous tissues. Exposure to formaldehyde can lead to allergic responses, hepatitis, pneumonia and renal damage. This study is involved in PFD03 formaldehyde gas sensor equipment from professional chemistry and physical sensors invented by the U company. This equipment program takes advantage of FTA, FMEA techniques and self-examination planning to lower the product and detect costs in increasing the quality of equipment production. This study applied FTA and FMEA techniques to construct the Risk Priority Number for equipment mode loss effects and transformed it into self-examination. The production staff will be trained in these techniques to increase Overall Equipment Efficiency.
