2004年美國一位女性於自助加油時，因摩擦帶電而造成火花之意外影片，雖未造成嚴重的損失與傷害，但此畫面給予大眾極大的震撼，使看不見的靜電危害受到了矚目。現今在台灣設有247家以上之自助加油站，且因應時代的趨勢，其數量必然不斷上漲。自助加油站減少了人力之成本帶來方便，但消費者轉換為未受過訓練及規範之顧客，使其操作過程擁有一定之不確定性；且難以察覺之靜電，其在操作者無意之間即可能生成、累積並放電造成危害，故本研究目的為探討現今自助加油站之靜電預防措施之效用，並給予適當之建議。本研究現場訪視15家自助加油站，蒐集其相關資訊並於現場量測設備之電導率，用以評估其導電性及效用。研究結果顯示：1.操作面板之金屬材質介面具有良好導電效果，其電荷散逸時間僅需0.3±0.12 秒；2.加油槍之把手部分通常使用塑膠套包覆，無法有效將消費者身體之電荷導掉（塑膠套電阻值：＞1,012 Ω；拆除膠套之電阻值：2 Ω）；3.加油機台本身即具有接地效果，具良好之導電性（18 Ω）；4.國人於油槍把手掛上抹布以保持清潔之動作，很可能增加電荷的累積引發靜電危害，故不建議使用抹布。根據研究結果，分析出現有之自助加油站設備導電性不差，可惜的是未能確實定期作檢測與維修，若能藉由教育訓練等方式，提升國人之靜電放電危害及預防相關知識及嚴格遵守適當之操作流程，則靜電危害之風險即可有效降低。另外，製作標準作業流程讓消費者皆能正確操作，使靜電預防措施發揮效用，有效避免靜電放電危害之發生。

In 2004, there was a famous self-refueling accident caused by electrostatic discharge (ESD) inAmerica, California, and it reminds people the potential risk of self service gas station. Taiwan hasmore than 247 self service systems and it will continue increasing, so we should take care about thisissue. Therefore, to explore the ESD hazard and its related prevention measures on self-refuelingoperation will be the key issue in Taiwan, and this is also the purpose of this study.We cooperated with 15 gas stations to collect some information, and to explore the most commonmethods used for electrostatic hazard prevention in self service gas station in Taiwan, then to measurethe electrostatic condition on necessary area when refueling.According our research, we found the electric resistance of gasoline is very high, the averagevalue is 0.04 pS/m (0.04±0.05 pS/m). We also test some electrostatic prevention methods, such as:1. removed the billet from gasoline pump nozzle, and customers would not jam the pump nozzle andtouch other area when they refueling; 2. ESD eliminating bottom, or conductive operation keyboard(discharge time：0.30±0.12 second), keep them could conducting the charge which stay on person;3. gasoline pump nozzle and operation relative pipe with metal materials, and we test grounding resistance of gasoline dispenser, periodically; 4. removed the plastic sheath from handle, to increasethe conductivity ( plastic sheath resistance：＞1012 Ω; removed plastic resistance：2 Ω). Thosemethods also exhibited a good effect of ESD prevention at the good maintenance condition. Besides,the method of hang a piece of cloth on nozzle may produce more electrostatic charge, and make apotential risk.Base on the study results, we give some suggestion to self-refueling operation. We hope thesuggestion can effectively minimize the risk of ESD hazard on gas station.
