翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Gas-free engineer ： ウィキペディア英語版 Gas-free engineer A gas-free engineer (GFE) is a person who has successfully completed a similarly named training course offered by the United States Navy. The gas-free engineer is thereby qualified to certify a confined space as being safe to enter without the use of an air-purifying or supplied air (SAR/SCBA) respirator. The confined space would, however, need to be ventilated during entry to ensure an adequate supply of breathable air. Gas Free Engineering is equivalent to Firefighter team lead, Toxic Gas inspector, Confined space inspector, etc. == References == (U.S. Navy ) GFE Resources Index Actually the Navy Gas free course does not certify you to be a Gas Free Engineer. You are certified as a competent person for Gas Free spaces, To conduct hot work per OSHA standards, you have to use a certified Marine Chemist. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gas-free engineer」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
