Once a second crew is assigned or operating in the hazard area, the incident is no longer considered in the initial stages and a dedicated Firefighter Assist and Search Team or Rapid Intervention Crew is required. == Explanation == 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「Two-in, two-out」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.
