During the First World War, the Metropolitan Police introduced their first air raid warning system in London in 1917, which consisted of police officers detonating maroons (a type of loud firework) and the "all clear" was sounded by Boy Scout buglers.〔Ian Frederick William Beckett (2006), ''Home Front 1914-1918: How Britain Survived the Great War'', The National Archives, ISBN 978-1-903365-81-6 p. 187〕 Immediately before the Second World War, a network of sirens had been established in towns across the United Kingdom; the "alert" was given given by a rising and falling tone and the "all clear" by a continuous tone. ==References== 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「All clear」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.
