Six standardized alarms are used on submarines of the United States Navy to alert the crew to situations that require immediate actions to be taken without waiting for specific orders. A higher priority alarm will silence an already-sounding lower one; in order of priority, they are: # Collision Alarm # Diving Alarm # Missile Emergency Alarm # Missile Jettison Alarm # General Alarm # Power Plant Casualty Alarm The two missile alarms are used only on submarines that carry missiles. A mnemonic aid for the order is the question "Can Dead Missile Men Get Pro-Pay?" == Collision/Flooding Alarm == The collision alarm is used to warn of imminent collision or actual flooding and is accompanied by a succinct statement of the emergency such as "flooding in engine room lower level" (if possible; flooding is deafeningly loud). The alarm is a slowly rising and falling siren, rather like a stereotype American police car siren, which sounds continuously as long as the switch is held on. The collision/flooding alarm handle is a red cog shape. 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「Alarms on submarines of the United States Navy」の詳細全文を読む スポンサード リンク
