Emergency services and rescue services〔(Collins dictionary )〕 are organizations which ensure public safety and health by addressing different emergencies. Some of these agencies exist solely for addressing certain types of emergencies whilst others deal with ad hoc emergencies as part of their normal responsibilities. Many of these agencies engage in community awareness and prevention programs to help the public avoid, detect, and report emergencies effectively. The availability of emergency services depends very heavily on location, and may in some cases also rely on the recipient giving payment or holding suitable insurance or other surety for receiving the service. ==Main emergency service functions== There are three main emergency service functions: * Police — providing community safety and acting to reduce crime against persons and property * Fire department (fire and rescue service) — providing firefighters to deal with fire and rescue operations, and may also deal with some secondary emergency service duties * Emergency medical services (EMS) — providing ambulances and staff to deal with medical emergencies In some countries such as the UK, these three functions are performed by three separate organizations in a given area. However, there are also many countries where fire, rescue and ambulance functions are all performed by a single organization. Emergency services have one or more dedicated emergency telephone numbers reserved for critical emergency calls. In some countries, one number is used for all the emergency services (e.g. 911 in the U.S., 999 in the UK). In some countries, each emergency service has its own emergency number. 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「Emergency service」の詳細全文を読む スポンサード リンク
