"""Emergency numbers differ from country to country. While 911 was eventually adopted as the standard number in the United States and Canada, in Europe you'll need to dial 112, although 999 also works in the UK, where there's been an emergency number system since the 1930s.   In contrast, 911 was not official until the late '60s, when it was first known as """"nine-eleven,"""" and then later changed to """"nine-one-one"""" to avoid confusion with people wasting precious time looking for the """"11"""" button.  Prior to the one-number system, you'd call the operator to summon the correct emergency service, although in the States some fire departments could be reached by dialling """"3-4-7-3"""" -- which spells """"FIRE."""""""
