My wife and I were eating some grapes last night and I contemplated on what will happen to me should I accidentally choke on one of them. I asked her if she knew how to perform the Heimlich maneuver, even though I already know the answer, which was no. She told me she will instead call 911. Of course, 911 is something which is used in the USA, but Switzerland also has equivalent emergency services. Unfortnately, more for me than for her, she also didn't know the emergency numbers in Switzerland. So I'm posting here some information on what to call in case something untoward happens. Note that this is the current known numbers, and that you should get in touch with your local Gemeinde if there are any specific contacts for your area. The Gemeinde also issues information mailed to your address either at the end or early of the year.
117 - Police
118 - Fire Department
144 - Ambulance
1414/1415 - Helicopter rescue (Rega)
145 - Poisoning emergencies
140 - Emergency roadside assistance
143 - The helping hand (I have absolutely no idea what this is about)
147 - Support for children and kids
There are also some miscellaneous services available. What I do not know is if dialing these numbers will incur you some additional cost on your landline bill.
161 - Talking clock
162 - Weather forecast
163 - Road conditions and traffic news
164 - Sports and lottery results
175 - Telephone fault assistance
187 - Avalanche reports
1600 - Regional/local information
0900 77 hh mm - Automated wake up call (Replace hh with hour and mm with minutes on what time you wish to be called)
Now that you have these numbers, there shouldn't be any reason why anyone has to die of choking by grape.
