I was commissioning a new phone system for a customer and as part of the process we are required to test 000 or 112. Pretty easy, called the number gave then the approved speel of this is only a test call for a new phone system and asked them to tell me what number I was presenting.
Never had to call because of an actual problem.
Once working at the bottom of a radio tower with people up the tower. After about an hour and a half I remembered I should be wearing a hardhat.
5 min later one of the guys up the tower dropped a wrench and it hit pretty much where I was standing without the hardhat.
