Not a typical entry about light this time, but a hopefully helpful hint anyway: Rescue workers often don’t know whom to call in case of emergencies. Even though most people have a mobile phone, it usually has so many entries that it is difficult to decide, whom to call FIRST.

Therefore it is an international recommendation to use the short “ICE” (for: In Case of Emergency) and connect it with the phone number of the first person you wish to be called in an emergency. If you want more than one people to be contacted, you can save them under ICE1, ICE2, ICE3 and so on.

This is free and doesn’t cost anything. The more people do it, the better it will be recognized internationally. Therefore please pass this information on to your friends, family and collegues.
