ICE: In Case of Emergency
From Wanda Lust, a pretty good idea:
Following the disaster in London on Thursday, a national campaign to help emergency service workers identify and contact family members has gathered national attention. The concept of ICE (In Case of Emergency) is simple: enter the acronym ICE into your mobile phone contact list, along with the name and numbers of someone you'd like to be contacted in the event of an emergency. Emergency staff will then know who to contact on your behalf.
