The safe lodges (green dot) scheme is an Oxford University Security Service (OUSS) initiative. Students in distress can go to the nearest lodge - not necessarily their own - and receive help and support.
How does this work?
From the street
Any student in distress can go into any lodge displaying a green dot
At the Lodge
Use of a telephone
Place of sanctuary
Support from the porters/lodge staff
The lodge can then call the student's home college, who will then take responsibility.
In serious cases the OUSS or police can be called.
