Personal Evacuation Plan??

[LollipopVioletsExplodingRocket]

OK, after a full year at uni, it's been decided I need one of these because of my visual impairment. So I'm having a meeting with my lecturer next week. But can someone tell me exactly what one is, maybe give a few examples? I want some info before the meeting, so that it doesn't all go over my head. Might be more relevant to lecturers if any of them are about?

They are all pretty much the same IME - there's a sample one here
