The Four Elements of Evacuation Information

1. Notification (What is the emergency? How will I be notified?)

2. Way finding (Where is the way out?)

3. Use of the way (Can I get out by myself, or do I need assistance? Do I need a device?)

4. Assistance (What kind of assistance might I need? Answer the questions: Who? What? Where When? How?)
