Sign from a carriage of a State Rail train in Sydney.
The sign reads:
Emergency Procedure
1. If danger present move to another carriage
2. If you are last close the door behind you
3. Inform guard or driver of danger
4. Remain on the train
5. Follow instructions from crew
The question in response to 2 is:
What if the danger wants to follow you to another carriage, are they the last and should they close the door behind themselves?
