Can you please help me check these school rules in case of an evacuation?

1) During an evacuation you have to (must?)
2) stay calm
3) queue with the respective openline and closeline
4) go calmly to the nearest emergency door
5)if you need, go down the stairs, always quietly
6) go to the own meeting place
don't run, shout or push

All look fine except that each needs a period at the end.

#6 - I don't understand "the own meeting place" - What does that mean?
