documents: #Person1#: Could you just run through the evacuation procedure?
  #Person2#: Yes, of course. When you hear the fire alarm, which is a very loud, continuous ringing noise, you should go to the nearest fire exit or fire escape as quickly as possible.
  #Person1#: Should we use the stairs?
  #Person2#: Yes, don't use the lifts. We have regular fire drills so you'll soon become familiar with the procedure. And always shut the fire doors to prevent the fire spreading.
