What is the fire stairs in the civil works?
High-rise buildings are generally the most worried about fire problems, and set up fire stairs can solve unexpected problems, fire stairs are generally closed, need to install fire doors in the entrance, if the fire door intact, pyrotechnics is simply not get, The stairs are separate channels separate from the residence and can be used as an emergency evacuation channel when a fire occurs.
Where the obstacles can not be wiped out so that the fire can be evacuated.
Into the fire stairs to enter the safe area!
