12.1.1.1-6 Hinged Door Opening Direction

The discussion below addresses hinged door opening directions.

 

  1. When the normal traffic density and the exiting personnel traffic in emergency conditions are expected to be low, hinged doors should open inward rather than outward into a corridor.
  2.  

  3. When exiting traffic volume is expected to be high, hinged doors should have a see-through window and open outward to ensure the feasibility of exiting in an emergency. HFDS
