Pretty straight forward so far but approved document b states that the door of any doorway or exit should if reasonably practicable be hung in the direction of escape and should always do so if the number of persons that might be expected to use the door at the time of the.
Emergency exit door opening direction.
D emergency doors must open in the direction of escape.
If there is a fire in the area where occupants are they are already being exposed to smoke fire and heat.
There should be no locks or catches.
Keep exit route doors free of decorations or signs that obscure the visibility of exit route doors.
Exit routes must be at least 28 inches wide at all points.
The qualifications for an emergency exit are as follows.
An emergency exit in a structure is a special exit for emergencies such as a fire.
The intent of d2 20 b is to ensure that egress from or into a required exit is not impeded by a door that swings against the direction of travel.
The same requirements as above will apply to a fire exit door.
Fire exit doors should open in the direction of escape.
The door should open in the direction of evacuation.
Post signs along the exit access indicating the direction of travel to the nearest exit and exit discharge if that direction is not immediately apparent.
D2 20 b therefore requires certain doors to swing in the direction of egress.
An opening into an exit must be protected by a self closing fire door that remains closed or automatically closes in an emergency upon the sounding of a fire alarm or employee alarm system.
During evacuation there could be crowding at an exit door.
The more people use a building the greater the number of fire exits.
This crowding could impede or prevent a door from being opened.
Also the line of sight to an exit sign must be clearly visible at all times.
Exit routes must be unobstructed and free from.
Many use a push bar system that will open the door when pressed down.
The nfpa emergency exit door requirements code states there is a maximum travel distance allowed to find an exit.
An exit is permitted to have only those openings necessary to allow access to the exit from occupied areas of the workplace or to the exit discharge.
However in the workplace it may be permissible to have an exit door opening inwards if it is providing excess for less than 60 staff without public access.
The combined use of regular and special exits allows for faster evacuation while it also provides an alternative if the route to the regular exit is blocked by fire etc.
Doors that connect any room to an exit route must swing out in the direction of travel.
