According to PD 1096, what is the minimum width of an exit door?

The minimum width of an exit door, as established by PD 1096, is specified to be 900 mm (or 0.9 meters). This requirement is designed to ensure that occupants can safely and swiftly exit a building in the event of an emergency, minimizing the risk of crowding and allowing for efficient evacuation.

A width of 900 mm strikes a balance between providing ample space for individuals to pass through, including those who may be using mobility aids, and accommodating the structural limitations and design considerations of various buildings. This regulation reflects the importance of safety in building design and aims to facilitate a quick exit from potentially hazardous situations.

Other options, such as 750 mm, 1 m, and 1.2 m, do not conform to the established minimum, as 750 mm is narrower than required for emergency egress, while 1 m and 1.2 m exceed the minimum width established in the code and are likely not required unless specified by additional regulations for particular types of buildings or circumstances.
