suggested solution
In order to fulfill the above fire safety objectives, the following solutions have been suggested.
5.1. Transfer floor and transfer passageway
(1) Transfer floor and transfer passageway should be designed and there should be no combustibles inside the transfer
lobby on the transfer floor. Independent mechanical smoke exhaust system or natural smoke exhaust system with opening
area not less than 5% of the room area should be installed to secure the safety of the occupants during evacuation through
the transfer floor. Rooms connecting to the transfer lobby should be protected by class B fire door[3].
(2) On the transfer floor, the staircase and fire lift should be designed for two way evacuation[4-5].
