A Study on Design Fires for Means of Egress in Office Buildings
The objective of the study is to establish the design fire for egress calculations taking into account the characteristics of combustibles as well as the sprinklers' fire suppression capabilities. We conducted: fuel load surveys, office furniture fire tests, and full-scale fire experiments representing typical office rooms.
The results showed that: 1) The quantity of plastic combustibles in the office space was increased over the past some 20 years due to the increased use of office automation equipment such as PCs, printers, copiers, etc.; 2) In the initial stage of a fire, the influence of the quantity and the arrangement of plastic combustibles is greater than that of the quantity of wooden combustibles; 3) Although combustion in the areas where the water did not reach (such as the space beneath the desk) continued when the sprinklers operated, the fire could be confined within a fire unit.
This research was carried out as a three-company joint research of Taisei, Shimizu, and Kajima Corporations.
