Disaster and emergency
Fire compartments and the escape route after the fire door closes
Fire compartments: the shortcut you use every day is the one that closes — a drill map must show the route after the shutters come down, not before

Notes in the source (in Japanese)
避難訓練でいちばん大事なのは、いつもの近道が閉まること。
防火戸とシャッターは煙感知で自動的に閉まる。だから訓練の図は「ふだんの経路」ではなく「閉まったあとの経路」を描く ——東階段まで 43m の道が、西階段まで 26m に変わる。
煙は天井を這って広がるので、防煙壁は天井から 50cm 下げ、排煙口は天井から 80cm 以内に付ける(令 126 条の 2・3)。竪穴区画は準耐火構造の床・壁か防火設備(令 112 条 11 項)。特定防火設備は面積区画・異種用途区画の側。距離は 1px=100mm で、事務室の同じ点から階段の中まで測った(東 42.6m、西 26.4m)。
