簡易担架を用いた階段上昇避難支援における搬送準備時間及び垂直搬送効率

摘要

The purpose of this study is to compare and analyze the attributes of male and female subjects (evacuation supporters), transportation preparation time according to the size of transportation preparation space, and vertical transportation efficiency of stair ascent. For this, this study reenacted transportation situations of vulnerable people using stretchers and measured the transportation preparation time, the transportation speed and vertical transport efficiency of stair ascent transportation. As a result, in case of minimum operating space for transportation preparation, it was found that there was more than one minute of waiting time to start evacuation support actions. In addition, the transportation amount was around 0.02〜0.25persons/sec， and the transportation amount of the condition 2(condition of starting in a queue) that started transportation in a straight line was higher than the condition l(condition of starting from scattered points). And the transportation amount of the female transportation team was relatively lower than the male transportation groups.%2011年の東日本大震災以後、南海トラフ巨大地震などによる津波発生が懸念されている現在、津波来襲時避難の重要性はより高まっている。特に、自力での避難が困難な災害時要援護者の場合、津波避難ビルに到達した後も一定階以上の安全な階まで階段を上がって避難する必要がある。この時、避難方法や避難そのものに困難が伴い、避難に時間がかかると共に多数の避難支援者の支援が必要であると予測される。このため、津波来襲時の避難誘導や避難支援活動が可能な時間などを考慮するため、要援護者避難支援において、多数の避難支援者による搬送準備から搬送完了までの過程について予め検討しておく必要がある。
