Firefighters perform search operations during fires in order to rescue people. Full-scale tests to evaluate the effectiveness of the techniques used to search a room have been organized in the absence of fire. 42 search crews completed 7 different set-ups. The crews consisted of Belgian and Dutch firefighters as trained to date. They searched four 12 m² bedrooms and three 31 m² office spaces. Searching an empty space was compared to searching a furnished space. The impact of using a hose line was evaluated. 4 min is a good order of magnitude for the search of a bedroom. The time needed increases with increasing surface, but not proportionally. Crews can search a larger area per unit of time in the 31 m² office than in the 12 m² bedroom. The average air consumption rate in the breathing apparatus is 68–70 lpm for both rooms. When using a hose, the search becomes longer in time and takes a higher air consumption rate (average: 84 lpm). The decision to take a hose line or not is therefore very important. Crews where the two firefighters are side by side are more effective than crews where they are behind the other.

消防员在大火中执行搜救行动，以营救人员。在没有火灾的情况下，已经组织了全面测试以评估用于搜索房间的技术的有效性。42名搜索人员完成了7种不同的设置。机组人员包括经过培训的比利时和荷兰消防员。他们搜索了四个12 m ²卧室和三个31 m ²办公空间。将搜索空白空间与搜索布置好的空间进行了比较。评估了使用软管的影响。4分钟对于搜索卧室来说是一个好数量级。所需时间随表面的增加而增加，但不成比例。人员可以在31米每单位搜索更大的面积的时间²处比在12米²卧室。两个房间的呼吸器平均空气消耗率为68–70 lpm。使用软管时，搜索时间会更长，耗气量也更高（平均：84 lpm）。因此，决定是否选择软管是非常重要的。两名消防员并排的乘员组比在另一方落后的乘员组更有效。
