The safety device is characterized in that the device can protect the people in the room from air pollution, more particularly the invasion of harmful substances or organisms. The inlet pipe is provided with at least one air pollution detector which is connected with a safety door via a control device; the safety door can hermetically close the inlet pipe when air pollution appears. The safety device has the advantage that air is treated with the technical proposal that the detector is arranged at the head of the inlet pipe and the safety door and the air treatment apparatus are arranged at the terminal of the inlet pipe so that one part of the waste air in the room can be reused as the feed air of the room.
(ZH) 本发明涉及建筑物至少一个房间内空气的安全装置，其中，该房间具有至少一个吸入外界空气的进气管道和至少一个空气处理装置。特别是安全装置的特征在于，防止房间内的人受到空气污染，特别是有害物质或者有机体的侵害。该目的由此得以实现，即在进气管道内设置至少一个空气污染检测器，通过控制装置与出现空气污染时气密关闭进气管道的安全门连接。具有优点的是，检测器处于进气管道的首端，而安全门处于其末端。在进气管道的末端上有空气处理装置。对房间的空气这样进行处理，从而使一部分房间废气可以重新作为房间的送入空气使用。
