雖然在商業建筑與多種居住房的被動消防中，防火閥是關鍵組件，但在對建筑和其居住者的安全保護中，很多管理者沒有意識到防火閥的作用以及規定時間間隔內，防火閥的檢測、清潔及維護的重要意義。在推薦防火閥商業建筑中的建造中我們總會遇到一些麻煩，試圖在能源效率與室內空氣質量之間尋求平衡就是其中。大多商業建筑通過機械通風或空調系統解決，能夠測量和控制整個建筑的空氣變化。在通風管道系統的安裝上就存在上面提到的問題———如何在延遲或防火閥阻止火(huo)災蔓延(yan)的(de)(de)建筑防火(huo)分隔(ge)與(yu)所(suo)允許空氣自由流(liu)通(tong)的(de)(de)需(xu)要(yao)之間達(da)到平(ping)衡(heng)。滿足(zu)空氣自由流(liu)通(tong)需(xu)要(yao)不可避(bi)免地再引入一(yi)條通(tong)道(dao)，而(er)這卻加快了(le)火(huo)勢的(de)(de)蔓延(yan)———利用通(tong)風管道(dao)系統使(shi)用的(de)(de)通(tong)道(dao)。毫無疑問，這中斷了(le)防火(huo)分隔(ge)，充當了(le)建筑被動消防護(hu)面的(de)(de)“裂口”。
