                  通风柜的主要功能是将有害气体和物质从实验室中去除到外面,以保护实验室人员的安全,并减少实验污染物对人体的再污染。根据排气方式的不同,通风柜可分为三种类型:上排风式,下排风式和上下同时排风式。


                  通风柜的排气管通常与空调系统的排气管一起。为了使工作区域的排气风速与空调系统的排气风速相同,?#31995;?#30340;排气通常用于冷处理,而上排风式用于热处理,如果对于发热过程不稳定的工作环?#24120;?#21017;是采用上下同时排风的排风方式。


                  在实验室开始工作之前,应检查通风柜是否处于打开状态,如果通风柜正常打开可以进行实验操作,并?#20197;?#23454;验后,在离开实验室之前,在实验结束后至少15?#31181;?#20851;闭通风柜,保留15?#31181;?#25490;出引擎盖中的残余气体。当然,为方便起见,建议使用木材和?#31181;?#36890;风柜,安装通风柜延时关闭装置,使通风柜自动关闭。
