潔(jie)(jie)凈(jing)(jing)實(shi)(shi)驗(yan)室(shi)(shi)(shi)分為普(pu)(pu)通(tong)潔(jie)(jie)凈(jing)(jing)實(shi)(shi)驗(yan)室(shi)(shi)(shi)與生(sheng)物(wu)安全實(shi)(shi)驗(yan)室(shi)(shi)(shi)。普(pu)(pu)通(tong)潔(jie)(jie)凈(jing)(jing)實(shi)(shi)驗(yan)室(shi)(shi)(shi)中進行的實(shi)(shi)驗(yan)不(bu)具有傳(chuan)染(ran)性(xing)，但要(yao)求(qiu)(qiu)環境對實(shi)(shi)驗(yan)本身不(bu)造成不(bu)良影響，因此實(shi)(shi)驗(yan)室(shi)(shi)(shi)內不(bu)設(she)防(fang)護(hu)設(she)施(shi)，而(er)潔(jie)(jie)凈(jing)(jing)度(du)必須達到(dao)實(shi)(shi)驗(yan)要(yao)求(qiu)(qiu)。生(sheng)物(wu)安全實(shi)(shi)驗(yan)室(shi)(shi)(shi)是具有一(yi)級(ji)防(fang)護(hu)設(she)施(shi)的，可實(shi)(shi)現二級(ji)防(fang)護(hu)的生(sheng)物(wu)實(shi)(shi)驗(yan)定。

　　凡(fan)進行微生(sheng)物(wu)學、生(sheng)物(wu)醫學、功能實(shi)驗(yan)(yan)(yan)及基因重(zhong)組等領域的科學實(shi)驗(yan)(yan)(yan)均需要生(sheng)物(wu)安(an)(an)全實(shi)驗(yan)(yan)(yan)室(shi)。生(sheng)物(wu)安(an)(an)全實(shi)驗(yan)(yan)(yan)室(shi)的核心是安(an)(an)全，依據(ju)生(sheng)物(wu)學危險程度劃(hua)為P1、P2、P3、P4四個等級(ji)(ji)實(shi)驗(yan)(yan)(yan)室(shi)設(she)雙重(zhong)門(men)或氣閘(zha)室(shi)和(he)外(wai)部隔(ge)離的實(shi)驗(yan)(yan)(yan)區域，非本(ben)處(chu)工(gong)作(zuo)人員(yuan)禁止入內(nei)，實(shi)驗(yan)(yan)(yan)室(shi)內(nei)全負壓，使用(yong)II級(ji)(ji)生(sheng)物(wu)安(an)(an)全柜(ju)進行實(shi)驗(yan)(yan)(yan)，以高效過濾器把室(shi)內(nei)空氣過濾后排(pai)到室(shi)外(wai);采用(yong)獨(du)立的建(jian)筑物(wu)內(nei)隔(ge)離區和(he)外(wai)部隔(ge)斷的構(gou)造，室(shi)內(nei)保(bao)持負壓，使用(yong)III級(ji)(ji)生(sheng)物(wu)安(an)(an)全柜(ju)進行實(shi)驗(yan)(yan)(yan)，設(she)置(zhi)(zhi)空氣隔(ge)斷裝置(zhi)(zhi)，淋浴室(shi)，操作(zuo)工(gong)作(zuo)人員(yuan)應穿防護(hu)服(fu)，非本(ben)處(chu)工(gong)作(zuo)人員(yuan)禁止入內(nei)。

　　生(sheng)物安(an)全實驗室設(she)計(ji)上的核心是動態隔離，排風措施是重(zhong)點(dian)，強調就(jiu)地消毒，重(zhong)視潔污分流(liu)，防止意(yi)外擴散(san)，需(xu)要適(shi)度(du)潔凈。
