1, lapho kuhambisana nongqimba lokuhlobisa noma ungqimba lokugeleza luhlelwe endaweni yokuphakelwa komoya engxenyeni engezansi ye-plenum,isihlungiisilinganiso esigcwele akufanele sibe ngaphansi kuka-0.75.
2. Uma ihlelwe ohlangothini lwe-plenum, ingahlelwa ohlangothini olulodwa noma ngakolunye uhlangothi.Isilinganiso esigcwele sesihlungi ohlangothini akufanele sibe ngaphansi kuka-0.75, futhi ukugeleza komoya ku-plenum kufanele kuhlanganiswe ngokugcwele.
3. Uma kunqunyelwe ukuphakama nokugcinwa kwasendlini kungavunyelwe, isihlungi singahlelwa ngaphandle kwe-plenum ngendawo yokuhlinzeka komoya enomsebenzi wokumelana nokuvuza, kodwa kufanele sibe seduze ne-plenum ngangokunokwenzeka, kanye nokugeleza komoya endaweni. I-plenum kufanele ihlanganiswe ngokuphelele.Isilinganiso esigcwele somoya ohlanzekile kufanele sibe ngaphansi kuka-0.85.
4. Ezindaweni ezihlanzekile ezingaphansi kwebanga le-100, lapho isikhumulo sezindiza sihlelwa phakathi nendawo, isigaba sokugcinaIsihlungi se-HEPAembobeni yokuphakelwa komoya ingahlelwa phakathi nendawo noma ihlakazwe, kodwa isendlalelo sokwabelana ngokugeleza kufanele simiswe endaweni yokuphakelwa komoya.
5. Wonke amagumbi ahlanzekile egunjini lokusebenza lokugeleza kwe-laminar kufanele asebenzise umoya obuyayo ovela emazweni amabili;Uma ibanga phakathi kwezinhlangothi ezimbili lingeqi ku-3m, ukubuya komoya ngaphansi kohlangothi olulodwa kungasetshenziswa, kodwa amakhona amane noma izinhlangothi ezine akufanele zisetshenziswe.Amaphasishi ahlanzekile namaphasishi ahlanzekile angasebenzisa umoya obheke phezulu.
6. Umoya obuya endlini kufanele usetshenziswe kuwo wonke amagumbi okusebenza okugeleza kwe-laminar enamazinga ayi-100, futhi akukho valvu yokucindezela eyinsalela okufanele imiswe ukuze kubuyiselwe umoya emhubheni.
7. Imbobo engenhla kufanele imiswe egumbini lokuhlinza lokugeleza kwe-laminar elisezingeni eliyi-100, futhi indawo kufanele ibe phezu kwekhanda lesiguli.Isivinini sokuqhuma kwendawo yokukhipha umoya akufanele sibe ngaphezu kuka-2m/s.
