Izici zomkhiqizo:
1. Okungasuswa, ukusetshenziswa okukodwa, ukuphefumula, ukukhanya nokuthanda imvelo;
2. Izinga eliphakeme lendlebe eliswelayo phezulu lilingana nabasebenzisi abahlukile kanye nokunamathiselwa kwephuzu elikabili kusiza ukuhlinzeka ngophawu oluphephile;
3. Isiguquli sekhala esilungisekayo senduduzo eyengeziwe;
4. Okungenani ukusebenza kwama-95% kokuhlunga ngokumelene nezinhlayiya ezithile ezingewona uwoyela.Ukusebenza kokuhlunga kwamaski we-kn95 ebanga izinhlayiya ezinobubanzi be-aerodynamic ≥0.3µm ungaphezulu kwama-95%. Ububanzi be-aerodynamic bamagciwane asemoyeni nomoya wokukhunta ikakhulukazi buhluka phakathi kuka-0.7- 10µm, okubuye kube phakathi kobubanzi bawo bokuvikela.
Ngakho-ke, lolu hlobo lwemaski lungasetshenziselwa ukuvikela ukuphefumula kokuthile kwezinto eziyizinhlayiyana, njengokugaya, ukuhlanza nokucubungula uthuli olwenziwe ngamaminerali, ufulawa nezinye izinto. Gxila ndaba kagesi oyingozi oyingozi.
Ungahlunga ngempumelelo futhi uhlanze iphunga elibi elenziwa ngaphakathi (ngaphandle kwamagesi anobuthi), isize ekunciphiseni izinga lokuvezwa kwezinhlayiyana ezithile ezingonakalisi (ezifana nesikhunta, i-anthrax, isifo sofuba, njll.), Kepha akunakuqeda ukutheleleka kokuxhumana, ukugula noma ingozi yokufa .

 Amaphuzu Okunakwa:
1. Lo mkhiqizo wenqatshelwe ukuthi usebenzise iphakethe elonakalisiwe;
2. Ungasebenzisi kumkhathi oqukethe i-oksijini engaphansi kwe-19.5%, ngoba lokhu kuphefumula kunganikeli umoya-mpilo; Ayisetshenziswanga kumoya we-oyili omubi;
3. Uma umkhiqizo ulimala, ungcolile, noma uphefumula iba nzima, shiya leyo ndawo ingcolisiwe ngokushesha bese ubuyisela umkhiqizo;
4. Lo mkhiqizo ukusetshenziswa kwesikhathi esisodwa kuphela futhi awukwazi ukugeza;
5. Lo mkhiqizo kufanele ugcinwe endaweni ehlanzekile, eyomile futhi enomoya omncane enomswakama wesihlobo esingaphansi kwama-80% futhi ngaphandle kwegesi eyingozi.
