Ngokuvamile amamaski angahlukaniswa ngezigaba ezimbili: amamaski okuvikela kanye namamaski ajwayelekile.
Amamaski asetshenziswa kakhulu ukuvimba umkhuhlane, kanti amamaski okuvikela asetshenziswa kakhulu ukuvikela impilo yansuku zonke nokusebenza ezintweni ezahlukahlukene. Ngokusho kwezinto ezivikelwe, amamaski okuvikela angahlukaniswa abe amamaski okuvikela nsuku zonke, amamaski ezokwelapha, amamaski ezimboni, kanye namamaski omlilo.
Izifihla-buso, izifihla-buso zemayini yamalahle njalo njalo.
Amamaski okuvikela ansuku zonke, aziwa nangokuthi amamaski omphakathi, abhekisela kulawo asetshenziswa empilweni yansuku zonke. Idivayisi yokuvikela egqokwa izakhamuzi zaseShayina ukuhlunga izinto ezincane emoyeni ongcolile. Kwabasebenzi abavela kuzo zonke izigaba zokuphila. Ngezidingo zabasebenzi bokusebenzisa amamaski, kokubili ekhaya nakwamanye amazwe bathuthukise amazinga athile adingekayo amamaski okuvikela, izinhlayiya. Kokubili ukuvikelwa ngokomzimba kanye nokumelana nokuphefumula kuyizivivinyo ezibalulekile zala mamaski akhethekile. Izazi zasekhaya nakwamanye amazwe zenze izifundo eziningi ngokuvikelwa kwama-granule azo zonke izinhlobo zamamaski, okuhlanganisa ucwaningo ngomthelela wejubane lokugeleza komoya ekusebenzeni kahle kokuhlunga kanye nocwaningo ngomthelela wejubane lokuphefumula ekusebenzeni kahle kokuhlunga, kanye nocwaningo ngokusebenza kahle kokuhlunga kwamamaski e-N95 ngaphansi kokujikeleza kanye nejubane lokugeleza eliqhubekayo. Kuleli phepha, izinga lokuvuza kanye nomphumela wokuhlunga wamamaski omlilo kwafundwa, futhi kwafundwa amamaski ezokwelapha namamaski e-N95.
Ucwaningo lokuqhathanisa ukusebenza kahle kokuhlunga kanye nokuthuthukiswa kochungechunge lwemishini yokuhlola ehlobene. Phakathi kwazo, ezintweni ezincane. Ukuvikelwa kuhloswe kakhulu ekusebenzeni kahle kokuhlunga kanye nokufaneleka kwezinto zokuhlunga.
Izakhiwo zokuvikela zemikhiqizo yemaski zikhuthaze intuthuko esheshayo nephumelelayo yemboni yemaski. Kodwa-ke, esikhathini esidlule, kwakukhona izindinganiso zemaski yezokwelapha kanye nezindinganiso zemaski yokuvikela yezimboni kuphela eShayina, okwaholela ekuphazamisekeni kwemakethe yemaski yomphakathi kanye nekhwalithi engalingani. Abantu babengazi ukuthi hlobo luni lwemaski olubafanele lapho bethenga imaski.
Ngomhlaka-1 Novemba 2016, i-GB/T 32610-2016, indinganiso yokuqala kazwelonke yaseShayina yamaski okuvikela umphakathi, Imininingwane Yobuchwepheshe yamaski okuvikela nsuku zonke, yaqaliswa ngokusemthethweni.
Indinganiso iyasebenza ekungcolisweni komoya empilweni yansuku zonke. Izifihla-buso ezigqokwa umphakathi ukuhlunga izinto ezincane azikwazi ukusetshenziswa kwezinye izindandatho ezine-hypoxia.Isivivinyo Sokumelana Nokuphefumulaesetshenziswa emvelweni, ekusebenzeni ngaphansi kwamanzi, ekubalekeni nasekucimeni umlilo nakwezinye izimboni ezikhethekile. Kuphinde kuchazwe ngokusobala ukuthi indinganiso ayisebenzi ezintweni zokuvikela ukuphefumula zezinsana nezingane. Umphakathi jikelele kufanele ukhethe izinto zokuphefumula zomphakathi ngokwezimiso ezintathu zokuvikela ukuphefumula, ukuphepha kanye nenduduzo yokuphefumula. Ngokusho kocwaningo, ucwaningo lwamanje mayelana nokuvikelwa nokuphepha kwamaski seluphelele, futhi ngokuthandwa kwamaski, abantu banaka kakhulu induduzo yokuphefumula yamaski.
Ucwaningo lwenduduzo yokuphefumula lugxile kakhulu ekugqokeni imaski yobuso lapho kwenziwa ucwaningo lokumelana nokuphefumula, ngokwezinga likazwelonke ezweni lethu okwamanje kukhonjiswa ukuthi umkhawulo wokumelana nokuphefumula okungaguquki kuphela, lo mkhawulo kanye nentuthuko yemboni yemaski, kancane kancane kunciphisa, imboni yemaski yesikhathi esizayo izobhekela ukuphepha okuphezulu, ukuvikelwa okuphezulu, ukumelana nokuphefumula okuphansi ekuqondeni kwentuthuko.
