Amagama angaphandle kwesigaba samamaski, njengemaski yokunakekela, amamaski angewona awokuhlinzwa,imaski yobuso elahlwayoisesitokweni, njll. Izinhlobo ezahlukene kanye nobubanzi bokusetshenziswa kwamaski kunqunywa kakhulu yizinkomba ezijwayelekile zemaski ezahlukene. Uhlelo olujwayelekile lwemaski lwaseShayina luqukethe amazinga ezinto ezibonakalayo, amazinga omkhiqizo kanye namazinga okuhlola.
Izindinganiso emkhakheni wokuvikelwa kwezokwelapha zifaka phakathi: YY 0469(imaski yokuhlinzwayokusetshenziswa kwezokwelapha), i-YY/T 0969 (imaski yokuhlinzwa elahlwayo) kanye ne-GB 19083 (imaski yokuvikela yokusetshenziswa kwezokwelapha); Izinga elijwayelekile emkhakheni wokuvikela impilo ikakhulukazi yi-GB/T 32610 (imaski yokuvikela yansuku zonke).
Lezi ezingenhla ziyizinhlobo ezivame kakhulu zamamaski esibhekana nazo ekuphileni kwethu kwansuku zonke. Kumamaski athengwe eziteshini ezivamile, amazinga omkhiqizo abhalisiwe angenhla aphrintiwe ngokucacile futhi ahambisana negama lomkhiqizo kufanele atholakale ephaketheni.
Amamaski angahlukaniswa ngezigaba ezine: A, B, C kanye no-D ngokusekelwe ku-PM2.5: ukungcola okukhulu, ukungcola okukhulu nokungaphansi, ukungcola okukhulu nokungaphansi, kanye nokungcola okumaphakathi nokungaphansi.
Ukuqhathaniswa kokusebenza kokuvikela kanye nezinkomba eziyinhloko zamamaski ahlukahlukene akunakulinganiswa, ngoba izinkomba zokuhlola zamamaski emkhakheni wokuvikela kwezokwelapha kanye nokuvikela okungewona okwezokwelapha zihlukile.
Izinkomba eziyinhloko zamamaski emkhakheni wokuvikelwa kwezokwelapha yilezi:
Ukusebenza kahle kwesihlungi samabhaktheriya, ukusebenza kahle kwesihlungi sezinhlayiya ezingezona uwoyela, ukungena kwegazi, ukumelana nomswakama womphezulu kanye nokumelana nokuphefumula, njll. Izinga lokuvikela: imaski yokuvikela yezokwelapha (njenge-N95)>Imaski yokuhlinzwa yezokwelapha >;Imaski yokuhlinzwa elahlwayo. Kodwa imaski yokuhlinzwa yezokwelapha imelana kakhulu nokungena kwegazi kanye nomswakama.
Izinkomba eziyinhloko zamaski okuvikela angewona awokwelashwa yilezi:
Ukusebenza kahle kokuhlunga izinhlayiya okungeyona i-oyili, ukusebenza kahle kokuhlunga izinhlayiya zamafutha, ezinye izinkomba akuzona izidingo eziqondile.
Ngakho-ke siyazi ukuthi ungakhetha imaski efanele kuye ngokuthi ukuphi. Izisebenzi zezempilo zomugqa wokuqala zivame ukugqoka imaski yokuhlinzwa, futhi kufanele zigqoke ungqimba olwengeziwe lwemaski yokuhlinzwa lapho zikhipha ama-nucleic acid noma zifafaza uketshezi lomzimba ezigulini ezinegciwane.
Kodwa empilweni yansuku zonke, abantu akudingeki bagqoke imaski yokuzivikela uma benenkinga yokuphefumula. Uma abafundi beya emakilasini, abantu abadala belanda izingane nsuku zonke, bethenga imifino eceleni komgwaqo, iziguli ezine-asthma kanye neziguli ezingezwani nokudla ukuze bavimbele impova, ukungcola komoya nezinye izimo, sebenzisa imaski yokuzivikela yansuku zonke engeyona eyezokwelapha. Kodwa-ke, imaski yezokwelapha kanye nemaski yokuhlinzwa enamandla okuvikela aqinile kufanele isetshenziswe kubantu abadinga ukuya eziteshini, ezikhumulweni zezindiza, ezibhedlela nakwezinye izindawo ezinobungozi obukhulu ezinabasebenzi abaningi kanye nomoya ongenamoya, kanye nabantu abadinga ukunakekela iziguli ezinezifo ezithathelwanayo kanye nokuhlanza nokuchaphaza empilweni yansuku zonke.
Yilokho kuphela okuphathelene namamaski. UJinhaocheng ungumkhiqizi wamamaski ochwepheshe, wamukelekile ukuza ukuzobonisana.
Isithombe semaski yobuso elahlwayo sikhona esitokweni
