Uma kungekho ukwelashwa okucacile kwale coronavirus entsha, ukuzivikela kuyinto eza kuqala. Amamaski angenye yezindlela eziqondile nezisebenzayo zokuvikela abantu. Amamaski asebenza kahle ekuvimbeleni amaconsi futhi anciphise ingozi yokutheleleka emoyeni.
Kunzima ukuthola imaski ye-N95, abantu abaningi abakwazi. Ungakhathazeki, imaski ye-n95 ayihlukile kumaski okuhlinzwa maqondana nokuvikelwa kwegciwane/umkhuhlane, ngokusho kocwaningo lwezokwelapha olwanyatheliswa kuyijenali yenhlangano yezokwelapha yaseMelika ngoSepthemba 3, 2019.
Imaski ye-N95 ingcono kunemaski yokuhlinzwa ekuhlungeni, kodwa ifana nemaski yokuhlinzwa ekuvimbeleni igciwane.
Qaphela ububanzi bezinhlayiya ezingahlungwa zemaski ye-N95 kanye nemaski yokuhlinza.
Amamaski e-N95:
Kubhekisele ezinhlayiyeni ezingenamafutha (njengothuli, inkungu yopende, inkungu ye-asidi, amagciwane amancane, njll.) kungafinyelela ku-95% wokuvaleka.
Izinhlayiya zothuli zingaba zinkulu noma zincane, okwamanje ezaziwa ngokuthi i-PM2.5 ububanzi obuncane beyunithi yothuli, okubhekisela ubukhulu obungama-micron angu-2.5 noma ngaphansi.
Ama-microorganism, okuhlanganisa isikhunta, isikhunta, namabhaktheriya, ngokuvamile asukela ku-1 kuya ku-100 microns ububanzi.
Amamaski:
Ivimba izinhlayiya ezinkulu kune-4 microns ububanzi.
Ake sibheke ubukhulu begciwane.
Ubukhulu bezinhlayiya zamagciwane aziwayo busukela kuma-micron angu-0.05 kuya kuma-micron angu-0.1.
Ngakho-ke, kungakhathaliseki ukuthi usebenzisa i-antivirus ye-N95 mask, noma usebenzisa i-surgical mask, ekuvimbeleni igciwane, akungabazeki ukuthi ukusebenzisa i-rice sieve powder.
Kodwa lokho akusho ukuthi ukugqoka imaski akusebenzi. Inhloso eyinhloko yokugqoka imaski ukuvimba amaconsi athwala igciwane. Amaconsi angaphezu kwama-micron angu-5 ububanzi, futhi kokubili i-N95 kanye nemaski yokuhlinza zenza umsebenzi kahle kakhulu. Lesi yisona sizathu esiyinhloko sokuthi kungani kungekho mehluko omkhulu ekuvimbeleni igciwane phakathi kwala mamaski amabili anokusebenza okuhluke kakhulu kokuhlunga.
Kodwa okuphawuleka kakhulu, ngoba amaconsi angavinjelwa, amagciwane awakwazi. Ngenxa yalokho, amagciwane asasebenza aqoqana engqimbeni yesihlungi semaski futhi asengaphefumulwa ngesikhathi sokuphefumula okuphindaphindiwe uma egqokwa isikhathi eside ngaphandle kokushintsha.
Ngaphezu kokugqoka imaski, khumbula ukugeza izandla zakho njalo!
Ngikholwa ukuthi ngemizamo yochwepheshe abaningi, izazi kanye nabasebenzi bezokwelapha, usuku lokuqeda leli gciwane alukude.
