Masiki akajairika anosanganisira: mamasiki edonje,Masiki anoraswa(semuenzaniso, mamasiki ekuvhiya, mamasiki ekuvhiya), uye mamasiki ekudzivirira ekurapa (masiki eN95/KN95).
Pakati pazvo, masks ekudzivirira ekurapa (N95/KN95 masks) uye masks ekuvhiya ekurapa zvese zvigadzirwa zvekurapa zvakatongwa nehurumende kubvira paSARS muna 2003, uye zvine basa rekudzivirira kufamba kwemvura nemadonhwe. Kana zvikapfekwa zvakanaka, zvinogona kudzivirira zvirwere zvinotapukira. Ndiyo sarudzo yedu yekutanga yemasiki.
N95 harisi zita rechigadzirwa chaicho. Chigadzirwa chinosangana nechiyero cheN95 uye chakatenderwa neNIOSH chinogona kunzi chifukidzo cheN95.
MuChina, masks eK95 anoreva kupatsanurwa kwema masks ezvimedu zvisina mafuta zvichienderana nechiyero chenyika cheChina cheGB2626-2006. Kirasi yeKN yakakodzera kusefa zvinhu zvisina mafuta. Chikamu chedhijitari chenyika mbiri idzi chine chiyero chimwe chete. 95 inoreva kushanda zvakanaka kwekusefa ≥95%.
Kubva pamaonero e microbiological, sarudzo yakanakisisa i medical respirator inotevedzera mitemo, isingapindi mweya (N95/KN95 respirator)
Masiki ekudzivirira ekurapa anofanira kusangana nezvinodiwa zveChinese GB 19083-2010 pamwe nekushanda zvakanaka kwekusefa ≥95% (uchishandisa bvunzo yezvinhu zvisina mafuta). Zvinodiwa kuti upfuure bvunzo yekupinda muropa yakagadzirwa (kudzivirira mvura yemuviri kuti isapararire) uye kuti usvike pazviratidzo zvehutachiona.
Masiki ekuvhiya anoshandiswa zvakanyanya mumakamuri ekuvhiya nedzimwe nzvimbo uko kune njodzi yekupfachukira kwemvura yemuviri neropa. Anogona kudzivirira ropa nemvura yemuviri kuti isapfuure nepamasiki uye kusvibisa munhu anoapfeka. Panguva iyi, ane simba rekusefa rinodarika 95% remabhakitiriya.
Mavhairasi ndiwo tumapundu tudiki twatinokwanisa kuwana zuva nezuva. Tinoziva PM2.5, iyo inoreva tumapundu tune saizi ye2.5 microns kana pasi, nepo saizi yetumapundu tune huwandu hwe0.02 kusvika 0.3 microns. Vhairasi idiki kwazvo, haina njodzi here?
Ipfungwa isiriyo yakajairika yekuti chifukidzo isimbi yekusefa, kuti zvidimbu zvidiki pane buri rekusefa zvinogona kupfuura nepakati pacho, uye kuti zvidimbu zvakakura kupfuura buri rekusefa zvakavharika. Kutaura zvazviri, huwandu hunoshanda hwemasiki eN95 huri pakati pezvidimbu zvikuru nezvidiki.
Kunyangwe chifukidziro chekurapa chine dziviriro yepamusoro chiine dziviriro iri nani, chine dziviriro yakakura yekufema nekuda kwehuwandu hwezvinhu zvinosefa, kuoma kwayo, uye kupfeka kwenguva refu kunowedzera mutoro wekufema uye kukonzera matambudziko ekufema nezvimwe kusagadzikana.
Kana ichishandiswa zuva nezuva chete uye usingaendi kunzvimbo dzine njodzi huru yekutapukirwa nehutachiona, senge muzvipatara, unogona kusarudza mask yekuvhiya.
Pamusoro pekusarudza mask yakakodzera, unofanirawo kushandisa yakakodzera, uye teerera nzira yekupfeka uye nguva yekushandisa. Verenga nokungwarira nzira iri papakeji, uye simbisa kuti mhepo yakamira sei mushure mekupfeka. Kana ukapfeka magirazi uye mhute inoonekwa pa lenzi, inofanira kunge iri nekuda kwekutichifukidzohaisi kupfeka zvakanaka.
