Uyikhetha njani imaski yeFFP2|KENJOY

Kukho iintlobo ezininziIimaski zeFFP2kunye nezixhobo ezahlukeneyo.Ke sikhetha njani iimaski zeFFP2 ngamaxesha aqhelekileyo?Makhe siphume kunye neumthengisi wemaskiukuqonda.

Imigangatho eyahlukeneyo ihambelana nokusetyenziswa okuhlukeneyo

1. Iimaski zotyando zokuhlukaniswa kwe-droplet (ezihambelana nenqanaba-1 lokukhusela kwizibhedlele).Xa uthenga, nikela ingqalelo kwigama lemveliso, ekufuneka ibe yimaski yokuhlinzwa yonyango.Okwesibini, inombolo yesatifikethi sobhaliso sezixhobo zonyango kufuneka iprintwe kwiphakheji yangaphandle.Okwesithathu, umgangatho wokuphunyezwa kwemveliso kwiphakheji yangaphandle kufuneka uhambelane neYY0469.

2. Umlomo okhuselayo wonyango wokwahlula umoya (ohambelana nokukhuselwa kwesibini kwizibhedlele).Xa kuthengwa ingqalelo, jonga kwipakethe yangaphandle, izixhobo zonyango kufuneka ziprintwe kwinombolo yesatifikethi sobhaliso, okwesibini kukuhlangabezana nomgangatho we-GB19083.

I-3.GB19082 iimfuno ezisisiseko zeemaski ezikhuselayo zonyango akufanele zibe nevalve yokukhupha umoya, ngoko musa ukuqwalasela iimaski ngevalve yokukhupha umoya, ungathengi, kungekhona i-anti-virus.

I-4 GB2626 le index yesiqhelo isezantsi kune-GB19083, ngokuqhelekileyo inokuthintela inkungu, ukhuseleko lwezonyango aluthengi.

5. I-N95 ibhekiswa ngokubanzi njengegama eliqhelekileyo, elimele inqanaba lokhuseleko.Enyanisweni, ukukhuselwa kwamashishini kunye nokukhuselwa kwezonyango kunezinga le-N95.Ayizizo zonke i-N95 ezichasene nentsholongwane.Ngoku amashishini amaninzi aloba kumanzi anenkathazo, evuthela ukhuseleko lwemizi-mvelisoIimaski ze-N95kwi-anti-virus.

Ngenxa yokukhethwa komlomo udidekile ngakumbi, apha ukukwazisa emlonyeni wamanqaku amaninzi ahlukeneyo

Abalindelekileyo.Imodeli kunye nomgangatho wemaski ziprintwa kwicala lasekhohlo lemaski.Unokukhetha imaski ngokwale nto.

Iimaski zohlulwe zibe ziikhrayitheriya ezintathu:

I-N95 yenziwe kumgangatho we-NOISH waseMelika.

I-FFP2 ngumgangatho waseYurophu we-EN149;

I-KN95 ngumgangatho waseTshayina we-GB2626-2006.

Zonke iimaski eziphawulwe ngale migangatho mithathu zizimaski ezifanelekileyo.

iimaski ze-N95 zonyango kufuneka zithintele ukutshiza kolwelo olunoxinzelelo oluphezulu, ke ngoko zinemigangatho ephezulu kune-N95 eqhelekileyo;Ukuthatha i-3M njengomzekelo, iimodeli ze-1860 kunye ne-9132 zizona zixhobo zomlomo ezikhuselayo zonyango.

Kwaye ke kukho i-1860s yabantwana.Abantu abaqhelekileyo okanye abasebenzi bezonyango abangavezwanga kuxinzelelo oluphezulu lwe-spatter yolwelo bangakhetha ukusebenzisa umgangatho oqhelekileyo we-N95 NIOSH.

Umgangatho waseTshayina we-GB2626-2006 ubhekisa kumgangatho oqhelekileyo womlomo we-KN95

Umgangatho weemaski ze-KN95 zokusetyenziswa kwezonyango yi-GB19083-2010.

Ngokufanayo, abantu abaqhelekileyo kunye nabasebenzi bezonyango abangaqhagamshelani nokuchitheka kolwelo olunoxinzelelo oluphezulu banokusebenzisa iimaski eziqhelekileyo ze-KN95.Nangona kunjalo, phantsi kobhubhane, kukho imingcipheko ethile.Inombolo yebhetshi yezixhobo zonyango ezinokuthengwa yiyona nto ingcono.

Omnye umbuzo oqhelekileyo yivalve yokukhetha imaski okanye imaski ngaphandle kwevalve?Iimaski eziqhelekileyo ezineevalve zikhululekile ngakumbi.

Iimaski zotyando azivumelekanga ukuba zibe neevalvu

Xa abantu bosulelekile okanye berhanelwa ukuba bosulelekile, kufuneka bakhethe imaski yotyando ngaphandle kwevalve (akukho mntu waziyo ukuba omnye umntu wosulelekile okanye imeko yakhe, ngoko akukhuthazwa ukunxiba imaski enevalve kwindawo yobhubhane. ).

Iimaski zotyando lwezonyango, umgangatho oqhelekileyo yi-YY0469-2010 okanye YY0469-2011, eprintwe kwiphakheji yangaphandle ezimeleyo yemaski nganye.

Nantso indlela yokukhetha imaski.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeFFP2, nceda uqhagamshelane nathiabavelisi bemaski.
