Kupanda kuwongolera uinjiniya komanso chitetezo chogwira ntchito, masks a ffp2 amatha kuletsa ogwira ntchito tsiku ndi tsiku ku zoopsa za moyo ndi thanzi.Masks a ffp2 akapanda kupereka chitetezo chokwanira kwa ogwiritsa ntchito, chiwopsezo chokumana ndi zoopsa zopumirazi chimawonjezeka ndikubweretsa zotsatira zoyipa zaumoyo.Chifukwa chake, ndikofunikira kuwonetsetsa kuti masks a ffp2 amapereka chitetezo chokwanira kwa ogwiritsa ntchito.

Mayeso a kusefera bwino

Masks a Ffp2 amasankhidwa ngati zopumira zoyeretsa mpweya ndipo amagwiritsidwa ntchito kwambiri ndikuvomerezedwa ndi ogwira ntchito m'mafakitale osiyanasiyana komanso anthu wamba.Izi ndichifukwa choti ffp2 imapezeka mumitundu yosiyanasiyana, yoyenera mawonekedwe osiyanasiyana a nkhope, yosavuta kusamalira, ilibe chopinga chochepa kwa wovala, ndipo imakhala ndi mayeso apamwamba kwambiri potengera kulemera ndi kuphweka.Ogwira ntchito yazaumoyo amalangizidwa kuti agwiritse ntchito masks ovomerezeka a ffp2 kapena zopumira zapamwamba kuti athe kuthana ndi matenda osiyanasiyana opatsirana ndi mpweya.

Masks a FFP2 sangathe kugwiritsidwa ntchito m'malo otsitsa mafuta;R (kukana mafuta pang'ono) ndi P (kukana kwamphamvu kwamafuta) kumatanthauza kuti chopumiracho chingagwiritsidwe ntchito kuteteza ku aerosols omwe si amafuta ndi mafuta.Mayina a manambala 95, 99 ndi 100 akuwonetsa kuti kusefa kocheperako kwa fyuluta ndi 95%, 99% ndi 99.97%, motsatana.

Kuteteza kwa mpweya wopumira pa tizilombo toyambitsa matenda kumatha kuyesedwa bwino pophunzira momwe zimatetezera kupuma kwa tinthu tating'ono topatsirana tofanana ndi kukula kwa tinthu tapakhungu.Chifukwa chake, tinthu tating'onoting'ono ta sodium chloride (NaCl) ndi dioctyl phthalate (DOP) zimagwiritsidwa ntchito ngati ma aerosols ovuta kuyesa momwe zimatetezera zopumira.Tinthu tating'onoting'ono ta NaCl timagwiritsidwa ntchito poyesa kusefera kwa ma aerosol omwe siamafuta, pomwe tinthu tating'onoting'ono ta DOP timayesa kuyesa ma aerosols amafuta.

Pamene tinthu tating'onoting'ono timalowa mu chopumira kudzera kutayikira kwa chisindikizo cha nkhope ndi zosefera, ntchito yopumira imawunikidwa ndi mayeso olimbitsa thupi, kuyesa kolowera komanso kuyesa kwathunthu kwamkati kwa anthu.Nthawi zambiri amagwiritsidwa ntchito kuwerengera kuyenera kwa masks a ffp2.Cholinga cha mayesowa ndikuwunika kuchuluka kwa chitetezo chomwe chimapezedwa ndi chopumira poganizira zopereka zanjira zonse zotuluka.Sikokwanira kugwiritsa ntchito kuyezetsa thupi kapena kusefa kuti muwunikire magwiridwe antchito onse a chopumira.Mayesero a chitetezo cha kupuma nthawi zambiri amagwiritsidwa ntchito pogwiritsa ntchito mutu wa mannequin m'malo mwa anthu, kunyalanyaza zinthu zaumunthu monga kukula kwa nkhope ndi kupuma komanso kuthamanga komwe kungasokoneze chitetezo choperekedwa ndi chopumira.

Zomwe zili pamwambapa ndikuyambitsa kuyesa kusefa kwa ffp2 masks.Ngati mukufuna kudziwa zambiri za masks a ffp2, chonde omasuka kulankhula nafe.
