Umahluko phakathi kwe-FFP2 imaski kunye nemaski yotyando|KENJOY

Yintoni umahluko phakathi kwe-aFFP2 imaskikunye nemaski yotyando?Ziziphi iimpawu phakathi kwezi zibini?Lo mxholo ulandelayo unokukunika ukuqonda ngcono umahluko phakathi kweemaski ezimbini.Ndiyathemba ukuba iya kuba luncedo kuwe emva kokuyifunda.

Izinto eziluncedo kunye nezingeloncedo zokuzikhusela

Iimaski zeFFP2 zinokukhusela ngcono amasuntswana ayingozi, kodwa abantu abaninzi bayaqhubeka nokukhetha iimaski zotyando.Uphawu lwemaski yotyando lwezonyango kukuba ikhusela abanye ekuphefumleni komntu oyinxibileyo, kodwa imaski yeFFP2 ikhusela lowo uyinxibileyo kunye nabanye macala omabini.

Ngaba utyando lwezonyango lwanele?

Njengoko iintsholongwane ziqhubeka zenza umonakalo emoyeni, iimaski zotyando zisasebenza, kwaye ukunxiba nayiphi imaski kungcono kunokungayinxibi kwaphela.Nangona kunjalo, ngamaxesha eentsholongwane ezosulelayo, sifuna iimaski ze-FFP2 kuba iimaski zonyango azisaneli ukujongana nentsholongwane esasazekayo, esasazeka emoyeni ngokukhawuleza kunayo nayiphi na intsholongwane eyaziwayo.

Indawo evalelweyo-ekhethwayo yiFFP2 imaski

Abavelisi be-FFP2 bacebisa ukuba bahlale besebenzisa iimaski ze-FFP2 kwiindawo ezivaliweyo.Ukongeza, xa abantu befuna ukudibana nabantu abasemngciphekweni, kufuneka bakhethe iimaski zeFFP2.

Nangona umkhwa utshintshile, baya besanda abantu abanxiba iimaski zeFFP2 kwiindawo zikawonke-wonke, kodwa abanye abantu bayaqhubeka nokukhetha iimaski zotyando.Iingcali zithi kwelinye icala, yingxaki yexabiso, kwaye esinye isizathu yintuthuzelo.Ukuba inxitywe ngokuchanekileyo, inokubangela ukungakhululeki kweendlebe ixesha elide kwaye ishiye namanqaku ebusweni.

Imaski yotyando lwezonyango

Umahluko phakathi kwemaski yotyando lwezonyango kunye ne-ffp2 imaski yeyokuba inqanaba lokhuseleko lemaski yotyando lonyango linqanaba elinye elisezantsi, kwaye imaski yotyando lwezonyango ihlangabezana neemfuno zobugcisa zemaski yotyando lwezonyango.Ngaphantsi kwemeko yokuhamba komoya (30 ± 2) L / min, ukusebenza kakuhle kokucoca kwe-aerodynamic median diameter (0.24 ± 0.06) μ m i-sodium chloride aerosol ayikho ngaphantsi kwe-30%.Ukuphumelela kokuhluzwa kweebhaktheriya phantsi kweemeko ezichaziweyo, ukusebenza kakuhle kokucoca kwe-aerosol ye-Staphylococcus aureus kunye ne-avareji ye-particle diameter ye (3 ±0.3) μ m ayikho ngaphantsi kwe-95%.Ngaphantsi kwemeko yokusebenza kakuhle kokucoca kunye nesantya sokuhamba, ukuchasana kokuphefumula akudluli i-49Pa kwaye ukuchasana nokuphelelwa yisikhathi akudluli i-29.4Pa.

Iimaski zotyando zibonakaliswa kwizalathisi zobugcisa, ngakumbi ukuba isiphumo sesithintelo se-0.3 ye-micron engeyo-oyile efunwa ziimaski zotyando lungaphezulu kwe-30%, iimaski zokhuselo lwezonyango ezifana ne-ffp2 imaski ziyi-95%, kunye nesithintelo sebhaktheriya se-2 microns. Ububanzi budinga ukuba bukhulu kune-95%, oko kukuthi, umgangatho we-BFE95, ongaphantsi kancinane kwiimaski ze-ffp2, kodwa ungabi mbi kakhulu.

Impembelelo yokukhusela iyona nto ibhetele xa igqoke ngokuchanekileyo

Abavelisi be-FFp2 bagxininise ukubaluleka kokunxiba okuchanekileyo.Ukuba kukho umsantsa phakathi kwempumlo kunye nezihlathi, okanye ukuba unxibe imaski efanayo iintsuku ezininzi zilandelelana, imaski ililize, nokuba unxibe iFFP2.Iimaski zeFFP2 azikhuseli ukuba azitywinwanga kakuhle ebusweni, kungenjalo intsholongwane isenako ukungena okanye iphume, yiyo loo nto abantu benokosuleleka nangona benxibe imaski.

Lo ngumahluko phakathi kweemaski zeFFP2 kunye neemaski zotyando.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeffp2, nceda uzive ukhululekile ukuqhagamshelana nathi.
