Umgangatho waseYurophu weemaski yiFFP. Lithini izinga lazoImaski yeFFP2?Iza kuhlala ixesha elingakanani? Ngoku, makhe sifunde ngakumbi ngayo.
Ndingayisebenzisa ixesha elingakanani imaski ye-ffp2
Imaski ye-Ffp2, enye ye-European mask standard EN 149:2001, elahlwayo (ngesiqhelo iiyure ezi-2-4), ubuncinci bokusebenza kakuhle kokuhluza kungaphezulu kwe-94% kwaye inokuthintela ii-aerosols eziyingozi ngaphandle kokuphefumla.
Umgangatho we-FFP2 usekelwe kumgaqo wokunamathela nge-electrostatic nge-Bai. Ingahluza ngokufanelekileyo uthuli kunye namasuntswana anamafutha emoyeni we-THE ZHI. Ukusebenza kakuhle kokuhluza kungaphezulu kwama-94%. Ikliphu yempumlo inokugotywa ukuqinisekisa ukuba ihambelana kakuhle phakathi kwemaski nobuso kunye nokuphefumla okuthambileyo; Ngevalvu yesiphumo sokufunxa iyonke, isiphumo sokukhusela siya kuba ngcono kakhulu kunokungabikho kwevalvu, ngesiqhelo akukho sihluzo sokubonelela ngamasuntswana evalvu malunga nama-90%, kunye nevalvu engaphezulu kwama-65%.
Kuyaqondakala ukuba inqanaba lemaski liphezulu kuneFFP1 (umphumo wokucoca ubuncinci > 80%), kodwa liphantsi kuneFFP3 (umphumo wokucoca ubuncinci > 97%).
Iimaski eziqhelekileyo zeFFP2 ziyalahlwa
Iimaski ze-FFP2, enye yeemaski zaseYurophu ezisemgangathweni we-EN149:2001, zifunxa ii-aerosols eziyingozi, kubandakanya uthuli, umsi, amathontsi enkungu, iigesi ezinobuthi kunye nomphunga ngokusebenzisa izinto zesihluzo, kwaye zithintela ukuba zingaphefumlelwa ngabantu. Isiphumo esincinci sokuhluza se-FFP2 kunye ne-GT;94%. Sihlala sibona iimaski ze-FFP2 ezilahlwayo. Le ilahlwayo. Kukwakho neemaski ezisisiqingatha kunye nee-hoods ezipheleleyo, zombini ezingasetyenziswa amaxesha amaninzi ngokutshintsha into yesihluzo.
Kwenzeka ntoni xa imaski yeFFP2 isusiwe
Umaleko wangaphandle weemaski zohlobo lwe-FFP2 udla ngokuzaliswa bukungcola kunye neebhaktheriya emoyeni wangaphandle, ngelixa umaleko wangaphakathi uvimba iibhaktheriya ezikhupha umoya kunye namathe. Ke ngoko, amacala omabini akufuneki asetyenziswe ngokutshintshana, kungenjalo umaleko wangaphandle ongcolisiweyo uya kuphefumlelwa emzimbeni womntu xa unamathela ngqo ebusweni kwaye ube ngumthombo wosulelo. Xa unganxibi imaski, yisonge ibe yimvulophu ecocekileyo kwaye usonge ubuso kufutshane nempumlo nomlomo wakho. Musa ukuyifaka epokothweni yakho okanye uyixhome entanyeni yakho.
Iimaski ze-FFP2 zifana neemaski ze-N95 kunye ne-KN95 kwaye azinakucocwa. Ngenxa yokuba ukumanzisa kuya kubangela ukukhululwa kombane ongashukumiyo kwimaski, ayinakufunxa uthuli olunobubanzi obungaphantsi kwe-5um. Ukubulala iintsholongwane ngomphunga obushushu obuphezulu kufana nokucoca kuba kukhupha nombane ongashukumiyo, okwenza iimaski zingasebenzi.
Ukuba unezibane ze-ultraviolet ekhaya, ungacinga ngokusebenzisa izibane ze-ultraviolet ukubulala iintsholongwane kumphezulu wemaski, ukuze kuthintelwe ukudibana ngengozi nomphezulu wemaski kunye nongcoliseko. Ubushushu obuphezulu bunokubulala iintsholongwane, kodwa imaski idla ngokwenziwa ngezinto ezifanayo. Ubushushu obuphezulu bunokubangela ukuba imaski itshise kwaye ibangele iingozi zokhuseleko. Akukhuthazwa ukusebenzisa i-oven okanye ezinye izixhobo zokubulala iintsholongwane kubushushu obuphezulu.
