Izinga laseYurophu lamamaski yi-FFP. Liyini izinga laloImaski ye-FFP2?Kuzohlala isikhathi esingakanani?Manje, ake sazi kabanzi ngakho.
Ngingayisebenzisa isikhathi esingakanani imaski ye-ffp2
Imaski ye-Ffp2, enye ye-European mask standard EN 149:2001, elahlwayo (ngokuvamile amahora angu-2-4), ukusebenza kahle kokuhlunga okuncane kungaphezu kuka-94% futhi kungavimba ama-aerosols ayingozi ngaphandle kokuphefumula.
Izinga le-FFP2 lisekelwe esimisweni sokunamathela ngogesi nge-Bai. Lingahlunga ngempumelelo uthuli nezinhlayiya ezinamafutha emoyeni we-THE ZHI. Ukusebenza kahle kokuhlunga kungaphezu kwama-94%. Isiqeshana sekhala singagotshwa ukuqinisekisa ukulingana okuhle phakathi kwemaski nobuso kanye nokuphefumula okubushelelezi; Nge-valve yomphumela wokumunca wonke, umphumela wokuvikela uzoba ngcono kakhulu kunokungabikho kwe-valve, ngokuvamile akukho sihlungi sokunikeza izinhlayiya ze-valve cishe ku-90%, kanti i-valve ingaphezu kwama-65%.
Kuyaqondakala ukuthi izinga lemaski liphakeme kune-FFP1 (umphumela wokuhlunga omncane > 80%), kodwa liphansi kune-FFP3 (umphumela wokuhlunga omncane > 97%).
Amamaski avamile e-FFP2 angasetshenziswa kabusha
Amamaski e-FFP2, enye ye-European mask standard EN149:2001, amunca ama-aerosols ayingozi, okuhlanganisa uthuli, intuthu, amaconsi enkungu, amagesi anobuthi kanye nomhwamuko ngokusebenzisa izinto zokuhlunga, futhi avimbele ukuthi abantu bangawaphefumuli. Umphumela wokuhlunga omncane we-FFP2 kanye ne-GT;94%. Sivame ukubona amamaski e-FFP2 alahlwayo. Lena iyalahlwayo. Kukhona namamaski ayingxenye kanye nama-hood agcwele, womabili angasetshenziswa izikhathi eziningi ngokushintsha isici sokuhlunga.
Kwenzekani uma imaski ye-FFP2 isusiwe
Ingqimba yangaphandle yamaski ohlobo lwe-FFP2 ivame ukugcwala ukungcola namagciwane emoyeni wangaphandle, kuyilapho ungqimba lwangaphakathi luvimba amabhaktheriya akhipha umoya kanye namathe. Ngakho-ke, izinhlangothi zombili akufanele zisetshenziswe ngokushintshana, ngaphandle kwalokho ungqimba lwangaphandle olungcolile luzohogela emzimbeni womuntu uma lunamathela ngqo ebusweni futhi lube umthombo wokutheleleka. Uma ungagqokile imaski, yigoqe ibe yimvilophu ehlanzekile bese ugoqa ubuso eduze kwekhala lakho nomlomo. Ungayifaki ephaketheni lakho noma uyilengise entanyeni yakho.
Amamaski e-FFP2 afana namamaski e-N95 kanye ne-KN95 futhi awakwazi ukuhlanzwa. Ngenxa yokuthi ukumanzisa kuzobangela ukukhishwa kukagesi ongaguquki wemaski, ayikwazi ukumunca uthuli olunobubanzi obungaphansi kuka-5um. Ukuhlanza ngomusi oshisayo kufana nokuhlanza ngoba kukhipha nogesi ongaguquki, okwenza amamaski angasebenzi.
Uma unezibani ze-ultraviolet ekhaya, ungacabanga ukusebenzisa izibani ze-ultraviolet ukuhlanza ubuso bemaski, ukuze uvimbele ukuthintana ngengozi nobuso bemaski nokungcola. Izinga lokushisa eliphezulu lingabulala amagciwane, kodwa imaski ivame ukwenziwa ngezinto ezifanayo. Izinga lokushisa eliphezulu lingabangela ukuthi imaski ishise futhi ibangele izingozi zokuphepha. Akukhuthazwa ukusebenzisa i-oven noma ezinye izindawo zokuhlanza amagciwane okushisa okuphezulu.
