Uvavanyo lobungakanani bemaski ye-FFP2 |KENJOY

Izixhobo zokukhusela ukuphefumla zihlala zisetyenziselwa ukukhusela abantu kwiingozi zokuphefumla, kubandakanywa imichiza, i-biological kunye ne-radioactive substances.Inqaku lanamhlanje lithetha ngendlelaffp2 iimaskiziyavavanywa.

Ngokungabikho kolawulo lobunjineli kunye nokhuseleko olusebenzayo, iimaski ze-ffp2 zinokuthintela abasebenzi ekusebenzeni kwemihla ngemihla kwiingozi zobomi kunye nempilo.Xa iimaski ze-ffp2 zingaboneleli ngokhuseleko olwaneleyo kubasebenzisi, umngcipheko wokuvezwa kwezi ngozi zokuphefumula uya kwanda kwaye ukhokelele kwiziphumo ezibi zempilo.Ke ngoko, kubalulekile ukuqinisekisa ukuba iimaski zeffp2 zibonelela ngokhuseleko olwaneleyo kubasebenzisi.

Uvavanyo lwempumelelo yokucoca

Iimaski ze-FFP2 zihlelwa njengezixhobo zokuphefumla zokucoca umoya kwaye zisetyenziswa kakhulu kwaye zamkelwe ngabasebenzi kumashishini ahlukeneyo kunye nabemi ngokubanzi.Oku kungenxa yokuba i-ffp2 ifumaneka kwiindidi ezahlukeneyo zobukhulu, ezifanelekileyo kwiindidi ezahlukeneyo zobuso, kulula ukuyigcina, inomqobo omncinci kulowo uyinxibileyo, kwaye inovavanyo oluphezulu malunga nobunzima kunye nokulula.Abasebenzi bezempilo bayacetyiswa ukuba basebenzise iimaski ezivunyiweyo ze-ffp2 okanye izixhobo zokuphefumla eziphezulu ukulwa nezifo ezosulelayo eziphuma emoyeni.

Iimaski ze-FFp2 azinakusetyenziswa kwindawo yethontsi yeoli;I-R (inokumelana ne-oyile ngandlela-thile) kunye ne-P (ukumelana ne-oyile eyomeleleyo) kuthetha ukuba i-respirator ingasetyenziselwa ukukhusela kwii-aerosols ezingenayo i-oyile kunye ne-oily.Amagama amanani 95, 99 kunye ne-100 abonisa ukuba ubuncinci bokuhluza ukusebenza kakuhle kwesihluzo yi-95%, 99% kunye ne-99.97%, ngokulandelanayo.

Umphumo wokukhusela wokuphefumula kwii-microorganisms unokuvavanywa ngokufanelekileyo ngokufunda umphumo wokukhusela ukuphefumula kweengqungquthela ezingenasifo ezihambelana nobukhulu beengqungquthela ezithathelwanayo.Ngoko ke, i-sodium chloride (NaCl) kunye ne-dioctyl phthalate (DOP) iinqununu zisetyenziswa ngokuqhelekileyo njengomngeni we-aerosols ukuvavanya umphumo wokukhusela we-respirators.Iinqununu ze-NaCl zisetyenziselwa ukuvavanya ukusebenza kakuhle kwe-filtration ye-aerosols engeyona i-oyile, ngelixa i-DOP particles isetyenziselwa ukuvavanya i-oily aerosols.

Njengoko amasuntswana angena kwi-respirator ngokusebenzisa ukuvuza kwesitywina sobuso kunye nezinto zokucoca, ukusebenza kwe-respirator kuhlolwa ngovavanyo lokufaneleka, uvavanyo lokungena kunye novavanyo olupheleleyo lwangaphakathi lokuvuza kwizifundo zabantu.Iqhele ukusetyenziswa ukulinganisa ukufaneleka kweemaski ze-ffp2.Injongo yovavanyo kukuvavanya inqanaba lokukhusela eliphunyezwe ngumphefumli xa kuqwalaselwa igalelo lazo zonke iindlela zokuvuza.Akwanelanga ukusebenzisa uvavanyo lokufaneleka okanye ukuhluza idatha ukuvavanya ukusebenza ngokubanzi kwesiphefumlo.Uvavanyo lokukhusela ukuphefumula luhlala lwenziwa kusetyenziswa intloko ye-mannequin kunezifundo zabantu, ukugatya izinto zomntu ezifana nobukhulu bobuso kunye neepatheni zokuphefumula kunye namazinga okuhamba angaphazamisa ukukhuselwa okuhlinzekwa ngukuphefumula.

Oku kungasentla kukungeniswa kuvavanyo lokucoca iimaski zeffp2.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeffp2, nceda uzive ukhululekile ukuqhagamshelana nathi.
