Intsingiselo yeBakala ye-FFp2 imaski |KENJOY

Ii-aerosols kunye namasuntswana amahle zezona ngozi zimbini ziyingozi kakhulu kwimpilo kwindawo yokusebenza, kodwa amehlo ethu ahlala kunzima ukuwabona.Okulandelayo, makhe sijonge ukuba njaniffp2 iimaskiumsebenzi.

Ukubaluleka kokhuseleko lokuphefumla

Amasuntswana ayingozi anokubangela umhlaza okanye abe ne-radioactive;omnye umonakalo kwinkqubo yokuphefumla.Ukuqhagamshelana kwamashumi eminyaka kunokukhokelela ekuphuhliseni izifo ezinzulu.Okona kulungileyo, bonke abasebenzi bajongana nevumba elibi.Imaski yokucoca ibonelela ngeentlobo ezintathu zokhuseleko kwi-aerosols enamafutha aphuma emanzini, umsi kunye namasuntswana amahle ngexesha lomsebenzi.Umsebenzi wayo wokukhusela uhambelana nomgangatho we-European Union EN 149. Ezi maski, ezaziwa ngokuba ziimaski zesihluzi sesiqingatha sesuntswana okanye iimaski zesuntswana ezintle, zihlelwa njengeFFP1, FFP2 kunye neFFP3 amabakala okhuseleko.

Isebenza njani imaski yeFFp2?

Imaski yokucoca amasuntswana inokuthintela ngempumelelo uthuli, inkungu kunye nomsi.Ilaphu elishinyeneyo lokucoca elilukiweyo lithintela ukudlula kwezinto eziqinileyo, kwaye umaleko ongaphakathi we-electrostatic ukuqinisekisa ukuba izinto eziyingozi zincanyathiselwe kuwo kwaye aziyi kuphefumlelwa.Inkqubo yohlelo iqulathe iiklasi ezintathu ze-FFP, kwaye isishunqulelo esithi FFP simela "isigqubuthelo semaski".Imaski yokuphefumla igquma umlomo kunye neempumlo kwaye yenziwe ngezinto ezahlukeneyo zokucoca kunye nemaski ngokwayo.Kufuneka zisetyenziswe kwindawo yokusebenza engaphezulu komda wokuvezwa emsebenzini (OEL).Olu lolona gxininiso luphezulu lothuli, umsi kunye / okanye i-aerosols esiyiphefumla emoyeni kwaye ayenzakalisi impilo yethu.Ukuba kukho nakuphi na ukuphulwa, kufuneka unxibe imaski yegesi.

Yintoni enokuthintela iimaski zeFFp2?

Ngokuxhomekeke ekuvuzeni okupheleleyo kunye nokuhluzwa kwamaqhekeza ukuya kwi-0.6 μ m, iimaski ze-FFP2 zokuphefumla zibonelela ngokhuseleko lokuphefumla kungcoliseko lwazo zonke izigxina.Ukuvuza okupheleleyo kusekelwe ekungeneni kwesihluzi kunye nokuvuza kwindawo yomlomo kunye neempumlo.Enkosi kubuchwephesha obutsha bokucoca, ukuxhathisa ukuphefumla kunokugcinwa kuncinci, kwaye amasuntswana abambekayo kwisihluzo awayi kukwenza mandundu ukuphefumla emva kokunxitywa amaxesha amaninzi.

Imaski ye-FFP2 yokukhusela i-respirator ifanelekile kwiindawo zokusebenza apho iinqununu ezinobungozi kunye ne-mutagenic ziqulethwe kumoya wokuphefumula.Iimaski ezinjalo zokuphefumula kufuneka ziqulathe ubuncinane i-94% yobuninzi bee-particles ze-0.6 μ m kwaye zingasetyenziselwa kwiindawo eziphula i-OEL kunye noxinzelelo oluphezulu lwamaxesha e-10.Kuyafana nakwixabiso le-TRK (i-technical reference concentration).Iimaski zokuphefumla zomgangatho we-FFP2 zihlala zinxitywa kumashishini esinyithi kunye nemigodi.Abasebenzi kula mashishini bahlala bechanabeke kwi-aerosols, inkungu kunye nomsi, nto leyo enokukhokelela kwizifo zokuphefumla, ezinjengomhlaza wemiphunga.Okubaluleke kakhulu, basengozini enkulu yesifo sesibini kunye nesifo sofuba esisebenzayo.

Oku kungasentla sisingeniso kwi-ffp2 imaski.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeffp2, nceda uzive ukhululekile ukuqhagamshelana nathi.
