Inxalenye yokuhluza imaski yesiqingatha (6002-2 FFP2)

6002-2 EN149 FFP2 ivavanywa phantsi kwe-EN 149: 2001 + A: 2009 Izixhobo zokukhusela zokuphefumla-Ukucoca imaski yesiqingatha ukukhusela kumasuntswana

Ukuhambelana nolusu
Izinto ezinokuthi zidibane nolusu lomntu ozinxibileyo aziyi kwaziwa ukuba zinokubangela ukucaphuka okanye nayiphi na enye impembelelo embi empilweni.(Pasiwe)

Ukutsha
Xa ivavanywa, isiqingatha semaski esihluza imaski asiyi kutshisa okanye singaqhubeki sitshisa ngaphezulu kwemizuzwana emi-5 emva kokususwa edangatyeni.(Pasiwe)

Umxholo wekharbhon diokside kumoya wokuphefumla
Umxholo we-carbon dioxide womoya wokuphefumla (indawo efileyo) awuyi kudlula umyinge we-1.0% (umthamo).(Upasisiwe).

Intsimi yombono
Inkalo yombono iyamkeleka ukuba kumiselwe njalo kwiimvavanyo zokwenziwa komsebenzi.(Pasiwe)

Ukumelana nokuphefumla

(Igqithiselwe) Ukupakishwa Olu lwazi lulandelayo luya kuphawulwa ngokucacileyo kwaye ngokusisigxina kweyona ipakethe incinci ekhoyo kurhwebo okanye ifundeke ngayo ukuba isingxobo siselubala.1.Igama, uphawu lwentengiso okanye ezinye iindlela zokuchongwa komenzi okanye umboneleli 2.Uhlobo-ukuchonga uphawu 3.Uhlelo Udidi olufanelekileyo (FFP1, FFP2 okanye FFP3) lulandelwa sisithuba esinye kunye ne'NR' ukuba isiqingatha sokucoca amasuntswana imaski inqandelwe ukusetyenziswa kweshifti enye kuphela.Umzekelo: FFP2 NR.4.Inani kunye nonyaka wokupapashwa kwalo Mgangatho waseYurophu 5. Ubuncinci unyaka wokuphela kobomi beshelufu.6. Iimeko ezicetyiswayo zomenzi zokugcina (ubuncinci ubushushu kunye nokufuma)

Imaski yokucoca isiqingatha sesuntswana ingqiniwe ukuba ibonelela ngokhuseleko olungcono kumathontsi, ii-aerosols kunye nokungena kolwelo kunye nokwenza itywina eliqinileyo emlonyeni nasempumlweni.

Iimaski zonyango/zotyando zibonelela ngomqobo okhawulezileyo phakathi kwamalungu okuphefumla kunye nokusingqongileyo.Ukusebenza kwe-mask yobuso okanye i-respirator kugqitywa zizinto ezimbini ezibalulekileyo, ukucocwa kakuhle kunye nokufaneleka (ukuvuza kobuso).Ukusebenza kohluzo lulinganisa ukuba imaski ihluza kakuhle kangakanani amasuntswana kuluhlu lobungakanani obuthile, obubandakanya iintsholongwane kunye namanye amasuntswana e-submicron, ngelixa ukulingana kulinganisa ukuba imaski okanye isiphefumlo sikuthintela njani ukuvuza okujikeleze ubuso.Ngokusekwe kwimigangatho yoLawulo lokuTya kunye neZiyobisi (i-FDA) kunye nempumelelo yokucoca, iimaski zonyango zinokuhlelwa ngokweendidi ezahlukeneyo.Ezi zahlulwe kwinqanaba le-ASTM 1, 2 kunye ne-3 ngokusekelwe kwimpumelelo yokumelana nolwelo.Inqanaba lesi-3 linika eyona ntsholongwane iphezulu yokuhluza intsholongwane ngokuxhathisa okuphezulu ekungeneni kolwelo lomzimba.EYurophu, iimaski zonyango zithobela iimfuno zoMgangatho waseYurophu EN 14683:2019.

Nangona kunjalo, iimaski zotyando azisebenzi kangako xa zithelekiswa neziphefumla.Izixhobo zokuphefumula ziquka izixhobo zokukhusela eziqinileyo okanye izicoci zomoya ezinokuthintela amaqhekeza amancinci (<5 μm) ukuba adlule kwindlela yokuphefumula yomntu.Oku kuphunyezwa mhlawumbi ngokususa izinto ezingcolisayo okanye ngokubonelela ngomthombo ozimeleyo womoya wokuphefumla.Bathiywa ngokwahlukileyo kumazwe ahlukeneyo.E-USA, iNational Institute for Occupational Safety and Health (NIOSH), imisela ukusebenza kakuhle kohluzo lwezi ziphefumlo kwaye zihlelwa ngokwe-N-, R-, kunye nochungechunge lwe-P ngenxa yokunganyangeki kwe-oyile, ngandlel ithile ukumelana ne-oli kunye nokuxhathisa ngamandla. , ngokulandelelanayo.Uluhlu ngalunye lwezintathu luneendlela ezintathu ezihlukeneyo zokuhluza kwii-95, 99 kunye ne-99.97%, ezizezi, i-N95, i-R95, i-P95, njl. EYurophu, iindidi ze-respirators zingahlelwa njengokucoca imaski yesiqingatha (iziqwenga zobuso bokucoca (FFP)), iimaski zesiqingatha, i-air-purifying respirator (PAPR) kunye ne-SAR (i-atmosphere-supplying respirator).Ngokwemigangatho yaseYurophu, i-FFPs iphinda ihlulwe kwi-FFP1, i-FFP2 kunye ne-FFP3, kunye nokusebenza kakuhle kwe-80%, i-94% kunye ne-99%, ngokulandelanayo (EN 149: 2001).
