Ukukhetha esona sixhobo sokuphefumla semaski esinesiqingatha sobuso asikokufumana imveliso enye esebenza kuwo wonke umsebenzi. Ukhetho olufanelekileyo luxhomekeke kwingozi yomoya, indawo yokusebenza, ukhuseleko olufunekayo ixesha elingakanani, nokuba kukho iigesi, umphunga, uthuli, inkungu, okanye umsi.
Kwiingozi zamasuntswana okukhanya, a Ukulahla i-maspirator yemaski inokuba lukhetho olusebenzayo. Ngomsebenzi ophindaphindiweyo wemizi-mveliso okanye ukuvezwa kwimiphunga yeekhemikhali, i-elastomeric half-face respirator enokuphinda isetyenziswe eneekhatriji ezichanekileyo ihlala isesona sisombululo sifanelekileyo. Into ephambili kukutshatisa isiphefumlo kwingozi, kunokuba ukhethe ngokusekelwe kwinkangeleko okanye ixabiso lodwa.
Qala ngeNgcipheko yasemoyeni
Ngaphambi kokuba ukhethe isiphefumli semaski esinesiqingatha sobuso, chonga ukuba yintoni na esemoyeni. Iziphefumli zenzelwe iingozi ezithile, kwaye akukho sihluzo esinye okanye ikhatriji ekhusela kuyo yonke into.
Imizekelo eqhelekileyo ibandakanya:
- Uthuli, inkunkuma yesanti, kunye neenkungu ezingezizo ioyile: I-particle-filtering respirator inokufaneleka xa ikhethelwe umsebenzi.
- Umsi wokuwelda kunye nokwenza isinyithi: Le misebenzi inokubandakanya iincinci ezincinci kunye nezinye izinto ezingcolileyo, ngoko ke ukhuseleko kufuneka lukhethwe emva kovavanyo olufanelekileyo lokuvezwa.
- Ipeyinti, izinyibilikisi, kunye nezinto ezincamathelayo: Ezi zinokukhupha umphunga ophilayo ofuna isiphefumlo esiphinda sisetyenziswe kunye neekhatriji zomphunga ezivunyiweyo.
- Ukwenziwa kwemichiza: Iigesi ze-Acid, i-ammonia, kunye nezinye iikhemikhali zifuna iikhatriji ezivunyiweyo ngokukodwa kwezo ngozi.
Ngokutsho kweCDC/NIOSH isikhokelo ekukhethweni kokuphefumula, iziphefumlo kufuneka zikhethwe ngokusekelwe kwingozi yendawo yokusebenza kwaye zisetyenziswe njengenxalenye yenkqubo yokukhusela ukuphefumula okubanzi.
Ukulahlwa kweHalf Mask Respirator vs. Ukusebenziseka kwakhona kweHalf Face Respirator
A Ukulahla i-maspirator yemaski, edla ngokubizwa ngokuba sisixhobo sokuphefumla sobuso bokucoca, iyilelwe ikakhulu ukuhluza amasuntswana omoya afana nothuli, inkungu, kunye nomsi. Ilula, ilula ukuyisebenzisa, kwaye ikhethwa ngokuqhelekileyo kumsebenzi wexesha elifutshane apho kufuneka ukhuseleko lwamasuntswana.
Nangona kunjalo, izinto zokucoca ezilahlwayo azikhuseli kwiigesi okanye umphunga ngaphandle kokuba umenzi utsho ngenye indlela. I-NIOSH ichaza ukuba iziphefumlo zokucoca ubuso zenzelwe iingozi zamasuntswana, hayi irhasi okanye ukhuseleko lomphunga.
Ukuphinda kusetyenziswe i-elastomeric half-face respirators zenziwe ngezinto ezihlala ixesha elide kwaye zisebenzisa izihluzi okanye iikhatriji ezinokuthathelwa indawo. Zihlala zifaneleka ngcono ukusetyenziswa rhoqo, ukupeyinta ukutshiza, umsebenzi wokulondoloza, kunye nemisebenzi ebandakanya umphunga okanye ukubonakaliswa kothuli okuphindaphindiweyo. I-cartridge kufuneka ihlale ihambelana nokungcola okuchongiweyo.
Sesiphi esona sixhobo sokuphefumla sobuso esisisiqingatha seMisebenzi eyahlukeneyo?
Olona khetho lulungileyo lutshintsha ngomsebenzi:
| Umsebenzi woMsebenzi | Umkhombandlela ofanelekileyo wokuphefumla |
|---|---|
| I-Sanding wood, i-drywall, okanye ikhonkrithi | I-NIOSH-evunywe yi-particulate respirator ekhethiweyo kwinqanaba lothuli |
| Ukucoca ulwakhiwo lwesiqhelo | I-Disposable Half Mask Respirator kwiingozi ezisebenzayo zamasuntswana |
| Tshaza ipeyinti okanye umsebenzi wokunyibilikisa | Ukuphinda kusetyenziswe isiphefumli esinesiqingatha sobuso kunye neekhatriji zomphunga ezivunyiweyo |
| Ukugaya isinyithi okanye ukusika | Izihluzi zesuntswana ezikhethelwe ukuvezwa kunye nendawo yokusebenza |
| Ukuvezwa kweekhemikhali okungaziwayo | Yima ufune uvavanyo lwengozi yobuchule phambi kokuba ukhethe iPPE |
Kwimisebenzi emininzi ebandakanya uthuli oluqhelekileyo, isixhobo sokuphefumla esifakwe ngokufanelekileyo, esivunyiweyo esilahlwayo sinokuba lula. Ukuvezwa rhoqo kwipeyinti, i-solvents, okanye i-industrial contaminants, i-half-facepiece ephinda isetyenziswe inokubonelela ngokhuseleko oluhambelanayo lwexesha elide xa idityaniswe neekhatriji ezichanekileyo kunye neenkqubo zokulondoloza.
Iimpawu eziphambili ekufuneka uzijonge
Xa uvavanya isiphefumlo esinesiqingatha sobuso, gxila kwezi zinto zisebenzayo:
1. Ukhuseleko oluqinisekisiweyo
Khetha ukhuseleko lokuphefumla oluvunyiweyo kwimarike yakho kunye nobungozi obucetyiweyo. EUnited States, khangela iimveliso ezivunyiweyo ze-NIOSH kwaye uqinisekise ukuba ulwamkelo luhambelana nesihluzo okanye uqwalaselo lwekhatriji esetyenziswayo.
2. Izihluzi ezihambelana neengozi okanye iiCartridges
Isihluzo se-particle asifani nekhatriji yomphunga ophilayo. Umlinganiselo we-particle ye-N95-style, umzekelo, akufanele uphathwe njengokhuseleko kumsi wepeyinti okanye umphunga we-solvent.
3. Khusela isitywina soBuso
Isixhobo sokuphefumla sinokusebenza kakuhle kuphela xa sivala kakuhle empumlweni nasemlonyeni. Izikhewu ezibangelwa kukungalingani kakuhle, uhlengahlengiso olungachanekanga lomtya, okanye iinwele zobuso zinganciphisa ukhuseleko kakhulu.
4. Ukuthuthuzela Ubude boMsebenzi
Kwimisebenzi emifutshane, iDisposable Half Mask Respirator inokuba lula ukuyinxiba kunye nokutshintsha. Kwiinguqu ezinde, iimodeli ezinokuphinda zisebenziseke zinokubonelela ngolungelelwaniso olungcono, amacandelo anokutshintshwa, kunye nenkcitho ephantsi eqhubekayo.
5. IShedyuli yoTshintsho lweCartridge
Iziphefumli eziphinda zisetyenziswe zifuna ishedyuli ebhaliweyo yokutshintshwa. Iikhatriji kufuneka zitshintshwe ngokusekelwe kwimiyalelo yomenzi, ingozi, ugxininiso, ixesha lomsebenzi, kunye neenkqubo zokukhusela ukuphefumla kwindawo yokusebenza.
Faka iMiba kaninzi njengoKhetho lwesihluzi
Kwaneyona ndawo yokuphefumla ikumgangatho ongcono ayinakuzisa ukhuseleko olucetywayo ngaphandle kokungena ngokufanelekileyo. Kwiindawo zokusebenza apho kufuneka iziphefumli, abaqeshi kufuneka babonelele ngovavanyo olufanelekileyo, uqeqesho, ukuhlolwa, ukugcinwa kunye nokugcinwa phantsi kwenkqubo efanelekileyo yokukhusela ukuphefumla.
Abasebenzisi kufuneka bahlole itywina ngalo lonke ixesha befaka isiphefumli esiqinileyo kwaye balandele imiyalelo yomenzi. Isixhobo sokuphefumla esinesiqingatha sobuso sivala impumlo nomlomo, kodwa asiwakhuseli amehlo. Xa umsebenzi ubandakanya ukutshiza, umphunga, okanye amasuntswana abhabhayo, ukhuseleko lwamehlo olufanelekileyo nobuso lunokuba yimfuneko.
Xa iMask yobuso besiqingatha asanelanga
Isiphefumlo sokucoca umoya esinesiqingatha sobuso akufuneki sithathwe sifanelekile kwindawo yonke. Isenokungafanelekanga i-oxygen-deficit atmospheres, i-concentrations engaziwayo yongcoliseko, impendulo engxamisekileyo, izithuba ezivaliweyo, okanye amanqanaba aphezulu kakhulu okuvezwa.
Kwezi meko, ingcali yokhuseleko eqeqeshiweyo kufuneka ihlole umsebenzi phambi kokuba nabani na angene kwindawo. Ukhuseleko lokuphefumla ngumaleko omnye wolawulo kwaye akufuneki kuthathe indawo yokuphuma komoya, isithintelo, iindlela zokusebenza ezikhuselekileyo, okanye ezinye izilawuli zobunjineli.
Iingcinga zokugqibela
I-respirator engcono kakhulu ye-half-face mask yinto ehambelana nobungozi bokwenene, ihambelana nomntu oyinxibileyo ngokuchanekileyo, kwaye isetyenziswe ngokwemiyalelo yomenzi kunye nemithetho yokhuseleko esebenzayo.
A Ukulahla i-maspirator yemaski inokuba lukhetho olusebenzayo kuthuli oluthile, inkungu, kunye nezicelo zomsi. Kumsebenzi oqhubekayo obandakanya umphunga, izinyibilikisi, okanye iimeko zemizi-mveliso ezifuna ngamandla, isiphefumlo esiphinda sisetyenziswe elastomeric esinesiqingatha sobuso esineekhatriji ezichanekileyo ezivunyiweyo sidla ngokuba lolona khetho lungcono lwexesha elide. Soloko ukhetha ukhuseleko lokuphefumla olusekwe kuvavanyo lwengozi, hayi nje isimbo semaski.
