Izincazelo
Ukusebenza kokuhlunga– isihlungi siyahlolwa ukuze kulinganiswe ukuncipha kokugxila kwama-aerosols athile emoyeni adlula esihlungini.
I-ejenti yokuhlola- i-aerosol ekhiqizwa ngesikhathi sokuhlolwa kokusebenza kwesihlungi.
Ukuvuza okuphelele kwangaphakathi (TIL)- inani le-aerosol ethile elingena endaweni yobuso ye-respirator ehloliwe ngokungena kokubili kwesihlungi kanye nokuvuza kwe-faceseal, kuyilapho ogqokile enza uchungechunge lokuvivinya umzimba ekamelweni lokuhlola.
Ukuvuza kwangaphakathi (IL)- inani le-aerosol ethile engena endaweni ehloliwe yokuphefumula, kuyilapho ogqokile enza ukuphefumula okuvamile imizuzu engu-3 ekamelweni lokuhlola.Usayizi we-aerosol wokuhlola (ukubala kobubanzi obumaphakathi) cishe u-0.5 micro mitha.
Ukwehla kwengcindezi- umoya wokumelana ungaphansi lapho uhamba phakathi nendawo, njengesihlungi sokuphefumula.
Ngokusekelwe kuthebula elingenhla, kunengqondo ukucabangela i-China KN95, i-AS/NZ P2, i-Korea 1st Class, ne-Japan DS FFRs “njengelingana” ne-US NIOSH N95 kanye neziphefumulo zokuphefumula zase-European FFP2, ngokuhlunga izinhlayiya ezingasekelwe kuwoyela njengalezo eziwumphumela. kusuka emlilweni wequbula, PM 2.5 ukungcoliswa komoya, ukuqhuma kwentaba-mlilo, noma ama-bioaerosols (isb. amagciwane).Kodwa-ke, ngaphambi kokukhetha umshini wokuphefumula, abasebenzisi kufanele bathintane nemithetho nezimfuneko zendawo zokuvikela ukuphefumula noma bahlole iziphathimandla zezempilo zomphakathi zendawo ukuze bathole isiqondiso sokukhetha.
