Ungayikhetha kanjani imaski ye-PM2.5? Amadolobha anamuhla agcwele umusi, futhi ikhwalithi yomoya iyakhathaza. Sixoxa ngokuthi izifihla-buso zibhekisa kwizifihla-buso zokuzivikela eziklanyelwe i-PM2.5, kuyilapho izifihla-buso zomphakathi ezijwayelekile zisetshenziselwa ukuvimbela umkhuhlane. Izinsizakusebenza nokucaciswa kwazo akunazidingo ezihlanganisiwe, kepha empeleni, akunamthelela ku-PM2.5 nasekuvikeleni izifo.
Igama lesiShayina le-PM2.5 liyizinhlayiyana ezinhle. I-particle enhle isho izinhlayiya ezinobubanzi obulinganayo be-aerodynamic obungaphansi noma obulinganiselwa kuma-microns ayi-2,5 emoyeni oqondile. Ngenxa yokuthi izinhlayiya zincane kakhulu, imaski ejwayelekile njengamaski kakotini kunzima ukusebenza. Mayelana nokuthenga izifihla-buso ze-PM2.5, ukucaciswa kukhuphuka, ukuthi izinga lokuvikela liba ngcono kangakanani, ukumelana nokuphefumula okujwayelekile, nokubi kakhulu lapho ukugqoka. Uma ugqoka imikhiqizo yale ncazelo isikhathi eside, kungavela ngisho ne-hypoxia enamandla.
Futhi lapho ukuma kwe-PM2.5 mask kungalingani ebusweni, izinto eziyingozi ezisemoyeni zizongena emgudwini wokuphefumula zivela endaweni lapho zingalingani khona, noma ngabe ukhetha imaski enesihlungi esihle kakhulu. Ayikwazi ukuvikela impilo yakho. Ngakho-ke manje imithetho eminingi nezindinganiso zakwamanye amazwe zichaza ukuthi abasebenzi kufanele bavivinye njalo ukulunga kwamaski, ukuze kuqinisekiswe ukuthi abasebenzi bakhetha usayizi ofanele wamaski futhi bagqoke amaski ngokwezinyathelo ezifanele, ngakho-ke amaski kufanele ahlukaniswe ngosayizi abahlukahlukene ukubhekana nawo amaqembu ahlukene abantu.
Ngaphezu kwalokho, izimaski zekhabhoni ezisebenzayo zithandwa kakhulu njengamanje. Lolu hlobo lwamamaski lungavimba ngempumelelo iphunga ngenxa yokwengezwa kwekhabhoni esebenzayo ngenkathi kucatshangelwa ukusebenza kahle kokuvikela uthuli. Uma ukhetha lo mkhiqizo, kufanele ubone ngokucacile ukusebenza kwawo ngokuqasha uthuli, hhayi nje ukudideka yicarbon.
Kunconywa ukuthi ugqoke umshini wokuphefumula we-PM2.5 nge-valve yokuphefumula ngangokunokwenzeka, ukuze unciphise ukushisa okumanzi okubangelwa ukugqoka umshini wokuphefumula isikhathi eside. Ngasikhathi sinye, ilula iba ngcono.
