Iimaski eziqhelekileyo ziquka: iimaski zekotoni,iimaski ezilahlwayo(umz., iimaski zotyando, iimaski zotyando), kunye neemaski zokukhusela zonyango (iimaski ze-N95/KN95).
Phakathi kwazo, iimaski zokukhusela zonyango (iimaski ze-N95/KN95) kunye neemaski zotyando zonyango zombini ziimveliso zonyango ezilawulwa yirhulumente ukusukela kwi-SARS ngo-2003, kwaye zinomsebenzi wokuthintela ukudlula kolwelo kunye namaconsi. Ukuba zinxitywe kakuhle, zinokuthintela ngempumelelo izifo ezithwalwa ngamaconsi. Lukhetho lwethu lokuqala lwemaski.
I-N95 ayilogama lemveliso elithile. Imveliso ehlangabezana nomgangatho we-N95 kwaye ivunyiwe yi-NIOSH inokubizwa ngokuba yimaski ye-N95.
ETshayina, iimaski ze-K95 zibhekisa kuhlu lweemaski zezinto ezingezizo ioyile ngokwemigangatho yesizwe yaseTshayina i-GB2626-2006. Udidi lwe-KN lufanelekile ekuhluzeni izinto ezingezizo ioyile. Inxalenye yedijithali yala mazwe mabini inomgangatho ofanayo. I-95 ibhekisa ekusebenzeni kakuhle kokuhluza ≥95%.
Ngokwembono ye-microbiological, ukhetho olufanelekileyo yi-respirator yezonyango ehambelanayo, engaphefumliyo (i-respirator ye-N95/KN95)
Iimaski zokukhusela zonyango kufuneka zihlangabezane nomgangatho onyanzelekileyo we-GB 19083-2010 waseTshayina kunye nokusebenza kakuhle kokucoca ≥95% (kusetyenziswa uvavanyo lwezinto ezingenamafutha). Kufuneka uphumelele uvavanyo lokungena kwegazi olwenziweyo (ukuthintela ulwelo lomzimba ekutshizeni) kunye nokufikelela kwiimpawu zentsholongwane.
Iimaski zotyando zisetyenziswa kakhulu kumagumbi otyando nakwezinye iindawo apho kukho umngcipheko wokuchitheka kolwelo lomzimba kunye negazi. Zinokuthintela igazi kunye nolwelo lomzimba ukuba lungadluli kwiimaski kwaye zingcolise umntu ozinxibileyo. Okwangoku, zinokusebenza kokucoca okungaphezulu kwe-95% kwiintsholongwane.
Iintsholongwane zezona nxalenye zincinci esizifumanayo imihla ngemihla. Siqhelene ne-PM2.5, ebhekisa kwiinxalenye ezinobukhulu be-2.5 microns okanye ngaphantsi, ngelixa ubukhulu be-virus buqala kwi-0.02 ukuya kwi-0.3 microns. Le ntsholongwane incinci kakhulu, ayiyongozi na?
Yingcamango ephosakeleyo eqhelekileyo ukuba imaski sisihluzo, ukuba amasuntswana amancinci kunomngxuma wesihluzo anokudlula kuwo, kwaye amasuntswana amakhulu kunomngxuma wesihluzo avaliwe. Enyanisweni, uluhlu olusebenzayo lweemaski ze-N95 luphakathi kwamasuntswana amakhulu kunye namasuntswana amancinci.
Nangona imaski yokukhusela yezonyango enenqanaba eliphezulu lokhuseleko inefuthe elingcono lokhuseleko, inokumelana okuphezulu kokuphefumla ngenxa yenqanaba eliphezulu lezinto zokucoca, ukuqina okuhle, kunye nokunxitywa ixesha elide kuya kwandisa umthwalo wokuphefumla kwaye kubangele ubunzima bokuphefumla kunye nokunye ukungonwabi.
Ukuba isetyenziswa yonke imihla kuphela kwaye awuyi kwiindawo ezinomngcipheko omkhulu wokosulelwa zizifo, ezifana nezibhedlele, ungakhetha imaski yotyando.
Ukongeza ekukhetheni imaski efanelekileyo, kufuneka usebenzise nefanelekileyo, kwaye uqaphele indlela yokunxiba kunye nexesha lokusebenzisa. Funda ngononophelo indlela ekwiphakheji, kwaye uqinisekise ukuba umoya awungeni kakuhle emva kokunxiba. Ukuba unxiba iiglasi kwaye kuvela inkungu kwilensi, kufuneka ukuba kungenxa yokubaimaskiakanxibi kakuhle.
