Yiziphi izinzuzo zamaski we-N95
I-N95 iyindinganiso yokuqala ephakanyiswe yiNational Institute of Occupational Safety and Health (NIOSH).“N” isho ukuthi “akuzifanelekeli izinhlayiya ezinamafutha” futhi “95″ isho umgoqo ezinhlayiyeni ezincane ezingu-0.3 ngaphansi kwezimo zokuhlola ezishiwo kuzinga le-NIOSH.Izinga kufanele libe ngaphezu kwama-95%.
Ngakho-ke, i-N95 akulona igama elithile lomkhiqizo, kodwa kufanele libe yindinganiso.Inqobo nje uma i-NIOSH ibuyekeza futhi isebenzisa le maski ejwayelekile, ingabizwa ngokuthi “N95″.
Amamaski e-N95 ngokuvamile anedivayisi yokuphefumula efana nomlomo wengulube, ngakho-ke i-N95 ibuye ibizwe ngokuthi “imaski yengulube”.Ekuhlolweni kokuvikela kwezinhlayiya ezingaphansi kwe-PM2.5, ukudluliswa kwe-N95 kungaphansi kuka-0.5%, okusho ukuthi ngaphezu kwe-99% yezinhlayiya zivinjelwe.
Ngakho-ke, imaski ye-N95 ingasetshenziselwa ukuvikela ukuphefumula emsebenzini, okuhlanganisa nokuvimbela izinhlayiya ezithile ezincane (ezifana namagciwane amagciwane abumba isifo sofuba i-Bacillus anthracis), i-N95 ngokungangabazeki iyisihlungi esihle, umphumela wokuvikela kumaski avamile.
Kodwa-ke, yize umphumela wokuvikela we-N95 uphezulu ekuvikelweni komaski abajwayelekile, kusenemikhawulo ethile yokusebenza, okwenza imaski ye-N95 ingafanele wonke umuntu, futhi akusona isivikelo esingenangqondo.
Okokuqala nje, i-N95 ayinamandla okuphefumula nokunethezeka, futhi inokumelana nokuphefumula okukhulu lapho igqokwa.Akufanelekile kubantu asebekhulile abanezifo ezingapheli zokuphefumula kanye nokuhluleka kwenhliziyo isikhathi eside ukugwema ubunzima bokuphefumula.
Okwesibili, lapho ugqoke imaskhi ye-N95, kufanele unake ukubopha isiqeshana sekhala futhi uqinise umhlathi.Imaski nobuso kufanele kulingane eduze ukuze kuvinjwe izinhlayiya ezisemoyeni ukuthi zingamuncwa ngegebe eliphakathi kwemaski nobuso, kodwa ngenxa yokuthi ubuso bomuntu ngamunye buhluke kakhulu, uma imaski ingaklanyelwe ukulingana ubuso bomsebenzisi. , kungase kubangele ukuvuza.
Ngaphezu kwalokho, imaski ye-N95 ayikwazi ukugezeka, futhi isikhathi sabo sokusebenzisa amahora angama-40 noma inyanga eyi-1, ngakho-ke izindleko ziphezulu kakhulu kunamanye amamaski.Ngakho-ke, abathengi abakwazi ukuthenga i-N95 ngokungaboni ngoba inokuvikelwa okuhle.Lapho uthenga imaski engu-N95, kufanele kucatshangelwe ngokugcwele inhloso yokuvikela kanye nezimo ezikhethekile zomsebenzisi.
