Ziziphi iingenelo zeemaski ze-N95
I-N95 ngumgangatho wokuqala ocetywayo liZiko leSizwe loKhuseleko lweMisebenzi kunye neMpilo (NIOSH)."N" ithetha "ayifanelekanga i-oily particles" kwaye "95" ithetha isithintelo kwiincinci ze-0.3 ze-micron phantsi kweemeko zovavanyo ezichazwe kumgangatho we-NIOSH.Ireyithi kufuneka ibe ngaphezulu kwama-95%.
Ke ngoko, i-N95 ayilogama lemveliso ethile, kodwa kufuneka ibe ngumgangatho.Logama nje i-NIOSH iphonononga kwaye iphumeza le maski isemgangathweni, inokubizwa ngokuba yi "N95".
Iimaski ze-N95 zihlala zinesixhobo sevalve yokuphefumla esifana nomlomo wehagu, ngoko ke i-N95 ikwabizwa ngokuba “sisigqubuthelo sehagu”.Kuvavanyo lokukhusela lwamaqhekeza angaphantsi kwe-PM2.5, ukuhanjiswa kwe-N95 kungaphantsi kwe-0.5%, oku kuthetha ukuba ngaphezu kwe-99% yeengqungquthela zivaliwe.
Ke ngoko, iimaski ze-N95 zingasetyenziselwa ukhuseleko lokuphefumla emsebenzini, kubandakanya nokuthintela amasuntswana athile entsholongwane (ezifana neentsholongwane iibhaktheriya ezibumba isifo sephepha iBacillus anthracis), i-N95 ngokungathandabuzekiyo sisihluzo esilungileyo, isiphumo sokhuseleko kwiimaski eziqhelekileyo.
Nangona kunjalo, nangona isiphumo esikhuselayo se-N95 siphezulu kukhuseleko lweemaski eziqhelekileyo, kusekho imida yokusebenza, eyenza iimaski ze-N95 zingafanelanga wonke umntu, kwaye ayilokhuselo lobudenge.
Okokuqala, i-N95 ihlwempuzekile ekuphefumleni nasekuthuthuzeleni, kwaye inokumelana nokuphefumla okukhulu xa inxityiwe.Ayifanelekanga kubantu abadala abanezifo ezingapheliyo zokuphefumla kunye nokungaphumeleli kwentliziyo ixesha elide ukuphepha ubunzima bokuphefumla.
Okwesibini, xa unxibe imaski ye-N95, kufuneka ubeke ingqalelo ekubambeni ikliphu yempumlo kwaye uqinise umhlathi.Imaski kunye nobuso kufuneka zilingane ngokusondeleyo ukunqanda amasuntswana emoyeni ukuba afunxeke ngaphakathi ngomsantsa ophakathi kwemaski kunye nobuso, kodwa ngenxa yokuba ubuso bomntu ngamnye bahluke kakhulu, ukuba imaski ayenzelwanga ukulingana ubuso bomsebenzisi. , kunokubangela ukuvuza.
Ukongeza, iimaski ze-N95 azihlambeki, kwaye ixesha labo lokusebenzisa iiyure ezingama-40 okanye inyanga enye, ngoko ke iindleko ziphezulu kakhulu kunezinye iimaski.Ke ngoko, abathengi abanakuthenga i-N95 ngobumfama kuba inokhuseleko olulungileyo.Xa kuthengwa iimaski ze-N95, ingqwalasela epheleleyo kufuneka inikwe kwinjongo yokukhusela kunye neemeko ezikhethekileyo zomsebenzisi.
