Yeyiphi imigangatho yovavanyo eyongezelelweyo efunekayo emva kokuveliswa kwemaski

Umgca wemveliso weemaski ulula kakhulu, kodwa into ebalulekileyo kukuba ukuqinisekiswa komgangatho weemaski kufuneka kujongwe umaleko ngomqolo.
Imaski iya kuveliswa ngokukhawuleza kumgca wokuvelisa, kodwa ukuze kuqinisekiswe umgangatho, kukho iinkqubo ezininzi zokuhlola umgangatho. Umzekelo, njengemaski ekhuselayo yezonyango enenqanaba eliphezulu lokhuseleko, kufuneka ihlolwe izihlandlo ezili-12 ngaphambi kokuba ibekwe emarikeni.

Iimaski zihlelwa ngokwahlukileyo, kwaye kukho umahluko omncinci kwimigangatho yovavanyo. Iimaski zokhuselo lwezonyango zinelona nqanaba liphezulu kwaye zifuna uvavanyo oluninzi olunje ngeziqeshana zempumlo, imitya yemaski, ukusebenza kakuhle kokucoca, ukuchasana nokuhamba komoya, ukungena kwegazi elenziweyo, ukuxhathisa ukufuma komphezulu, kunye nezalathi zemicrobial. Kumvavanyi wokusebenza kwe-flame retardant kwiimaski, abasebenzi babeka imaski kwi-mold yentloko kwaye baqalisa umatshini ukuba uvuthe. Umngundo wentloko onxibe imaski unqumla idangatye elinobude obuziimilimitha ezingama-40 kunye nelangatye lobushushu langaphandle elimalunga nama-800 degrees Celsius ngesantya seemilimitha ezingama-60 ngomzuzwana, nto leyo ebangela ukuba umphandle wemaski ugoqeke kancinci ngenxa yokutsha.

Iimaski zotyando olufanelekileyo kunye neemaski ezikhuselayo kufuneka zibe neempawu zokunqanda amadangatye, kwaye phantsi kweemeko zebhubhoratri ezichaziweyo, ixesha lokutshisa eliqhubekayo lelaphu emva kokususa ilangatye akufanele lidlule imizuzwana emi-5. Iimaski ezingafanelekanga zinokuvelisa ilangatye elikhulu kwiimeko ezinzima, kwaye ixesha lokucima lingadlula imizuzwana emi-5. Imaski iyakwenza uvavanyo lokungena kwegazi, ilinganisa indawo yegazi elitshiza kwimaski ngezixhobo zokuhlola. Imveliso efanelekayo yileyo, emva kokugqiba olu vavanyo, ingenalo igazi elingena kumphezulu ongaphakathi wesigqubuthelo sobuso.

Ukuqina kokuqina kwemaski, komelele ngakumbi umphumo wayo wokukhusela, ngoko ke uvavanyo lokuqina luyinxalenye ebalulekileyo yokuhlolwa komgangatho wemaski. Intatheli yabona ukuba olu vavanyo lufuna ukukhetha iimilo zentloko ezi-10 ezahlukeneyo zamadoda ama-5 kunye nabasetyhini aba-5 kuvavanyo lokuqina. Abasebenzi abavavanyiweyo kufuneka balinganise iintshukumo zabasebenzi bezonyango ngexesha lomsebenzi, kwaye baqokelele idatha kwiindawo ezahlukeneyo ezifana nokuphefumla okuqhelekileyo, ukujika kwentloko ekhohlo nasekunene ukuphefumla, kunye nokunyuka kwentloko ukujika ukuphefumla. Kuphela emva kokuba abantu abasi-8 bahlangabezane nemigangatho abanokuthi ukuxinwa kwale batch yeemveliso kumiselwe ukuhlangabezana neemfuno.

Ngokwemigangatho yelizwe, ezinye izinto zokuhlola zineemfuno ezingqongqo zexesha. Umzekelo, uvavanyo lomda we-microbial luthatha iintsuku ezisi-7, kwaye uvavanyo lokucocwa kwebhaktiriya luthatha iiyure ezingama-48 ukuvelisa iziphumo.
Ukongeza kwiimaski ezikhuselayo zonyango kunye neemaski ezikhuselayo zemihla ngemihla, sikwadibana neemaski zokhuselo ezilahlwayo, iimaski ezinithiweyo, iphepha lemaski kunye nezinye iimveliso kubomi bethu bemihla ngemihla. Ukongeza, kukho olunye uhlobo olubizwa ngokuba yi-self-priming filter type anti particle mask, eyathi kamva yatshintshwa yaba yi-self-priming filter type anti particle respirator ukuze ichaze umgangatho wesizwe ngokuchanekileyo.
