Ukuphatha kunye noGcino

1. Izilumkiso zokuphatha ngokukhuselekileyo

Kuphephe ukudibana nolusu namehlo. Kuphephe ukuphefumla umphunga okanye inkungu.

Gcina kude kwimithombo yokutshisa - Akukho kutshaya.Thatha amanyathelo okuthintela ukwakhiwa kwe-electrostatic

intlawulo.

2. Iimeko zokugcina ngokukhuselekileyo, kuquka nakuphi na ukungahambelani

Gcina kwindawo epholileyo. Gcina isikhongozeli sivalwe ngokuqinileyo kwindawo eyomileyo nengena umoya. Izikhongozeli eziivuliwe kufuneka iphinde ivalwe ngononophelo kwaye igcinwe nkqo ukuthintela ukuvuza.

Intsalela eyomileyo iyaqhuma. Gcina phantsi kwegesi engasebenziyo. Uvavanya ukwakheka kweperoxide ngamaxesha athile nangaphambiliukuchithwa.

Iklasi yokugcina (TRGS 510): Ulwelo olunokutsha

Amanyathelo okukhululwa ngengozi

1. Izilumkiso zomntu, izixhobo zokukhusela kunye neenkqubo zongxamiseko

Sebenzisa izixhobo zokuzikhusela. Kuphephe ukuphefumla umphunga, inkungu okanye igesi. Qinisekisa ukungena komoya okwaneleyo.

Susa yonke imithombo yokutshisa. Khusela abasebenzi kwiindawo ezikhuselekileyo. Lumkela umphunga oqokelelana kuwoyenza izigxina eziqhumayo. Imiphunga ingaqokelelana kwiindawo eziphantsi.

2. Izilumkiso zokusingqongileyo

Thintela ukuvuza okungaphezulu okanye ukuchitheka ukuba kukhuselekile ukwenza njalo. Musa ukuvumela imveliso ingene kwimisele.

3. Iindlela kunye nezixhobo zokuthintela kunye nokucoca

Gcina ukuchitheka, kwaye emva koko uqokelele ngesicoci sevacuum esikhuselwe ngombane okanye ngokubrasha emanzi kwayezibeke kwisingxobo ukuze zilahlwe ngokwemigaqo yendawo
