Amanqaku
1) yonke idatha yobugcisa echazwe apha ngasentla yeyokubhekisela kuwe.
2) iinkcukacha ezizezinye zamkelekile ukuba zixoxwe ngakumbi.
Ukuphatha
Ukuphathwa kwenziwa kwindawo enomoya ococekileyo. Nxiba izixhobo zokuzikhusela ezifanelekileyo. Kuthintele ukusasazeka kothuli. Hlamba izandla nobuso kakuhle emva kokuphathwa.
Amanyathelo okuzikhusela xa uphatha izinto ngendlela ekhuselekileyo. Kuphephe ukudibana nolusu namehlo. Kuphephe ukukhupha uthuli kunye nee-aerosols. Nika umoya ofanelekileyo wokukhupha umoya kwiindawo apho uthuli lwenzeka khona.
Indawo yokugcina izinto
Gcina kwindawo epholileyo. Gcina isitya sivaliwe kakuhle kwindawo eyomileyo nengena umoya kakuhle. Ubushushu obucetyiswayo bokugcina bube yi-2 - 8 °C
Ulwazi ngezothutho
Ayilawulwa njengezinto eziyingozi.
