Ukuqhuma okulimazayo, okuvame kakhulu ukubizwa ngokuthi yi-sandbever, kungukusebenza okuphoqelela ngenkani umfudlana wezinto ezibonakalayo ekubhekaneni nengaphansi kwengcindezi ephezulu ukuze kubushelelezi umhlaba onolaka, ukushwabana komhlabathi obushelelezi, ukwakheka komhlaba noma ukususa izinto ezingcolisayo. Kusetshenziswa uketshezi olucindezelwe, umoya ocindezelwe kaningi, noma isondo elingumfutho ukucindezela izinto eziqhumayo (ezivame ukubizwa ngokuthi abezindaba). Kunokuhlukahluka okuningana kwenqubo, kusetshenziswa imidiya ehlukahlukene; ezinye ziyanuka kakhulu, kanti ezinye zithambile. Okuhlukumeza kakhulu ukudubula (ngokudutshulwa kwensimbi) kanye nesihlabathi esingapheli (ngesihlabathi). Ukwehluka okuyisidlakudla kufaka phakathi ukuqhuma kwengilazi eyenziwe ngengilazi (kanye nobuhlalu bengilazi) kanye nokuqhuma kwemithombo yezindaba ngamasheya epulasitiki angaphansi noma amagobolondo e-walnut kanye nama-corncobs. Uhlobo olumnene luse-sodabaphakade (nge-baking soda). Ngaphezu kwalokho, kunezinye izindlela ezingahambi kahle noma ezingekho emafini, njengokuqhuma kweqhwa nokuqhuma okwenziwe ngeqhwa.
Isidingo esandayo semishini yokuqhuma kwesihlabathi senza imakethe ithengiswe. Ukuthuthuka kwezobuchwepheshe, izifo zamaphaphu ezinjenge-silicosis ezibangelwa ukusebenza kwebhande lokuqhuma kwesihlabathi kanye nezimboni ezisheshayo zingumshini obalulekile wemakethe yokuqhumisa isihlabathi. Ukufakwa esikhundleni komsebenzi wezandla kuthuthukisa umkhiqizo kanye nokusebenza kahle. Ukuphefumula kwe-silica, ebikade isetshenziswa ngokwesiko njengempahla ethe xaxa emishinini yokuqhuma kwesihlabathi, kubangela izingozi zezempilo ezinjenge-silicosis nezinye izifo zamaphaphu. Imishini yokuqhuma kwesihlabathi ivimbela ukungenwa noma yikuphi ukuphazamiseka kwamaphaphu, okulindeleke ukuthi kugqugquzele ukukhula kwemakethe. Imishini yase-Asia Pacific ene-sandbamele ibusa imakethe ngenxa yezindleko eziphansi kanye nesidingo esikhulu sale mikhiqizo. IChina ibikezelwa ukuthi ingumnikeli omkhulu wehola ku-APAC. Ubungako bemakethe yesantibamele yemishini kulindeleke ukuthi inyuke ngesikhathi sokubikezela, bese ilandelwa yiNyakatho Melika.
