Shenhai Explosion-Ubungqina
Kwiimeko zoshishino, ngakumbi kwiindawo ezinobungozi, ukulawula iindlela ezibanzi okanye ezintsonkothileyo zeentambo ziba yinkxalabo ebalulekileyo. Xa ubude boyilo lwentambo yobungqina bokudubula bufikelela kwinqanaba elithile, okanye xa imidibaniso isahlukana ngenxa yokujika nokujijeka okuninzi, Iinkqubo zombhobho zemveli zinokubonakala zingonelanga. Kulapho ibhokisi yesiphambuka sobungqina bokudubula iba yimfuneko.
Ibhokisi yokuhlangana isebenza njenge hub ebalulekileyo embindini wentambo yokubaleka, ukuququzelela iinguqu ezigudileyo kunye nolawulo olusebenzayo lwentambo. Umsebenzi wayo ophambili kukuqinisekisa uqhagamshelo olukhuselekileyo nolukhuselekileyo apho iindlela zekhebula zithe zanda kumgama omde okanye zahlulwa zibe ziindlela ezahlukeneyo.. Ukusetyenziswa kwe ibhokisi yesiphambuka enobungqina bokudubula kwiimeko ezinjalo ayenzi lula kuphela inkqubo yokufaka iikheyibhuli kodwa ikwaxhasa imigangatho yokhuseleko efunekayo kwindawo eziqhumayo., ukuqinisekisa ukuthembeka kwenkqubo yombane kugcinwa ngamaxesha onke.
