Shenhai Explosion-Ubungqina
Iibhokisi zesiphambuka ezinobungqina bokudubula ziyilwe kwiintlobo ezimbini eziphambili zokukhusela: Irhasi ingaqhushumba kwaye ingaqhushumba.
Ukukhusela igesi-ubungqina bokuqhuma, umgangatho wesizwe ekuthotyelwe kuwo ngulo GB3836. Lo mgangatho uchaza indlela kunye nezikhokelo eziyimfuneko zokuqinisekisa ukhuseleko kwindawo apho iirhasi eziqhumayo zinokubakho., ukuqinisekisa ukuba iibhokisi ezidityanisiweyo zinokusebenza ngokukhuselekileyo ngaphandle kokulayita nayiphi na imeko enokuba yingozi.
Kwimeko yokukhusela uthuli-ubungqina bokuqhuma, umgangatho wesizwe ofanelekileyo ngu GB12476. Lo mgangatho uchaza iimfuno zokusebenza ngokukhuselekileyo kwiindawo apho uthuli oluvuthayo inokuqokelela. Iqinisekisa ukuba iibhokisi zesiphambuka ziyakwazi ukuthintela nawuphi na umthombo wokutshisa ukuba ungadibani nothuli oluvuthayo., ngokwenza njalo kugcinwe ukhuseleko kwindawo ezinjalo.
