Shenhai Explosion-Ubungqina
Xa amanqanaba e-methane edlula umda wokudubula ongaphezulu okanye esihla ngaphantsi komda osezantsi, Ukutsha kuthambile ngenxa yokunqongophala kwemethane okanye ioksijini. Ngaphakathi kogqabhuko-dubulo, nangona kunjalo, umlinganiselo we-methane-to-oksijeni ulungele ukutsha, kubangela umlilo ovuthayo.
Ukuba ngalo mzuzu, ukusabela kweekhemikhali kwenzeka kwindawo ethintelweyo kwaye ifuna ukukhutshwa okukhulu kobushushu, iigesi ezibangelwayo zanda ngokukhawuleza, iphelele kugqabhuko-dubulo.
