Nice one OP, just as our people say "Prevention is better than cure", Stobborn flies follows the coffin to the grave" no be say na our wish for any thing bad to happen but many people suppose don hear about the consequences but dey no dey look am as anything.
I go judge from the picture wey dey attached for this post, with the way the person arrange the gas and generator together fit lead to easily explosion, make we try dey help ourselves sometimes no be everything wey happen we go use blame the innocent devil.
Normally we know how the price of fuel dey high but if u no fit afford the fuel and prefer to use the gas, why not move the gas cylinder in a far distance and use hose to connect with the generator. This would help correct the explosion.
