Oil Tank Explosion in Goyang Draws Attention Once Again to Lax Safety in South Korea

I am glad someone else noticed what I pointed out in regards to lax safety at the oil storage facility that blew up recently in Goyang:

The recent explosion of an oil tank in Goyang, Gyeonggi Province ― and the ensuing fire that consumed 2.6 million liters of gasoline over 17 hours ― has revealed the lack of adequate safety regulations at oil storage sites in the country.

The explosion on Sunday was caused by a sky lantern released by a young Sri Lankan migrant worker, about 300 meters from the oil storage site, police said.

The grass around the storage compound caught fire as the sky lantern, lifted by a burning flame inside, landed there, CCTV footage showed.

As there were no fire detectors installed outside the oil tank, the operators were unaware of the danger until the explosion came 18 minutes later, the police revealed in a briefing Tuesday.

Police suspect the explosion occurred as fire sparks from the grass made contact with oil and natural gas vapors emitted from the tank’s ventilation hatch.  [Korea Times]

You can read more at the link, but it seems it should take much more then a fire lantern to blow up a huge oil tank like this.  I try to look at this from the perspective of a North Korean saboteur.  If a sky lantern can do this much damage imagine what a coordinated North Korean sabotage attempt against the nations oil storage infrastructure could do?
