Korean natural gas powered bus explodes

Ya' think?

There used to be LP cars and buses in at least France, but not so much any more.  I think one of them took out a parking garage at some time in history.

Horseshit! I lived there for a year and didn't get to see a single bus explosion!

(I also never took a bus... )

Must have been a hyosung.

I am curios what safety standards apply to those buses in  Korea.  If heat caused the explosion and this has happened in the past they need to revisit those standards.

From the story.

"Anxiety turned to anger towards the government after the Ministry of Knowledge Economy admitted that it had found a number of defects in several buses during safety inspections made earlier this year. A total of 201 CNG buses out of the 4,300 that were tested had faults in their fuel tanks, 134 of which were deemed dangerous enough to cause an explosion.

This was the eighth time that a CNG bus has exploded in Seoul since 2005, no deaths have occurred as a result of the incidents."

" no deaths have occurred as a result of the incidents."

Did hear that the woman who had both her feet severed were reattached

LPG and CNG are two different beasts

LPG and CNG are two different beasts

With different regulations (at least in the US).  Before retirement I was certified as an installer and trainer in both.  

This is a typical CNG tank used in the US.



My guess is the tank in the bus was not even close.

[GAAN]

a CNG tank here with US specs would need to take a hell of a blow to cause a rupture like that

LPG wouldn't do that with a mere tank rupture

it would vent but not as violently

it would make some sound, suffocate some folks, run away a diesel truck or two but it wouldn't blow up a bus and tear off limbs

much safer to rupture LPG than CNG

at least until until it found an ignition source

article says more than 5 have exploded in the past several years. problem?

Happens everywhere with varying degrees of consequences. Things are found to be wrong and corners are cut to save costs. Saw it happen first hand with some shitty rebar a company was producing. The stuff met strength standards but had shit ductility which wasn't regulated. 1 out of 5 square ties you tried to make by hand would break. They refused to admit anything was wrong since they met all the standards but we ran tests on random samples from a few of their lots and all came up equally shitty. Our school has never bought rebar from them since.
