LPG Tanker Leak In Khon Kaen

Picture from responders
 

10 August at 22:38, a gas leak accident involving a tanker truck occurred on the inbound side of Mittraphap Road, between kilometers 288-289, in Nai Mueang Subdistrict, Ban Phai District, Khon Kaen Province.

 

The incident happened while the LPG gas tanker was transferring gas into a roadworkers’ tank at the side of the road. A hose connection detached, causing the gas to escape rapidly. The truck driver, along with the roadwork staff, noticed the large amount of gas escaping and fled the scene in panic, without shutting off the valve and so not preventing the gas from leaking.

 

The tanker was quickly engulfed in a highly flammable vapour cloud, which prevented anyone gaining access to the vehicle’s emergency shut off valve. Due to the fire and possible explosion risk, the road was shut in both directions, while responders used water spray hose lines, to initially control the spread of the vapour cloud and then to gain access to the shut valve and stopping the leaking LPG.

 

When the vapour cloud had been successfully disbursed, a check of the tanker found the leak had almost emptied the entire contents. An investigation into the incident will be conducted by local police.

oh dear '   we are seeing alot of gas leak emergencies in the news lately.   I find it very worrying that any tom, dick or harry connects any shop LPG tank, gas hose and fitting in this place.   

Street stalls,  restaurants, houses and everyone just connects their own hose to these death traps. 

 

I'm seriously going to convince my thai friends to convert cooking to induction and throw out the horrible gas bottle.  it may take time & persuasion but I'll get there ....   I already placed a gas detector on their wall 1 ft off the floor near the cooker.

They were trained well - what a bunch of monkeys

Couldn't agree more, that's the first thing any normal tanker driver should do.

LPG is no more dangerous than gasoline

Clearly you have little knowledge of emergency response.

LPG is transported as a liquid, so hence it is under pressure, so when a leak of LPG occurs it expands about 270 times its volume as a liquid. If you spill gasoline it will just runs over the ground, does not expand.

 

Yes both are flammable, with the flammable range of LPG being between 1.5% and 9.6% and gasoline is between 1.4% to 7.6%.

 

Gasoline is lighter than air, so the vapour will rise and disperse. LOG is heavier than air, so sinks and travel great distances before it will disperse in air. It will also flow into any low level opening, such as drains, conduits, basements, etc, so posing a possible additional fire and explosion risks.

 

The BLEVE (Boiling Liquid Expanding Vapour Explosion) risk for LPG is far greater, as LPG has a boiling point of -42°C, where as gasoline is 35 °C.

 

The ERG (emergency response guidebook) recommended evacuation distance for a tanker fire, LPG is 1600m where for gasoline it is half that at 800m.

A few facts, that shows the risk of LPG is greater than gasoline.
