Emergency services were alerted via hotline 199 on September 24, about a liquefied petroleum gas (LPG) leak in the Pruksa Village, The Seasons Romklao-Lat Krabang housing estate, located in Soi Chalong Krung 53, Chalong Krung Road, Lam Pla Thiew subdistrict, Lat Krabang district. Firefighters and rescue teams from the Lat Krabang Fire and Rescue Station were immediately dispatched to the scene.

 

 

Upon arrival at approximately 10:15, the officials began inspecting the area to assess the situation. It was confirmed that a 15-kilogram LPG cylinder had leaked, leading to an explosion. The blast had ripped wall linings off, broke windows and part of the roof had been blown away., with a stand up fan found hanging from the ceiling. Fortunately the force of the blast had vented the home, so there was no fire, with no further gas build up and responders isolated the cylinder by turning off the valve.
 

Unfortunately, the blast resulted in one person being injured, a 73-year-old woman who was in the home at the time of the incident. Paramedics from Lat Krabang Hospital promptly arrived on the scene and began administering first aid to the victim, who was found under the debris. She had suffered suspected fractures to arms and legs and was only semi conscious with a head injury. The casualty was transported to the hospital for further treatment.

 

The cause of the leak is under investigation, but this incident underscores the importance of strict safety measures and regular checks on gas cylinders to avoid potentially catastrophic outcomes.

oh dear Georgealbert,   grandma was lucky she wasn't killed.  The problem in Thailand with LPG tanks and cookers is that any tom dick or harry hooks them up and some folks won't tighten a clamp as much as the next guy.  

 

I have a friend who just installed a new SS double gas cooker and overhead fan hood.  I have told him the gas bottle must be outside,  I keep telling him every week to get a price and put the bottle outside.  Then also when any connection are done, it should be done by the gas shop professional.

I keep mine inside but keep it turned off when not used. If outside it would be kept on.

If you're lucky.

I can understand this,  but I still say outside is safer.   imo

More likely leaking from the regulator connector seal and/or delivery hose or connection to the cooking appliance and not the cylinder.

Well at least there was no fire, otherwise the tank itself could have exploded.

There was clearly no fire, as can be seen from the damage is not showing any signs of anything being burnt.
 

The unignited leaking gas in this incident, had built up to be within its explosive range, between LEL (lower explosive limit) 2.1% (Propane) 1.9% (Butane) and UEL (upper explosive limit) 9.5% (Propane) 8.5% (Butane). The mixture found an ignition source, which could have been a flame (candle, cigarette, etc) or spark (electrical switch) and ignited the leak.

 

The ignition of the leaking gas caused the explosion in the room creating a high pressure wave that did the structural damage, thus venting the area. The high pressure wave would suppress and extinguish the now burning leak and hence no fire developed as the leaking gas was no longer contained, so could not form an explosive mixture.

 

A gas explosion like this is not going to cause an LPG cylinder to exploded, as LPG is not susceptible to thermal shock, like some gases, (such as acetylene) but requires direct heating of the cylinder before a BLEVE (boiling liquid expanding vapour explosion) can occur. The possibly of a BLEVE of a cylinder, will be dependent on the temperature it is exposed to, the quality, age and condition of the cylinder and how full the cylinder is.

I explained to you why there was no fire, or do you not like having things explained to you?

 

LPG cylinder explosions are not a common occurrence, and if there was BLEVE the damage would have been far greater and a lot more extensive.

I do not need anything explained to me about LPG thanks. I simply made a comment to say it was lucky there was not a fire. but you couldn't leave it there. Please stop. I am being polite as I dare be.

Funny, as previously with the fire you questioned me on in Sattahip, you clearly have very limited knowledge of the subject.

 

I simply explained why there was no fire, and not just for your benefit.

 

Can you please tell me where any of my information was wrong?
