In a house in Soi Phetkasem 77/8, Nong Khaem District, Bangkok, the scene of the incident was a two-story townhouse. The scene of the incident was next to the door of the house.

The tank that exploded was thrown 100 meters away and hit the houses of nearby people, damaging 3-4 houses and some were scattered around the houses. From the preliminary investigation, it was l earned that before the incident, the deceased was carrying an oxygen tank into a pickup truck parked near the scene of the incident. to bring to the factory in Samut Sakhon area But during the transport of the tank There was a violent explosion. By the force of compressing the body of the deceased Until he was thrown out of the house before dying. While Mr. Chaiwat Business owner and owner The house after the incident gave information that a private business owner collected oxygen tanks from industrial plants. by oxygen tank came to stay at the said house To prepare for adding oxygen from the factory Before taking these tanks Sent to another industrial factory without assembly or addition of oxygen tanks in any way. As for the cause of the explosion It is a time when workers Loading empty oxygen tanks into a pickup truck. to add oxygen But it is not known how the explosion occurred, which is usually difficult. It is assumed that the tank that exploded may have had oxygen left inside. However, this must wait for verification from the police at Nong Khaem Police Station and the Forensics Division officials. to find the cause of another explosion The girlfriend of the deceased Travel to the scene When he arrived, he cried a lot. Because I was sad and couldn't accept the incident. and asked the officer to look at his boyfriend's body When the reporter went in to ask for information about whether or not he had talked to the deceased this morning. She said they didn't talk. My boyfriend has been doing this job for 10 years and she once said that this job was dangerous. But he's been doing it for a long time. And the protective equipment that boyfriends sometimes wear, sometimes they don't. But he admits that his girlfriend is a smoker. While Miss Thananya, a witness to the incident and heard the sound of an explosion Said he heard an explosion. loudly and it felt like some debris had hit the roof of the house So she ran out to look and saw a lot of smoke rising, but at that time she still didn't see the deceased or the injured. So she hurriedly called 191, admitting that the incident had happened, she was very shocked because her house and the neighborhood had only elderly people and said that there had previously been a fire incident in the same alley 2-3 years ago. Like Mr. Nithi, a neighbor who was behind the scene said I have known the owner for a long time. Ready to tell the story that he heard the sound of a car coming to a stop. which will come like this every day But today, after only 5 minutes of parking, I heard a loud explosion, so I quickly ran out of the house because I knew that It was the sound of a gas explosion. When I ran out to look, I saw smoke. And dust spread all over the area, but we still haven't seen any dead or injured people. Ready to admit feeling worried Because the house in question had stored gas tanks for more than 10 years, the tanks were quite old. and was afraid that one day there would be a gas explosion If the bomb were to explode, his house would be destroyed as well. This event is considered Luckily only one tank exploded. If several tanks were exploded at the same time, there might be more losses. As for his house, there was some damage to the wall next to the house where the incident happened. The door glass was damaged. The Nong Khaem District Director revealed that Inspect the scene Initially, 37 oxygen tanks, 16 carbon dioxide tanks, and 18 acetylene gas tanks were found, totaling 71 tanks, which operators said were empty tanks received from industrial plants. Brought to storage to prepare for packaging chemicals. and sent back to industrial plants The chemical tank that exploded Initially it was said to be a tank containing acetylene gas. It is a chemical used for welding metal in the industrial sector. Preliminary examination of the scene of the incident did not reveal that permission had been properly requested to store chemicals. The district office must collect evidence and coordinate with the investigating officer. and prove evidence Prepare to prosecute the business owner. and ordered the area of ??the incident to be closed immediately designated as a dangerous area Accelerate coordination with business owners to introduce risky chemicals. such as acetylene gas tanks Leave the area today As for the cause of the explosion, we still have to wait for proof from the Police Forensics Division as to what caused it. Mr. Chum Sonsayan, head of Bang Khae Fire Station, revealed that the explosion If there is gas remaining in the tank If it is not used completely, if it is moved or dropped, it may cause it to explode. As for the case where the tank may deteriorate and cause an explosion, Normally, the factory that packs it must inspect the tank. If it's damaged, it won't be packed. One more doubt That is, acetylene tanks are flammable. There is a possibility If there is a spark from the cigarette lighter while there was a gas leak Or the worker tried to open the valve to vent gas from the tank. The conclusion still has to wait for the person who proves the evidence to verify it more clea rly. Acharn Aod suspects there was a gas explosion. Caused by an acetylene gas tank Assoc. Prof. Dr. Veerachai Puttawong, an academic in the field of organic chemistry and Assistant Rector for Innovation and Social Enterprise Kasetsart University or A. Aod gave information on the case of the oxygen tank explosion that from pictures of the scene it is known that Found a green oxygen tank. It will feature a CGA540 valve tank, ISO9809-3 standard, thick steel, stamped without seams, pressure 1500-2000 PSI, packing size 10L - 40L, packing volume 0.5m3 - 6m3. The red tank contains acetylene gas. which has relatively high pressure and is a flammable gas In the industrial sector, they are often used together. And from the body of the deceased there was gray-black soot. Probably caused by ignition. or an ignition reaction occurs It is therefore believed to be caused by acetylene gas, size 40 liters, which has a relatively high pressure of 1500-2000 PSI. If the old tank is rusty and has been dropped and hit, It will cause the metal tank to tear. An explosion can occur, so it is considered a warning to entrepreneurs. You must be careful when checking the condition of the oxygen tank, and those working in this field must use caution when transporting it. And filling oxygen gas to 2000 PSI should use a new tank with ISO, TIS standards Source: Thai News Agency
