At about 20:40 on June 21, 2023, during the peak period of Zhengyi dinner, the liquefied petroleum gas (liquefied gas tank) leakage in the operation room of Fuyang barbecue shop, Minzu South Street, Xingqing District, Yinchuan City, caused an explosion, causing 38 casualties, of which 31 people died after ineffective rescue, and 7 people were under full treatment (1 critically ill, 2 moderate burns, 2 mild injuries, and 2 glass scratches).

Saddened, very saddened. In an instant, 31 living lives were swallowed up. They clearly still have such a bright future. It can be seen how serious the consequences of the explosion caused by the leakage of liquefied gas are. Once the operation is improper, it will cause huge losses to people's lives and property.

But we can't give up eating because of choking. At present, liquefied gas is still our indispensable energy, and it has brought great convenience to the masses. As long as we regulate the use, do not operate dangerously, and install liquefied gas leak alarms, find problems in time, and find professionals to repair and solve problems, it is still very safe.

First of all, we need to briefly understand the liquefied gas, the main component of liquefied gas is propane, butane, etc., very easy to spontaneous combustion, when its content in the air reached a certainConcentrationAfter the scope is encounteredopen flamecan explode. The lower explosive limit of propane and butane is close to about 20000ppm, below which open fire will not explode. Therefore, if the leak can be found during this period, the accident will not occur after the timely treatment. So how do we find out?

1. Generally, liquefied gas for civil use will be added with ethanethiol and other gases with rotten egg smell. People will smell it immediately when it leaks.

2. Install liquefied gas leak alarm or use liquefied gas leak detector.

At the same time, it is also necessary to keep the place where the liquefied gas is installed ventilated, and the liquefied gas cannot explode and burn without reaching a certain concentration in the space. Check the pipeline regularly. Whether the valve is aging or damaged to cause leakage.

Generally speaking, liquefied gas is used in places such as kitchens or bathrooms. No one will be in these places all the time, so it may not be possible to smell the smell in time to find the leak. If you smell the peculiar smell farther away, the leakage may be very large, so large that it will explode when you encounter high heat or open flame, which is very dangerous. Therefore, it is better to install an alarm or use a detector to be more reliable and safe. After all, the alarm is generally sound and light alarm, and some also have networking functions, at any time to send the situation to the mobile phone. The detector is more convenient for patrol inspection and easy to check where the leakage occurs, such as pipeline interface, hose aging and other positions, and regular inspection is carried out to prevent problems before they occur.

The core device of the alarm and detector is the sensor used to detect the leakage of liquefied gas. Here to recommend you a sensor TGS2618-D00, this sensor is Japan Figaro specifically for the detection of liquefied gas research and development.

TGS2618-D00 are ideal for liquefied gas leak detection, such:

1, TGS2618-D00 anti-interference ability is very strong, no response to the kitchen cooking wine or gas fume components, to avoid false positives

2. The TGS2618-D00 responds quickly to combustible gas. (GB 15322 requires T90 response time within 30 seconds)

3. TGS2618-D00 repeatability is very good.

4. Long-term stability.

In addition, the performance of the TGS2618-D00 in terms of anti-silicon poisoning ability, anti-vibration and anti-drop are also fully in line with the requirements of GB 15322, which is very suitable for liquefied gas leak detection.

The following are the basic parameters of the TGS2618-D00:

Detection range: 500-10000ppm

Detection object: butane, LP gas

      Circuit voltage: 5.0±0.2V DC

      Heating voltage: 5.0±0.2V DC

      Heater power consumption: 280mW

Life expectancy:>5 years
