Tai'an Greenland Mansion first-floor doorway because of liquefied petroleum gas tank leakage triggered by the explosion, the total **** caused 13 people were injured, three of them died because of rescue efforts. The investigation of the matter has also been fully carried out, and the city's scope along the street stores to carry out investigation and rectification. The accident occurred after the local authorities and residents are more rigorous use of gas and liquefied petroleum gas, the relevant equipment has also been checked and repaired to put the accident again.
Natural gas and liquefied petroleum gas leakage explosion requires three conditions. The first gas concentration of 5% to 15% of the explosion limit; the second explosion of the space is relatively closed, and the presence of oxygen; the third need for fire. When these three conditions are fully satisfied, natural gas in a closed environment will be ignited after the rapid expansion of high-pressure gas will explode. Liquefied gas leakage is more dangerous than natural gas, the liquid outflow will rapidly expand 250 times in the air, the leakage of liquefied gas will sink to the ground, and then slowly gathered together, and will explode when it encounters an open flame.
Preventing gas leaks and explosions requires eliminating these three conditions. Daily life in the use of natural gas or liquefied petroleum gas after the completion of the need to immediately shut down the operation, if not used for a long time or out of the house, you need to close the home of the main valve. Don't place electrical appliances that can generate heat near the pipeline, electrical appliances will lead to accelerated aging of the pipeline, such as microwave ovens, ovens, air fryers, etc., and the kitchen must be kept ventilated and cooled to avoid too high a temperature. The service life of the cooker should not exceed 10 years, the cooker must choose a safe and reliable brand, after-sales service is guaranteed. When the gas is turned on, do not leave the kitchen, to avoid the wind or water will flame out, resulting in gas leakage. Regularly check the gas connections and piping, do not privately modify the gas piping and equipment, be sure to hire professionals. The storage space for liquefied gas cylinders should be cool, dry and ventilated, and there should be no source of ignition.
