When the natural gas alarm is finished, first, don't panic. The design of natural gas leakage alarm has established a dangerous level before the gas goes out. Their ratings are based on their lower explosive limit (LEL), which means that LEL's gas reaches the percentage before the alarm goes out. That is, your house is in danger of explosion. If your combustible gas detector is triggered at 15% LEL, this means you have enough time to reach the risk level before taking action. Next, make sure there is no open fire. If so, put them right away! This includes cigarettes, candles, or what is burning in your house.
Natural gas is extremely flammable, flammable, open fire, plus gas in the air equals fire or explosion. Turn on any gas appliance and put any indicator light. Do not touch or operate any electrical equipment. This includes even the phone. Likewise, even a small spark can ignite the gas. Don't pull off the electrical appliances. If you need light, use a battery powered flashlight. Open all doors and windows to disperse the gas. If you still close the gas leak detector, or you suspect there is a certain leak, open the main gas house. Call your fire department and gas companies outside your house, whether on mobile phones or from neighbors. and you need to be in a hurry to move out of the house.
