Attention must be paid to the leakage of liquefied gas at home. When we use gas every day, we must remember to turn off the fire. If we use liquefied gas tanks at home, we must not expose them to the sun. If we leave them at high temperature for a long time, it will easily lead to explosion due to excessive internal pressure. Liquefied gas tanks must be placed correctly. Horizontal placement or violent shaking is not allowed. Check whether the fittings and sealing rings of liquefied gas tanks are aging on time. If the liquefied gas tank leaks, it should be sent to the sales outlets immediately, so that the sales outlets can check and maintain it themselves.

If you use natural gas at home, you must remember to open the window for ventilation when using natural gas, because using natural gas in a long-term closed environment will produce harmful gases. When people inhale excessive harmful gases such as carbon monoxide, it will affect people's health, and even endanger people's life and health in serious cases. When there are old people at home, you must install a gas leak alarm. When the old man forgets to turn off the fire and the gas leaks, the gas leak alarm will sound, so that the phenomenon of gas poisoning can be avoided. If there is a gas leak, don't turn on the light or ignite it immediately, it is easy to explode. When you find a gas leak in your home, you must first open the window for ventilation. In this case, the gas will become thinner as the air enters the window.
