A lot of yellow smoke on the ground in Hangzhou is a gas leak. When gas leaks, what other circumstances can lead to explosion besides open flame?
When gas leaks, besides naked flame, attention should also be paid to the explosion when the gas reaches a certain concentration, and some friction heat can also lead to the explosion.

When the gas company came to check, it reminded users of the general situation: once it smells a gas leak indoors, it must be checked in time to see if the valve is closed.

In case of gas leakage, it is necessary to prohibit the use of naked flame, not to smoke at the scene, and to use lighters or matches, otherwise it will detonate at the first time.

Don't touch those metal products when there is a gas leak. Once the friction of metal products generates heat, it will also lead to gas explosion. When we have smelled that pungent smell, we must not call the mobile phone, which will also cause a sudden explosion.

Don't touch all metal objects. At this time, the valve is closed urgently for ventilation. Evacuate people in an emergency, and don't run violently to avoid gas explosion.

In case of gas leakage accident, you must call the police in time, call the gas company, let professionals handle the scene, and close the gas valve in time. Organize relevant personnel to carry out emergency evacuation, and don't stay or wait and see at the scene of the accident. Safety is guaranteed. Cooperate with the gas company to do a good job in security inspection. Every household should carefully check, and the gas appliances in users' homes should be replaced in time. Unqualified products should not be used. If there is a safety accident, it must be a big problem.

Things related to life safety must not be underestimated. Gas safety is closely related to our life, so we should do a good job of inspection and self-examination.
