In October 2020, in the Kangle Community in Gansu, several children played in the community. Among them, brown clothes children suddenly stepped on the manhole cover, squatted to the septic tank and threw firecrackers. Instantly, the boy flew 3 meters and fell heavily on the ground.

How to prevent a biogas explosion in the toilet?

1. Try not to throw things in the toilet, causing the toilet blocking. Once the toilet is blocked, it should be dredged in time, otherwise it is easy to produce biogas. When the biogas reaches a certain concentration, it will cause the air to explode.

2. Do not throw cigarettes such as cigarette butts in the toilet.

3. If it is a farm toilet, holes need to be reserved at the septic tank, which is convenient for biogas in the pool to discharge in time. At the same time, you should pay attention to ventilation and ventilation in the toilet to avoid explosion.

4. Once a similar explosion occurs, the doors and windows should be opened in time to cut off the power supply, especially the power in the toilet to avoid causing secondary disasters.

Finally remind you again:

Remember

Don't be in areas where there may be biogas

Smoking or using bright fire

There is no trivial matter in life

Don't cause tragedy because of careless or curiosity
