Provincial Epidemic Prevention and Control Leading Group Propaganda Group: Prevent gas backflow.
First, when the wash basin is not in use, the drain at the bottom of the basin should be closed, and then a small amount of water should be added to form a sealed blockage. Open it when using the wash basin.
Second, use a deodorizing floor drain, or use a sealed plastic bag filled with water and tied tightly to block the floor drain opening. Remove it when using the floor drain.
Third, during the epidemic, the bathroom exhaust fan can be blocked with plastic film and adhesive tape to avoid the potential risk of gas backflow.
Fourth, after using the toilet, close the toilet lid before flushing.
Fifth, when using the range hood, the wash basin, floor drain, toilet, and exhaust fan should be blocked. You can also open the windows at the same time to ensure gas exchange, avoiding the negative pressure created by the range hood causing potential polluted gas to backflow through indoor pipes; when not in use, it can be temporarily blocked with plastic wrap and adhesive tape.
