Since centralized air-conditioning cannot be used in centralized isolation, natural ventilation is required. The isolation observation point shall be provided with two channels of cleanliness and pollution. The two channels shall not cross to prevent cross-contamination. The excreta and sewage of isolated observers need to be disinfected before being discharged into the municipal pipe network.

[Explanation] It is reported that there is a temporary storage point for domestic garbage of segregated observers. The temporary storage point will be located in a remote and inaccessible place for people, and the temporary storage point must have a lid.
