Sealed

Sealing refers to places where there are no windows or no ventilation.[2]..It has been pointed out that there is a possibility that the virus concentration in the air will increase in a poorly ventilated space and there will be a risk of infection, and cases of actual infection have also been reported.[3]..As a countermeasure, sufficient ventilation is important regardless of the size of the room.[1][2]..At the Prime Minister's Office of the Ministry of Health, Labor and Welfare, in the case of a room with windows, the windows in two directions should be fully opened for several minutes to ventilate at least twice an hour, and for air conditioners such as passenger cars and trucks, the "outside air mode" should be set for trains and buses. Public transportation such as is calling for cooperation in opening windows[1]..The term "closed space with poor ventilation" is considered to mean that the air environment of a general building does not meet the standards.In that sense,Building Management Law StandardsIf the ventilation volume required to meet the requirements (per capita ventilation volume of about 30 cubic meters per hour) is met, it is considered that this does not apply to "a closed space with poor ventilation".[1][4][3]..Therefore, there is no need to worry too much even in a facility without windows, but it is necessary to further increase ventilation and reduce the number of people per room.[1]..In addition, since ventilation is not performed with a normal household air conditioner, separate ventilation is required.[1].

Dense

Dense means that many people gather or even a small number of people gather at a short distance.[2]..As a countermeasure, even if you reach out to each other with other people, you can not reach itEnough distanceIt is effective to keep (2 meters or more, at least 1 meter)[2].
