학교 마스크, 에어컨 최소 2번 환기, 마스크 야외운동장 외 상시 착용<br /><br />Some 2-point-4 million students nationwide on Wednesday went back to the classrooms for the first time in nearly three months.<br />On the first day of the second phase of schools reopening, South Korean health authorities unveiled a set of guidelines on the wearing of face masks and use of air conditioning at schools.<br />Also in the guidelines: no singing rooms or internet cafes for students after school.<br />Our Lee Kyung-eun reports.<br />The Central Disaster and Safety Countermeasure Headquarters announced on Wednesday that schools are allowed to use air conditioners when two criteria are met.<br />"Air conditioning could contribute to the re-circulation of the air trapped inside classrooms, so it is important to pay attention to ventilation and the strength of the wind created by the air conditioner."<br />For that, the health authorities advise schools to open windows at least two times every hour.<br />Face masks are mandatory in places where opening windows is not possible, and those places should not be entered by potential patients.<br />This middle ground aims to satisfy students and parents who wanted air conditioning while keeping windows open,...as the government and schools have raised concerns over the environmental and economic burden.<br />The air conditioning must be kept on a low setting so that it can lower the possibility of the virus traveling around the classroom.<br />Students must keep face masks on the whole time when inside the school building.<br />That includes during break time.<br />They can only take them off when outdoors, like on the school soccer field.<br />The two exceptions to this are,...when they are doing small group activities where a 2 meter distance can be kept... or if they have a headache or difficulty breathing.<br />Every student should also carry extra face masks so that they have a spare in case of contamination.<br />"As the weather gets warmer and the risk of COVID-19 remains, these guidelines can help students stay safe and cool.
