Air Quality Monitoring
YISS monitors the air quality on campus and in the Yongsan area throughout the day so that school activities can be modified accordingly. Decisions concerning any potential alterations or cancellations of school will be made in consultation with local education and health authorities.
YISS has over 100 air purifiers installed in classrooms, multi-purpose rooms, and other shared spaces to help remove impurities in the air to provide a healthier learning environment.
Elementary students do not go outside for recess, PE, or outdoor field trips if the fine particles (PM2.5) level reaches 36 or the coarse particles (PM10) level reaches 81, and middle and high school students remain indoors if the fine particles (PM2.5) level reaches 76 or the coarse particles (PM10) level reaches 150. Athletics events follow the yellow dust/air quality procedures outlined in the KAIAC By-Laws. KAIAC member schools have set 300㎍/㎡ (yellow dust) and 150 (CAI) as a cut-off for permitting outdoor athletic competitions.
Some students may have respiratory conditions and sensitivity to fine dust and thus, when pollution levels are high, parents are encouraged to consult their healthcare providers to determine the necessary precautions for each child.
