Air Quality Update
As you know, we have been carefully monitoring the air quality at the High School, especially given the high AQI figures since the beginning of this term.
Last Wednesday, even though the AQI did not reach the 200 threshold for moving all activities inside, we cancelled all outdoor PE and swimming lessons and football and basketball at break and lunchtime. As I said at the recent PTG Meeting, we make these decisions based on our live data from the AirVisual Pros that we have around the High School, and the readings last Wednesday morning were not improving after the morning rush-hour as they usually do.
Early on Wednesday afternoon we heard officially that, due to the very high PM 2.5 levels, the Ministry of Education had closed all schools in Bangkok for Thursday and Friday. This also meant that we had to make the difficult decision to postpone this year's Fun Day, which was due to take place on Saturday. As Paul has written in his Head’s Lines, we will be working with the PTG to explore the possibilities of re-arranging this later this term.
As I wrote last week, while most of the High School was away on Residentials we replaced the 3M Filtrete™ Electrostatic Air Conditioner Filters in our air conditioning units all over the High School. These ensure that even when the air quality is poor outside, the air quality in our classrooms, where the students spend the vast majority of their day, is much better.
