Air Quality Policy

Our school does whatever it can to provide a safe and secure environment for our community. Part of this environment is the quality of the air that we breathe. Obviously, there is a limit to what WISS can do for general air quality in Shanghai, which is not very good compared to many cities around the world. This is one of the things we accept when we come to work and live here. However, we can shape our daily routines to try and minimize the potential for hazardous effects caused by pollution. 

In consultation with other schools in Shanghai, WISS follows the Air Quality Index (AQI) standards laid out by the US Environmental Protection Agency (EPA.) These standards are held in high regard around the world. Of course, when interpreting the results, we do have to accept higher pollution readings as a way of life in Shanghai. 

Below is a chart laying out the AQI scale from 0 to 500:

 Offices are to monitor the AQI using the monitoring station located at WISS (use QR code to see latest reading). Offices are to email all relevant staff before 8:00am, 10:00am, 12:00pm, and 2:00pm. If pollution indicators rise to certain levels, the school will take action.

 

AQI Levels and WISS action 

 

If the AQI is between 0-99

  • Normal play and PE 
AQI QR Code

If the AQI is between 100-149

  • Normal play and PE
  • All windows and external doors will be closed
  • All air filters will be turned on

 If the AQI is between 150-174

  • Today is normal play and PE
  • STUDENTS AT RISK (asthma etc.) must stay inside
  • All windows and external doors will be closed
  • All air filters will be turned on

If the AQI is between 175-199

  • All play and PE must be inside
  • STUDENTS AT RISK (asthma etc.) are excused from participating in PE
  • All windows and external doors will be closed
  • All air filters will be turned on

 If the AQI reaches 200

  • All strenuous physical activities, outside or inside, are cancelled.
  • All windows and external doors will be closed
  • All air filters will be turned on

 This is a very simple procedure, but the details surrounding Air Quality are very complex. There are issues surrounding the quality of indoor air and there are issues surrounding the kind of particulate matter in the air and the size of the particles. This simple system reduces risk significantly and can be applied relatively easily.
