Dear SST Students,
In view of the worsening haze conditions, we will use a red flag placed in the middle of the field to signal when outdoor unstructured play is suspended. Please look out for a red flag in the middle of the field, as shown in the photograph below.
If the flag is up, all outdoor unstructured play is suspended. This applies to the field and all other outdoor spaces in school. The flag will be placed when the 24-hour PSI exceeds 100, or the 1-hour PM2.5 reading exceeds 56µg/m³.
Please follow this arrangement even if the air appears clear. You may resume unstructured outdoor play only after the flag has been removed.
Thank you for your cooperation.
