Air Quality Index (AQI)

KRMGS strives to provide students and staff with an environment that maintains and manages the highest standards of indoors air quality possible.

1. Infrastructure

(a) Measures have been taken to ensure the school environment is safe & healthy for our students. Some of the measures include but are not limited are :- air purifier in each room, access controls on all entry/exits of the school building, vertical gardens. Additional air purifiers are strategically placed in the corridors

(b) We have set up a real time monitoring network in the school. In addition to a monitor being installed to track outdoor air quality, each indoor zone of filtration has its own real time monitoring solution that updates stakeholders with the results of air quality measured on various parameters. The consolidated results are also shown on a screen in school premises and can be accessed on the school website.

2. Daily Monitoring of External and Internal Air Quality

  •   KRMGS tracks air quality throughout the day by reference to our own AQI monitor in school, the live AQI reading from Air Quality station using the live Air Quality Index(AQI) feed from VikasSadan . At KRMGS we use government reading ,when available , to make decisions regarding red and yellow flag days.
  •  The Indoor Air Quality readings are taken at 8:00 am and 12 noon on each school day.
  •   Readings are recorded forAQI(Air Quality Index) and PM 2.5(the indicator for the most harmful particles).


Outdoor Policy: The School has an outdoor policy which is communicated to the school community on a daily basis through colour coded flags.
We have adopted a two category system to determine whether student’s outdoor activities need to be restricted.
AQI = 250 + (Students ‘outdoor activities & play are restricted)

Red Flags: On days when AQI is 250+ red flags are displayed in prominent locations around the campus to convey to the school community that the outdoor activities cannot take place.

Yellow Flags: On days when AQI is lower than 250, yellow flags are displayed in the school campus to convey to the school community that the outdoor activities can take place.

1). Co-Curricular Activities: The Outdoor activity schedule is managed carefully to minimise its impact on students. For example, we utilise a range of indoor spaces within the school to allow students physical activity during red days.

2). Educational Visits: If the standard air quality reading is over 200 the school management will take the call and postpone the trip. All the necessary arrangement will be made by the school office and communicated directly with the parents.

Awareness: Environment Awareness Actions are undertaken by the students throughout the academic year. Campaigns and Assemblies are conducted regularly to generate awareness about the causes of pollution and the measures to be adopted to combat it
