If the air quality persists in the “severe plus” category for more than 48 hours, emergency measures such as odd-even car rationing scheme, banning entry of trucks, construction activities and shutting down schools are taken under the Graded Response Action Plan, the official said.
The hazardous pollution levels forced a number of people to miss morning walks and other activities.

AQI is now 464; schools in Delhi should have been shut today. As this article points out, GRAP has to be reviewed. According to it, the reading has to remain severe-plus (>500) for 48 hours for schools to be shut. Just not on. pic.twitter.com/SJkXF0sxar
