The order states that offices can open from 9 am to 5.30 pm or from 10 am to 6.30 pm.
Given the severe air pollution, the Commission for Air Quality Management (CAQM) has taken strict measures and made changes to the Graded Response Action Plan (GRAP).
Changes in GRAP-3 and GRAP-4
Under the revised guidelines, it has been made mandatory for NCR states to close offline classes of schools up to Class V in GRAP Phase 3 and up to Class XII in GRAP Phase 4.
A new directive has also been added under Stage 3 in the revised GRAP, in which state governments need to set different timings for public offices and municipal bodies so that traffic and pollution can be reduced. Under GRAP Stage 4, people have been advised to wear masks outside during dangerous air quality.
Change in weather, the cold wave begins
These days the weather is constantly changing in the entire country, including Delhi-NCR. Cold has set in in most of the states of North India. The mercury has dropped in Delhi NCR for several days. However, due to the smog clearing and relief from fog, the Air Quality Index (AQI) fell on Thursday.
This has improved the pollution level. Due to this, people breathed in cleaner air than in the past days. The sky also remained clear throughout the day. There was fog in the morning and mild sunshine during the day.
The AQI of the capital is still in the severe category
