After Thursday night’s showers, Delhi’s air did improve on Friday morning, swinging from “poor” to “satisfactory–moderate” at several stations. That relief sparked confusion about whether the pollution phase ended and fireworks are fine again. The science and the orders say otherwise. Students should read rules by date, not headlines or forwards.
Rain scrubs particles briefly; it does not fix winter inversions or upwind smoke. The Commission for Air Quality Management invoked GRAP Stage I across NCR on October 21, 2026, and it stays until the Sub‑Committee revokes it. Check status before planning outdoor study groups.
Are firecrackers allowed in Delhi-NCR now?
In Delhi (NCT), a standing government direction imposes a complete ban on manufacture, sale, storage, and bursting of all firecrackers. Outside Delhi but within NCR, permissions vary by state and district, and follow the Supreme Court’s recent “no total ban” balancing approach and time windows.
Green crackers and student health: facts over myths
Green crackers cut some emissions, but they are not harmless. NEERI says reduced‑emission formulations lower particulates and gases by around 30 percent, yet studies report spikes in ultrafine particle counts and lingering metal exposure risks. Teens with asthma should avoid exposure and keep reliever inhalers handy.
Travel and exam-day readiness by AQI band
Use AQI bands to plan commutes and exam logistics. Friday’s improvement may fade as winds slow and moisture traps pollutants, so carry masks and buffer time for visibility or transport curbs. Monitor the CPCB dashboard the evening before an exam or campus visit.
| AQI band | What students should do |
|---|---|
| Satisfactory (51–100) | Commute as planned; keep windows shut in traffic. |
| Moderate (101–200) | Limit outdoor study; carry a snug medical mask. |
| Poor (201–300) | Switch to indoor practice; avoid runs; watch GRAP advisories. |
| Very Poor (301–400) | Reschedule non‑essential travel; N95 mask; asthma plan ready. |
| Severe (401+) | Stay indoors; use purifier room; coordinate with centre helplines. |
Verify official orders fast: DPCC, CAQM and CPCB dashboards
Check three places before acting: CAQM website for GRAP stage and any fresh curbs, DPCC or Delhi Environment pages for city‑specific cracker and construction orders, and Delhi/CPCB AQI dashboards for real‑time bands. Avoid forwards; screenshot the order header with date and number.
Key takeaway for this week: rain helped, but winter pollution dynamics persist. Delhi’s cracker ban remains; NCR permissions depend on district orders under the Supreme Court’s balanced framework. Track CAQM and DPCC daily, plan exam travel by AQI band, and prioritise respiratory health over celebration noise or social pressure.
