Delhi experienced over 300 fire-related incidents during Diwali, according to the Delhi Fire Service (DFS), though no life-threatening cases were reported. DFS director Atul Garg highlighted that from 5 PM to 6 AM, calls surged, exceeding 300 incidents. The presence of additional fire forces during the festival helped prevent major fires, although minor incidents, including one in Vikaspuri where two individuals were rendered unconscious, did occur. Another incident in Mangolpuri led to injuries for a woman and two children.
A significant call involved a Delhi Transport Corporation (DTC) bus in Najafgarh, where a man carrying potash—a substance used in firecracker manufacturing—caused a blast, injuring two people. Fire tenders were dispatched to the scene. Additionally, Delhi Police reported an incident of firecracker-related burn injuries to a bus passenger and a co-passenger.
Following the celebrations, air quality in Delhi deteriorated, with AQI readings surpassing 350 in several areas, raising health concerns. Notably affected regions included Anand Vihar, Aya Nagar, Jahangirpuri, and Dwarka. Similar pollution spikes were reported in other cities like Chennai and Mumbai.
