Save these numbers now, not later
Ambulance: 102. Police: 100. Fire: 101. Women's Helpline: 1091. These take ten seconds to save and matter far more in the moment than they seem like they will right now.
Where to go
AIIMS Trauma Centre, about 2 km from Katwaria Sarai, is the nearest major facility for serious emergencies and operates 24/7. For less urgent but still pressing issues, Care Clinic in the market handles general consultations without the wait of a full hospital visit.
If it's not you calling
If you're helping someone else, try to have their location, a rough description of what's happened, and any known medical conditions ready before the call connects — it speeds up the response noticeably.
