Drones are used in emergency situations for several purposes, including:

1. Search and rescue: Drones equipped with cameras and thermal sensors can be used to search for people or animals in disaster-stricken areas, where it may be difficult for rescue workers to reach.
2. Disaster assessment: Drones can be used to survey the extent of damage caused by natural disasters such as hurricanes, earthquakes, and floods. The aerial view provided by drones can help rescue teams prioritize their efforts.
3. Delivery of medical supplies: Drones can be used to quickly deliver essential medical supplies, such as vaccines, to remote or hard-to-reach areas.
4. Firefighting: Drones equipped with cameras and thermal imaging sensors can be used to monitor and control the spread of fires.
5. Traffic management: Drones can be used to monitor and control traffic in emergency situations, such as accidents, to ensure the safety of drivers and emergency workers.

These are some examples of how drones are being used in emergency situations to save lives, provide real-time information, and support rescue and recovery efforts.
