A firefighting drone was recently unveiled in Henan province to help extinguish fires on tall buildings and support emergency rescue, Science and Technology Daily reported on April 8.

The firefighting equipment unveiled consists of one pilot-less helicopter and three drones, and four rescue nacelles, all stored in a fire engine, according to Predator Firefighting Technology, the Henan-based developer.

Zhang Wanmin, a senior firefighting engineer, said the equipment is the first in the world that can extinguish fires in buildings above 100 meters. The drones, which can fly for four hours carrying 100 kilograms, could deliver materials to accident sites in a timely manner, reduce safety risks and significantly improve operational efficiency.
