Spraying of sanitizer through drones is prioritized for hot spots and containment areas, followed by Isolation areas, quarantined areas, shelter homes and other places where manual spraying is difficult.

The areas where Drones are to be deployed is decided by a team of officials, which first visits the area planned to be sanitized for the day, makes a quick visual survey of the terrain, buildings and surroundings and chalks out a flight path to be followed by the drone. The drone is then filled with 1% Sodium Hypochlorite, calibrated and flown using a remote-control device in the planned flight path, spraying sanitizer through its four nozzles.
After every flight (lasting approximately 15 to 20 minutes) the drones are called back for refilling the chemical and replacing the battery pack. The average cost of operations ranges from INR 8,000-12,000 per day per drone, and is dependent on area covered. Image courtesy:www.Indiainfrahub.com
