Based on internal studies and in collaboration with international partners, VOA prepared this information circular for Spraying for Disinfection of Surfaces and Places. The purpose of this circular is to inform anyone interested, including and not limited to the VOA franchise and service network itself, of the possibilities for using Drone Technology for spraying services for the purpose of disinfection for mitigation, delay and reduction of spread of viruses in public places, streets, industrial and hospital yards, squares, among others.
In parallel, VOA launched a new area, called “Urban Spraying”, on its service platform. This area is available to receive any disinfection requests from authorities and other interested parties in any location in the national territory.
On the other hand, VOA is providing a channel to receive registrations from drone operators that have technical resources (drones, technical training) for spraying. Based on this, we will be able to facilitate that eventual demands for Disinfection are met by trained regional operators.
After your initial registration, we will contact you. If you need, contact us by phone +55 12 3911 1881 or Whatsapp +55 12 99609 4343
International authorities and WHO work together to control the spread of the COVID-19 virus. Global governments and authorities are actively working on strategies, methods and procedures to slow and slow the evolution of the epidemic that is present today.
VOA together with the main manufacturers of industrial drones in the world has developed methods of using drones against the coronavirus using our technology to protect people's lives.
The VOA-001 and VOA-002 drones can be used to deliver a mixture of water and chlorine-based disinfectants to affected locations and areas. A drone has a maximum daily capacity in hectares of approximately 20 hectares and, therefore, can spray an average of one location per day. Drones can be handled by pilots specially trained by VOA, or by operators already trained by authorities and companies.
In addition to helping to disinfect buildings and street objects, drone spraying plays an important role in minimizing the potential for coronavirus to spread to potential virus-carrying birds and mammals, such as mice and other rodents.
The solution that has been used as a quick and effective aid in protecting against the coronavirus is based on disinfectants that have Sodium or Chlorine Hypochlorite or Alkildimethylbenzylammonium Chloride as the main active compound.
There are worldwide references for the use of drones for this purpose. Every day more and more localities are disinfected.
Spraying area:
(1) Public places where people can move, such as factories, parks, schools, gas stations, open markets, bus stations, etc.
(2) Residential district, such as localities, communities, etc.
(3) Area of potential danger, such as isolation districts, hospitals and other risk areas where they may have viruses.
The recommendations here do not replace the operation according to the drone's flight manual, they are only complementary.
Flight Mode
Before Flight
In flight
After the Flight
The disinfectant containing chlorine or ammonia is corrosive. After missions, the equipment must be cleaned and kept free of disinfectant residues immediately.
Based on tests carried out and on the history of applications in the world and in Brazil, one can assume the use of disinfectants whose active principle is:
The tables below provide some guidelines for spraying.
| Purpose | Concentration | Necessary time | Method |
|---|---|---|---|
| Disinfection of Surfaces and Things | 0.1% 1000mg / L | 10 min | 1L of water with 20ml of primary solution |
| Dip disinfection of contaminated things | 0.05% 500mg / L | — | 1L of water with 10ml of primary solution |
| Area Type | Concentration | Altitude | Speed | Volume | Bicos |
|---|---|---|---|---|---|
| Suspected infection area | 0.10% | 3 to 5 meters | 3 to 5 m / s | 3 to 4.5 ml / m2 | 015 |
| Area without suspected infection | 0.05% | 3 to 5 meters | 3 to 5 m / s | 4.5 to 7.5 ml / m2 | 015 |
The operations suggested in this circular are, as a rule, feasible to be carried out while respecting the current legislation for the operation of Drones.
Special attention should be paid to the Brazilian Special Civil Aviation Regulation 94 and ICA 100-40., As provided in the Procedures and Specifications for the VOA Approved, Document VOA-BIZ-100-00.
