Fighting THE SPREAD of COVID-19

The motivation for the proposed concept was based around, how do we offer a value-added service to all forms of industry and still reduce costs without sacrificing the well being of their people.

The concept started with the first challenge being movement of people entering and leaving the workplace. Hence the concept of the sanitising tunnel was born. The main challenges were not so much the design and manufacture of the tunnel, but the real challenge was incorporating a way to ensure that when a person enters the tunnel, that they're entire being and items of clothing get sanitised. In other words, how to get maximum surface sanitisation coverage?

Spray nozzles pose a number of challenges due to the particle size and weight that is generated, allowing gravity to instantaneously pull the particles to the ground. Thus resulting in a lack of surface coverage. The nozzle system in most cases requires a water pump to push the disinfectant and water through the nozzles, thus requiring high volumes of water and disinfectant. In addition to these challenges the floor and the persons clothing ends up getting wet.

We overcame these challenges by using ultrasonic atomisation technology that creates a vapour cloud (mist) of molecules no bigger than 1-micron in size. Due to the size and weight of each water and disinfectant molecule, the particles float in the air resulting in ultrasonic atomisation mist. The mist ensures that a person and items of clothing receives maximum surface sanitisation without them or the floor getting wet.

We then focused on how can we offer the same benefits that the tunnel offers, to sanitise the office, workshop space, workstations, office equipment and machinery. The solution... Is the same ultrasonic technology machine used to operate the sanitising tunnel during the day to sanitise people can also be used every evening for example, to sanitise the office’s, workstations and workshop areas. This operation can easily be executed by trained company cleaning staff. Once the sanitising of the offices or workshops are completed, the machine can be reconnected to the tunnel ready for the next day. The ultrasonic mist does not consist of a high-water concentrate, so it will not cause damage to office equipment like computers, electrical components or furniture.

Not only can the tunnel costs be capexed but this will also aid in reducing company costs by no longer having to pay for outsourcing services.

Example of this cost saving for the purpose of this exercise:

Outsourced monthly sanitisation services per site twice a month at a cost of +/- r 10 000.00 per month. Considering there are five sites, the monthly saving would be +/- r 50 000.00 per month. This would be a saving of +/- r 600 000.00 per annum.

Daily sanitising will create a safe working environment, helping the fight against the spreading of the covid-19 virus and will give all personnel the peace of mind that they are safe, resulting in a positive working environment, removing the anxiety and improving productivity.
