What disinfection of Covid-19 before reopening?

At this time of Covid-19, cleaning offices is a priority to ensure a healthy environment for your employees and to limit the spread of Coronavirus.
- Under what circumstances is disinfection of the premises necessary?
- What cleaning products are effective against coronavirus in offices?
- How can you reassure your employees?
Before reopening the premises, it is first necessary to choose the appropriate disinfection / decontamination solution after the confinement period. It is then important to communicate the system in place, in order to reassure employees.
The most important parameter to consider when considering the right disinfection solution is: the occupancy of your offices during confinement.

Why does the occupation of offices directly impact the disinfection solution?

The survival time of the Covid-19 coronavirus varies from a few minutes on the skin, up to 12 hours on masks and clothing, up to 4 days on wood, up to 5 days on metal and glass, up to 9 days on plastic (source: WHO and Ministry of Health)
Two scenarios are therefore to be studied: whether or not your premises were occupied during the 10 days preceding the end of confinement.

First case

There was a visit to my office 10 days before the arrival of the employees
If the offices continued to be used during confinement, one person is sufficient, consideration should be given to complete decontamination of the premises. This solution eliminates any risk of the presence of the Covid19 virus. Disinfectants kill germs, but not necessarily the viruses that may remain. Disinfection by nebulisation guarantees complete elimination of the virus in offices via a precise decontamination protocol. This disinfection process consists of spraying a product in the form of a mist via a cold nebuliser. The product destroys 99.99% of bacteria and eliminates a wide range of diseases.
Its virucidal action certified EN14476 is effective against the Covid-19. An example of a product used for nebulisation: STERI-7.
When nebulised, disinfectant particles spread absolutely everywhere in offices, for disinfection of all areas of the place.
Disinfection by nebulisation requires no rinsing, does not stain, is alcohol-free, non-corrosive and non-irritant.
The process is carried out in empty premises, with a total idle time of 8 hours, including drying. It is necessary to disconnect all electrical devices before the intervention (household appliances, fire alarms, IT equipment, etc.)
The price of these interventions is calculated according to the volume of the spaces concerned.

Second case

Empty offices during confinement
If your offices have not been occupied for the 10 days preceding the reopening, you do not need a complete disinfection of your offices by nebulisation.
However, cleaning passages before the reopening of the premises by your cleaning team are important. This guarantees clean offices and reassures employees, for whom the end of the home office and the return to the office will surely be anxiety-provoking.
Then find out about the products that will be used by your recovery company: are they virucidal and therefore effective in eliminating Covid-19?
These products will be essential to contain the spread of the virus, in particular on contact points (handles, switches, etc.) and in common places.
