Covid 19 disinfection of premises and surfaces

In this period of confinement in France but in many other countries, in addition to medical research to overcome this virus, and the essential barrier gestures, it is important to disinfect surfaces that may come into contact with it. The Covid 19 disinfection can be applied now but will have to be applied after containment, when we will be able to return to our lives, our jobs, our activities.

Coronavirus or Covid 19?

This virus that appeared in China earlier this year is a Coronavirus. Coronaviruses are a large family of viruses that cause diseases ranging from the common cold to more severe pathologies such as SARS-CoV or Sea-CoV.

The disease caused by this Coronavirus was named COVID 19 by World Health Organization - OMS.

The incubation period (period between infection and the appearance of the first symptoms) is generally 3 to 5 days but can extend up to 14 days During this period, the subject can be contagious: he or she can be a carrier of the virus before the appearance of symptoms.

Transmission of the virus

The disease is transmitted between individuals mainly by sputum. Close contact with an infected person is considered necessary to transmit the disease: same place of residence, direct contact within one metre when coughing, sneezing or talking in the absence of protective measures. One of the other preferred vectors of virus transmission is contact between unwashed hands and face. Therefore, barrier gestures and social distancing measures are essential to protect against the disease.

But while the virus is mostly transmitted via droplets and direct human-to-human contact, 'it is also possible to catch Covid-19 by touching a surface or object where the virus is present before touching one's mouth, nose or eyes,' according to the Center for disease control and prevention (CDC).

The survival time of the Covid-19 on inert surfaces and objects raises a lot of questions. Some studies predict 12 hours on metal surfaces, 6 hours on clothing or 9 days on wood... 

Disinfection of rooms, surfaces

The WHO states that it is possible to "wash the infected surface with a simple disinfectant to kill the virus", or "wash your hands with a hydroalcoholic solution or with soap and water".

Disinfection is an operation that eliminates or kills micro-organisms and/or inactivates undesirable viruses carried by contaminated inert media depending on the objectives set (AFNOR NF T 72-101 standard). 

Airborne Surface Disinfection (ASD) is a simple and effective method of disinfecting surfaces in a room. It consists of propelling a disinfectant product into the atmosphere through a diffuser. Discover our professional disinfection equipment and products

The advantage of the DSVA is the absence of human intervention, so it can be carried out at night in order to avoid immobilizing a laboratory, an agri-food factory, a train or a classroom that must be operational during the day.

In addition, this method makes it possible to disinfect all surfaces in contact with the air. Indeed, the DSVA, (Disinfection of Surfaces by Air), is carried out in a sealed room and the product will spread throughout the volume until the room is completely saturated by a dry mist.

Reminder of the Disinfection procedure

 " ON CANNOT DISINFECT ONLY A CLEAN SURFACE". The manual or automatic disinfection operation can only be carried out after the visible surfaces have been thoroughly cleaned (washing with a detergent and microfibre wiping). Once this operation is completed, disinfection by Fogging can be carried out with Our disinfection devices

1/ PLACE THE MISTER AS CLOSE AS POSSIBLE TO THE ENTRANCE OF THE ROOM.

2/ PROGRAM THE MISTING TIME ON THE TIMER OF THE MACHINE AND PUT IT INTO OPERATION.

3/ LEAVE THE ROOM

4/ CONDEMN THE ENTRANCE TO THE ROOM (Attach a sign to the door: "DESINFECTION IN PROGRESS")

5/ DETERMINE THE MIST TIME + THE CONTACT TIME OF THE DISINFECTION PRODUCT (contact time for a Virucide = 30 minutes).

6/ ENTER THE ROOM AND REMOVE THE MISTER. ( depending on the disinfectant used, you will need to be equipped with safety glasses + gloves + FFP3 protection mask).
