Covid-19 assessment - Decontainment management in companies

How to reintegrate our administrative buildings?

This « Coronavirus » crisis that has been affecting us for more than a month now, is unprecedented and is still not over. However, recent communications from our Government give us hope that the economic restrictions will gradually be eased - provided that the easing measures taken do not affect the declining trend of contamination.

Law of September 23, 2020 modifying the amended law of 17 July 2020 on measures to combat the Covid-19 pandemic.

Before going any further on the matter, here is a brief description regarding the mode of spread of this virus.

A person with Cov-2 SARS coughing or exhaling droplets of infected fluid. Most of these droplets fall onto nearby surfaces and objects. In workspaces, these are work surfaces, screens, keyboards and mice or telephones. It is possible that people touching these contaminated surfaces or objects — and then touching their eyes, nose or mouth — could become infected. A person who stands for at least 15 minutes with less than 2 meters’ distance from another person contaminated with the virus can be infected by inhaling droplets from a coughing fit or simply by exhaling.

The aim of this document is to try and give some practical advices regarding the questions that will arise during the gradual reintegration of our work spaces. < br /> The following measures and advices will be regularly re-examined and adapted in accordance with the evolution of the state of crisis and governmental recommendations.
