Thank you for the question.
I am not an expert on equipment. When my colleagues appear before the committee, they will be able to give you a more detailed answer. In any case, all these factors will be examined before we consider a major, permanent return to the workplace.
In addition, public health experts make distinctions regarding airborne spread. Given that I'm not a public health expert, I would not want to get into the subtleties of this issue.
I invite you to ask the experts.
