The government, the social partners, and trade associations have agreed on safety measures that provide for the separation and adoption of personal protective equipment. These include masks. During these months of coronavirus alert, we have learned to familiarise ourselves with the different models. It is less clear when in the workplace, depending on the type of occupation, it is recommended to wear one type of mask instead of another.
Very high risk
Jobs with a very high risk of exposure are those with a high potential for exposure to known or suspected sources of Covid-19 during specific medical, post-mortem or laboratory procedures. Workers in this category include: • Healthcare workers (e.g. doctors, nurses, dentists, paramedics, emergency medical technicians) involved in procedures that generate aerosols (e.g. intubation, procedures that may involve induction of coughing, bronchoscopy, some dental procedures and examinations, collection of invasive samples) on known or suspected Covid-19 patients; • Healthcare or laboratory personnel involved in collecting or handling samples from known or suspected Covid-19 patients; • Medical and technical personnel of the morgue service involved in performing autopsies (generally involving aerosol-generating procedures) on the bodies of people known to have, or suspected to have, Covid-19 at the time of their death.
Jobs with a high risk of exposure are those with a high potential for exposure to known or suspected sources of Covid-19. Workers in this category include: • Staff dedicated to health care (e.g. doctors, nurses and other hospital staff) who may come into contact with known or suspected Covid-19 patients (Note: when such workers perform procedures that may involve aerosol generation procedures, their level of risk of exposure becomes very high). • Operators involved in the transport (e.g. paramedics and ambulance service workers) of known or suspected Covid-19 patients in closed vehicles. • Mortuary workers involved in the preparation (e.g. for burial or cremation) of the bodies of persons known to have, or suspected of having, at the time of their death. • Medium exposure riskJobs at risk of medium exposure include those requiring frequent and/or close contact (i.e. within 1 metre from) with people who may be infected with Sars-CoV-2, but who are not known or suspected Covid-19 patients. Workers in this category may have frequent contact with the public (e.g. goods and merchandise delivery personnel, security or public order personnel, workers in retail or wholesale outlets, etc.) and other colleagues.
Workers at low risk of exposure are those employed in jobs that do not require contact with people suspected or known to be infected by Sars-CoV-2, nor frequent close contact (within 1 metre from) with the public and other colleagues.
