Is it not safer to have mask mandatory for all plant employees as a preventive action?

Since an asymptomatic worker can carry the virus, all plant staff working in close proximity with inadequate physical distancing measures in place should be equipped with at least non-medical face masks. These masks should not replace the existing workplace respiratory protection program requirements; Another type of mask or respirator may be indicated based on a task-based hazard assessment, so your respiratory protection program should be re-evaluated and revised as needed to address biological hazards such as COVID-19.

If masks are used, they should be single-use and disposed after each use, or laundered after each use in the case of non-medical fabric masks. COVID-19 can remain viable on a mask for 7 days (Lancet).
