Can I wear a cloth face mask in a laboratory?
You should maintain appropriate social distance in your work area, so the cloth face mask should be considered more for your travel to and from the laboratory and not to be worn in it. If a cloth face mask is worn in the lab space, it should be handled the same as your lab coat and therefore not worn outside of the lab again or in other public spaces. It may remain in the lab for your personal use only and washed as your lab coat would be.
A cloth face mask does not replace any other recommended or required personal protective equipment (PPE) for your duties or workspace, such as goggles, face shields or respirators, and it should not interfere with the fit or function of other PPE.
