Choose a mask of appropriate size
Perform hand hygiene before putting on a mask
Face the coloured side of the mask outwards with the metallic strip uppermost.
Position the strings or elastic bands properly to keep the mask in place. Mould the metallic strip to the bridge of the nose. Ensure the mask can fully cover the mouth, nose, chin and fit snugly over the face.
Avoid touching the mask once it is secured on the face.
Perform hand hygiene before and after touching the mask.
