“A mask should fit securely around the face, specifically covering your nose and mouth areas,”. “The mask should fit snugly on your face and be secured by ties at the back of your head or ear loops.”
It is also important that you wash or sanitise your hands before putting on and taking it off and don’t touch the front of the mask while it’s on.
You should not take off your mask to talk to others. Remove it by the ear straps, not by pulling it off from the front, which could be contaminated.
“It’s very, very tempting to try and adjust it, maybe pull it down and try to adjust the nose again but as soon as you touch your mask, you’re at risk of contaminating your hands and then contaminating yourself.”
