Before putting on any mask, thoroughly clean your hands with an alcohol-based hand rub or soap and water. Cover your mouth and nose with the mask and make sure there are no gaps between your face and the mask. Avoid touching the mask and your face while using it. If you do, make sure you keep your hands as clean as possible. Replace the mask with a new one as soon as it is damp and do not re-use single-use masks. To remove the mask: remove it from behind the ears (do not touch the front of mask); discard immediately in a closed bin.
