🐘How to put on, use, take off and dispose of a mask?
When to use a mask?
Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.
Cover mouth and nose with mask and make sure there are no gaps between your face and the mask.
To remove the mask: remove it from behind (do not touch the front of the mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.
Replace the mask with a new one as soon as it is damp and do not reuse single use masks.
