Wearing a mask can stop you from developing the symptoms of COVID-19 and respiratory illness caused by inhalation of hazardous substances at work (for example, coughing, wheezing, shortness of breath, chest tightness or difficulty in breathing).
Lets look at when and how one can use a nose mask.
When to use a nose mask
- If you are healthy, you only need to wear a mask if you are taking care of a person with COVID-19.
- Wear a mask if you are coughing or sneezing.
- Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.
- If you wear a mask, then you must know how to use it and dispose of it properly.
How to use a nose 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.
- Avoid touching the mask while using it; if you do, clean your 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 re-use single-use masks.
- To remove the mask: remove it from behind (do not touch the front of mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.
