Use of face masks and visors

Face masks can be used as a supplement for preventing the spread of infection in situations where it is difficult to keep to distance. It is important that you continue to follow the advice relating to keeping a distance and good hygiene even when you wear a face mask.

In Greenland, you must wear a face mask in the following situations:

  • All individuals aged 12 years or older on domestic or international flights (face masks must be worn to the quarantine location/end destination).
  • If you have been infected or risk of being infected with COVID-19 and in exceptional circumstances must move outside, e.g. because you need to get tested.

A face mask should be a disposable face mask or a face mask made from fabric, which covers the nose and mouth, which is attached to the face using a cord, elastic or similar behind the ears or behind the head, and fits tightly around the face.

CE-marked face masks
When having to wear a face mask in public areas, it is recommended that you use CE-marked face masks. It is also recommended that CE-marked face masks are worn by persons who have an increased risk of serious illness or if you are infected with COVID-19.

The CE mark means that the manufacturer can document the quality of the face mask. It is sufficient to use a CE-marked type 1 face mask. It protects you against infection from other people and other people are protected from being infected by you.

Face mask made from fabric
Regardless of whether you purchase a manufactured face mask made from fabric or make your own, they are not subject to the same quality standards as CE-marked face masks.

If you choose to wear a face mask made from fabric, there are some things that you must know to ensure that your face mask works in the best possible way. For example, it must have three layers of fabric. It must be equipped with elastic and fit tightly to the face, so that it covers both the nose and mouth. The fabric must be weaved densely enough so that it can filter the air, but you should also be able to breathe easily. It must be able to be washed at 60 °C.

Face shield visor
A face shield visor is recommended as an alternative to a face mask in situations where a face mask is not suitable. For example, for persons who cannot use a face mask or in situations where it is necessary to be able to see the face of the person.

A face shield visor is a plastic screen that covers the face, nose and mouth or nose and mouth, and this can act as a barrier against virus particles. A face shield visor does not fit closely around the face and the quality can vary, which affects the degree of protection. If you use a face shield visor, it is crucial that you are aware that the degree of protection is reduced since it does not fit tightly around the face. A face shield visor like a face mask made from fabric is not produced in accordance with common industrial standards, which means that the quality can vary. Unlike a disposable face mask, a face shield visor can be used for a whole day and some types can even be washed and reused.

The face shield visor must be handled correctly just like a face mask, i.e. it should not be touched when used. It must be removed occasionally and at the same time wash or disinfect your hands with hand sanitiser to avoid being a potential source of infection.

Industrially manufactured face masks are disposable products, which in general should be disposed of after use. Face masks must always be replaced if they become wet, dirty or are touched, as they can lose their protective effect. It is recommended that you do to wash disposable face masks in order to reuse them. When a face mask is washed it affects its filtering property and its breathability, so that the face mask will not provide the same level of protection.

Wear a face mask in public areas and dispose of as ordinary waste. After disposing of a face mask, you must wash your hands or disinfect your hands using hand sanitiser.

If you wear glasses, you may find that condensation forms when you wear a face mask. It may irritate you and impede your vision, and it can increase the risk of infection from contact if you repeatedly touch your glasses. We therefore provide here some good advice for how you can prevent condensation forming on your glasses.

  • Ensure that you choose a face mask that fits completely tightly around your nose and mouth, e.g. a face mask with a metal strip, which can be pinched around the nose.
  • Place the face mask as close to your eyes as possible and wear your glasses a little bit lower down on your nose.
  • Clean your glasses with warm water and a couple of drops of detergent every morning and evening. Soap reduces the risk of condensation forming on your glasses.
  • Dry your glasses using a microfibre cloth.

If a child is to use a face mask, it is important that the child understands how to wear it correctly. It is important that the face mask is not overly loose on the child’s face and that the child can take the face mask off and put it on. Children of school age typically can do this.

Children under 12 years of age do not generally have to wear face masks.

You can help toddlers, who cannot use face masks by keeping their hands clean and paying attention to any signs of COVID-19 symptoms.
