Proper use of fase masks

Proper use of fase masks


Use of a face mask is mandatory in all places and environments.

The correct use of a face mask, that is, covering the nose and mouth, is critical to avoid contagion; likewise, it is very important to remove the mask to avoid contact with contaminated areas or dispersion of the infectious agent.

Cloth masks may be used, as long as they comply with the indications defined by the Ministry of Health and Social Protection detailed in:


The use of surgical masks is recommended for elderly people and individuals with comorbidities.

Adjust the fase mask, if it has elastics behind the ears; if it has straps, it should be tied above the ears at the back of the head and the lower straps, below the ears and above the neck.

Placement of the fase mask should be over the nose and under the chin.


The blue colored (waterproof) side of the face mask should be kept as the external side. Due to its design, the filtering does not have the same characteristics in one direction and in the other, and its wrong placement may result in less protection for the individual.

The face mask can be used for up to 8 hours continuously, as long as it is not broken, dirty or wet; in any of these conditions it should be removed, disposed of and a new one put on.

Once removed, fold the face mask with the external side facing inwards and place it in a paper or garbage bag.


Do not reuse single-use or disposable face masks.

The  face mask should be kept in its original packaging if it is not going to be used or in sealed bags.  It is not recommended to keep them without packaging in the bag or pockets without protection because they can be contaminated, broken, or damaged.

Face masks should not be left unprotected on any surface, such as tables, shelves, equipment, desks, among others, due to the risk of contamination.

The use of face masks with exhalation valves or of elastic or mesh materials is not recommended.

Use of face masks in children and adolescents
  • Children under 2 years of age should not wear face masks of any kind due to the risk of asphyxia and suffocation, nor should they wear visor-type face shields.
  • Avoid the use of face masks in children and adolescents with altered state of consciousness or any physical or intellectual disability that prevents proper handling, as well as with certain chronic respiratory pathologies that may be affected by their use.
  • Face masks should be of adequate size and fit, avoiding gaps between the mask and the face.
  • The face mask should be changed if it becomes wet with sweat or secretions, or if it is torn or visibly soiled.
  • Scarves, hats, or balaclavas are not a substitute for a face mask.
  • Avoid the use of double masks in children, due to the anatomical characteristics of their airways.
