How often do N95 masks change the correct way to wear N95 masks?
Recently, in order to prevent the new coronavirus from buying a N95 mask, we need to know how long it takes to use this mask. And the way to wear the N95 mask is right to play the role of resisting bacteria. Otherwise, wearing the wrong method is not the same as not. Let's give you a popular science below.
How often do N95 masks change?
N95 respirator has a certain service life. With the increase of the use time of N95 masks, the particulate matter filtered will gradually filter up the mesh and increase the respiratory resistance. Moreover, if the mask is thicker, if it is not picked for a long time, the humid climate inside may breed bacteria, and the use and storage methods will affect the life of the fog and haze mask.
The N95 respirator is one of the 9 particulate respirators certified by the National Institute of occupational safety and health. "N" refers to particles that are not suitable for oily purposes. "95" means that the filtration efficiency reaches 95%.n99, and the filtration efficiency of the respirator reaches 99%. Experts suggest that the N95 mask should be changed for two days.
In the case of 3M masks, N95 masks are generally used for 24-48 hours; R95 masks are used for about 8 hours; p95 masks are much longer than N95 masks, and work hours can be 40 hours or 30 days.
Under what circumstances do N95 masks need to be replaced?
When one of the following three cases is found, the N95 mask is changed immediately.
1. N95 respirators are contaminated by foreign bodies such as blood stains or droplets.
2, users feel respiratory resistance increased.
3. N95 mask is damaged.
Can N95 respirators be worn for a long time?
N95 respirators should not be worn for a long time. Because N95 respirators are industrial dust respirators, they have good airtightness and easy to cause breathing problems and lack of oxygen. If there is fog and haze, it is not necessary for the public to wear N95 masks. They can choose kn95 masks or Kn90 mouths that conform to the national standard or wear medical masks. They can resist most of the pollutants.
The correct way to wear the N95 mask is:
1. first pull the headband every 2-4 centimeters, hand through the mask headband, metal nose position forward.
2. put on the mask and stick to the face, put the top of the mask on the head, then pull the head over the head, place it behind the neck, and adjust it to a comfortable position.
3. hand fingertips along the nose bridge metal strip, from the center to the sides, slowly inward pressed until close to the bridge of the nose.
4. both hands try to mask the mask and carry out positive pressure and negative pressure test. (positive pressure test: both hands cover the mask and exhale vigorously. If the air is spilled from the edge of the mask, that is, if it is not properly worn, the headband and nose metal bar should be adjusted again. Negative pressure test: both hands cover the mask and exhale vigorously. The center of the cover will fall down, if air enters from the edge of the mask, that is to say, if it is not properly dressed, the headband and nose metal must be adjusted again.
