Recently, the epidemic situation has been serious. Many friends have worn masks, but the way to wear masks may not be standardized and correct. Do you know the correct way to wear ffp3 mask? This article will briefly talk about the correct way to wear a mask.
This passage is going to talk about the followings of how to wear ffp3 mask:
What is ffp3 mask?
Method of choosing
When can I take off my mask?
Replace the mask
Ffp3 masks refer to masks that meet the European (CEEN149:2001) standard. The European standards for protective masks are divided into three levels: FFP1, FFP2, and FFP3. The difference from the American standard is that its detection flow rate is 95L/min and DOP oil is used to generate dust.
Aerosol filtration rate: not less than 99%.
Internal leakage rate: maximum 2%
Ffp3 mask is the most filter in FFP mask. It can prevent very fine particles such as asbestos and ceramics. It cannot prevent gases, especially nitrogen oxides.
First: The dust-proof efficiency of the mask should be high. The dust suppression efficiency of a mask is based on its dust suppression efficiency for fine dust, especially for respirable dust below 5μm. General gauze masks, the dust blocking principle is mechanical filtration, that is, when dust hits the gauze, it passes through a layer of barriers, blocking some large particles of dust in the gauze. However, fine dust, especially dust less than 5μm, will pass through the mesh of the gauze and enter the respiratory system. There are some anti-particulate masks on the market. The filter material is composed of fibers charged with permanent static electricity. Respirable dust less than 5μm will be attracted by static electricity and adsorbed on the filter material when passing through this filter material. It really plays a role of dust blocking.
Second: The degree of closeness between the mask and the face shape is better. When the mask is not close to the human face, the dust in the air will enter the respiratory tract from the gaps around the mask. Therefore, people should choose an anti-particle mask that suits their face shape and wear an anti-particle mask correctly.
Third: Wear comfortably, including low breathing resistance, light weight, sanitary wear, and convenient maintenance, such as wearing an arched anti-particle mask.
Wear a mask until you finish your trip, errand, or shift. You can remove them when you are away from others, or you can remove them on the way home. Don't forget to bring a mask for cleaning. If you wait to take off the mask after you go home, it may be easier to put it directly in the laundry.
Replace the mask in time in the following situations:
When the respiratory impedance increases significantly
When the mask is broken or damaged
When the mask and the face cannot be closely attached
The mask is contaminated (for example, when it is stained with foreign objects such as blood stains or droplets)
The mask has been contaminated (used in individual wards or in contact with patients)
If the mask contains activated carbon, if there is an odor in the mask
When the mask has been used for longer than the recommended time
