Mouthpiece: Everything You Need To Know About Them
Mouthpieces are protective equipment that can be used for various purposes. They protect, for example, against exposure to pollutants through the respiratory tract. They are made of a filtering material and they usually have a clip or nose adapter and rubber bands or fastening cords.
Some sanitary napkins have exhalation valves. These valves make it easier to pull the weight, while preventing condensation. These are intended for long-term use.
Different types of sanitary napkins
There are two types of mouthpieces:
Surgical bandages
These bandages protect other people. This is because they filter the particles when you breathe and they prevent them from reaching out of the mask.
High-performance FFP mouthpieces
This type of mask protects the person wearing it. It filters the particles in the environment so that the person does not inhale them.
They are available in different sizes depending on their design. They can also be conical, horizontal or vertical. They are divided into classes (1, 2 and 3) according to their efficiency. The class type depends on how well they filter the pollutants into the environment.
- FFP1: 78% filtration efficiency, environmental concentrations up to 4 TLV (maximum permissible concentration)
- FPP2 : 92% filtration efficiency, environmental concentrations up to 12 TLV (maximum permissible concentration)
- FFP3 : 98% filtration efficiency, environmental concentrations up to 50 TLV (maximum permissible concentration)
How to wear a face mask?
The best sanitary napkin depends on the risk factors. However, it is important to wash your hands with soap and water thoroughly both before and after use. Put on the handkerchief before entering a contaminated area and do not remove it again until you are away from the area again. Also, make sure that the mouthpiece is properly seated so that you are properly protected.
It is also important to replace the mouthpiece after use, as it may have become wet or damaged. Furthermore, it is a good idea to change the mouthpiece if you inhale a lot, as moisture can accumulate and then the mouthpiece can not filter properly.
What type to use?
You need to change bandages when changing activities or going from one type of environment to the next.
FPP2 sanitary napkins should fit the entire surface of the face, covering the nose and mouth completely to protect the mucous membranes. Use this type in connection with the isolation measures as well as the precautions regarding infected people. FFP3 masks are intended for when there is a risk of exposure.
How to take a bandage on and off
It is important to know how to take the mouthpiece off and on so that one can protect oneself properly. However, it is also important to know how to take it off again. If you do not do it properly, you can become infected.
Application
The mouthpiece must be put on before entering a contaminated environment. Follow these steps:
1. Wash your hands and check the expiration date of the mouthpiece. There must be nothing wrong with that.
2. Now you can put on the mouthpiece.
3. Make sure it is seated correctly so that you protect yourself. If you wear glasses, take them off so you can put on the mouthpiece and adjust it. Then you can put on glasses again.
How to make it sit right?
1. Hold the mouthpiece with both hands and leave the nose clip at the top. Then shape the clip by folding it gently in the middle and open the mouthpiece by pulling on the edges of the bottom.
2. Place the bandage under your chin and pass the two elastics over your head.
3. Pass the lower elastic under your ears and the upper elastic over your head.
4. Finally, shape the nose clip with both hands to fit the shape of your nose.
Removal
You must not remove the bandage until you have left the contaminated area. Then be sure to put it directly in the trash, after which you should wash your hands thoroughly with soap and water.
Conclusion
As you can see, there are different types of mouthpieces that can protect us and filter the harmful particles in the environment. Therefore, it is important that you choose the right type and put it on properly. It is far from all sanitary napkins that are equally useful, and unfortunately there are some that are even counterproductive.
