Different types and standards.
Therefore, the masks used must be adjusted to the intensity level of certain activities, including to treat the current outbreak of the Covid-19 coronavirus.
The following are the types and classifications of masks that the general public should know based on the guidance of the National Disaster Management Agency (BNPB)
Cloth masks can be used to prevent transmission while anticipating the scarcity of masks that occur in markets such as pharmacies and health stores. Cloth masks made should have 3 (three) layers, namely a waterproof non-woven layer (front), fusion blown microfiber non-woven fabric (center), and ordinary non-woven fabric (back).
Cloth masks must be washed and can be used many times. The material used for the cloth masks is cotton, scarf, etc.
The use of cloth masks can be used to:
For the general public in good health, this type of mask can be used in public places and other facilities, keeping a safe distance of 1-2 meters. However, if the community has activities classified as dangerous (for example, manipulating the bodies of Covid-19, etc.), it is not recommended to use cloth masks, but should use other types of masks and supporting PPE.
Especially for medical personnel, cloth masks are not recommended as PPE (Personal Protective Equipment) for high severity because approximately 40% -90% of particles can penetrate cloth masks for medical personnel. Cloth masks should only be used as a last resort if surgical masks or N95 masks are no longer available.
Even so, the use of cloth masks by medical personnel should ideally be combined with protectors.
face covering the entire front and sides of the face.
- 2-layer surgical mask or have another name 2-layer surgical mask.
2-layer surgical mask alias urgical The 2-layer mask only consists of 2 layers (layers), that is, the outer layer and the inner layer without the intermediate layer that functions as a filter.
Because it does not have a filter layer in the middle between the waterproof outer layer and the inner layer that is in direct contact with the skin, this type of mask is less effective at filtering out droplets or splashes from the mouth and nose. user when coughing or sneezing.
Thus, this type of mask is only recommended for daily use in the community that does not show flu or flu symptoms accompanied by coughs, sneezes, runny nose, fever, sore throat. Because it is easy to penetrate, the use of this mask by medical personnel in health care facilities is not recommended, especially not to treat patients exposed to the Covid-19 coronavirus.
- 3-layer surgical mask or 3-layer surgical mask
Surgical masks have three layers, namely the outer layer of fabric without waterproof mat, the inner layer which is a high-density filter layer and the inner layer that adheres directly to the skin that functions as an absorbent liquid coming out of the user when coughing or sneezing.
Because it has this filter layer, surgical masks are effective at filtering out droplets that come out of the user when coughing or sneezing. However, this layer is not a respiratory protection barrier because it cannot protect the user from inhaling smaller particles in the air.
Thus, this mask is recommended for people who show flu or flu symptoms such as cough, sneezing, runny nose, fever, sore throat. This mask can also be used by medical personnel in health centers.
- N95 mask (or equivalent)
N95 masks are the most frequently discussed masks and are a group of disposable filter respirator (FFR) masks. This group of mask types has the advantage of not only protecting the wearer from exposure to droplet-sized fluids, but also liquids to aerosols.
This type of mask also has an airtight face seal adjustment that helps the user avoid exposure to aerosols as long as they ensure that the seal adjustment is installed correctly.
The filter mask respirator (FFR) types equivalent to N95 are FFP2 (EN 149-2001, Europe), KN95 (GB2626-2006, China), P2 (US / NZA) 1716: 2012, Australia / New Zealand) , KF94 (KMOEL-2017-64, Korea), DS (JMHLW Notification 214.2018, Japan).
This group of masks is especially recommended for healthcare professionals who must be in direct contact to directly manage cases with high infection rates, such as positive patients infected with the Covid-19 virus.
- Reusable mask respirator
This type of mask has a higher filter effectiveness compared to N95, although it depends on the filter used. Because it has a greater filtering capacity than the N95, this type of mask can also filter to form gas.
This type of mask is recommended and is commonly used for jobs that have a high risk of exposure to harmful gases. This type of mask can be used many times as long as the face seal is not damaged and must be properly cleaned with disinfectant before reuse.
