Coronavirus is an RNA virus that causes disease in birds and mammals, and in human beings, it causes respiratory ailment, which ends up from mild to lethal. The virus is known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease it causes is named coronavirus disease 2019 (COVID-19).
Masks have been the most mandatory accessory ever since the pandemic hit the world, though once restricted to several specific occupations. The demand for these respiratory protection products has skyrocketed by all means.
The situation continues to evolve on a nearly daily basis, and different governments have become anxious about the condition that could lead to a potential shortage of N95 masks. Has it continued to rage since the Pandemic hit?
N95 mask :
N95 masks are a type of protection that protects the person from airborne particles and liquids contaminating the face. The new government warning is for the N95 masks that come with the exhalation valves. N95 masks are worn mainly by healthcare staff and are considered to provide the highest degree of protection against airborne infections but do have limitations. N95 masks remove about 95% of the particles smaller than 300 nanometres (1 nm is a billionth part of a meter). SARS-CoV-2, the virus that causes Covid-19, however, is 65-125 nm in size.
The Function of Exhalation Valve in an N95 Mask:
The valve or raised plastic gasket used in some N95 mask models effectively filters the person’s inhaled air and blocks the entry of pathogens suspended in the air. The valves make it easier to exhale than conventional masks, avoid moisture, minimize heat and build up carbon dioxide within the mask.
N95 vs Valve Respirators :
The Ministry of Health has reported that N95 masks with valve respirators do not prevent the virus from escaping the mask. The valve is simply a ‘one-way valve’ that only covers the person who wears it and does not filter out the aerosols. As a result, in a closed environment, people around the carrier are at greater risk of possible exposure to the virus. Asymptomatic transmission occurs when a person who has no symptoms of Covid-19—such as fever, body ache, cough, etc.—transmits the infection to another person.
Recommendation of Health Minister for N95 mask :
- The Ministry of Health has advised the public to use home-made face masks or masks made of fabric, preferably cotton, which can easily be tied or attached to the nose and mouth. The government also published a comprehensive manual on how to make home-made masks and recommended it to everyone.
- In its June updated recommendations, the World Health Organization proposed that everyone should wear cloth (non-medical) masks in public. Fabric masks should have at least three layers of various materials. Any person with symptoms of Covid-19 should wear a medical mask.
- Many N95 Respirators are manufactured for use in construction and other industrial-type jobs that expose workers to dust and small particles. They are certified by the National Personal Protective Technology Laboratory (NPPTL) in the National Institute for Occupational Safety and Health (NIOSH), which is part of the Centers for Disease Control and Prevention (CDC).
- However, some N95 respirators are intended for use in health care environments. Specifically, single-use, disposable respiratory protection devices are used and worn by health care personnel during procedures to protect both the patient and health care personnel from the transmission of microorganisms, body fluids, and particulate matter.
- People with chronic respiratory, cardiac, or other medical conditions that make breathing difficult should consult with their health care provider before using the N95 Respirator because the Respirator can make it more difficult for a person to breathe.
- Some models have exhalation valves that can make breathing easy and help minimize heat build-up. Notice that N95 exhalation valve respirators should not use when sterile conditions are required.
- All FDA-cleared N95 respirators are listed as one-time used, disposable products. If your respirators is harmed, or if breathing becomes difficult, you should remove the mask, discard it properly. To dispose of your N95 Respirator safely, place it in a plastic bag and place it in a garbage bag. Clean your face after handling the used Respirator. To safely dispose of your N95 Respirator, place it in a plastic bag and place it in the garbage. After handling the used Respirator, wash your face.
- N95 Respirators are not for children or people with facial hair. Since no properly fitting for children and people with facial hair, the N95 Respirator does not offer complete safety.
Look for one that has high-quality steel tips when buying your Respirator. These are necessary because they will make sure your respiratory mask stays on your face when you’re working. If you use a cheap product, you will find that the tips are detached from the breathing mask, which means that you will need to buy another one to keep your face protected. Now you will tell if the breathing mask you’re wearing is approved or not. Also, you can test at your homes by doing some home remedies. A standard N95 breathing mask is approved by the National Institute for Occupational Safety and Health (NIOSH).
The Centers for Disease Control and Prevention (CDC) does not recommend that the general public use N95 respirators to protect themselves from respiratory diseases, including coronavirus (COVID-19). These are essential resources that must continue to be reserved for health care staff and other first responders, as recommended in the latest CDC guidelines.
The CDC suggests that the general public use clear cloth face coverings to slow the spread of the virus in public environments since this will protect those who may have the virus and do not know how to pass it on to others.
