Covid-19: How Much Protection does the Mask Provide?

 Can masks help slow the spread of the coronavirus (SARS-CoV-2) that causes COVID-19? Yes, masks combined with other preventive measures (such as frequent hand washing and staying away from society) can help slow the spread of the virus.

So why is it not recommended to wear a mask at the beginning of the pandemic? At the time, experts did not know the extent to which people infected with COVID-19 could spread the virus before symptoms appeared. It is also not known that some people have COVID-19 but do not have any symptoms. Both groups may unknowingly spread the virus to other people.

These findings prompted public health organizations to make a face on the mask. The World Health Organization and the US Centers for Disease Control and Prevention now include masks in their recommendations to slow the spread of the virus. The CDC recommends that citizens cloth masks instead of requiring surgery and N95 masks by health care providers.

How do different types of masks work?

Face mask

Surgical masks, also called medical masks, are loose disposable masks that protect the wearer's nose and mouth from water droplets, splashes and sprays that may contain germs. Surgical masks can also filter out large particles in the air. Surgical masks can protect others by reducing exposure to saliva and respiratory secretions of mask wearers.

At present, the US Food and Drug Administration has not approved any type of surgical masks specifically for the prevention of coronavirus, but when there is no N95 mask, these masks may provide some protection.

N95 mask

The N95 mask is actually a respirator that provides more protection than disposable face mask china, because it can filter out large and small particles when the wearer inhales it. As the name suggests, the mask is designed to block 95% of very small particles. Some N95 masks have valves to make them easier to breathe. With this mask, unfiltered air is released when the wearer exhales.

Before using N95 gas masks in the workplace, healthcare providers must be trained and passed appropriate tests to confirm proper sealing. Like surgical masks, N95 masks should also be disposable. However, researchers are testing methods to disinfect N95 masks so that they can be reused.

Some N95 masks, and even some cloth masks, have one-way valves to make them easier to breathe. But because the valve releases unfiltered air when the wearer exhales, this mask does not prevent the wearer from spreading the virus. Therefore, their use is prohibited in some places.

Cloth mask

The gas mask is designed to capture the water droplets released when the wearer speaks, coughs or sneezes. Requiring everyone to wear a mask can help reduce the spread of the virus to people who have COVID-19 but are not aware of it.

When cloth face masks are widely used by people in public places, it is most likely to reduce the spread of the COVID-19 virus. Countries that needed masks in the early stages of a pandemic, testing, isolation, and distancing from society have successfully slowed the spread of the virus.

Although surgical masks and N95 masks may be in short supply and should be reserved for medical staff, cloth face masks and masks are easy to find or manufacture, and can be washed and reused.

The mask can be made of ordinary materials, such as a sheet made of tightly woven cotton. The instructions are easy to find online. Cloth masks should include multiple layers of fabric.

What Kind of Garbage Are Masks? Is It Safe After Incineration?

 Recently, the pneumonia epidemic caused by the new coronavirus has affected everyone's heart, and various issues about masks have also caused great concern. Especially masks used by infected patients.

How to deal with used masks? Disposable face mask manufacturer shares this article with you.

What kind of waste is the mask used by the infected person?

First of all, the medical waste generated by medical and health institutions is hazardous waste and cannot be discarded at will.

Medical waste is divided into five categories: infectious waste, pathological waste, traumatic waste, pharmaceutical waste, and chemical waste.

Infectious waste refers to medical waste that carries pathogenic microorganisms and has the risk of spreading infectious diseases.

The medical waste generated this time in response to the new coronavirus pneumonia is classified as infectious waste.

In addition to masks, what other infectious wastes are there?

Items contaminated by the patient’s blood, body fluids, and excreta, including: a cotton balls, cotton swabs, drainage slivers, gauze and various other dressings; b disposable sanitary products, disposable medical supplies and disposable medical devices; c Discarded bedclothes; d Other items contaminated by the patient's blood, body fluids, and excrement.

Domestic garbage produced by isolated patients with infectious diseases or patients with suspected infectious diseases admitted to medical institutions.

Pathogen's culture media, specimens, bacteria, and virus seeds.

Various discarded medical specimens.

Waste blood and serum.

Disposable medical supplies and disposable medical devices after use.

Is the waste generated in the hospital all medical waste?

Not all. For example, all kinds of glass or disposable plastic infusion bottles (bags) after use, and medical supplies that are not contaminated by the patient's blood, body fluids, or excreta are not classified as medical waste and do not need to be managed as medical waste. But this kind of waste cannot be used for the original purpose when it is recycled, and when used for other purposes, it should conform to the principle of not harming human health. Household waste generated in hospitals is generally not managed as medical waste.

Why should the generated hazardous waste be collected separately?

Separate collection is conducive to the treatment, disposal and resource utilization of hazardous waste, while reducing potential hazards to the environment. Mixing them without knowing the characteristics and ingredients of hazardous wastes will not only increase the amount of hazardous wastes treated and disposed of, but the mixing of hazardous wastes will also cause reactions such as explosions and release of toxic gases. These potential side reactions can not only cause environmental pollution, but also It will also make the handling and disposal of hazardous waste more difficult.

Is medical waste safe after incineration?

The incineration of medical waste will inevitably produce bottom slag and fly ash. The "National Catalogue of Hazardous Wastes" clearly stipulates that the fly ash generated during the disposal of hazardous waste incineration and pyrolysis is hazardous waste. Therefore, the fly ash generated by the incineration of medical waste is hazardous Waste; but the bottom slag needs to be identified to determine whether it is hazardous waste.

So what kind of garbage do used masks belong to?

Answer: The used masks need to be classified according to different situations.

The first category: If it is a mask used by ordinary healthy people, it is recommended to fold it neatly and put it in other trash cans.

The second category: If it is a mask used by people with infectious diseases or other physical diseases, it is recommended to sterilize the mask and wrap the discarded mask in a sealed bag, and then put it in a special medical trash can.

Why Should We Correctly Distinguish the Front and Back of a Mask?

 Disposable Face Mask China

Many people may think that the front and back are the same, as long as they wear Yanshi.  In fact, this is not the case. The front and back functions of disposable face mask china are different. Many masks use a three-layer design. The filter layer for filtering germs is located in the middle and the outer layer is a waterproof layer.  The inside is a water-absorbing layer.  If you wear it backwards, the water-absorbing layer will become a waterproof layer, and the waterproof layer will become a water-absorbing layer. This will cause the saliva to adhere to the surface of the mask, and the more it accumulates, it may wet the mask and make the mask lose is filtering function.

How to distinguish the front and back of the mask?

Disposable face mask manufacturer first teaches you to distinguish between upper and lower, "the one with the metal strip is on the top", because the metal strip can be used to adjust and fit the nose.

After the above is confirmed, let's judge which side is outside and which side is inside.

I have listed the characteristics of several common disposable masks, you can compare them to judge.

Judge by color

Generally, what we see is a blue medical surgical mask. The blue side is the outside, and the light (white) side is the inside (to the face).

Judge by printing

If there is a logo or brand name printed on the mask, it is easy to judge. The embossing of the logo or brand name is usually printed on the outside, and then you can know which side is outside by seeing whether the words are correct.

Judging by the direction of the folds

What if the mask you bought is pure white without any fonts?  It's okay, we have another ultimate method of judgment: look at the direction of the folds!

There are two types of folds in the mask:

Four folds

There is another type of mask that has four folds, which is better to judge. If you open it naturally, the middle one is convex, then this side is the outside.  In fact , it's easy to understand when you think about it. This allows our mouth and nose to have a certain amount of space to breathe.

After spreading, the direction of the upper two folds is upward, and the direction of the lower two folds is downward .

We can see the mask manual of Japan's three-dimensional brand to understand:

Three folds

The direction of the folds down is the outside:

Judge by metal bars

The protruding side of the metal strip is the outside:

The metal strip is relatively flat inside, which is also for the mask wearing experience:

to sum up

First, it can be judged by "color": "dark color is outside, light color is inside"; second, it can be judged by "printing", "printing is generally on the outside, and the words are positive."

If you buy a pure white mask without printing, you can judge by the "fold direction". If there are three folds, then the direction of the folds is down to the outside; if there are four folds, then the middle piece is convex outward after being stretched, which is the outside. In addition, after spreading, the direction of the top two folds is upward, and the direction of the bottom two folds is downward.

Finally, we can also distinguish the front and back through the "metal strip". The protruding side of the metal bar is the outside, and the flat side of the metal bar is the inside.

How does An Infrared Thermometer Work?

 Non Contact Thermometers

The world is now more familiar with the benefits of infrared technology and its usefulness in screening body temperature. Because infrared thermometers can read temperatures quickly and accurately without physical contact, more and more people are choosing infrared thermometers. With so many Workplace Safety equipment available, it is important to understand how this technology works and how best to use it.

Traditional mercury thermometers or digital thermometers are used by placing instruments inside objects, usually in the mouth under the tongue.Infrared thermometers, on the other hand, can measure temperature without touching anything (or your body) at all.When triggered, the light bounces off the object's surface and detects the radiation emanating from the object.The thermometer then extrapolates the temperature from this electrical radiation with surprising accuracy.ICI's non-contact thermometers, for example, have accuracy of ±0.3°C /±0.5°F.The accuracy of the thermometer is up to ±0.2°C /±0.4°F, depending on the external environment.It is important to note that these thermometers are measuring skin or surface temperature rather than internal temperature.High temperatures can be caused by a fever or by sitting outside on a hot day.

How does an infrared thermometer work?

Liquid thermometers, usually containing mercury, provide readings when liquid expands due to heat.The RTD digital thermometer contains a sensor that calculates temperature changes.Infrared thermometers are different in that they focus infrared light on an object to detect and measure energy, or radiation, from its surface. The detector then converts the amount of electricity generated into a temperature reading.

How do I use an infrared thermometer?

It is simple to use Non Contact Thermometers to get accurate measurements, but using it correctly is crucial to get the best results.Thermometers, for example, are important.When taking your temperature, the warmest part of your body is actually inside your eyes, not your forehead, as many people commonly think.This is where you should point the thermometer.Interesting fact: This is the most accurate position because the veins extend directly from the aorta of the heart to the inner corner of the eyes.To safely measure the internal CAN temperature, perform the following steps:

  • The patient should remain stable and not walk around.

  • The patient's eyes should be closed while the physician lines them.

  • Physician turns off the laser.

  • Patient reopens his or her eyes.

  • Physician takes the temperature.

Keep in mind that these steps need to be modified for visually impaired or deaf people.Another consideration is that these instruments should be used closely together.Reading the product guide to determine the ideal distance from an object is as important as the object's goal.The spot distance ratio between each device is different, which means that the position needs to be calculated to get an accurate reading of the target area.Too much area outside the desired target will affect the accuracy of the readings.For reference, infrared thermometers require the subject to stand 5 to 15 centimeters from the target.

Digital infrared thermometers, which provide accurate, stable temperature readings, are considered safe and effective.The portable power station can wear a laboratory coat and has a data recorder that can store up to 32 readings and can be set to sound an alarm when reading a specific temperature range.Infrared technology, from thermographs to thermometers, is an extremely effective, safe and useful tool for measuring skin temperature.While the advantages of infrared thermometers make the technology very attractive, it is important to remember that these tools are most effective in the hands of people with the right information and training.Contact us for more information about finding the best infrared products and technologies to meet your needs as well as training and educational opportunities.
