Make America great again, they say...
Such protective equipment can make you dangerous to others.
Sometimes protective fabric masks are equipped with a special valve. In this case, the mask works like this - you inhale air through filters and exhale it through a one-way valve. Thus, warm air comes out from under the mask faster, it becomes easier to breathe, the mask is easier to wear, and glasses will not fog up.
We put on masks for two reasons. Firstly, we hope that they will protect us from COVID-19 (however, disputes are still underway regarding the effectiveness of masks). Secondly, more importantly, the mask does not allow us to infect others, if we are sick and do not suspect it.
The valve allows free passage of air as it exhales. This means that an infected person will spread particles of the virus around him as if he weren’t wearing any protection at all.
The U.S. Centers for Disease Control and Prevention does not recommend using masks and respirators with valves to prevent infection with this disease.
Such protection can be worn in conditions of smog, dust and smoke - for example, at a construction site or factory where harmful particles are floating in the air. But the mask with the valve will not stop the spread of the virus.
Transparent mask, with a view to the smile, the new fashion in Italy. For whom it is extremely useful
People's inventiveness has never disappointed. As the face mask has become an indispensable accessory all over the world, manufacturers have adapted and found new ways to make it more efficient, more beautiful, more friendly. Thus, transparent protective masks appeared, with a view to the smile. For certain categories of people they are extremely useful.
An Italian company has started producing transparent surgical masks that seem to be in high demand. The center part of the mask is made of polyurethane, well sealed with the rest of the material, can be washed by hand and reused.
These models of masks are useful primarily for people with hearing impairments, which are based on sign language. Restaurant owners also find it extremely useful for waiters who want to show a smiling face. Beauty salon staff and anyone working with the public can use such masks. But not only. And ladies who care about their image and do not want to give up makeup, lipstick, can use such a mask.
"Transparent masks are for everyone. Anyone can use them to have an easier communication, not only through words, but also through gestures, facial expressions, lip movements ", said Dorina Marini, the representative of the factory in Italy, quoted by PRO TV. The cost of such a mask is almost $ 7, and the manufacturer has already had to honor 15,000 orders.
You can’t find a protective mask in pharmacies or it’s price is hitting you? If you want to protect yourself, a mask to cover the mouth and nose can be made at home. However, a textile mask is not as effective as a surgical one, but it is very useful during this period. If you do not know how to sew, with a scissors, a piece of material and two hair bands you can make a protective mask.
The American Center for Disease Prevention and Control (CDC) has reverted to previous recommendations made in the context of the pandemic and currently believes that wearing simple masks in textiles could slow the spread of coronavirus.
Instructions for making your home a protective mask
The material used should be cut in such a way that it is wide and long enough to cover your nose and mouth
The material should be bent at length.
At each end tie a hair elastic.
Bring the ends tied inwards.
Arrange the mask near the mouth and nose and fasten the elastics behind the ears.
It is important to know:
•Simple surgical masks have a much higher protection than textiles.
• Even if we wear a mask, we must keep at least 3 steps away from the others.
•We disinfect / wash our hands before and after putting on our masks and do not touch them when wearing them.
•After each use, the textile masks must be washed: a washing machine is sufficient.
•Such textile masks are especially useful in places where physical distance is difficult to maintain: queues, small shops or pharmacies, crowded means of transport, etc.
• This recommendation can be used as an additional public health measure.
• The CDC emphasizes that textile masks should not be worn by children under 2 years of age or by persons with respiratory problems.
• The materials from which the textile masks are made do not sufficiently protect the hospital environment.
•The World Health Organization strongly recommends wearing surgical masks or special protective masks in the hospital environment.
The face shield is very effective. It does not make breathing difficult, and glasses do not fog up. According to scientists from the University of Iowa, the face shield reduces the risk of contracting COVID-19 by 96% if an infected person coughs in your face. And even if you contact the patient for 30 minutes, the shield will protect you by 80%.
For comparison: the effectiveness of disposable medical masks ranges from 60 to 75%. For homemade fabric masks, this number varies depending on the material, from 40 to 90%, and for a respirator reaches 95%.
The face shield does not need to be washed and wait until it dries, it can be disinfected with soap and water or a 70% solution of alcohol, as recommended by use of personal protective equipment for coronavirus disease (COVID-19) and considerations regarding the situation of their acute shortage of WHO. And it is reusable, unlike surgical masks. Yes, and it interferes with touching your face.
For optimal protection, the visor should completely cover your chin and forehead, so choose the right size. Ideally, the shield should be worn with the mask. So you cover both your mouth and face skin and eyes.
If you do not know where to buy such a shield, you can make it yourself with a simple instruction.
Disposable masks have invaded the beaches of Hong Kong where, for several months, residents have been covering their faces to protect themselves from the new coronavirus.
According to environmental associations, these masks add to the already worrying amounts of plastic waste floating in Hong Kong's waters, writes Agerpres.
"The disposable mask is just another weight we leave to future generations," said Gary Stokes, co-founder of OceansAsia.
Shortly before the pandemic broke out, the Hong Kong environmental organization launched a one-year study on waste and microplastics found on one of the country's most remote and uninhabited islands.
The five most commonly found items were bottles, polystyrene packaging, lighters, disposable cutlery and plastic straw.
Currently, disposable masks float on the surface of the sea, along the beaches and the coast.
Recently, environmentalists identified and collected 70 masks within a radius of 100 meters. A week later, another 30 masks were found.
"Since people started wearing masks, the consequences of this phenomenon are now visible on the beaches," Stokes said.
Hong Kong's nearly 7.5 million people produce six million tons of waste each year, of which only about 30% is recycled.
