Face Masks During The COVID-19 Pandemic
During the COVID-19 pandemic, face masks or coverings, including N95 respirator, N95, FFP standards#FFP2 mask, FFP2, surgical mask, surgical, and Cloth face mask, cloth masks, have been employed as public and personal health control measures against the spread of SARS-CoV-2, the virus that causes COVID-19. In community and healthcare settings, the use of face masks is intended as Source control (respiratory disease), source control to limit Transmission of COVID-19, transmission of the virus and for personal protection to prevent infection. Properly worn masks both limit the respiratory droplets and Airborne transmission, aerosols spread by infected individuals and help protect healthy individuals from infection. Reviews of various kinds of scientific studies have concluded that masking is effective in protecting the individual against COVID-19. Various case–control study, case-control and population-based studies have also shown that increased levels of masking in a communit ...

Shortages Related To The COVID-19 Pandemic
The landscape of shortages changed dramatically over the course of the COVID-19 pandemic. Initially, extreme shortages emerged in the equipment needed to protect healthcare workers, diagnostic testing, equipment and staffing to provide care to seriously ill patients, and basic consumer goods disrupted by panic buying. Many commercial and governmental operations curtailed or suspended operations, leading to shortages across "non-essential" services. For example, many health care providers stopped providing some surgeries, screenings, and oncology treatments. In some cases, governmental decision making created shortages, such as when the CDC prohibited the use of any diagnostic test other than the one it created. One response was to improvise around shortages, producing supplies ranging from cloth masks to diagnostic tests to ventilators in home workshops, university laboratories, and rapidly repurposed factories. As these initial shortages were gradually remedied throughout 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goggles
Goggles, or safety glasses, are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, and in the sport of swimming. Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription goggles for those with vision problems. History The Inuit and Yupik carved snow goggles from the antlers of caribou, wood, and shell to help prevent snow blindness. The goggles were curved to fit the user's face and had a large groove cut in the back to allow for the nose. A long thin slit was cut through the goggles to allow in a small amount of light, diminishing subsequent ultraviolet rays. The goggles were held to the head by a cord made of caribou sinew. In the ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Face Shield
A face shield, an item of personal protective equipment, aims to protect the wearer's entire face (or part of it) from hazards such as Projectile, flying objects and road debris, chemical splashes (in laboratory, laboratories or in Industry (economics), industry), or potentially Infection, infectious materials (in Medicine, medical and laboratory environments). Applications Medical In Medicine, medical applications the device is used to protect a medical professional during a procedure that might expose them to blood or other potentially infectious fluids or aerosols. An example is the use of a Pocket mask, CPR mask while performing Mouth-to-mouth resuscitation, rescue breathing or Cardiopulmonary resuscitation, CPR. Another example is the use of face shields to reduce the likelihood of inhaling potentially infectious bioaerosols.

Personal Protective Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elastomeric Respirator
Elastomeric respirators, also called reusable air-purifying respirators, seal to the face with elastomeric material, which may be a Natural rubber, natural or synthetic rubber. They are generally reusable. Full-face versions of elastomeric respirators seal better and protect the eyes. Elastomeric respirators consist of a reusable mask that seals to the face, with exchangeable filters. Elastomeric respirators can be used with chemical cartridge filters that remove gases, Mechanical filter (respirator), mechanical filters that retain particulate matter, or both. As particulate filters, they are comparable (or, due to the quality and error-tolerance of the elastomeric seal, possibly superior) to filtering facepiece respirators such as most ''disposable'' N95 respirators and FFP masks. Elastomeric air-purifying respirators are designed to be safely reused for years. Provided the cartridge integrity and filter have not been compromised, current practice shows that the filters could b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Respirator
A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres including lead, lead fumes, vapors, gases and particulate matter such as dusts and airborne pathogens such as viruses. There are two main categories of respirators: the ''air-purifying respirator'', in which respirable air is obtained by filtering a contaminated atmosphere, and the ''air-supplied respirator'', in which an alternate supply of breathable air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants. Air-purifying respirators range from relatively inexpensive, single-use, disposable face masks, known as filtering facepiece respirators, reusable models with replaceable cartridges called elastomeric respirators, to powered air-purifying respirators (PAPR), which use a pump or fan to constantly move air through a filter and supply purified air into a mask, helmet or hood.

Filtering Facepiece Respirator
Mechanical filters, a part of particulate respirators, are a class of filter for air-purifying respirators that mechanically stops particulates from reaching the wearer's nose and mouth. They come in multiple physical forms. Mechanism of operation Mechanical filter respirators retain particulate matter such as dust created during woodworking or metal processing, when contaminated air is passed through the filter material. Wool is still used today as a filter, along with plastic, glass, cellulose, and combinations of two or more of these materials. Since the filters cannot be cleaned and reused and have a limited lifespan, cost and disposability are key factors. Single-use, disposable and replaceable-cartridge models exist. Mechanical filters remove contaminants from air in the following ways: # by ''interception'' when particles following a line of flow in the airstream come within one radius of a fiber and adhere to it; # by ''impaction'', when larger particles unable to ...

FFP Respirator
The European respirator standards refer to the filtering classification by EN 149, EN 14683, and EN 143, all European standards of testing and marking requirements for respirators. FFP standard masks (where FFP stands for filtering facepiece) cover the nose, mouth and chin and may have inhalation and/or exhalation valves. EN 149 defines three classes of such particle half masks, called FFP1, FFP2 and FFP3, according to their filtering efficiency. It also classifies masks into "single shift use only" (not re-usable, marked NR) or "re-usable (more than one shift)" (marked R), while an additional marking letter D indicates that a mask has passed an optional clogging test using dolomite dust. Such mechanical filter respirators protect against the inhalation of particulates such as dust particles, droplets, and aerosols. EN 14683 defines respirators for use in medical settings, while European standard EN 143 defines the 'P' classes of particle filters that can be attached to a face mask ...
