N95 mask, often abbreviated as N95 mask, is a filter-fitted particulate-filter respirator that meets the federal U.S. National Institute for Occupational Safety and Health (NHS) classification of workplace safety, which means that it filters at least 95 percent of airborne particulates. N95 masks are used in various environments such as the workplace, hospitals, construction sites, and schools. They can also be used for protection during activities involving heavy contact with particles. N95 mask are made of a hard durable material such as non-woven polypropylene.
The safety guidelines and requirements to meet by the N95 mask
N95 mask must meet the requirements of the Occupational Safety & Health Administration (OSHA). N95 mask should be easy to put on, easy to remove, free of facial hair, comfortable, and easy to clean. N95 mask is usually prescribed by an occupational therapist or doctor when the employee has allergies or other conditions that may be caused or exacerbated by dust, pollen, or airborne particles. It is important to note that N95 mask is not recommended for employees who smoke, have a pacemaker, are pregnant, or have a condition such as lung cancer, which can pose health risks during exposure. If you work in any of these fields, you will most likely need to use N95 mask while working.
The protective features of N95 mask are divided into two parts. The first part is the face shield, which is usually oval or teardrop-shaped and made from clear plastic or vinyl. This part takes in allergens, irritants, and any particles in the air that the wearer could become exposed to. The face shield has an airtight seal, which helps keep the wearer’s breathe free from contamination and irritation.
The facepiece parts of the masks
The second part of N95 mask is its filtering facepiece. These are the units that cover the face and nose in order to protect the wearer’s eyes. The filtering face pieces are made from either polystyrene or polycarbonate, and they can be found in disposable or permanent types. They are often found in healthcare settings where the occupants can be at higher risk for respiratory infections. In such situations, the N95 masks and respirators are permanently attached, while disposable filters can be easily removed.
N95 mask works with N95 filtering facepiece. These protective gears attach to the mask, covering the wearer’s nose, mouth, and eyes. They prevent particles from entering these areas. In fact, they are so effective that these masks are often compared to paper filters. Since particles are not able to penetrate through the filter to reach the eyes or the skin, the pores of the mask remain intact and do not become blocked.
Why disposable masks are not a good choice?
While disposable masks may offer little protection against particulates, they do offer protection against certain gases. For example, the gas carbon monoxide (CO), which causes carbon dust, can pass through small gaps in some kinds of N95 filters. Thus, it is important for the filtration of CO in these masks have microns of a large size. This ensures that the tiny airborne particles are trapped. microns are defined as 3 micrometers high and shorter.
Cloth masks, on the other hand, allow the air to circulate freely. Therefore, when bacteria or other foreign particles are breathed in, they are easily dislodged by the action of the circulating air. These cloth masks are less effective in containing bacteria or foreign particles than the N95 masks. However, since these masks do not offer complete filtration and air purification, they are not appropriate for those who have breathing difficulties or are allergic to them.
