Disposable respirator masks have acquired increased attention as of late with the spread of the H1N1 flu virus, although they’ve long been used for other purposes including occupational safety. N95 refers to a National Institute for Occupational Safety and Health (NIOSH) rating that’s assigned to masks that meet a specified minimal customary for particle transmission. The N95 respirator mask is designed to filter as much as 95% of airborne particles 0.3 microns or larger which will otherwise directly enter the nose and mouth of the wearer. These masks may also be worn by individuals who have a contagious illness to prevent particles from leaving the nose and mouth of the wearer and placing others at risk. While such masks do not protect against particle transmission with one hundred% accuracy, they can be efficient in stopping the spread of infection.
N95 masks might be purchased with our without a valve to facilitate easier breathing. Optimum protection is achieved when the respirator mask suits snugly to the face, covering the nose and mouth without leaving open areas alongside the edge. Respirator masks must be fitted accurately to the wearer and never be obstructed by facial hair or jewelry. A poorly fitted respirator masks has greater potential to permit air particles to enter by means of gaps alongside the edges of the masks, providing decrease levels of protection against the inhalation or spread of particles than a well fitted one.
Respirator masks are widely used for occupational safety, and are notably frequent in industrial and health care facilities. Masks used within the workplace should be NIOSH-approved, which means they meet minimal requirements put forth by the National Institute for Occupational Safety and Health.
The intended function must be stored in mind when purchasing respirator masks. Completely different types are designed for specific functions and supply various levels of protection. One other consideration is whether the masks incorporates latex, an allergen for some people. Latex free N95 respirator masks are available, and might be marked as such.
