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 together with occupational safety. N95 refers to a National Institute for Occupational Safety and Health (NIOSH) ranking that is assigned to masks that meet a specified minimum commonplace for particle transmission. The N95 respirator mask is designed to filter up to 95% of airborne particles 0.3 microns or bigger which will otherwise directly enter the nostril and mouth of the wearer. These masks might also be worn by individuals who have a contagious illness to forestall particles from leaving the nostril and mouth of the wearer and placing others at risk. While such masks don’t protect against particle transmission with 100% accuracy, they can be efficient in stopping the spread of infection.
N95 masks can be purchased with our with no valve to facilitate easier breathing. Optimal protection is achieved when the respirator masks matches snugly to the face, covering the nostril and mouth without leaving open areas along the edge. Respirator masks needs to be fitted correctly to the wearer and not be obstructed by facial hair or jewelry. A poorly fitted respirator mask has greater potential to allow air particles to enter through gaps alongside the perimeters of the mask, providing lower ranges of protection against the inhalation or spread of particles than a well fitted one.
Respirator masks are widely used for occupational safety, and are particularly widespread in industrial and health care facilities. Masks used in the workplace have to be NIOSH-approved, meaning they meet minimum requirements put forth by the National Institute for Occupational Safety and Health.
The intended function needs to be stored in mind when purchasing respirator masks. Different types are designed for particular functions and supply varying ranges of protection. One other consideration is whether or not the mask contains latex, an allergen for some people. Latex free N95 respirator masks are available, and might be marked as such.
