The KN95 masks and respirators are designed to meet the needs of people working in hazardous environments, such as power plants, manufacturing facilities, and factories. This respiratory protective equipment (RPE) is wo during all work activities. An KN95 mask is one of the most vital and critical pieces of equipment required for the protection of the wearer. A quality KN95 mask will protect a worker from inhaling fine dust particles, vapors, and other harmful particulate emissions.

The U.S. Food and Drug Administration (FDA) agree with this assessment, stating that KN95s provide a high level of protection against harmful substances and that long-term exposure does not cause negative health effects. However, both the FDA and American Society for Testing and Materials (ASTM) encourage caution when purchasing KN95 masks. In fact, both organizations recommend KN95 masks be restricted or banned for all occupations, while stating that they are not harmful.

As indicated in the previous section, both the FDA and ASTM recommend KN95 masks be restricted or banned for all occupations. But what about safety?

Avian influenza and the bird flu are transmittable through KN95s and other personal protective equipment wo by healthcare workers. Studies have shown that KN95s containing CpdB can contaminate a work environment with CpdB, a strain of the avian influenza. In addition, a study published by the NUREB organization in 2021 reported that KN95s may increase the risks of contacting pneumonia due to inhalation of KN95s aerosol. In some circumstances, the potential exposure to KN95s in the workplace has been shown to lead to the transmission of the novella.

In a report issued in May 2021, the Occupational Safety and Health Administration say KN95 masks should only be used by people working in certain industries. According to OSHA, these industries should be defined as those involving repetitive movements at very high speeds and with large parts that come in direct contact with the eyes, mouth or nose of the worker.
