Analysis of Personal Protection Equipment for Upper Respiratory Tract to Prevent the Spread of COVID-19: Part II
Abstract
The coronavirus pandemic significantly affects the lives of families, employees, employers, or sole proprietors, and it is therefore necessary to prevent its spread by using appropriate protective equipment. The article discusses the possibilities of protection against various forms of harmful particles, including the highly infectious virus SARS-CoV-2 using face protection respectively respiratory protection.

Introduction
Clinicians and experts in the field of public health recommend preventive measures, including use of respiratory protective devices, to reduce the disease caused by infection with severe acute respiratory syndrome coronavirus 2 (known as SARSCoV-2). It is thought that SARS-CoV-2 is spread primarily through contact and large respiratory droplets, but evidence also indicates potential transmission by fine respiratory aerosols located in the surrounding environment. [1 – 3] There are available several types of face masks and the respiratory protective equipment to be used in hazardous work environments, including environments contaminated by a new virus SARS-CoV-2.
Conclusion
Based on previous experience and knowledge, SARS-CoV-2 has been shown to spread primarily through close personal contact with symptomatic individuals and also through contaminated surfaces with infectious droplets and subsequent transmission of these droplets to the mucous membranes of the eyes, nose or mouth. It is assumed that the transmission of the virus occurs through the very small air particles.
At present, several PPE are available on the market. PPE is used to protect health as well as the respiratory tract in the work environment. These devices have also found application in reducing the risk of transmitting COVID-19, especially in the front-line sectors. In an effort to eliminate this infection, a number of countries have engaged in research of the new materials for the production of filters as well as the types and shapes of protective face masks.
