Selected Respiratory Protective Devices: Respirators and Significance of Some Markings

Abstract

Currently, setting the obligation to use respiratory protective equipment with a level of protection of at least FFP2 in public transport and commercial and shopping centers are considered within the European Union. Many new products appeared on the European market within these specifications, and many symbols have been used. The paper deals with the meaning of selected respiratory protection based on respirators symbols and markings (which appeared massively, especially after the pandemic situation in the spring of 2020), these symbols not being uniformly understood and well communicated. We also mention and discuss some of the problems related to setting the conditions of public procurement, which affect respirators. Thus, this review is an “informative guide” in facilitating the understanding and use of full knowledge of the most appropriate respiratory protective devices in various situations.

Acute Effects of Air Pollution on Ischemic Heart Disease Hospitalizations: A Population-Based Time-Series Study in Wuhan, China, 2017–2018

“…For the individual, we can protect ourselves from air pollution by reducing exposure and decreasing the impact [ 56 ]. On the one hand, individuals can reduce unnecessary exposure by wearing masks and using household clean energy [ 57 ].

The face behind the Covid-19 mask — A comprehensive review

“…Hence, users are discouraged to wear moisture (sweat) rich facemasks ( Bungău et al, 2019 ). Most manufacturers address this issue by covering the filter with activated carbon, which absorbs moisture and so increases the life and efficacy of the filter ( Otrisal et al, 2021 ). This type of ultra-fine fibre significantly improves filtering efficiency while lowering permeability to near-zero levels ( Subramanian et al, 2009 ).…”
