Abstract

Guidelines to determine the real rate of protection for various types of respiratory system protective equipment

Project manager: Krzysztof Makowski M.Sc.

Project summary:

Basic purpose of this study was to develop the EU unified new research method aiming to determine the real rate of protection for various types of respiratory system protective equipment. This rate of protection was determined basing on survey in the workstation with the use of real aerosols; it was assumed that respiratory system protection equipment have been properly selected and used.
Within the research process the studies in questions were realised both in the workstation and in laboratory just to assess the reproducibility of the suggested method with the use of particle counter PortaCount.
The realised inter-laboratory studies showed the influence of the aerosol dimensional distribution and supply air flow rate to this survey effect.
It was stated that the research method with the use of particle counter PortaCount is the method of the so-called worse case i.e. that the obtained results of the real protection rate are the lowest in comparison to results obtained with the use of other research methods.
Due to the developed method there were tested real rate of protection for various types of respiratory masks with P2 and P3 filters as well as for equipment with forced air flow, directly in the workstations of grinder, welder and painter of steel structures.
