Developing a method and a stand for testing inward leakage with the use of sulphur hexafluoride for a respiratory protective device

Project manager: Krzysztof Makowski M.Sc.

Project summary:

Than main aim of the task was to build a test stand and to develop a method of testing inward leakage for the face piece of a respiratory protective device with a gas medium as well as to assess the possibility of eliminating the human factor from testing leakage. Within the task: - principles were developed for a method of testing inward leakage for a respiratory protective device with sulphur hexafluoride, a test stand was built - anthropometric measurements of the face were conducted for a test group from Poland to compare the dimensions of the face in the population of Poland with the results obtained by NIOSH (USA) for the multinational population of the USA - a series tests of inward leakage was done on selected types of equipment and selected groups of participants to assess repeatability and reproducibility of the obtained results of measurements and to determine if gender influences results of leakage measurements - a testing procedure was developed for establishing inward leakage with SF6 for the face pieces of respiratory protective devices; it was introduced into the system of assessing compliance - information materials for CIOP-PIB`s website were developed.
