Breathing Air Purification for Hyperbaric Purposes, Part II

Abstract

Determining the efficiency of breathing air purification for hyperbaric purposes with the use of filtration systems is of a crucial importance. However, when the Polish Navy took samples of breathing air from their own filtration plant for quality purposes, these were found to not meet the required standard. The identification of this problem imposed the need to undertake actions aimed at the elimination of the identified disruptions in the process of breathing air production, with the objective of assuring its proper quality. This study presents the results of the initial tests on the air supply sources utilised by the Polish Navy, which were carried out for the purpose of setting a proper direction of future works and implementing corrective measures in order to optimise the breathing air production process. The obtained test results will be used in a subsequent publication devoted to the assessment of the level of efficiency of air purification with the use of a multifaceted approach consisting in the utilisation of various types of air supply sources and different configurations of purification systems.

Evaluation of the Impact of Breathing Air Contamination on Safe Performance of Hyperbaric Exposure

Abstract

The evaluation of the impact of contamination in breathing air intended for hyperbaric purposes is essential both for practical and theoretical reasons. The quality of breathing air and the breathing mixes obtained on its basis is of crucial importance with regard to divers’ safety in the course of underwater works. The existing contaminants, as well as substandard quality gases have an adverse impact on divers’ health and life, both in terms of the physiological impact on the body, and fire hazards in hyperbaric complexes. In the process of breathing air production we deal with a few sources of potential contaminants stemming from technical measures. The human body is also responsible for the release of contaminants in hyperbaric conditions. The article presents the above issues and provides insight into existing threats.

Effectiveness evaluation of sources of supply and systems filter in production process of breathing air

Abstract

The determination of how efficiently filtration systems used for the production of breathing air used in hyperbaric environments are operating is significant both from theoretical and practical points of view. The quality of breathing air and the breathing mixes based on air is crucial with regard to divers' safety. Paradoxically, a change in regulations regarding quality requirements for breathing mixes has imposed the necessity to verify both the technical equipment and laboratory procedures used in their production and verification. The following material, which is a continuation of previous publications, presents results of the conducted research along with the evaluation of effectiveness of the filtration systems used by the Polish Navy.

Analysis of the Breathing Air Production Process for Hyperbaric Purposes

Abstract

The quality of breathing air plays a key role in the safety of divers and hyperbaric facilities. Paradoxically, the change of regulations concerning quality requirements for breathing mixes has imposed the need for verification of the technical and laboratory bases used in their production and control. This article presents the results of research related to the rationalisation of the process of production and supply of breathing air for the purposes of hyperbaric oxygenation. The work was carried out using the SixSigma method.
