10 ANALYSIS OF THE POSSIBILITY OF DETERMINING THE MAXIMUM SAFE TIME FOR THE USE OF ESCAPE APPARATUS BASED ON EVACUATION DRILLS CARRIED OUT IN ACCORDANCE WITH THE GUIDELINES OF PN-EN 13794 This article attempts to analyse the possibility of determining the maximum safe time for the use of escape apparatus on the basis of underground escape drills carried out in accordance with the guidelines of the PN-EN 13794:2005 standard. The participants in the tests simulating an evacuation were four employees with different physical characteristics. The test participants were released on the route in one group, at a distance of approximately 2 m from each other. It was assumed that the test would be completed after a minimum of 60 minutes, or when the protective time of the escape apparatus had been exceeded if it proved to be shorter. During the evacuation simulation tests, pulse rate was randomly measured using wrist pulse oximeters and body temperature (skin surface and eardrum) was measured using electronic thermometers. All devices used in the tests exceeded the 60-minute protection time. The test was completed after approximately 84 minutes. None of the test subjects had reported any problems with the in- struments by this time. After the test, participants were interviewed about their state of well- being, comments on breathing comfort in the escape apparatus, other observations. The com- ments were recorded in the appropriate place on the questionnaires, which were filled in by the test participants. The survey and the results were analysed.
