COMPARATIVE ANALYSIS OF THE ACTIVITY OF GAS SMOKE PROTECTORS DIFFERENT AGE GROUPS

Abstract

The conducted analysis showed that an important and unresolved part of the problem of increasing the efficiency of liquidation of emergency situations related to the operational activities of firefighters and rescuers in an environment unsuitable for breathing is the lack of information about how the age of the gas smoke protection device affects the indicators characterizing the results, in that in this case physiological, performance of professionally important tasks. Comparative experimental studies of the results of the activities of gas and smoke rescuers of two age groups in compressed air apparatus (ASP) in a container-type mobile simulator manufactured by MAW GmbH (mobile simulator), which most fully reproduces the working conditions of rescuers in an environment unsuitable for breathing, were carried out, with their further statistical analysis. Statistical analysis of the obtained results was carried out with a significance level of a=0.05. It was determined that for gas and smoke protection workers of all age groups, the very process of inclusion in ASP and the expectation of working in extreme conditions is a significant stress factor for personnel of all age groups. Relevant practical recommendations are offered, in particular: during practical training in compressed air apparatuses by gas and smoke protection officers, special attention should be paid to firefighters and rescuers of the older age group, whose heart rate (HR) begins to exceed 150 beats/min, for the younger age group such control is required by personnel whose heart rate begins to exceed 165 bpm; in the process of operational control and planning of the activities of gas and smoke protection officers at the security post, it is advisable to take into account that the time required to perform an operational task in an environment unsuitable for breathing may be 15-20% longer for personnel of the older age group; at the post of safety during the preliminary calculations of the working time in the ASP for gas and smoke protection devices of all age groups, it is advisable to use the pulmonary ventilation indicator w_л»80 l/min; at the security post, it is advisable to use simplified calculations of working time in ASP. So, for cases of work in an emergency response system with a cylinder volume of 8 l, in general, you can use the indicator of the rate of pressure drop, also at the security post, it is advisable to plan the activities of the units of the GDSS in such a way that they change, if there is a need for long-term emergency and rescue operations, due to 15–20 min.
