- W3209508780 abstract "Purpose. The article analyzes the studies devoted to the use of personal respiratory and eye protection equipment by firefighters during fire suppression at power facilities. The authors propose a method that will ensure the continuity of actions to suppress a fire in contaminated environments that are immediately dangerous to life and health (IDLH) with the help of a constant supply of air from a safe area directly to the breathing apparatus. Methods. Based on the analysis of statistical data, the authors determine the frequency of using personal respiratory and eye protection equipment types at power facilities and dependencies of firefighting duration on the distance travelled to the heart of a fire. Findings. It was identified that in most cases, compressed air breathing apparatus (CABA) were used to suppress extra-period fires at power facilities. It was also determined that the total operating time of smoke diving squads in case of fires at power facilities at 260 and 300 atm pressure in compressed air cylinders includes: 1) travelling a distance to the heart of a fire and back; 2) suppressing a fire. The authors propose a method of combined action of a compressor and a self-contained breathing apparatus with compressed air that will increase the time of work of firefighters equipped with CABAs. Such a necessity may be caused by cases when the required time ofwork in IDLH environments exceeds the time of the protective CABA operation. Research application field. The study results make a significant adaptation of methods and the development of technical means necessary to solve problems of continuous fire suppression using personal respiratory and eye protection equipment. Conclusions. The authors propose a method to ensure the work continuity in IDLH environments by supplying air into a breathing apparatus from a safe area. In order to achieve the final result of the presented method, it is necessary to conduct a number of studies that includes: justification of the air compressor type and auxiliary devices; calculation of the required air volume in the manifold; analysis of permissible distances for steady device operation; investigation of the device operation effect on the convenience of movement of firefighters and on their physical condition." @default.
