Improving internal fire water supply systems in student dormitories

Summary

The need of conducting an expertise of the internal fire water supply systems in old buildings of student dormitories in accordance with the requirements of paragraphs 55 and 57 of the «Rules of the fire safety arrangements in the Russian Federation» is substantiated. Cases of inefficient use of the internal water supply system in such buildings in the event of a fire are considered. Based on the study of the internal fire water supply system of a dormitory building in order to improve similar systems, the following is proposed: to carry out a test calculation of the operating systems no less than the service life specified in the passport of the manufacturer of the boosting pump; for quick suppression of a possible fire (before the formation of critical parameters of fire hazards) the boosting pumps should be activated not by the remote start buttons but by the automatic fire alarm system with its start duplicating by the start button in the clock at the security desk of the dormitory; for the effective use of internal fire water supply systems with the simultaneous evacuation of students the boxes of fire hydrants should be equipped with filter self-rescuers (at least three).
