Along with the development of cities, increase in production facilities and production technologies today, compliance with fire safety requirements is becoming increasingly important. Effective fire safety measures help prevent tragedies and save people’s lives by quickly detecting and responding to fires, reducing material damage by protecting buildings, equipment and other values from fire damage. They help avoid major financial losses that can result from the fire and keep businesses running smoothly. Automatic fire- extinguishing systems operate continuously and without human intervention, meaning they can respond quickly to a fire at any time, even if there are no people in the room. These systems automatically detect the origin of the fire and begin to extinguish it at an early stage, thereby significantly reducing the damage caused by the fire and protecting human lives. The automatic water fire-extinguishing system is an effective fire safety means that significantly reduces the threat of fire spreading and ensures the safety of the building and its users if its operational capacity is regularly maintained and tested. A study was conducted in which the authors of the article examined and compared the experiences of other countries in the operation of sprinkler sprayers for automatic water fire extinguishing systems and conducted an experiment in how the run-off time for the spray flask of the automatic water fire sprinkler system varies, depending on the year of production. As part of this study, the authors investigated also how the timing of the spray flask of the automatic water fire sprinkler system varies depending on the year of production. The effectiveness of the automatic water fire sprinkler system was tested, and recommendations were made to improve its operational capability effectively. © 2025 Latvia University of Life Sciences and Technologies.
