DESIGN PROBLEMS OF THE IN-BUILDING FIRE PIPELINE ON THE BASE OF LOW-FLOW FIRE HYDRANTS OF LOW AND HIGH PRESSURE. PART 1. ANALYTICAL REVIEW OF LOW-FLOW FIRE HYDRANTS AND THEIR ANALOGUES
There was carried out an analytical review and analysis of domestic, international and European standards and normative documents for the in-building fire pipeline. Comparative hydraulic parameters of low-flow fire hydrants of various manufacturing companies as well as analogues of technical means used for fire extinguishing are presented. It is noted that the successful introduction of low-flow fire hydrants abroad is promoted by the developed system of normative documents in the field of low-flow in-building fire pipeline. There are described advantages and circumstances that contribute to the widespread introduction of low-flow fire hydrants applicable to the in-building fire pipeline of buildings of various functional purposes. There is justified the use of new effective technologies for in-building fire pipeline with low-flow fire hydrants of low and high pressure, including water mist, for the internal opposite water pipe in view of the fact that in the arsenal of fire service there are knapsack and mobile fire extinguishing systems that complete first aid motorcycles and are equipped with low-flow fire hydrants of water mist. It is proposed to limit the use of traditional fire hydrants by residents and staff of a facility. The use of low-flow fire hydrants instead of traditional fire hydrants for fire extinguishing by residents or personnel is proved.
