Proper fire protection is essential in every building \u2013 in the event of danger, it can even determine the safety and survival of occupants. According to Polish law, certain types of buildings must be equipped with indoor hydrants<\/strong>, and their placement and use are defined by binding regulations. Detailed requirements are set out in the Regulation of the Minister of Internal Affairs and Administration of June 7, 2010, on fire protection of buildings, other construction facilities, and areas<\/strong>.<\/p>\n

Let\u2019s take a closer look at the rules.<\/p>\n

Different Types of Hydrants and Their Applications<\/h3>\n

Hydrants mainly differ in diameter<\/strong>, which determines their water output. They also vary in hose design, reels, and cabinet construction. The numbers in their names indicate the internal hose diameter in millimeters.<\/p>\n

    \n
  • \n

    DN25 hydrants<\/strong> \u2013 applied in fire zones categorized as human hazard (ZL). Required in high-rise and tall buildings on every floor (except the floor classified as ZL), and in low- and medium-rise buildings on every floor when:<\/p>\n

      \n
    • \n

      the fire zone exceeds 200 m\u00b2 (ZL I, ZL II, or ZL V),<\/p>\n<\/li>\n

    • \n

      the fire zone exceeds 200 m\u00b2 in a medium-rise ZL III building, or over 1000 m\u00b2 in a low-rise ZL III building.
      DN25 hydrants are commonly used in public utility buildings and collective housing facilities such as schools, hotels, shopping centers, banks, offices, pharmacies, and stores. Their advantage lies in ease of use<\/strong> and efficiency in areas where fires develop relatively slowly but are detected quickly.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

    • \n

      DN33 hydrants<\/strong> \u2013 required in enclosed single-level garages with more than 10 parking spaces and in multi-level garages. Fires in these locations tend to be intense but confined to a specific area. DN33 hydrants are an excellent solution as they deliver a large water flow<\/strong> while remaining easy to operate.<\/p>\n<\/li>\n

    • \n

      DN52 hydrants<\/strong> \u2013 used in:<\/p>\n

        \n
      • \n

        fire zones (PM) with a fire load density above 500 MJ\/m\u00b2 and area exceeding 200 m\u00b2,<\/p>\n<\/li>\n

      • \n

        PM fire zones with rooms larger than 100 m\u00b2 and fire load density over 1000 MJ\/m\u00b2,<\/p>\n<\/li>\n

      • \n

        low- or medium-rise buildings at entrances to PM or technical rooms over 200 m\u00b2 with fire load density exceeding 500 MJ\/m\u00b2 located in ZL I, ZL II, ZL III, or ZL V zones.
        Their use is justified in warehouses and industrial facilities, where fires are not always detected immediately and large quantities of materials intensify the hazard. DN52 hydrants ensure fast and effective fire suppression<\/strong>.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

        Where Should They Be Installed?<\/h3>\n

        During a fire, the presence of hydrants is not enough \u2013 proper placement is critical<\/strong>. According to regulations, hydrants should be installed in particular at:<\/p>\n

          \n
        • \n

          building entrances and stairwells on each floor (in high-rise buildings, DN52 valves are recommended in fire lobbies, permissible on staircases),<\/p>\n<\/li>\n

        • \n

          passages and corridors, including lobbies and corridors of each floor in tall buildings,<\/p>\n<\/li>\n

        • \n

          attic entrances,<\/p>\n<\/li>\n

        • \n

          entrances to open spaces or emergency exits from production and storage rooms, especially in explosion-hazard areas.<\/p>\n<\/li>\n<\/ul>\n

          This placement ensures easy access, optimal coverage, and maximum firefighting efficiency. It allows hoses to reach every room and deliver water to every corner of the building.<\/p>\n
