id=\"cosa-prevede-la-uni-en-12845-sul-criterio-di-uso-esclusivo\" class=\"wp-block-heading\">What Does UNI EN 12845 Specify Regarding the Criterion of Exclusive Use?<\/h2>\n\n<p class=\"wp-block-paragraph\">The general criterion for <em>exclusive local fire protection use<\/em> is based on the provisions of <strong>UNI EN 12845 \u2013 10.3.1<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">The requirement is clear: <strong>pump-sets<\/strong> must be installed in rooms with <strong>a fire resistance rating of at least 60 minutes<\/strong>, and such rooms must be <strong>used exclusively for fire protection purposes<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">This section serves as the starting point for understanding when a fire-protection room must be \u201cdedicated\u201d and free of any other systems or uses.<\/p>\n\n<h2 id=\"a-quali-locali-si-applica-in-modo-tassativo\" class=\"wp-block-heading\">To which establishments does this apply strictly?<\/h2>\n\n<p class=\"wp-block-paragraph\">In the text, this requirement is specified as <strong>mandatory<\/strong> for all establishments that host:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>pressurization systems for sprinkler systems<\/strong>;<\/li>\n\n\n\n<li><strong>pressurization systems for use with sprinkler systems and fire hydrant systems<\/strong> (so-called <strong>combined supply<\/strong> systems).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">In these cases, <em>the exclusive use of a fire-safe room<\/em> is not a matter of \u201cinterpretation\u201d: it is an organizational and facility-related rule that defines <strong>how<\/strong> the room may be used.<\/p>\n\n<h2 id=\"cosa-puo-e-non-puo-stare-dentro-un-locale-a-uso-esclusivo\" class=\"wp-block-heading\">What Can (and Cannot) Be Inside a \u201cFor Exclusive Use\u201d Premises<\/h2>\n\n<p class=\"wp-block-paragraph\">If a room contains a unit that supplies a <strong>sprinkler<\/strong> system or that supplies <strong>both<\/strong> a <strong>sprinkler<\/strong> system and a <strong>fire hydrant<\/strong> system, the text clarifies the practical effect of the criterion.<\/p>\n\n<p class=\"wp-block-paragraph\">The following are the <strong>only<\/strong> items allowed in the venue:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>the <strong>pressurization unit<\/strong>;<\/li>\n\n\n\n<li>its <strong>accessories<\/strong>.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">The following are not permitted:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>other machines<\/strong>;<\/li>\n\n\n\n<li><strong>material storage areas<\/strong>.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Therefore, when designating<em>a space for exclusive fire protection use<\/em>, the goal is to prevent the space from being \u201cmixed\u201d with other uses unrelated to fire protection.<\/p>\n\n<h2 id=\"reti-idranti-naspi-regola-generale-ed-eccezioni-ammesse\" class=\"wp-block-heading\">Fire Hydrant\/Reel Systems: General Rule and Permitted Exceptions<\/h2>\n\n<p class=\"wp-block-paragraph\">For premises that house pressurization units used with <strong>fire hydrant<\/strong> systems <strong>or fire hoses<\/strong>, the text sets forth the same criteria as those mentioned above, but also specifies <strong>exceptions<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">The reference cited is:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>UNI 10779:2021, Appendix A \u2013 Water Supplies, Section A.1.1<\/strong><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Furthermore, it is specified that the minimum requirements of <strong>UNI 11292<\/strong> apply to premises that house fire hydrant supply systems.<\/p>\n\n<p class=\"wp-block-paragraph\">The key point, however, is this: <strong>if it is not possible<\/strong> to locate <strong>fire pumps<\/strong> in dedicated rooms, they may be located (with certain restrictions) in rooms shared with other technical systems, <strong>provided they are limited to electric units<\/strong>.<\/p>\n\n<h2 id=\"quando-luso-esclusivo-torna-tassativo-caso-motori-diesel\" class=\"wp-block-heading\">When exclusive use becomes mandatory (e.g., diesel engines)<\/h2>\n\n<p class=\"wp-block-paragraph\">The text concludes with a very clear operational distinction.<\/p>\n\n<p class=\"wp-block-paragraph\">In a room equipped with a pressurization system that serves a network <strong>of fire hydrants and\/or fire hoses<\/strong>,<em>the room\u2019s sole purpose<\/em> is:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>mandatory only if diesel engines are present<\/strong>;<\/li>\n\n\n\n<li>Otherwise, the <strong>exceptions<\/strong> already described apply (namely, only electrical units are permitted in common areas, provided that the conditions are met).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">This distinction is useful because it prevents a \u201cone-size-fits-all\u201d interpretation of the concept of exclusive use: the rule remains fundamental, but its scope of application varies depending on the group\u2019s configuration and the type of drive.<\/p>\n\n<h2 id=\"requisiti-minimi-quando-si-usano-locali-non-esclusivi-unita-elettriche\" class=\"wp-block-heading\">Minimum Requirements for the Use of Non-Exclusive Premises (Electrical Units)<\/h2>\n\n<p class=\"wp-block-paragraph\">When it is not possible to have dedicated spaces and the provisions regarding eligibility apply ( <strong>electric vehicles<\/strong> only), the text lists specific conditions that must all be met simultaneously.<\/p>\n\n<p class=\"wp-block-paragraph\">The room shared with other technical systems must be:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>characterized by <strong>a very low risk of fire<\/strong>;<\/li>\n\n\n\n<li>with <strong>a fire load of less than 100 MJ\/m\u00b2 in any case<\/strong>;<\/li>\n\n\n\n<li><strong>accessible directly from the outside<\/strong>;<\/li>\n\n\n\n<li><strong>separated<\/strong> from adjacent rooms (if any) by fire-resistant structures <strong>appropriate for the<\/strong> fire resistance <strong>class<\/strong> of the rooms, with a <strong>minimum rating of 60 minutes<\/strong>.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Finally, the room temperature must be compatible with the pumps\u2019 specifications and ensure <strong>that<\/strong> the pumps <strong>are protected from freezing<\/strong>: <strong>t &gt; 4 \u00b0C<\/strong>.<\/p>\n\n<h2 id=\"sintesi-finale-operativa\" class=\"wp-block-heading\">Final Operational Summary<\/h2>\n\n<p class=\"wp-block-paragraph\">To sum it up in practical terms:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>If the room houses <strong>sprinklers<\/strong> (or <strong>sprinklers and fire hydrants<\/strong>): <em>the room must be used exclusively for firefighting purposes<\/em> <strong>at all times<\/strong>, containing only the firefighting equipment and accessories, with <strong>no<\/strong> storage or other machinery.<\/li>\n\n\n\n<li>If the room supplies <strong>fire hydrants\/hose reels<\/strong>: the general rule applies, but with <strong>exceptions<\/strong> when a dedicated room is not possible\u2014 <strong>only for electrical equipment<\/strong> and only if the specified conditions are met.<\/li>\n\n\n\n<li>If <strong>diesel engines<\/strong> are present (hydrants\/hose reels): exclusive use is <strong>mandatory<\/strong>.<\/li>\n<\/ul>\n\n<h2 id=\"conclusione\" class=\"wp-block-heading\">Conclusion<\/h2>\n\n<p class=\"wp-block-paragraph\">The key point is not to confuse a \u201cfire protection room\u201d with \u201cany other utility room\u201d:<em>the exclusive use of a fire protection room<\/em> is a criterion that\u2014particularly for sprinkler systems and combined power supplies\u2014requires a dedicated purpose without any other functions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8220;Exclusive use as a fire protection room&#8221; means that the room is used solely for fire protection purposes.
