One of its parts is the NFPA 13 standard related to sprinkler fire extinguishing systems, which we will examine in this article from <a href=\"https:\/\/gpavan.com\/En\/category\/articles\/\" target=\"_blank\" rel=\"noopener\">Ganjineh Pavan&#8217;s blog<\/a>.<\/p><h2 style=\"text-align: left;\">What is NFPA?<\/h2><p style=\"text-align: left;\">The National Fire Protection Association (NFPA) is a non-profit organization in America, which was founded in 1896 with the mission of reducing death, injury, and financial and economic damage caused by fire, electricity, and related hazards.<\/p><p style=\"text-align: left;\">NFPA contains more than 300 codes and standards. These standards are designed to minimize the risk and effects of fire by establishing standards for construction, processing, design, service, and installation worldwide.<\/p><p style=\"text-align: left;\">More than 250 technical committees, comprised of approximately 9,000 volunteers, review public input and vote on necessary revisions and revisions in a process endorsed by the American National Standards Institute.<\/p><p>\u00a0<\/p><h2 style=\"text-align: left;\">NFPA 13 standard in Iran<\/h2><p style=\"text-align: left;\">The Third Topic of <a href=\"https:\/\/inbr.ir\/\">Iran&#8217;s National Building Regulations<\/a>, which is dedicated to the protection of buildings against fire, in paragraphs 3-9-4 entitled &#8220;automatic sprinklers and other automatic fire extinguishing systems&#8221; requires compliance with the NFPA 13 standard.<\/p><p style=\"text-align: left;\">Accordingly, until the preparation of the national regulations, the design and installation of automatic sprinkler fire fighting systems should be based on NFPA 13 reference. Therefore, familiarity with this standard is essential for construction and firefighting industry activists.<\/p><h2 style=\"text-align: left;\">General definitions and requirements<\/h2><p style=\"text-align: left;\">Because fire <a href=\"https:\/\/qpket.com\/product-category\/fire-fighting\/water-fire-fighting-system\/sprinkler\">sprinkler<\/a> design involves many technical concepts, NFPA 13 devotes Chapter 3 to defining key terms used throughout the document.<\/p><p style=\"text-align: left;\">A sprinkler or automatic sprinkler system is defined as a fire suppression or control device that operates automatically when its heat-activated element is heated to its rated temperature or higher, allowing water to discharge in a specified area.<\/p><figure id=\"attachment_20288\" aria-describedby=\"caption-attachment-20288\" style=\"width: 1600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-20288 size-full\" src=\"https:\/\/gpavan.com\/wp-content\/uploads\/2022\/08\/Fire-Sprinkler-Systems.jpg\" alt=\"Occupancy classification is listed in NFPA 13.\" width=\"1600\" height=\"1000\" \/><figcaption id=\"caption-attachment-20288\" class=\"wp-caption-text\">Occupancy classification is listed in NFPA 13.<\/figcaption><\/figure><p style=\"text-align: left;\">The general requirements apply to all sprinkler fire extinguishing systems regardless of building type or specific configuration, unless specifically exempted in the code.<\/p><p style=\"text-align: left;\">If a building uses fire sprinklers, NFPA 13 requires complete coverage of the entire property, unless the standard indicates that a specific building area is optional.<\/p><h3 style=\"text-align: left;\">The table of classification of building possession based on the level of risk<\/h3><table class=\" alignleft\"><tbody><tr><td width=\"312\"><p style=\"text-align: center;\"><strong>Description<\/strong><\/p><\/td><td width=\"312\"><p style=\"text-align: center;\"><strong>Classification of building occupancy based on the level of risk<\/strong><\/p><\/td><\/tr><tr><td width=\"312\">Low combustible content and low heat emission are expected from fire.<\/td><td width=\"312\">Light Hazard.<\/td><\/tr><tr><td width=\"312\"><p>Group 1:<\/p><p>Low flammability, a moderate amount of combustible material, height of stacks no higher than 2.44 m, and moderate heat release from the fire is expected.<\/p><p>Group 2:<\/p><p>Combustibility and the amount of content varies from medium to high.

As such, There are four classes or classes, I through IV, with Class I being the least vulnerable to fire and Class IV being the most vulnerable. Classification is determined based on the material stored and used containers (boxes, pallets, crates, containers, etc.).<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-22269\" src=\"https:\/\/gpavan.com\/En\/wp-content\/uploads\/2022\/08\/IMG_0552-scaled.jpg\" alt=\"Classification of stored materials\" width=\"2560\" height=\"1707\" srcset=\"https:\/\/gpavan.com\/En\/wp-content\/uploads\/2022\/08\/IMG_0552-scaled.jpg 2560w, https:\/\/gpavan.com\/En\/wp-content\/uploads\/2022\/08\/IMG_0552-300x200.jpg 300w, https:\/\/gpavan.com\/En\/wp-content\/uploads\/2022\/08\/IMG_0552-1024x683.jpg 1024w, https:\/\/gpavan.com\/En\/wp-content\/uploads\/2022\/08\/IMG_0552-768x512.jpg 768w, https:\/\/gpavan.com\/En\/wp-content\/uploads\/2022\/08\/IMG_0552-1536x1024.jpg 1536w, https:\/\/gpavan.com\/En\/wp-content\/uploads\/2022\/08\/IMG_0552-2048x1365.jpg 2048w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" \/><\/p><p style=\"text-align: left;\">Fire sprinkler system components and installation in NFPA 13 Standard<\/p><p style=\"text-align: left;\">The main content of NFPA 13 is a description of all components used in automatic sprinkler fire extinguishing systems and a description of their correct installation method and mechanical support requirements.
