The findings could have important ramifications for NFPA 13 and for the stakeholders who rely on it. The project also resulted in an analytical tool that can simplify the decision-making process for the placement of ESFR sprinklers in relation to various obstruction configurations and sizes. The research evaluated the potential impact of obstructions on the performance of ESFR sprinklers during fires. The 160-page “ Obstructions and Early Suppression Fast Response Sprinklers,” published in August, summarizes six years of research conducted by Wiss, Janney, Elstner Associates, Inc., the global engineering/architectural firm that partnered with the FPRF on this project. Those restrictions have generated concerns among stakeholders over the years, many of them focused on a central question: Exactly how much do nearby obstructions impact the performance of ESFR sprinkler systems?Ī new report by the Fire Protection Research Foundation (FPRF) offers answers. The current edition of NFPA 13, Standard for the Installation of Sprinkler Systems, includes a number of restrictions that apply to ESFR installations, including the proximity of the sprinklers to nearby obstructions that can include structural elements, duct work, and lighting. ESFR systems utilize fast-acting, high-volume sprinklers designed to protect the most challenging stored goods, including items containing large amounts of highly combustible plastics. The joke illustrates the importance of ESFR systems in protecting an array of high-challenge storage settings, as well as the numerous considerations involved with installing these systems in a storage facility-especially when the installation encounters potential sprinkler obstructions. Serving Waco Temple and Central Texas' best industrial, warehouse and office buildings.There’s a joke in the sprinkler and storage industries that you don’t design an early suppression fast response (ESFR) sprinkler system around a building-you design the building around the ESFR sprinkler system. Pre-action systems - are specialized for use in locations where accidental activation is undesired, such as, Computer Data Facilities for protection of computer equipment from accidental water discharge.Upon activation, water flows from all sprinklers simultaneously

Deluge systems - Water is not present in the piping until the system operates.Water is not present in the piping until the system operates. Dry pipe systems - are most often used when the ambient temperature may be cold enough to freeze.Wet systems - Water is available at each fire sprinkler head and will operate when the heat sensitive element (glass bulb or fusible link) releases, allowing water to flow from that sprinkler.
