Garner Palenske, P.E., from Jensen Hughes presented work completed for the Research Foundation on Early Suppression Fast Response (ESFR) sprinklers and obstructions to a packed room at the NFPA Conference in Las Vegas this morning. Attendees heard a summary of the previous work on Phase 1 and Phase 2, including results from full scale testing that was completed.
Garner also described the process that is being used for the current Phase 3 effort with the Research Foundation that includes Actual Delivered Density (ADD) testing and full scale testing. The focus of this phase is on obtaining more specific information about the impact of vertical distance and obstruction width of bridging members. The overall objective of the research program is to develop a tool that can be used for providing reliable analysis of the impact of obstructions on ESFR sprinklers based on existing data and develop technical basis to the Technical Committees for NFPA 13, Standard for the Installation of Sprinkler Systems, for new requirements and guidance. The Phase 3 report will be available by the end of this year.
