Free webinar on "Storage Protection under Sloped Ceilings"

Blog Post created by amandakimball Employee on Aug 6, 2019

In the event of a fire, a sloped ceiling may alter sprinkler performance from expected results for a conventional horizontal ceiling configuration. Prior computational studies investigated the effect of ceiling slope on sprinkler activation times and patterns, and spray dynamics. The role of obstructed ceiling construction and sprinkler orientation were investigated in detail and a test plan for cold-flow and large-scale fire tests was developed. Based on which, cold-flow experiments were conducted using a variety of different sprinklers to examine the impact of ceiling slope and deflector orientation on the measured floor flux. The cold flow test results helped to further refine the test plan for a series of large-scale fire suppression tests conducted with pendent, early suppression, fast response sprinklers under sloped ceilings in presence of obstructed ceiling construction. The large-scale testing and modeling results will provide guidance for updates to sprinkler installation standards. This webinar will discuss the findings from this effort explaining the fire dynamics affecting fire suppression performance under sloped ceilings. The final project report will be available on the FPRF website.
