Everyone who has been involved inane • testing of high piled combustible stockstorage fires over the years understands the importance of pre-, wetting in controlling high piled stock fires. As a fire advances down a,storage rack, the hot gases at ' ceiling level spread in advance of the fire. These hot gases•eventually, spread far enough to activate • sprinklers located over sections of the rack that are not yet involved in .fare. The discharge from these ' • . spiinklera pre -wets the commodity effectively, preventing ignition once the fire doe$ teach that part of the • rack.

' to the attention of the•Artiele 81 Rewrite Committee by the'Natibnal Institute of Standards and Technology (NISI) Building and Fire Research•Laboratory•(BFRL) Test Prograrn called LAVENTS (Link Activated • Vents and'Sprinklers). • This testing demonstrated that if the ceiling smoke layer abdve the fire is allowed to • ' • ' • get to a certain depth or thickness, it can actually result in the smoke and heat being drawn downward by a venturi type action' created as discharge from the operating sprinklers passes through the hot gas layer. - • • ,.. • b ' • ' den N9IS3Q 3dI3 km' WdtiS :P0 86, PI 9flti' - ' . :.: FireProtection Plan , ' : .. . • .. � • 1:., V \ 4C � • P' i-Aty i c 7 -7).:',.. . . • Eagle Hardware & Garden — OR a .o ' -r; B r - '• u_� • ' Page '5 of 11.
