developed. Based on the • inforrnation that was exchanged during our phone conversation, we understand that you .
• . • • are currently using the 1994 Editions of the 'Uniform Codes. "Accordingly; this plan•,is based specifically on the . •

sprinklered buildings: We support the installation of smoke and heat vents and acknowledge their effectiveness. • •

• It is, however, requested that a vari9nee to the curtain board requirements in 'Article 81, of the 1994 'UFC and

••
urtain Boards in' Sprinkiered Buildings. Rdof vents and curtain boards were ooiginallyused as an aid to .
fire lighting in unspnnklergd buildings. In an unsprinlcleredi;uildin ' roof augmented
s, roo by curtain
• , ' : boards,'can sometimes relieve smoke accumulation by containing radial movement along the ceiling to a •
• tingle curtain board zone and then permitting the smoke to escape through•the vents in that zone..In_, • • '
• • spririklered buildings,,vents and curtain boards are of much less value because the operating sprinklers have • '
• a significant impact, on the way.in' which •the hot Smoke layer develops. Recentfire testiig has shown that •
• ' within sprinldered,buildings, curtain boards provided little or,no benefit relative to smoke containmentand•
• • removal ;'they are sometimes detrimental to fire'sprinkler system operation, and in some cases can•actually '• • • ' iacreasburning intensity and•fire•spread _ : • • - ; , •
(2) ;Prevent pre- wetting of commodities by the sprinkler system. 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. It is important that pre - wetting occur before the fire gets to large, or else the radiant heat will • • •

(3) Thickness of the -Upper Snioke Layer. A major concern has developed regarding the thickness of the upper '
• . ' smoke layer at the ceiling level over the fire:' Recenttesting has Shown that smoke logging in the fire• area • .
• can occur when the ceiling. sprinkle= discharge passes through hot smoke layer. •This•issue was brought .
. . ' 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. -
