In case of fire, the seals were supposed to prevent flames, smoke and toxic fumes from passing to the off fire side of the wall or floor. With the passage of time, some of the seals shrank, deteriorated and even, in some cases, became combustible, i.e., “non-performing”. One concern, when removing an old seal, is the accidental cutting of cables in the process of removing the old seal material.</div> <bR> <div> In general construction in power plant, etc., often the <B>openings are too small in floors and walls around penetrates</B>, so that the annular spaces are <B>not large enough for a proper firestop</B>. For the nuclear power plants or for buildings with too small annular spaces, we have developed a <B>new method of external fireproofing</B>, see below. </div> <bR> <div> <B>New Methods of External Fireproofing</B></div> <bR> <div> <B>The new method (patent pending)</B> utilizes cementitious Flammadur® E473 material, manufactured by AIK Flammadur Brandschutz GmbH in Germany. The E473 is used <U>on the outside </U>of walls and floors, around the existing penetrants (pipes, conduits, cable trays, busways, cables). It can have a cylindrical form around pipes, conduits and a rectangular form around cable trays and busways, or it can cover the entire wall or floor with multiple penetrates. This external mass extends about 6 inches (152mm) from the surface of a wall or floor, on both sides of a wall or floor, and about 4 inches (102mm) from an outside surface of penetrants.</div> <bR> <div> The semi-liquid E473 is poured between pipes, between conduits and the outside steel sleeve, or between the sides of the cable tray and steel or wooden or other removable damming frame. The E473 is also poured between the cables and between cables and the sides of the cable tray. The semi-liquid E473 expands slightly on curing, making a tight fit, so in case of a fire, <B>this external seal will not permit passage of flames, smoke or toxic fumes through the penetration. </B></div> <bR> <div> Copyright © 2008  Fire Protection Technologies, Inc.  All rights reserved</div> </td> </tr></table></body>
