Penetrations for cables, cable trays, conduits…that pass through a wall, floor, or floor ceiling assembly constructed as a smoke barrier, or through the ceiling membrane of the roof/ceiling of a smoke barrier assembly, shall be protected by a system or material capable of restricting the passage of smoke.
Especially in pressurized plenums, it is difficult to avoid dust and smoke passig through
Gaseous suppression systems rely on the integrity of the enclosure to retain the extinguishing agent in the event of a fire. In such environments, sealing is essential. Enclosure integrity testing dictated by NFPA 2001 and EN 15004 helps the designer ensure that the proper amount of agent is dispensed and that it will not be lost prematurely thereby allowing re-ignition of a fire
When it comes to engineering gaseous suppression systems, traditional sealing methods for cable penetrations such as caulk or putty or devices integrating foam plugs or requiring an action to open or close the device, introduce variables that can make designing effective enclosures a difficult task.
Since EZ-Path® is essentially self-sealing, we have often been asked about how it might perform in this environment. We posed this question to one of the foremost authorities on enclosure integrity testing in North America, Tim Lochner, a professional engineer who designed, developed, and provided instruction on the equipment used to run the pressure tests dictated by the relevant standards.
Follow the link below to find out why Tim feels that EZ-Path’s predictable performance makes it worth considering for these applications.
