Federal Hall National Memorial is, as they say in Hollywood, "having work done." But unlike the glitterati, Federal Hall's work is far more than cosmetic. This icon of New York City's financial district is getting a new fire suppression system to allow Federal Hall to protect sensitive artifacts in both NPS and visiting collections.
The state-of-the-art misting system will be triggered in the same way a traditional sprinkler is, but instead a showering the affected area with large quantities of water, it will spray a fine mist that will fill the space, both damping down any flames while displacing the oxygen that enables a fire to burn.
The installation process is being done in phases. Phase I, which took place last week, involved drilling through the historic structure's thick granite walls and ceilings in preparation for Phases 2 and 3, which will see the installation of riser and branch piping throughout the building. Between the noise and the dust, it was decided that visitor safety would best be served by closing the site to the public for the duration of Phase I.
