Abstract:
The National Aeronautics and Space Administration,
together with the National Institute of Standards and
Technology are in the third year of a five year project
designed to set guidelines for fire protection in high
bay facilities. There is a special need to address fire
protection issues for high ceiling height (high bay)
spaces. NASA has numerous high bay spaces that are used
to perform a variety of functions, many of which are
critical to meeting the goals of the NASA strategic
plan. Examples of high bay spaces at NASA include those
used for clean rooms, shuttle simulators,
assembly/storage, vacuum and vibration chambers, vehicle
assembly, and/or testing facilities with payloads. These
spaces represent some of the most difficult fire
protection challenges in that detection of a fire in a
large space may be delayed due to the distance smoke and
products of combustion must travel to reach the
detector, the large amount of ambient air for smoke
dilution, the high dollar value of these spaces, and the
low damage threshold of a clean room. Some of these
spaces also involve forced air flow.
