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.
