Description

FUNCTION: Performs large‑scale fire protection experiments that simulate actual Navy platform conditions. Remote control firefighting systems are also tested.

DESCRIPTION: The facility consists of five buildings and three testbeds. Two of the buildings are for enclosed fire experiments, qualification of firefighting agents, efficacy of dispensing these agents, and control and visibility through smoke. A third building is a staging area and a fourth is for storage. The fifth building contains a hydraulics laboratory and is equipped with a full-scale shipboard balanced pressure proportioner for aqueous film-forming foam (AFFF). A testbed simulates the lower section of a submarine for studying bilge fires and their extinguishment. A simulated 930 sq m(10,000 sq ft) flighttestbed is used to develop fire scenarios and suppression technologies. The third testbed has two test compartments, with internal volumes of 28 cu m and 300 cu m(1,000 cu ft and 10,500 cu ft), that are used for fire suppressionexperiments.

INSTRUMENTATION: Specific instruments for these testbeds are incorporated as a function of the particular experiment, but include sensors, gas sampling, control equipment, mixing vessels, calibrated fuel and aqueous flow metering, and video recording. The fire test building (15 m x 15 m; 50 ft x 50 ft) has a large cone calorimeter for full-scale fire tests of materials and furnishings.
