The Chesapeake Bay Fire Test Facility is concerned with all aspects of shipboard fire safety, particularly as related to flight decks, submarines and interior ship conflagrations. The emphasis is on providing facilities for intermediate scale, credible evaluations of firefighting agents, systems and training concepts under more realistic, shipboard conditions. In many cases, the facility provides a vital link between laboratory testing and full scale, proof of concept on the
Current Research Areas
Evaluation of water mist as a replacement for Halon 1301 for suppressing fires in shipboard machinery spaces, flammable liquid storerooms, and berthing areas.
Qualification of candidate AFFF concentrates.
Aircraft hanger bay suppression systems.
Evaluation of flammability properties of mists, including difficult-to-ignite liquids.
Evaluation of High Expansion Foam for obstructed compartments.
Study of the combustion of gaseous, liquid, and solid fuels and their suppression by water mist and hybrid water mist systems.
Evaluation of gaseous Halon replacements for shipboard applications such as HFC-227 ea.
Two fully instrumented real-scale fire research chambers for testing small (28m
) and large (300m
) compartment fires. Instrumentation includes complete computer automation, continuous gas analyzers, FTIR, oxygen monitors, visible and IR cameras, and laser based droplet size and velocity visualization system.
Computerized gas chromatographs.
Dedicated high-speed data collection and manipulation computers.
Pressurizable 0.3 and 5 m
3 chambers with continuous gas analyzers. A 324 m
3 pressurizable chamber to simulate submarine compartment and enclosure fires. Instrumentation associated with the chamber includes temperature and radiation sensors, continuous gas analyzers, closed circuit television, and computerized data collection and data visualization displays. An engineering layout for large-scale quantitative study of flow proportioning equipment.
Special ovens for testing aging properties of firefighting agents.
A 50' x 50' fire test chamber with variable flow overhead hood and side wall louvers to control the effects of ventilation.
A 10,000 ft
2 mini-deck which affords capabilities for studying characteristics and suppression of aircraft carrier flight deck fires with 30 knot wind capability for study of flight deck fires and suppression techniques. This includes the capability of generating winds of up to 30 knots and of dispensing AFFF from nozzles imbedded in the deck, as on actual aircraft carriers. Facilities for conducting all of the fire and related qualifications tests (except toxicity) under the Military Specification for Aqueous Film Forming Foam (MIL-F-24385).
Two self-propelled mobile instrument vans for remote field tests.
Small-scale plexi-glass chamber for water mist suppression studies of gaseous and liquid fuels.
Forced convection boundary layer apparatus to study combustion of solid fuels and their suppression by water mist and Spectraline® IR diagnostic for flames.
