This laboratory was constructed for the testing of materials to be incorporated into ship construction.  Due to the nature of this type of construction, the laboratory air control system was of major importance.  This system included control of the supply and exhaust air systems, relative room/corridor pressure relationship, fumehood and canopy hood variable air volume systems.  This control system operated over 120 rooms, approximately 40 different control sequences of operations and 45 fume and canopy hoods.  HEPA filtering and packaged air-cleaning systems were employed throughout the laboratory facilities.

Also installed to meet the laboratory requirements, was a large acid neutralizing waste system with a 2,020 gallon neutralizing tank, a 20 gpm deionized water system, and two compressed air systems, one for laboratory use, the other for equipment.  There is also a tank storage system with piping and pumping systems for sea water, oily waste water, gray and black sewage, vacuum toilets, jet fuel and TRB testing fluid.
