Introduction
The fire fighting training program for U.S. Navy personnel includes field exercises
involving the extinguishing of oil fires burned on the surface of water pools. A 6% solution of the chemical compound known as "Aqueous Film Forming Foam" (AFFF),
frequently referred to as "light water," is used alone or in a combination with Purple K
Powder (PKP), potassium bicarbonate, to extinguish the fire. The Fleet Training Center
Fire Fighting School in Norfolk, Virginia, conducts various shipboard fire training exercises for U.S. Navy Atlantic Fleet personnel. In addition to open tank fires, other simulated
shipboard type structures are utilized for fire training. The existing Fire Fighting School
Facilities (FFS) are located adjacent to the Hampton Roads Sanitation District's (HRSD)
Army Base Wastewater Treatment Plant, a publicly owned treatment works (POTW).
Construction of a $2.8 million fire fighting school has been completed on a site adjacent to the existing school (Figure 1). New shipboard and similar open pool training
structures have been provided along with environmental controls to reduce air and water
emissions. An existing structure, No. 9 Aircraft Flight Deck, has been retained and interfaced with the new facilities (Figures 2 and 3).
