Abstract : The Phase II tests were conducted in a simulated machinery space on the Navy's fire test ship, the ex-USS Shadwell. It was the same space as used in the Phase I tests except that it was fitted with mockups of equipment to farther evaluate the firefighting capabilities of the water mist system in a more realistic machinery space environment. The fire threats were a combination of spray and pan fires in the range of 2.5 to 7.5 MW. Five different types of spray nozzles were evaluated. Initially, the nozzles were installed in the overhead at one level as in the Phase I study. Then, to improve the performance of the system, the nozzles were installed on two levels as is the practice with Halon systems. With the best system, all of the fires were extinguished in less than 25 seconds, using less than lOO% (25 gallons) of water
