Evaluating Adjustable Pattern Nozzles for Engine Room Fires Aboard Coast Guard Cutters
Abstract
The purpose of this project was to: (1) determine whether the Coast Guard should adopt the Akron 3019 nozzle with a matched in-line foam eductor or use it with the existing LP-6 Coast Guard foam eductor for extinguishing Class B engine room fires, (2) identify alternatives to the Akron 3019 nozzle in cases where it is not the best nozzle for a particular class of cutter, (3) document the pressure/flow characteristics of the fire main on specific classes of Coast Guard cutters, and (4) determine the pressure/flow characteristics of the P250 pump. It is recommended each class of Coast Guard cutter tested should be provided with the Akron 3019 nozzle and a matched in-line eductor (e.g., Akron 2901) for the purpose of extinguishing engine room fires. The Akron 3019 nozzle is also recommended for use on deck fires because of its overall capabilities and its performance under the pressure/flow conditions existing within the different fire mains. The pressure/flow characteristics of the fire main were documented for specific classes of Coast Guard cutters. Pressure/flow characteristics of the P250 pump were determined.
