Evaluation of Requirements for Commercial Nozzles on Merchant Vessels.
Abstract
An investigation was conducted to evaluate the shipboard firefighting requirements for nozzles used on merchant vessels and to determine if commercial nozzles could replace Coast Guard-approved nozzles. The first phase of the evaluation involved interviewing Coast Guard Marine Inspection Officers and personnel from marine firefighting institutions. They were asked to describe shipboard firefighting requirements and to assess present-day U.S. Coast Guard regulations governing the use of approved nozzles. The second phase of the evaluation involved collecting debris samples from the fire main systems of different merchant vessels and to evaluate the nozzle requirements needed for passing this debris. The information supplied by Coast Guard Marine Inspection Officers and marine firefighting institutions indicates that commercial nozzles, at present, do not completely address marine firefighting requirements. The collected data indicates that the debris found in shipboard fire main systems is sufficient to clog up commercial nozzle tip openings and to reduce their overall effectiveness. It is therefore recommended that commercial nozzles which do not comply with Coast Guard regulations not be used on merchant vessels. (Author)
