Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

APPENDIX B 311 A2.4 A fixed fire detection and fire-extinguishing system should be installed in enclosed spaces containing incinerators, in combined incinerator/ waste storage spaces and in any waste storage space in accordance with the following table: Automatic Fixed fire- Fixed fire sprinkler system extinguishing detection system system Combined X incinerator and waste storage space Incinerator space X X Waste storage X space A2.5 Where an incinerator or waste storage space is located on weather decks it must be accessible with two means of fire extinguishment: either fire hoses, semi-portable fire extinguishers, fire monitors or a combination of any two of these extinguishing devices. A fixed fire-extinguishing system is acceptable as one means of extinguishment. A2.6 Flue uptake piping/ducting should be led independently to an appropriate terminus via a continuous funnel or trunk. A3 - Incinerators integrated with heat recovery units A3.1 The flue gas system, for incinerators where the flue gas is led through a heat recovery device, should be designed so that the incinerator can continue operation with the economizer coils dry. This may be accomplished with bypass dampers if needed. A3.2 The incinerator unit should be equipped with a visual and an audible alarm in case of loss of feed-water. A3.3 The gas side of the heat recovery device should have equipment for proper cleaning. Sufficient access should be provided for adequate inspection of external heating surfaces. A4 - Flue gas temperature A4.1 When deciding upon the type of incinerator, consideration should be given as to what the flue gas temperature will be. The flue gas temperature can be a determining factor in the selection of materials for fabricating the stack. Special high-temperature material may be required for use in fabricating the stack when the flue gas temperatures exceed 430°C.

Marine debris is a serious environmental problem. To do its part, the United States has agreed to abide by the international treaty for garbage control at sea, known as MARPOL 73/78 Annex V.

Clean Ships, Clean Ports, Clean Oceans explores the challenge of translating Annex V into workable laws and regulations for all kinds of ships and boats, from cruise ships to fishing crafts and recreational boats. The volume examines how existing resources can be leveraged into a comprehensive strategy for compliance, including integrated waste management systems and effective enforcement.

Clean Ships, Clean Ports, Clean Oceans describes both progress toward and obstacles to Annex V compliance. The book covers:

  • How shipborne garbage orignates and what happens to garbage discharged into the seas.
  • Effects of discharge on human health, wildlife safety, and aesthetics.
  • Differences in perspective among military, industrial, and recreational seafarers and shoreside facilities.

Clean Ships, Clean Ports, Clean Oceans will be important to marine policymakers, port administrators, ship operations officers, maritime engineers, and marine ecologists.
