4 Identification of Potentially Hazardous Materials

  4.1 The principal materials of a ship (e.g., steel, aluminium) are not an overriding concern from the standpoint of human health or marine pollution. However, there are a number of potential sources of concern that should be addressed such as:

  • .1 fuel, lubricants, and coolants;

  • .2 floatable materials (e.g., plastics, Styrofoam insulation);

  • .3 materials possibly containing PCBs such as wiring insulation;

  • .4 sludges;

  • .5 harmful aquatic organisms in ballast water; and, currently (on older ships)

  • .6 asbestos used as insulation material and in accommodation panelling.

  4.2 Items on ships that may potentially contain substances of concern include:

  • .1 electrical equipment (e.g., transformers, batteries, accumulators);

  • .2 coolers;

  • .3 scrubbers;

  • .4 separators;

  • .5 heat exchangers;

  • .6 storage facilities for production and other chemicals;

  • .7 tanks, diesel tanks including bulk storage tanks;

  • .8 stored solvents, and other chemical stocks;

  • .9 paints;

  • .10 electrical cabling installed before 1975 (plastic covering may contain PCBs);

  • .11 sacrificial anodes;

  • .12 fire extinguishing and fire fighting equipment;

  • .13 piping, valves and fittings;

  • .14 pumps and compressors;

  • .15 engines and generators;

  • .16 oil sumps;

  • .17 hydraulic systems; and

  • .18 light fittings and fixtures.

  4.3 In identifying potentially hazardous materials on board ships, there are two key lists to consider for guidance, which are set out as Appendices 1 and 2 to these Guidelines: Appendix 1 is based on the "List of Hazardous Wastes and Substances under the Basel Convention that are relevant to Ship Dismantling" (Appendix B to the "Technical Guidelines for the Environmentally Sound Management of the Full and Partial Dismantling of Ships"), and Appendix 2 is based on the list of “Potentially hazardous materials which may be on board vessels delivered to recycling yards” (Annex 1 of the “Industry Code of Practice on Ship Recycling”).
