The guidelines on this subject provide recommendations for developing the Inventory of Hazardous Materials to assist compliance with regulation 5 (Inventory of Hazardous Materials) of the Hong Kong International Convention. The objective of the Inventory is to provide ship-specific information on the actual hazardous materials present on board, in order to protect health and safety and to prevent environmental pollution at ship recycling facilities. This information will be used by the ship recycling facilities in order to decide on, how to manage the types and amounts of materials identified in the Inventory of Hazardous Materials (regulation 9 of the Convention).
A reader may get confused between the tables and appendices. In understanding the overall distribution of information in the Convention and the guidelines, a brief extract of information is as follows:
Appendix 1 of these guidelines provides information on the hazardous materials that may be found on board a ship. Materials set out in appendix 1 should be listed in the Inventory. Each item in appendix 1 of these guidelines is classified under tables A, B, C or D, according to its properties:
Table A comprises the materials listed in appendix 1 of the Convention, (Asbestos, Ozone-depleting substances, Polychlorinated biphenyls (PCB), Anti-fouling compounds and systems);
Table B comprises the materials listed in appendix 2 of the Convention(Cadmium, Chromium Compounds, Lead & Mercury Compounds, Biphenyl & Diphenyl Ethers, Naphthalenes, Radioactives, certain Paraffins );
Table C (potentially hazardous items) comprises items which are potentially hazardous to the environment and human health at ship recycling facilities; and
Table D (Regular consumable goods potentially containing hazardous materials) comprises goods which are not integral to a ship and are unlikely to be dismantled or treated at a ship recycling facility.
The Inventory should be developed on the basis of the standard format set out in appendix 2 of these guidelines. Part I (Materials in structure or equipment) of the Inventory for new ships should be developed at the design and construction stage. Guidance regarding preparation of a diagram showing the location of the materials listed in table A is recommended in order to help ship recycling facilities gain a visual understanding of the Inventory.
The guidance is provided on development of part II (generated wastes) of the inventory. Once the decision to recycle a ship has been taken, part II of the Inventory should be developed before the final survey, taking into account that a ship destined to be recycled shall conduct operations in the period prior to entering the Ship Recycling Facility in a manner that minimizes the amount of cargo residues, fuel oil and wastes remaining on board (regulation 8.2 of the Convention).
Guideline, next guides on development of part III of the Inventory (stores). Once the decision to recycle has been taken, part III of the Inventory should be developed before the final survey, taking into account the fact that a ship destined to be recycled shall minimize the wastes remaining on board (regulation 8.2 of the Convention). Each item listed in part III should correspond to the ship’s operations during its last voyage.
LIST OF APPENDICES
Appendix 1: Items to be listed in the Inventory of Hazardous Materials
Appendix 2: Standard format of the Inventory of Hazardous Materials
Appendix 3: Example of the development process for part I of the Inventory for new ships
Appendix 4: Flow diagram for developing part I of the Inventory for existing ships
Appendix 5: Example of the development process for part I of the Inventory for existing ships
Appendix 6: Form of Material Declaration
Appendix 7: Form of Supplier’s Declaration of Conformity
Appendix 8: Examples of table A and table B materials of appendix 1 with CAS-numbers
Appendix 9: Specific test methods
Appendix 10: Examples of radioactive sources
The layout of inventories s illustrated in Appendix 1 is as follows:
Appendix 2 provides standard format of the inventory of hazardous materials under part I (hazardous materials contained in the ship’s structure and equipment). This category is further subdivided into I-1 (Paints and coating systems), I-2(Equipment and machinery) & I-3 (Structure and hull) containing materials listed in table A and table B of appendix 1 of these guidelines.
Important subdivisions of Part III (Stores) are:
III-2: Liquids sealed in ship’s machinery and equipment.
III-3: Gases sealed in ship’s machinery and equipment.
III-4: Regular consumable goods potentially containing hazardous materials.
Appendix 3 provides example of the development process for part I of the inventory for new ships. Table 3 illustrates examples of location names. Appendix 4 is flow diagram for developing part I of the inventory for existing ships. Appendix 5 gives example of the development process for part I of the inventory for existing ships. Compilation of part I of the Inventory of Hazardous Material for existing ships involves the following five steps.
Step 1: Collection of necessary information;
Step 2: Assessment of collected information;
Step 3: Preparation of visual/sampling check plan;
Step 4: Onboard visual/sampling check; and
Step 5: Preparation of part I of the Inventory and related documentation.
