2 Step 1: Collection of necessary information
2.1 Sighting of available documents
A practical first step is to collect detailed documents for the ship. The shipowner should try to collate documents normally retained onboard the ship or by the shipping company as well as relevant documents that the shipyard, manufacturers, or classification society may have. The following documents should be used when available:
| Ship's specification | |
| General Arrangement | |
| Machinery Arrangement | |
| Spare Parts and Tools List | |
| Piping Arrangement | |
| Accommodation Plan | |
| Fire Control Plan | |
| Fire Protection Plan | |
| Insulation Plan (Hull and Machinery) | |
| International Anti-Fouling System Certificate | |
| Related manuals and drawings | |
| Information from other inventories and/or sister or similar ships, machinery, equipment, materials and coatings | |
| Results of previous visual/sampling checks and other analysis |
If the ship has undergone conversions or major repair work, it is necessary to identify as far as possible the modifications from the initial design and specification of the ship.
2.2 Indicative list
It is impossible to check all equipment, systems, and/or areas on board the ship to determine the presence or absence of Hazardous Materials. The total number of parts on board may exceed several thousand. In order to take a practical approach, an "Indicative list" should be prepared that identifies the equipment, system, and/or area on board that is presumed to contain Hazardous Materials. Field interviews with the shipyard and suppliers may be necessary to prepare such lists. A typical example of an "Indicative list" is shown below:
2.2.1 Materials to be checked and documented
Hazardous Materials, as identified in appendix 1 of these Guidelines, should be listed in Part I of the Inventory for existing ships. Appendix 1 of the Guidelines contains all the materials concerned. Table A shows those which are required to be listed and Table B shows those which should be listed as far as practical.
2.2.2 Materials listed in Table A
Table A lists the following four materials:
| Asbestos | |

2.2.2.2 Polychlorinated biphenyl (PCBs)
Worldwide restriction of PCBs began on 17 May 2004 as a result of the implementation of the Stockholm Convention, which aims to eliminate or restrict the production and use of persistent organic pollutants. In Japan, domestic control began in 1973, with the prohibition of all activities relating to the production, use and import of PCBs. Japanese suppliers can provide accurate information concerning their products. The "Indicative list" of PCBs has been developed as shown below:
| Equipment | Component of equipment |
| Transformer | Insulating oil |

| Felt under septum plates on top of hull bottom |
2.2.2.3 Ozone depleting substances
The "Indicative list" for Ozone depleting substances is shown below. Ozone depleting substances have been controlled according to the Montreal Protocol and MARPOL Convention. Although almost all substances have been banned since 1996, HCFC can still be used until 2020.

2.2.2.4 Organotin compounds
Organotin compounds include Tributyl tins (TBT), Triphenyl tins (TPT) and Tributyl tin oxide (TBTO). Organotin compounds have been used as anti-fouling paint on ships' bottoms and the International Convention on the Control of Harmful Anti-Fouling Systems on Ships (AFS Convention) stipulates that all ships shall not apply or re-apply organotin compounds after 1 January 2003, and that, after 1 January 2008, all ships shall either not bear such compounds on their hulls or shall bear a coating that forms a barrier preventing such compounds from leaching into the sea. The above-mentioned dates may have been extended by permission of the Administration bearing in mind that the AFS Convention entered into force on 17 September 2008.
2.2.3 Materials listed in Table B
For existing ships it is not obligatory for materials listed in Table B to be listed in Part I of the Inventory. However, if they can be identified in a practical way, they should be listed in the Inventory, because the information will be used to support ship recycling processes. The Indicative list of materials listed in Table B is shown below:
| Materials | Component of equipment |
| Cadmium and cadmium compounds | Nickel-cadmium battery, plating film, bearing |
| Hexavalent chromium compounds | Plating film |
