3 Step 2: Assessment of collected information
Preparation of a checklist is an efficient method for developing the Inventory for existing ships in order to clarify the results of each step. Based on collected information including the "Indicative list" mentioned in Step 1, all equipment, systems, and/or areas onboard assumed to contain Hazardous Materials listed in Tables A and B should be included in the checklist. Each listed equipment, system, and/or area on board should be analysed and assessed for its Hazardous Materials content.
The existence and volume of Hazardous Materials may be judged and calculated from the Spare parts and tools list and the Maker's drawings. The existence of asbestos contained in floors, ceilings and walls may be identified from Fire Protection Plans, while the existence of TBT in coatings can be identified from the International Anti-Fouling System Certificate, Coating scheme and the History of Paint.
Example of weight calculation
| No. | Hazardous Materials | Location/Equipment/ Component | Reference | Calculation |
| 1.1–2 | TBT | Flat bottom/paint | History of coatings | |
| 1.2-1 | Asbestos | Main engine/ Exh. pipe packing | Spare parts and tools list | 250 g x 14 sheet = 3.50 kg |
| 1.2-3 | HCFC | Ref. provision plant | Maker's drawings | 20 kg x 1 cylinder = 20 kg |
| 1.2-4 | Lead | Batteries | Maker's drawings | 6 kg x 16 unit = 96 kg |
| 1.3-1 | Asbestos | Engine-room ceiling | Accommodation plan |
When a component or coating is determined to contain Hazardous Materials, a "Y" should be entered in the column for "Result of document analysis" in the checklist, to denote "Contained". Likewise, when an item is determined not to contain Hazardous Materials, the entry "N" should be made in the column to denote "Not contained". When a determination cannot be made as to the Hazardous Materials content, the column should be completed with the entry "Unknown".
