Overview
ISO 30006:2010 - Ship recycling management systems - Diagrams to show the location of hazardous materials onboard ships - specifies how to prepare diagrams that clearly show where hazardous materials are located on a ship. These diagrams support the Inventory of Hazardous Materials (IHM) required by the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships (2009) and follow IMO guidance (MEPC.179(59)). ISO 30006:2010 helps shipowners, ship recyclers and inventory preparers produce consistent, traceable visual documentation for safe, compliant ship recycling.
Key topics and requirements
- Scope and references
- Diagrams cover hazardous items listed in Appendix 1 of the Hong Kong Convention and follow IMO guidelines.
- Target materials
- Include coating systems, equipment, machinery, structures and hull components containing hazardous materials (e.g., asbestos, PCBs as cited in the standard).
- Timing and maintenance
- Diagrams must be developed when Part I of the inventory is prepared and maintained/updated regularly to remain consistent with the inventory.
- Plans and drawings
- Use general arrangement, engine room arrangement, accommodation and tank arrangement plans.
- Electronic, scalable drawings are recommended for clarity and legibility.
- Presentation and linking
- Each hazardous item on the diagram must show the inventory number, equipment name and material name.
- Use a red frame and red colouring to identify hazardous locations for quick recognition.
- Sampling points
- When developing inventories for existing ships, clearly mark sampling points and, where available, include visual-check results.
- Items not illustrated
- Some listed materials (e.g., electric cables, pipes) need not be shown graphically but must be listed in an attached table to avoid omission.
Practical applications and users
- Primary users:
- Shipowners preparing IHMs, ship recycling yards, marine surveyors, classification societies, and regulatory compliance teams.
- Benefits:
- Streamlines ship recycling planning and risk assessment.
- Supports regulatory compliance with the Hong Kong Convention and IMO guidelines.
- Improves safety for workers and reduces environmental risks by making hazardous-material locations unambiguous.
- Typical use cases:
- Preparing or auditing an IHM, planning dismantling and waste segregation, visual inspection and sampling during ship surveys.
