Inventory of Hazardous Materials (IHM)

31 December 2018 is coming into general application the EU Ship Recycling Regulation (EU SRR 1257/2013).

In accordance with this Regulation vessels are required to have a certified IHM (Inventory Hazardous Material).

Each ship shall have on board an inventory of hazardous materials, which shall identify at least the hazardous materials contained in the structure or equipment of the ship, their location and approximate quantities.

The IHM should be developed in accordance with requirements of following normative documents:

  • Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships (2009 – SR/CONF/45)
  • Guidelines for the Development of the Ship Recycling Plan
    (2011 - MEPC.196(62))
  • Guidelines for the Safe and Environmentally Sound Ship Recycling
    (2012 - MEPC.210(63))
  • Guidelines for the Authorization of Ship Recycling Facilities
    (2012 - MEPC.211(63))
  • Guidelines for the survey and certification of ships under the Hong Kong Convention (2012 - MEPC.222(64))
  • Guidelines for the inspection of ships under the Hong Kong Convention
    (2012 - MEPC.223(64))
  • Guidelines for the Development of the Inventory of Hazardous Materials
    (2015 - MEPC.269(68))
  • Regulation (EU) No. 1257/2013 of the European Parliament and of the Council
    of 20 November 2013 on Ship Recycling
  • EC Technical guidance note: Requirements and procedure for inclusion
    of facilities located in third countries in the European List of ship recycling facilities

The IHM should consist of:

Part I:         Materials contained in ship structure or equipment;

Part II:        Operationally generated wastes;

Part III:       Stores.

DNVGL-Knowing what's inside Your ship

Each item is classified under tables A, B, C or D, according to its properties:

.1 table A comprises the materials listed in appendix 1 of the Convention:

Table A

.2 table B comprises the materials listed in appendix 2 of the Convention:

Table В

.3 table C (Potentially hazardous items) comprises items which are potentially hazardous to the environment and human health at ship recycling facilities:

Table C

.4 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:

Table D

Standard format of the Inventory of Hazardous Materials is presented below:

Part I

Part II

Part III

In order to achieve comparable results for existing ships with respect to Part I of the IHM, the following procedure should be followed:

.1         collection of necessary information;

.2         assessment of collected information;

.3         preparation of visual/sampling check plan;

.4         onboard visual check and sampling check;

.5         preparation of Part I of the Inventory and related documentation.

Flow diagram for developing Part I of the IHM for existing ships is presented below:


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:
