What is Inventory of Hazardous Materials (IHM)

The maritime industry is familiar with hazardous material being managed onboard daily, navigating crew exposure, and minimizing potential risk in the ship environment. A proper maritime manager needs to ensure that the materials are properly recorded to reduce the potential liability for ship owners.

Inventory of Hazardous Materials, commonly referred to as IHM, is a concept that significantly benefits ship owners in their maintenance and management of hazardous materials; the idea includes detailing out the quantities, types, and locations of hazardous materials that are onboard the vessels. To comply with the European Union Ship Recycling Regulation guideline and the Hong Kong Convention for the Safe and Environmentally Sound Recycling of Ships, ship management personnel must report on a comprehensive and accurate inventory of hazardous materials. Given the deadline for this reporting responsibility, you must explore what this will mean for you. 

How Can You Ensure You Are Complying with IHM? 

3 Steps on Optimum IHM Compliance

  1. Prepare for the Deadline of the IHM Compliance 

IHM compliance is an initially daunting and time-consuming process that can take anywhere up to 3 months. The EU SRR was adopted about seven years ago, and the Covid-19 pandemic imposed an unexpected 6-month delay in the workflows. However, the end of 2020 brought the novel regulation that any ship 500 GT and over, irrespective of the flagship, will require the IHM certification onboard on a European Union port and anchorage. This also applies to vessels that do not have the EU flag, as they also require certification in compliance with the HKC IHM regulations. 

The Inventory of Hazardous Material includes three domains: 

  • Hazardous materials that are a part of the ship structure and equipment

  • Waste that is operationally generated

  • Stores
