In recent years, there has been a rapid growth in the transport and storage of hazardous and noxious substances (HNS). If allowed to escape, these materials can present a danger to a ship’s crew, the vessel, coastal populations and/or the environment. Accordingly, public concern over these materials has grown, and both Governments and industry have taken steps to address and respond to such incidents.

Marine spills involving HNS are not as frequent as oil spills, and may receive little publicity due to their less visible nature. However, on a global basis, marine spills involving HNS are not rare. In fact, a worldwide survey of marine HNS emergencies showed that:

  • there is a wide range of cargoes which need to be considered as potential threats;

  • most accidents involved mainly two classes of HNS: flammable liquids and corrosive materials;

  • one to two major HNS accidents can be expected each year;

  • a wide variety of ship types were associated with HNS accidents; and

  • HNS accidents were almost equally divided between ‘‘bulk’’ and ‘‘packaged goods’’ shipments.

6.10 Summary of measures

A​​s a specialized agency of the United Nations, IMO is the global standard-setting authority for the safety, security and environmental performance of international shipping. Its main role is to create a regulatory framework for the shipping industry that is fair and effective, universally adopted and universally implemented.  

In other words, its role is to create a level playing-field so that ship operators cannot address their financial issues by simply cutting corners and compromising on safety, security and environmental performance. This approach also encourages innovation and efficiency.

Shipping is a truly international industry, and it can only operate effectively if the regulations and standards are themselves agreed, adopted and implemented on an international basis. And IMO is the forum at which this process takes place.
