The International Maritime Dangerous Goods (IMDG) Code was first published by the International Maritime Organization (IMO) in 1965 and is now updated every two years. As of January 2004, the Code has been mandatory for the International Convention for the Safety of Life at Sea (SOLAS) signatory states, effectively making it a global rulebook for the sea transport of Dangerous Goods.

Although it is directed primarily at sea transport, the provisions of the Code may affect a whole range of industries and services. Manufacturers, packers, shippers, feeder services such as road and rail and port authorities will find authoritative advice on classification, stowage, segregation, packing, labelling, terminology and emergency response action.

In addition to publishing the printed version of the Code, IMO has produced the electronic versions to meet the need for fast, accurate information retrieval and to cater for the differing needs of users.

5. What are the differences between IMDG Code for Windows, IMDG Code on the Web and IMDG Code for Intranet?

There are two main factors that should help you decide which product suits your requirements:

  • Number of anticipated users
  • Method of access (e.g., via the internet)

IMDG Code for Windows (ZL200E)
This the ideal solution for single users who need frequent and guaranteed access. IMDG Code for Windows is a stand-alone product installed locally on your computer, either via download or installed from a CD. Once it is installed, internet access is not required.

Each computer on which it is installed must be licenced and is activated with an activation code. For ease of maintenance and updating, the product can be installed a shared network and accessed by multiple users, but each networked computer requires a unique activation code.

IMDG Code for Intranet (DJ201E)
In some cases, the method of access will be the main criterion for determining which product meets the requirements of your organisation. For example, if you are a medium sized business/large organisation and your end users have no internet access, you may consider hosting the IMDG Code on your own intranet server.

IMDG Code on the Web (S200E)
For occasional use from any location, provided an internet connection is present, IMDG Code on the Web provides an economical way of accessing the IMDG Code. Several users can share the same “username”, but only one user at a time.
