Shipping dangerous goods presents safety issues that must be addressed. The International Maritime Dangerous Goods (IMDG) Code was developed to help ensure dangerous goods are transported safely by sea. Its regulations provide the individuals who handle and ship dangerous goods with the information they need to do so safely. This course begins with an introduction to the IMDG Code, including its origins, purpose, and enforcement and training requirements. In the United States, the Pipeline and Hazardous Materials Safety Administration (PHMSA) develops and enforces regulations for the safe transport of dangerous materials. The connection between the two sets of regulations will be explained. A physical description of the IMDG Code is given, as well as instruction on how to access and use the information it contains to determine if dangerous goods are regulated by IMDG and PHMSA and how to ship them properly.
This course was developed with subject matter support provided by EnSafe Inc., a global professional services company focusing on engineering, environment, health and safety, and information technology.
