Learn More About IMDG Online Training

There are a number of important regulations and requirements to adhere to when shipping dangerous goods by vessel. These laws and regulations are governed by, and codified in, the International Maritime Dangerous Goods Code, also known as the IMDG Code. This is in addition to Title 49, Code of Federal Regulations (49 CFR), specifically the section known as the Hazardous Materials Regulations (HMR) if shipping to, from, and within the U.S. and its territories. While the main purpose of these regulations is to ensure crew member safety during the transportation of dangerous goods by vessel, they also serve to help mitigate marine pollution.

The International Maritime Organization (IMO) maintains strict regulation of how dangerous goods can be shipped by sea. This applies to hazmat employees involved in any part of the shipping process, from those who document, package, and/or oversee the safety of entire vessels.

This means that being properly trained in the transport of dangerous goods by vessel not only improves the safety and efficiency of your organization, which leads to a decrease in wasted time and resources and an increase in revenue, but it is also vital to preventing fines for lack of compliance, thereby emphasizing the necessity of IMDG certification training.

Hazmat University is proud to offer IMDG certification training that complies with the training requirements for IMDG certification training. This course covers the proper classification, identification, documentation, packing, marking and labeling, placarding, segregation, safety, and security of dangerous goods to be transported by vessel, and satisfies both the initial and recurrent training requirements set forth in the regulations.

Our IMDG certification training allows hazmat employees to quickly and easily become IMDG-trained or to seamlessly maintain their certification. This means instant proof of course completion and no lag between an employee becoming certified and starting or continuing to handle dangerous goods.

If you are involved in the handling, shipping and or transport of lithium batteries, it is highly recommended that you also purchase our Supplemental Lithium Batteries Training, which is available in this store. It is the employer’s responsibility to ensure their employees are trained commensurate with their responsibilities, which may necessitate additional training.

Note: This course is based on the IMDG 2022 Edition, and it is recommended that you have this manual on hand when taking this course.  For further information, please call our office at (844) 532-7634.
