Product Details

Anyone having a job function which could in any way affect the safe transportation of dangerous goods, by any mode of transportation, is required by Federal and international regulations to undergo appropriate training. The regulations for shipping dangerous goods by vessel are particularly stringent, as a dangerous goods incident occurring on the seas can be far removed from emergency response assistance. Hazardous materials incidents that occur at sea also pose a serious threat of an environmental catastrophe that can immeasurably devastate aquatic life.

In an effort to prevent incidents and accidents from occurring, hazmat employees involved in the vessel transport process must comply with initial or recurrent training and strict regulations for the classification, identification, packing, marking and labeling, documentation, placarding, and segregation of hazardous materials. They must know which types of dangerous goods are outright forbidden from being transported, and those that are only allowed under certain conditions and in certain amounts.

Where authorized, the Limited Quantities provisions of the International Maritime Dangerous Goods Code (IMDG Code) provide an alternative method of shipping specific small quantities of certain substances, allowing for the use of packagings that are less stringently tested than those required for larger quantities, as well as relief from certain marking and labeling requirements. Because of this, the Limited Quantities provisions, if chosen to be used, provide significant cost savings to shippers while ensuring their shipments maintain compliance with those regulatory requirements that remain applicable.

Hazmat University’s limited quantities hazmat training course  provides hazmat training to participants involved with shipping, handling, and/or transport of dangerous goods in Limited Quantities by vessel. It may be completed as a standalone course by those involved with vessel transport of dangerous goods in Limited Quantities only, or it may be completed as a supplement to a more comprehensive training in the transport of dangerous goods by vessel, in order to enhance function-specific knowledge regarding Limited Quantities. This course is based on the requirements outlined in the International Maritime Dangerous Goods Code (IMDG Code). Additionally, this course complies with the initial and/or recurrent limited quantities hazmat training requirements of 49 CFR Part 172, Subpart H, Section 172.704 and the IMDG Code for transportation of Limited Quantities by vessel.

Included in this course at no additional cost are General Awareness and Security Awareness.

Employees who have undergone initial or recurrent limited quantities hazmat training in the past are required by law to undergo recurrent limited quantities hazmat training at least once every three years according to 49 CFR and the IMDG Code.
