Course Description:

EHS/aquatic toxicity criteria are used for transport classifications in DG regulations around the world, including the UN Model Regulations, ICAO Technical Instructions/IATA DGR, Canadian TDGR, ADR, and serve as the principal element in the classification of Marine Pollutants under the IMDG Code. This webinar will offer a deep dive into the UN classification criteria for Environmentally Hazardous Substances (aquatic environment), most commonly shipped as UN3082/UN3077.


Webinar Content

The webinar will cover criteria and methods for the classification of substances, criteria and methods for the classification of mixtures (including the summation method and M factors), an explanation of the types of data needed for making classification decisions, and recommendations for sources of data. A brief overview of the alternative U.S. approach to classifying environmental hazards (i.e., hazardous substances and marine pollutants) will be also be provided.


Webinar Methodology

The webinar will feature explanations of the criteria with accompanying examples for illustration, will make extensive use of practice exercises, including finding and using data from external sources, and will offer several Q & A sessions.
