"Appendix H" Now a Standalone Document

Appendix H to the IATA DGR, which provided guidance for employers about a competency-based approach to dangerous goods training, has been removed for the 2023 edition. The guidance about competency-based training is now available as a standalone document.

A competency-based approach to dangerous goods training is one that identifies key competencies and skills that each employee will need and provides training and tools for the employee to develop these competencies.

49 CFR and IATA DGR Training

To help employers implement a competency-based approach to dangerous goods training, Lion offers a variety of online 49 CFR (US DOT) and IATA DGR training courses that address specific job functions that hazmat employees may perform—such as classifying and naming materials, packaging, marking, labeling, placarding, loading, unloading, and documenting hazmat shipments.
