DGR (Dangerous Goods Regulations) Training

Lesson 1 • Core Terminology and Definitions

Defines essential terms used throughout all DGR documentation and training. Precise vocabulary prevents misclassification and compliance errors.

Lesson 2 • General Principles of DGR Compliance

Outlines the duty-of-care obligations shared among all parties in the transport chain. Establishes the compliance mindset required before applying specific rules.

Lesson 3 • Key Regulatory Bodies and Documents

Identifies the organizations that publish and enforce dangerous goods rules across air, sea, road, and rail. Connects each body's authority to the documents professionals use daily.

Lesson 1 • Multiple Hazards and Subsidiary Risks

Addresses substances that present more than one hazard and require a primary and subsidiary classification. Students learn precedence rules to determine the correct primary class.

Lesson 2 • The Nine Hazard Classes Overview

Introduces each hazard class by its defining physical or chemical property and associated risk. Provides the mental map needed to navigate classification tables efficiently.

Lesson 3 • Using the Dangerous Goods List

Guides students through the master list of dangerous goods entries to locate UN numbers, proper shipping names, and associated data. Efficient list navigation is essential for every shipment.

Lesson 4 • Classification Criteria and Tests

Explains the physical, chemical, and biological criteria used to assign a hazard class. Links test methods to classification outcomes for practical application.

Lesson 1 • Excepted and Limited Quantity Packaging

Explains the simplified packaging rules that apply to small quantities of certain dangerous goods. Students identify when these provisions apply and what reduced requirements are permitted.

Lesson 2 • Inner, Outer, and Combination Packaging

Distinguishes between single, combination, and composite packaging configurations and their appropriate uses. Correct configuration selection prevents containment failures during transport.

Lesson 3 • UN Specification Marking System

Decodes the alphanumeric UN specification mark printed on approved packaging. Students can verify that a package is authorized for a specific dangerous good.

Lesson 4 • Packaging Design and Performance Standards

Describes the engineering standards that packaging must meet before it may be used for dangerous goods. Links design requirements to the hazard class and packing group of the contents.

Lesson 1 • Hazard Labels: Design and Placement

Describes the standardized diamond-shaped labels assigned to each hazard class and division. Correct label selection and placement are legally required and safety-critical.

Lesson 2 • Handling Labels and Special Marks

Covers orientation arrows, cryogenic labels, elevated temperature marks, and other supplementary indicators. These marks communicate handling instructions beyond basic hazard identification.

Lesson 3 • Package Marking Requirements

Specifies the text-based information that must appear on the outside of every dangerous goods package. Accurate marking enables handlers and emergency responders to identify contents quickly.

Lesson 1 • Road and Rail Transport Documents

Covers the transport document requirements specific to road and rail modes. Students distinguish modal differences in documentation format and content.

Lesson 2 • Document Verification and Error Correction

Provides a systematic method for checking completed documents against regulatory requirements. Students identify common errors and apply correct amendment procedures.

Lesson 3 • The Shipper's Declaration

Details the mandatory declaration that the consignor must complete and sign for every dangerous goods shipment. Errors on this document are among the most common compliance failures.

Lesson 4 • Sea Transport Documentation

Addresses the dangerous goods declaration and container packing certificate required for maritime shipments. These documents are critical for port acceptance and vessel stowage planning.

Lesson 1 • Storage Requirements by Hazard Class

Specifies the environmental and structural conditions required to store each hazard class safely. Improper storage is a leading cause of warehouse incidents involving dangerous goods.

Lesson 2 • Safe Handling Principles

Establishes the physical handling practices that minimize risk when moving dangerous goods packages. Connects handling technique to the specific hazard properties of each class.

Lesson 3 • Loading and Unloading Procedures

Covers the sequence and precautions required when loading dangerous goods onto or off transport vehicles. Correct loading prevents shifting, damage, and incompatibility incidents in transit.

Lesson 1 • Incident Reporting and Investigation

Explains the mandatory reporting obligations following a dangerous goods incident and the investigation process. Accurate reporting drives systemic safety improvements.

Lesson 2 • Recognizing a Dangerous Goods Incident

Teaches the visual and sensory indicators that signal a dangerous goods release or emergency. Early recognition reduces exposure time and enables faster protective action.

Lesson 3 • Spill Containment and Cleanup

Covers the methods and materials used to contain and neutralize dangerous goods releases. Students understand the limits of their role versus that of specialist responders.

Lesson 4 • Immediate Response Actions

Defines the priority actions to take in the first minutes of a dangerous goods incident. These actions protect life, limit exposure, and preserve evidence for investigation.

Lesson 1 • Sea Transport Specific Requirements

Covers the stowage, segregation, and firefighting requirements unique to maritime dangerous goods transport. Vessel stability and container integrity are central concerns.

Lesson 2 • Road and Rail Specific Requirements

Addresses the vehicle construction, driver training, and route restriction requirements for land transport. Students apply tunnel and population zone restrictions to route planning.

Lesson 3 • Multi-Modal Shipment Planning

Guides students through the compliance challenges of shipments that cross multiple transport modes. The most restrictive modal rule governs when requirements conflict.

Lesson 4 • Air Transport Specific Requirements

Details the most restrictive dangerous goods rules applied to passenger and cargo aircraft. Air regulations impose unique quantity limits, forbidden goods lists, and operator variations.

Lesson 5 • Compliance Auditing and Continuous Improvement

Equips students to conduct internal DGR compliance audits and build a culture of continuous improvement. Systematic auditing prevents regulatory violations and reduces incident risk.
