A Certified Dangerous Goods Professional® (CDGP®) is a professional involved in the transport of goods and materials that have been categorized as regulated materials and have special packaging, communication, and transport requirements. The CDGP is a person who is an expert in appreciating the potential hazards and the complexity of the regulations that apply to them, and who can accurately analyze the requirements for dangerous goods transport through his or her use of regulatory reference sources. A CDGP is competent in:

• International regulatory requirements and standards relevant to the transport of dangerous goods

• Understanding the training requirements, the terms, phrases and definitions for the transportation of dangerous goods

• Interrelationships between international regulatory requirements, standards and associated updates

• Understanding special permits, competent authority approvals, and/or agreements and certificates

• The identification, classification, packaging, marking, labeling/placarding, documenting, handling/loading/unloading, stowage, segregation, security and emergency response for dangerous goods

• The use of special provisions and exceptions

• Emergency Planning, Emergency Information, Incident reporting: What is required, when it is required and to whom it must be reported, the use of salvage packaging, repackaging and prohibitions on salvage packaging

• When site specific security plans are needed, and their training requirements, key issues to consider when developing security procedures for personnel, and key issues to consider when developing security procedures for travel routes.

Although it may seem obvious, because a CDGP is an unbiased verification that a company employs a global expert in handling hazardous materials and dangerous goods, that CDGP can help the company demonstrate to suppliers, customers, and regulatory/law enforcement, that they don’t just meet the minimum requirements, but that they excel at compliance and safety.  Inspectors like to see this, and more and more often these days, prospective customers and business partners find a corporate culture that promotes safety and health to be an advantage.  Having employees with CDGPs is a clear way to display that culture and competitive advantage.
