Which statement best describes the scope of documentation retention described in incident procedures?

• A. Only the Shipper's Declaration needs to be kept
• B. Only Emergency Response Information needs to be kept
• C. Only documentation related to packaging needs to be kept
• D. All DG documentation, including Shipper's Declaration and Emergency Response Information, should be maintained

Answer: (D)

The main idea here is that incident procedures require having complete information about any dangerous goods involved, not just parts of it. Keeping all DG documentation ensures you can accurately identify what was shipped, who prepared it, how it’s classified, and what emergency measures are needed. The Shipper's Declaration records the essential details about the contents, classification, and packaging, while the Emergency Response Information provides step-by-step actions for responders in case of an incident. Together, they give a full picture: what’s in the package, how dangerous it is, and how to respond safely. If you only retain one type, you’d lose critical context for risk assessment, proper containment, and communication with authorities. That’s why maintaining all DG documentation, including both the Shipper's Declaration and Emergency Response Information, is the correct approach.
