Which term describes the principle and procedure requiring reporting to authorities when an accident or incident involving dangerous goods occurs?

• A. Dangerous Goods Reporting
• B. Hazardous Materials Communications Protocol
• C. Accident and Incident Reporting
• D. Incident Investigation and Reporting

Answer: (C)

The main idea being tested is the formal obligation to report any accident or incident involving dangerous goods to the appropriate authorities. The term Accident and Incident Reporting is the best fit because it explicitly describes both types of events and the required action: notifying the competent authority. This phrasing is how regulators and industry texts frame the duty to report, so it covers not just what happened but the mandated step to inform those who oversee safety.

Reporting serves to maintain safety oversight: it allows authorities to assess the incident, monitor compliance, identify causes, and take corrective actions to prevent recurrence. In practice, the report usually includes key details such as the nature of the event, the dangerous goods involved (shipping name, UN number, class, quantity), packaging and handling information, location and time, and any injuries or exposures. The report is submitted to the national competent authority or another designated authority, following specified timeframes and formats.

Other terms don’t fit as well because they either describe a broader or different activity (like general reporting of dangerous goods without the formal obligation to authorities), focus on the investigation rather than the initial reporting to authorities, or refer to a protocol or process not specifically tied to official reporting requirements.
