What type of injuries do NOT need to be reported under RIDDOR?

The correct answer is that minor injuries that require first aid treatment do not need to be reported under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations). RIDDOR sets out specific criteria for which injuries must be reported, focusing primarily on more serious incidents that have a significant impact on health and safety. Minor injuries, such as cuts or bruises that are treated with first aid and do not result in further complications, fall outside of the reporting requirements because they do not pose a significant risk to the individual's health or safety, nor do they indicate a larger safety issue in the workplace.

Other options mentioned, such as injuries that occur outside of work hours, injuries to contractors, and veteran-related stress injuries, may still have reporting obligations under different criteria or circumstances, but minor first aid treatments are explicitly excluded under RIDDOR regulations. This distinction is crucial for ensuring that only serious incidents are escalated for further investigation and reporting, maintaining a focus on significant health and safety concerns in the workplace.
