Which of the following injuries must be reported under RIDDOR?

The requirement to report an injury under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) focuses on significant injuries that could impact a person's health or their ability to work. A fracture of the pelvis is classified as a major injury, which falls under the list of reportable injuries due to its seriousness and potential long-term implications for an individual's health and mobility.

In the context of workplace safety, major injuries are those that could lead to severe consequences for an employee, necessitating that they be documented and reported to ensure that proper investigations can be carried out and that preventive measures can be implemented. Fractures, specifically those to significant areas such as the pelvis, are critical because they often require extensive medical care and render an individual incapable of working for a substantial period.

While minor cuts and bruises, sprains and strains, and headaches might cause discomfort or temporary incapacity, they generally do not meet the threshold for RIDDOR reporting unless they lead to more serious health complications or persistent issues. Therefore, the need to report a fracture of the pelvis underscores the regulations' focus on major injuries that can have a more profound effect on an employee's health and the workplace as a whole.
