Which type of event signals a potential danger but does not result in injury, as per RIDDOR guidelines?

The correct choice is dangerous occurrences because this term specifically refers to events that could lead to significant harm or injury but have not resulted in any actual injury or damage at that moment. According to RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations), a dangerous occurrence is defined as an event that has the potential to cause harm, highlighting the risk factors present in a workplace without anyone being injured.

In contrast, major injuries indicate actual harm that has occurred, and minor injuries refer to less severe injuries that do result in a medical need, though they are not life-threatening. Work-related diseases involve actual health conditions caused by work activities, which again indicates that injury or illness has occurred. Dangerous occurrences are therefore unique in that they emphasize the risk and potential for injury without resulting in an actual incident, making this choice the appropriate answer.
