In some cases, workplace violence can be reportable if it happens during work and without consent.
Reportable Deaths Under RIDDOR
Under RIDDOR, you must report all work-related deaths. This rule applies to both workers and people who are not workers, like visitors or members of the public. However, RIDDOR does not include suicide in its reporting rules.

An over-7-day injury happens when a worker cannot do their normal job because of an injury at work. This situation continues for more than 7 days in a row. This includes weekends and rest days as well. However, the day the accident happens does not count in these 7 days.
In simple terms, the worker must stay away from their normal duties due to the injury. Even if they return to light duties, it may still count if they cannot do their usual work.
Important Over-7-Day Injury Rules
First, if the worker is away from normal work for more than 7 consecutive days you must report it. Next, you must report it within 15 days of the accident. Finally, remember that light duties can still count if the worker cannot do their normal job properly.
What are the Over-3-Day Injuries?
Sometimes a workplace injury is not serious enough to report under RIDDOR. For example, if a worker cannot do their normal job for more than 3 days. You do not need to report it to the authorities. However, you still must record it properly inside your workplace records. This helps you keep track of all accidents and stay safe in the future.
Over-3-Day Injury Rules
If someone stays off work for more than 3 days in a row. You only need to record it in the accident book. You do not send a RIDDOR report at this stage. However, if the absence goes beyond 7 days, then it becomes reportable under RIDDOR.
What is a Dangerous Occurrence Under RIDDOR?
A dangerous occurrence under RIDDOR is a serious “near miss” at work. It means something went wrong, but no one may have been hurt. However, it still had the chance to cause serious harm. So, the law says you must report it even if there is no injury.
