This section of the website looks at which of the incidents - that are reported to the HSE as the Reporting of Injuries, deaths and Dangerous Occurrences Regulations(RIDDOR) - are investigated.

It should be noted that simply because an incident is not 'formally reportable' does not necessarily mean that the HSE will not investigate it. If the HSE is informed about a death or an injury which involves some significant safety issues which is not being dealt with by any other agency, it may well use its dicretion to investigate. This could for example happen in relation to a death or injury resulting from a Road Traffic Incident or from an operation in a hospital - most of which are not formally reportable.to the HSE under RIDDOR

In addition, whilst a suicide is not reportable, it could be subject to an HSE investigation if there was evidence that a reson for the suicide was stress or bullying that took place at the workplace.
