Accident Investigation
Find out what happened, who was hurt, whether it is reportable, and what will stop it happening again.
Investigation is wider than RIDDOR. You should look at accidents, specified injuries, occupational disease, dangerous occurrences and near misses that teach you something. The legal reporting duty is narrower: only certain events must be notified to HSE or the local authority, in set timescales. Leemarda Safety hosts the investigation, the RIDDOR decision, and the actions, so the file is complete if an inspector asks.
Ask Leemarda to do this for youWhat the law requires
- RIDDOR 2013: the responsible person (usually the employer) must report work-related deaths, specified injuries, over-seven-day incapacitation of a worker, certain occupational diseases, and listed dangerous occurrences.
- Most reports are made online. Fatalities and specified injuries to workers can also be phoned to HSE on 0345 300 9923. Over-seven-day injuries must be notified within 15 days. Other reportable incidents should be notified without delay and in any event within 10 days.
- You must keep a record of reportable events, and of occupational accidents that cause more than three consecutive days off work even when those three-day injuries are not themselves reportable.
Official guidance
- RIDDOR is a reporting law. It does not replace your duty under HSWA and the Management Regulations to investigate and put controls right. HSE does not investigate every report.
