Presuming that you are referring to your internal company recording/reporting system that uses OSHA criteria, yes. OSHA Criteria are more strict/prescriptive compared to RIDDOR. For OSHA, you do not include the day of the accident -similar to RIDDOR.

It would help us with an answer if we had more background to the reasons for the questions. Jay points top the answer, I think. This is my attempt RIDDOR (Injury) Reporting categories are deaths; major injuries; over-3-day injuries – where an employee or self-employed person is away from work or unable to perform their normal work duties for more than 3 consecutive days; injuries to members of the public or people not at work where they are taken from the scene of an accident to hospital; Note it mentions "over 3 day injuries" this includes restricted work day cases. OSHA (Injury) reporting categories are Medical Treatment Cases, Restricted Work Day Cases, Days Away from Work Cases (LTIs), these are all classed as Recordable Injuries. other categories are First Aid Cases and Fatals. Nb we are only covering injuries Many organisations today use the OSHA Standard for recording injuries so that they can benchmark against other international companies or are themselves an international company. They still need to comply with RIDDOR in the UK. My guess is that the question refers to an international organisation. Hope this helps Steve

As others have said it entirely depends on what classification system you are classifying it within. Is it your internal company system? Is it based on OSHA? RIDDOR does not include these classifications of restricted work or lost time (it's just "over three days" regardless), nor tell you how to classify injuries for your internal company statistics. That's entirely up to your company.
