What does RIDDOR mean in HR and Health & Safety?

From an HR and health and safety perspective, RIDDOR provides a clear framework for reporting work-related incidents. It is not intended to cover every workplace accident but focuses on those that are serious, unusual, or have the potential to highlight systemic risks.

Examples of reportable events include:

• Work-related deaths – if an employee, contractor, or member of the public dies as a result of a workplace accident.
• Specified injuries – including fractures (excluding fingers and toes), amputations, loss of sight, or serious burns.
• Occupational diseases – such as carpal tunnel syndrome, occupational asthma, or dermatitis that develop due to workplace exposure.
• Dangerous occurrences – “near misses”, where something goes seriously wrong (e.g. the collapse of lifting equipment or accidental explosions), even if no one is hurt.
• Incidents involving the public – for example, if a customer slips due to a workplace hazard and requires hospital treatment.

RIDDOR applies across industries, from offices and retail premises to construction sites and manufacturing plants.

Why does RIDDOR matter for Your organisation?

For employers and organisation leaders, compliance with RIDDOR is both a legal requirement and a moral responsibility. Failing to report incidents can have wide-ranging consequences.

• Legal compliance – Failure to report under RIDDOR can result in enforcement action, investigations, and substantial fines. In some cases, prosecutions can lead to criminal liability for directors or managers.
• Reputation and trust – Employers that are seen to take health and safety seriously gain trust from employees, customers, and stakeholders. Conversely, ignoring duties can quickly damage brand reputation.
• Employee engagement – When employees see that their wellbeing is taken seriously and that incidents are reported and acted upon, it helps build trust, reduce employee turnover, and create a safer working culture.
• Prevention of repeat incidents – Reporting is not just about compliance. It also provides valuable insight into the root causes of accidents, allowing businesses to put better controls in place.

In short, RIDDOR helps create safer workplaces. For SMEs in particular, demonstrating compliance is vital to avoid disruption, financial penalties, and reputational harm.

RIDDOR Best Practices and H&S Guidelines

To meet your RIDDOR obligations effectively:

• Understand the scope – Familiarise yourself and your managers with what is considered “reportable” under the regulations. Not all accidents qualify, but the serious ones must never be overlooked.
• Clarify responsibility – Employers, site managers, agencies, and self-employed workers all have duties under RIDDOR. Make sure contracts and policies clearly state who is responsible for reporting.
• Record everything properly – Use an accident book or HR/H&S system to log all incidents, even those not reportable (such as over-3-day incapacitations). Accurate records protect your business if questions arise later.
• Provide training – Managers and supervisors should be trained to recognise reportable events and know how to escalate them quickly.
• Act promptly – Reports should be made without delay. For example, over-7-day incapacitations must be reported within 15 days of the incident.
• Review and learn – Use reported incidents as an opportunity to improve policies, carry out risk assessments, and prevent recurrence.
