SECTION GUIDE

What is Critical Incident Reporting?

Critical incident reporting is the formal process of recording and responding to serious or unexpected events in the workplace that cause, or could cause, significant harm to people, property, or business operations. These incidents go beyond minor accidents and usually require immediate action, investigation, and regulatory reporting.

  • What does Critical Incident Reporting mean in Health & Safety?

    In the UK, certain serious incidents must be reported to the Health and Safety Executive (HSE) under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013). These include fatalities, major injuries, dangerous occurrences, and occupational diseases.

    Examples of critical incidents include:

    • Workplace fatalities or life-threatening injuries
    • Fires, explosions, or chemical spills
    • Collapses of structures or major equipment failures
    • Violence or security breaches at work
    • Events requiring emergency services attendance

    Critical incident reporting ensures compliance, helps prevent recurrence, and protects employees by addressing root causes quickly.

  • Why does Critical Incident Reporting matter for your Business?

    Failing to report and manage critical incidents can result in:

    • Legal penalties and potential prosecution under HSE law
    • Civil claims for negligence or personal injury
    • Long-term reputational damage with staff, clients, and regulators
    • Loss of employee trust and reduced engagement

    Conversely, a strong reporting culture demonstrates transparency, responsibility, and care for employee wellbeing.

    Any serious, unexpected event that causes or could cause significant harm — such as a fatality, serious injury, fire, or dangerous occurrence.

    Certain incidents must be reported without delay, and fatal or major injuries must be reported within 10 days under RIDDOR.

    Employers and duty holders have legal responsibility, but line managers and supervisors must ensure incidents are reported promptly through internal systems.

    Yes. Critical incidents may also include traumatic events, such as workplace violence, which can have long-term psychological effects on employees.
