SECTION GUIDE

What is Accident Investigation?

Accident investigation is the structured process of examining workplace incidents, near misses, or accidents to determine their causes and prevent future occurrences. It focuses on fact-finding, not fault-finding, and is a key part of an employer’s duty to provide a safe workplace.

What does Accident Investigation mean in Health & Safety?

In the UK, employers have a legal duty under the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999 to investigate workplace accidents. Some incidents must also be reported to the HSE under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013).
Accident investigations typically involve:

  • Collecting evidence (witness statements, photographs, equipment checks)
  • Identifying immediate and root causes
  • Reviewing risk assessments and safe systems of work
  • Making recommendations for corrective action

  • Why does Accident Investigation matter for your business?

    Ignoring or poorly handling accidents can lead to:

    • Repeat incidents and ongoing safety risks
    • Enforcement action
    • Employee claims for personal injury or negligence
    • Reputational damage with clients, stakeholders and staff

    A robust accident investigation process helps prevent recurrence, demonstrates compliance, and promotes a strong safety culture.
