NEBOSH HSE Introduction to Incident Investigation


NEBOSH and the HSE have joined forces to develop a new one day qualification that shows how non-complex incidents can be investigated effectively.

Learning to investigate incidents is a vital skill as it can help you to make improvements to your health and safety so that your organisation can avoid similar incidents occurring in the future, positively impacting the safety culture of a workplace.

After completion of this NEBOSH qualification, you can progress on to other courses, such as the NEBOSH National General Certificate in Occupational Health or the NEBOSH Health and Safety at Work Qualification.

  • investigate simple incidents as well as ones more large scale -carry out risk assessments and help resolve incidents using investigation techniques
  • come up with an action plan to prevent incidents from reoccurring
  • gather evidence and contribute to team investigations, including conducting witness interviews

Employers, supervisors, union and safety representatives will benefit greatly from this incident investigation course.

Employers will gain a number of benefits from giving their staff the opportunity to take this qualification, including:

  • Drives down repeat incidents – learn lessons from investigating cause
  • Confidence that your organisation’s approach to investigations is robust
  • Impact the safety culture by encouraging a proactive approach to incident investigation
  • Build in-company expertise
  • An approach to incident investigation that reflects best practice
  • A qualification created by both NEBOSH and HSE


This one day course covers the following topics:

  • Moral, legal and financial arguments for investigations, including both minor incidents and some more large scale
  • Human and organisational factors that can contribute to an incident
  • The process for investigating incidents and building environmental awareness
  • Positive interview strategies and the barriers to successful interviews

A practical assessment INV1 is completed at the end of the course. You will be provided with a pack of evidence and shown a video of three witness interviews. You will be asked to review the evidence, evaluate each interview and produce an action plan that will help prevent a recurrence of an incident.

Course dates vary between course providers and are held in different training centres.
While there are no entry requirements, it is recommended that those taking the HSE Introduction to Incident qualification should already have a basic foundation of health and safety. Usually, many students taking this course would have previously taken another accredited course in safety management, such as other NEBOSH diplomas.
You will receive your NEBOSH HSE results 24 working days of sitting the assessments. Once you have achieved a pass your Introduction to Incident Investigation qualification parchment will be issued. This is normally within 40 working days of the confirmation of your results.
