Course overview

Accidents can occur in even the safest, best-run and most compliant workplaces. The one-day NEBOSH HSE Introduction to Incident Investigation course provides the range of skills needed to conduct an unaided investigation of non-complex health and safety incidents — also enabling candidates to work as part of a team on larger, more complex investigations.

The course has been developed jointly by the National Examination Board in Occupational Safety and Health (NEBOSH) and the UK's health and safety regulatory body, the Health and Safety Executive (HSE). Additionally, it prepares candidates to produce a risk-controlling action plan and implement the plan to prevent the recurrence of similar incidents.
