Incident Investigation Report Template
This free incident investigation report template gives EHS, HSE, and safety teams a consistent, professional way to investigate a workplace incident from the first facts through to root cause and corrective action. When an injury, near miss, property loss, or environmental release happens, the quality of the response depends on structure — and improvising a form under pressure is how key facts get missed. This template removes that risk: it walks an investigator through 10 sections, from an at-a-glance incident summary and the people involved, to a detailed description, the immediate actions taken, the evidence collected, a full root cause analysis, a corrective-action plan, and formal sign-off.
Crucially, it is built to find system causes, not blame. The root cause analysis section separates immediate causes from contributing factors and underlying root causes, and includes a ready-to-use 5 Whys table and a hierarchy-of-controls reference so the actions you plan are as reliable as possible. The result is an investigation record you can defend at audit, share as a lessons-learned document, and use to actually prevent the next incident.

What is an incident investigation report?
An incident investigation report is the formal record of what happened, why it happened, and what will be done to stop it happening again. It is the difference between logging an incident and learning from it. A good report captures the facts while they are fresh, traces the sequence of events, identifies the underlying causes rather than the surface symptoms, and assigns owned, dated corrective actions. Done well, it protects your workforce; done poorly, it becomes a filing exercise that leaves the same hazard in place. This incident investigation report template turns the process into a repeatable exercise any trained investigator on your team can follow.
How to use the incident investigation report template
- Start promptly — ideally within 24–48 hours, while evidence and memories are fresh.
- Complete the summary, people, description, and immediate-actions sections with facts, separating what was observed from what is inferred.
- Work through the root cause analysis: immediate causes, contributing factors by category, and the 5 Whys.
- Assign corrective and preventive actions using the hierarchy of controls, then obtain sign-off.
Match the depth to the severity: a near miss may need a single page, while a serious injury warrants the full analysis and management review.
What it aligns with
The template supports the corrective-action process set out in ISO 45001 (clause 10.2, nonconformity and corrective action) and includes a reporting checklist for common obligations such as OSHA recordkeeping and RIDDOR. It uses the standard hierarchy of controls — elimination, substitution, engineering, administrative, and PPE — so your actions favour the most reliable controls rather than defaulting to procedures and personal protective equipment.
Who should use it
This incident investigation report template suits EHS and HSE managers, safety officers, supervisors, and investigation teams across manufacturing, construction, logistics, energy, and process industries. It works for a single supervisor documenting a near miss and for a formal team investigating a lost-time injury or environmental release. Whether you are building an incident-management process from scratch or standardising one across multiple sites, it gives every investigation the same rigorous structure.
