Most employers know they need to complete an OSHA 300 log entry when an employee is injured. Far fewer have a disciplined investigation process that gets to why the incident happened. The difference between those two organizations is measurable: companies that investigate incidents and near-misses — and act on the findings — have significantly lower rates of recurrence.
An incident investigation is not about finding someone to blame. It is about finding the system failures — the missing guard, the outdated procedure, the training gap — that allowed the incident to occur. Those system failures are your real corrective actions, and they are what will prevent the next injury.
Near-miss investigation is equally important. A near-miss is a free lesson: something nearly went seriously wrong, and you have the opportunity to fix it before someone is hurt. Organizations with high near-miss reporting rates typically have lower injury rates — not because they are less hazardous, but because they catch and fix hazards earlier.
Incident vs. Near-Miss — What to Investigate
Incident (Injury or Illness)
Any work-related event resulting in injury, illness, or property damage. OSHA 29 CFR 1904 requires recording work-related injuries and illnesses meeting specific criteria (days away from work, restricted duty, medical treatment beyond first aid, etc.). Severe injuries (hospitalizations, amputations, eye losses) require OSHA notification within 24 hours. Fatalities require notification within 8 hours.
Near-Miss
An unplanned event with no injury or property damage but the potential for either. Near-misses are not required to be reported to OSHA, but OSHA strongly encourages internal near-miss reporting programs and publishes its own near-miss form. Companies that investigate near-misses using the same rigor as injuries close hazards proactively.
Property Damage / Equipment Failure
Events that cause equipment damage or near-failure without injury. These are often treated as maintenance events rather than safety events — a missed opportunity. Equipment failures frequently precede injuries: the broken guard that did not cause an injury this time is a serious incident waiting to happen.
The 4-Step Investigation Process
Preserve the Scene
Immediately after an incident or near-miss, preserve the scene before anything is moved, cleaned, or repaired. Photograph or video the area from multiple angles. Mark the positions of tools, equipment, and any materials involved. For serious injuries, notify OSHA as required (severe injuries within 24 hours, fatalities within 8 hours) before changing the scene. The scene is your primary evidence source — once it is disturbed, critical information is gone.
Collect Information
Gather statements from the injured person (if able), direct witnesses, and anyone else with relevant knowledge — including supervisors who were not present. Collect statements as quickly as possible after the event while memories are fresh. Review relevant documents: the applicable procedure or work instruction, the most recent JHA or safety inspection, training records for those involved, and any prior reports for the same equipment or task. Photograph all relevant documents and physical evidence.
Analyze the Root Causes
Work backward from the immediate cause to identify contributing factors and root causes. Use the 5-Why technique: ask "why did this happen?" at least five times, drilling down past the immediate cause to the underlying system failure. Common root cause categories include: inadequate procedures, missing or defective equipment, inadequate training, supervision failures, and hazards not identified in the JHA. Most incidents have multiple contributing causes — document all of them.
Develop and Implement Corrective Actions
For each root cause identified, assign a specific corrective action, a responsible person, and a target completion date. Apply the hierarchy of controls: eliminate or engineer out hazards where possible before relying on administrative controls or PPE. Corrective actions that only retrain the employee without addressing the hazard or system failure will not prevent recurrence. After implementation, verify the action was completed and evaluate whether it was effective.
Filled-In Example: ABC Precision Manufacturing
Below is an incident investigation report from ABC Precision Manufacturing for a laceration injury that occurred during a tool change on a CNC lathe. This example illustrates how the investigation goes beyond the immediate cause to identify root causes and assign system-level corrective actions.
INCIDENT INVESTIGATION REPORT — IIR-2026-003
ABC Precision Manufacturing, LLC | Date of Incident: March 18, 2026
Investigator: Maria Gonzalez, Quality & Safety | Report completed: March 19, 2026
Immediate Cause
Employee contacted the edge of a used carbide insert while placing it into the used-insert bin. Employee was not wearing cut-resistant gloves at the time of the tool change.
Root Cause Analysis — 5-Why
- Why was D. Kim not wearing cut-resistant gloves? — Gloves were not within reach at the machine.
- Why were gloves not within reach? — Gloves are stored in the safety cabinet at the end of the aisle, ~15 meters from CNC Cell 1.
- Why are gloves not staged at each machine? — No standard specifies where PPE must be located; storage is informal.
- Why is there no PPE staging standard? — The JHA for CNC tool changes (JHA-012) specifies cut-resistant gloves but does not specify the gloves must be at the machine prior to starting the task.
- Root cause: The PPE requirement in JHA-012 was not translated into a specific pre-task setup requirement (gloves at machine before beginning tool change). The reliance on employee memory to retrieve PPE from a remote location created the gap between written requirement and practice.
Contributing Factors
- Insert handling insert tool was available but not specified as required in JHA-012 — only "recommended."
- Task performed near end of shift — employee reported being in a hurry to complete the setup.
- No immediate supervisor present during tool change.
Corrective Actions
| Corrective Action | Control Type | Responsible | Due Date | Status |
|---|---|---|---|---|
| Mount cut-resistant gloves dispenser at each CNC machine (eng. solution preferred over remote cabinet) | Engineering | Facilities / R. Haines | Mar 25, 2026 | Completed Mar 24 |
| Revise JHA-012: change insert handling tool from "recommended" to "required." Add pre-task setup checklist item: gloves at machine before starting. | Admin (document) | M. Gonzalez | Mar 25, 2026 | Completed Mar 24 |
| Retrain all CNC machinists on revised JHA-012. Effectiveness: all 4 employees demonstrate pre-task PPE setup before tool change. | Admin (training) | M. Gonzalez | Mar 28, 2026 | Completed Mar 27 |
| Add PPE staging check to weekly supervisor safety walk checklist | Admin | R. Haines | Apr 1, 2026 | Completed Apr 1 |
Effectiveness verification: April 15, 2026 — M. Gonzalez observed all 4 CNC machinists during tool changes. All 4 retrieved gloves from machine-mounted dispenser before beginning. No recurrence reported.
Connect Safety Incidents to Your ISO 9001 CAPA Process
Incident investigation corrective actions are just another form of CAPA — and they belong in the same system as your quality nonconformances. Training Tiger stores investigation reports as controlled documents and ties corrective action training directly to the employees who need it.
- →Store incident reports as controlled documents with version history and approval workflow
- →Assign corrective action training to affected employees — track completion and sign-off
- →Automatic retraining trigger when a revised JHA or procedure is published as a corrective action
- →Audit-ready safety training records — exportable for OSHA inspection or ISO 9001 surveillance audit
Frequently Asked Questions
What does OSHA require for incident investigations?
OSHA does not have a single standard requiring investigations for all general industry events, but 29 CFR 1904 requires recordkeeping of work-related injuries and illnesses. OSHA's general duty clause (Section 5(a)(1)) effectively requires hazard elimination — and failure to investigate incidents can be evidence of inadequate hazard management. Severe injuries must be reported to OSHA within 24 hours; fatalities within 8 hours.
What is a near-miss and why should it be reported?
A near-miss is an unplanned event that did not cause injury but had the potential to. Near-misses are leading indicators of future incidents — they reveal hazards before someone gets hurt. Organizations with strong near-miss reporting cultures consistently have lower incident rates. Each near-miss is an opportunity to fix a hazard at a fraction of the cost of an actual incident.
What is root cause analysis in an incident investigation?
Root cause analysis identifies the underlying system failures that caused an incident, not just the immediate trigger. The immediate cause of a laceration might be "employee contacted rotating blade." The root cause might be "no procedure requiring guard reinstallation after maintenance." Corrective actions at the root cause level prevent recurrence; actions at the immediate cause level (retraining) usually do not.
How does incident investigation relate to ISO 9001 Clause 10.2?
ISO 9001 Clause 10.2 requires investigation of nonconformities and implementation of corrective actions. Safety incidents are system failures that fit directly into the CAPA framework. Organizations that integrate safety incident investigation into their ISO 9001 CAPA process have a more complete management system and satisfy both OSHA expectations and ISO continual improvement requirements with a single process.
