Learn the CCOHS definitions, why near misses matter, and how to investigate both. [ David Brennan EMBA, COHS ](https://www.safetyevolution.com/blog/author/david-brennan-emba-cohs) Apr 22, 2022 --- *Last updated: April 2026* **⚡ Quick Answer** - An incident is any unplanned event that could cause harm. An accident is an incident that caused injury, illness, damage, or loss. - If you investigate only accidents, you miss early warning events and allow repeat hazards to mature into serious outcomes. - Near misses are low-cost learning opportunities. Ignoring them is a high-cost strategy. - **Behind on incident follow-up?** [Start your 30-day free trial](https://www.safetyevolution.com/trial-offer) to track owners, deadlines, and closure proof in one workflow. Teams often use incident and accident as interchangeable words. In safety management, that confusion creates blind spots. Clear definitions drive better reporting, faster learning, and stronger prevention. ## Incident vs Accident: Operational Definitions **Incident:** Unplanned event with potential to cause injury, illness, damage, environmental impact, or business disruption. **Accident:** Incident that resulted in actual harm or measurable loss. **Near miss:** Incident with no immediate harm but clear potential for severe outcome. ## Why You Must Investigate Both - **Incidents reveal system weaknesses early.** - **Accidents reveal consequence when controls fail.** - **Near misses provide prevention data before injury cost.** If your process starts only after injuries, your lagging indicators are already telling you prevention failed. ## A Practical Investigation Model ### Step 1: Stabilize and preserve facts Secure area, capture timeline, and document objective conditions immediately. ### Step 2: Classify event type consistently Use one event taxonomy for incident, accident, and near miss to maintain trend quality. ### Step 3: Map control failures Identify what failed in planning, supervision, equipment, communication, or competency. Not sure where incident investigations are breaking down? Track findings, assign corrective owners, and verify closure before hazards repeat.

Actions should change controls, not only behavior reminders. ### Step 5: Verify corrective effectiveness Close action only when evidence confirms risk reduction in the field. ## Near Miss Reporting That Actually Produces Value - Make reporting fast and non-punitive. - Review near misses weekly with operations leadership. - Convert recurring near misses into targeted control upgrades. - Feed lessons directly into toolbox talks and pre-task planning. ## Metrics to Track After Every Event - Time to first response and stabilization. - Time to investigation completion. - Corrective action closure time. - Repeat event rate by hazard category. - Overdue corrective actions over 30 days. Still chasing incident records across files and inboxes? Centralize incident logs, corrective actions, and closure evidence so lessons stick.

An incident is any unplanned event with potential for harm, while an accident is an incident that resulted in actual injury, damage, or loss. ### Should near misses be investigated? Yes. Near misses are early warning signals that help prevent serious future accidents when investigated and corrected. ### How fast should corrective actions be closed? Prioritize closure speed based on risk severity, with critical actions escalated immediately and tracked to verified completion. ### What is the biggest investigation mistake? Stopping at worker error and failing to identify the system control failure that made the event possible. ### How often should leadership review incident trends? At least monthly, with weekly review of high-risk events and overdue corrective actions. ## Sources - [OSHA Recommended Practices for Safety and Health Programs](https://www.osha.gov/safety-management) - [OSHA Recordkeeping and Incident Guidance](https://www.osha.gov/recordkeeping) - [CCOHS, Health and Safety Programs](https://www.ccohs.ca/oshanswers/hsprograms/) - [CCOHS, Hazard Identification and Risk Assessment](https://www.ccohs.ca/oshanswers/hsprograms/hazard_risk.html) - [NIOSH Safety Research](https://www.cdc.gov/niosh/) - [CCOHS Newsroom](https://www.ccohs.ca/newsroom/) [Health & Safety Program](https://www.safetyevolution.com/blog/tag/health-safety-program) [Incidents & Near Misses](https://www.safetyevolution.com/blog/tag/incidents-near-misses) ## Similar posts Safety Culture ### [Human Error: The Leading Cause of Construction Accidents](https://www.safetyevolution.com/blog/human-error-cause-of-construction-incidents) Discover why human error is the leading cause of construction accidents and how contractors can use incident investigations and safety culture to...
