Read enough incident reports and a pattern appears. Something went wrong, someone was involved, and the report concludes with two words: human error. A warning letter is issued, a toolbox talk is held, and the file is closed. Months later, something very similar happens to someone else.
Why human error is not a root cause
People do make mistakes. But a finding of human error only describes what happened. It does not explain why a capable, trained person did something that, afterwards, looks obviously wrong. Until that question is answered, nothing has been learned that will stop the next person making the same move.
In almost every case the answer lies in the conditions around the person: a procedure that did not match how the job is really done, two valves that look identical and sit side by side, time pressure from a shutdown running late, a missing tool that made the shortcut the only practical option, or a supervisor who was covering three jobs at once.
Questions that move an investigation forward
- What did the person believe was happening at the time? Decisions make sense from the inside. Find out what information they had, not what information you have now.
- Was this the first time, or the first time it went wrong? Many incidents follow a workaround that had been used safely for months and had quietly become normal.
- What made the correct action harder than the wrong one? Look at equipment design, labelling, access, lighting, workload and tools.
- What would stop anyone making the same mistake? A good corrective action works regardless of who is doing the job.
- Were there earlier warnings? Near misses, complaints and minor damage often point at the same weakness long before the serious event.
The corrective action test
Look at the actions coming out of your last few investigations. If most of them are retraining, reminders and disciplinary steps, the system is correcting people rather than conditions. Strong actions change the work itself: they remove the hazard, redesign the equipment, fix the labelling, or change the procedure so that the right way is also the easy way.
Why this matters for reporting
When investigations end in blame, people stop reporting near misses, and the organisation loses its best early warning. When investigations look for conditions rather than culprits, reporting goes up, and the problems get found while they are still small.
Are Your Investigations Finding Causes or Finding People?
Our HSE team leads and supports incident investigations using structured root cause methods, and helps organisations build investigation and near-miss reporting systems that produce corrective actions that actually hold.
