Accident Investigation Question

I asked the following questions should appear on anaccident investigation report:
1. Did the employee commit an unsafe act? Yes No Explain
2. Was there an unsafe condition contributing to the accident? Yes NoExplain
3. Did the employee violate a safety rule? I received 16 responses.
The opinions varied and were equally divided. Some felt that these expressed an opinion and did not express fact and did not lead to the root cause of the others stated that they could express fact (while answering the questions what happened and why) and cited examples - insubordination, not knowing the rules, deliberate decision to take a short cut, debris on the floor, etc. As to the third question, wasthe rule written/procedural/oral was addressed as germanin. One response cited the labor code in CA which allowed this type of question and kept the answer confidential and away from public scrutiny. My opinion is, after reviewing the responses, they address three criticalelements of the overall investigation - behavioral, environmental, and managerial. When compared against rthe question of "Describe what happened?"they trigger the supervisor who is making the initial report into looking at the overall incident a second time looking for specific causes and therefore have a place on the report. I thank all those who provided input. The input has been shared with my safety committee.
