Improving Machinery-Related Risk Identification and Estimation with Accident Reporting and Logical Analysis of Data
Bibliographic record
Abstract
Continually managing occupational risks is the cornerstone of any prevention program. ISO 12100:2010 defines risk in the field of safety of machinery as the combination of the probability of occurrence of harm and the severity of that harm. The means available to help with risk identification present the hazards isolated from one another. Moreover, estimation of probability is a recurrent problem. To overcome these issues, this paper proposes a method using logical analysis of data to generate patterns from belt-conveyorrelated accident investigation reports. The patterns represent accident scenarios involving combinations of hazards and risk factors. The probabilities of the patterns are estimated to establish a hierarchy of prevention measures that will be part of a prevention action plan. Updating data from accident reports impacts risk estimation, thus entailing adjustment of the prevention action plan.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
