Abstract
Industrial machines are known to possess many hazards. There are many laws, regulations, standards and practices that aim at ensuring that machines are safe for different workers performing various tasks including operation and maintenance. Safeguards protect workers by stopping hazardous motion when actuated. Those safeguards are integrated into machinery using two widely used international standards for functional safety. However, these standards have some significant differences although they are both based on similar principles. This paper explores those differences and their potential impacts. Subjectivity in the specification and design of safety systems, based on the differences, can lead to different levels of reliability in the safety systems even when considering the same hazard zone of machinery based on which standard is used.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
