TEACHING THE HIERARCHY WITHIN VARIOUS APPROACHES TO SAFETY
Bibliographic record
Abstract
This paper highlights examples of approaches to safety and illustrates how these approaches influence the implementation of the hierarchy of controls. The hierarchy of controls emphasizes the elimination or reduction of exposure to hazards by using the most effective controls in a hierarchical order. The five control measures, from most to least effective, are: elimination, substitution, engineering controls, administrative controls, and personal protective equipment (PPE). Undergraduate engineering students should be well informed about the hierarchy of controls, the order in which the controls are applied, and be able to justify why they applied a particular level of control. Teaching a hierarchical approach to safety also benefits undergraduate engineering students after they graduate. It is concluded that the educational training provided to an undergraduate engineering student should ensure that the hierarchy of controls is explained, and its application reinforced with engineering-specific examples throughout the undergraduate years.

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.
