Abstract
Poor workstation design in a manufacturing facility negatively impacts the health and safety of workers, which hampers productivity. A systematic tool, Physical Demand Analysis (PDA), is utilized in a case-study project to quantify and evaluate physical labour and body posture for various production line tasks in a window and door manufacturing company. This paper presents the implementation PDA focusing on the design of the PDA form template, plant observation, and ergonomic risk identification. The data collection methodology and the implementation of time studies for plant observation are described. Four main ergonomic risks are identified: static whole body posture, manual material handling, sensory problem, and awkward body postures. Detailed observation findings, risk assessment method, analysis results and suggested corresponding corrective measures with regard to these four risks are described in this paper.

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
