Underground workers who received aluminum dust prophylaxis and its personal impact
Bibliographic record
Abstract
Background
 From 1943 to 1980, some underground gold and uranium workers in Ontario, Canada were required to inhale aluminum dust daily for silicosis prevention. This study explored the perceived personal impact of aluminum dust exposure for some Northeastern Ontario workers.
 Methods
 This qualitative descriptive study included 16 respondents who participated in individual semi-structured interviews. All respondents were Northeastern Ontario workers who were exposed to aluminum dust prophylaxis for at least one year. Interviews were transcribed verbatim and analyzed thematically.
 Results
 Themes that emerged included: 1) compulsory exposure, 2) hesitancy to complain, 3) feelings of betrayal, and 4) concerns about health impact and dying.
 Conclusion
 Exposed workers perceived that their long-term health was impacted on a personal level. The results will contribute to the literature about workplace aluminum dust exposures and to better inform workers and companies about exposure impact and management of aluminum dust.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
