Abstract
Fluorine-free foams (FFFs) have been introduced as alternatives to aqueous film-forming foams (AFFFs), which are based on per- and polyfluoroalkyl substances (PFASs). However, adoption of FFFs remains limited due to the lack of universal drop-in replacements and limited data on their health and environmental impacts. This study examined incentives and barriers to implementing FFFs in Fire Training Facilities (FTFs) to support the transition away from PFAS-based products. A survey was conducted from September 2022 to December 2023 across the U.S. and Canadian FTFs, including state-funded facilities, metropolitan fire departments, airports, military, and industrial brigades. Developed in partnership with fire service organizations, the survey assessed current foam use, motivations for transition, and associated challenges. Of all FTF training with Class B foams, 38% reported using FFF products. Primary incentives included environmental and health concerns, safety, and regulatory pressures. Key challenges were transition costs, training requirements, and uncertainties around disposal of foams. These findings highlight that while momentum toward FFF adoption is evident, ensuring products are genuinely PFAS-free and providing comprehensive training will be critical for effective, large-scale implementation. Fire training facilities can play a pivotal role in guiding this transition.

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
