A Risk Assessment Approach for Selecting a Replacement for Halon 1301 Fire Suppressant
Bibliographic record
Abstract
Halon 1301 has been the primary gaseous fire suppressant for total flooding applications on naval vessels since the mid 1960s. The speed and assurance of extinguishment has made it the popular choice, but other factors also contribute to its suitability as a fire suppressant. These factors include the ease of which the agent is dispersed, the minimal residue after release, its electrical non-conductivity and the minimal risk associated with short-term human exposure. Halons however, are ozone depleting substances and under the Montreal Protocol, production of these substances have been be subjected to a controlled phase-out. A number of Halon 1301 alternatives have been assessed using a risk analysis approach. The analysis comprised identifying suppressant selection criteria and rating the suppressants against each criterion and each criterion was rated on the basis of its level of importance in different applications. Rating both suppressant behaviour and the importance of each of the criteria ensures that the end use is given due consideration in suppressant selection.

How this classification was reachedexpand
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.
