A comparison of the fire suppression performance of compressed-air foam and foam-water sprinkler systems for Class B. hazards
Bibliographic record
Abstract
Fixed pipe compressed-air foam (CAF) systems have been developed over the past decade through a research collaboration between the National Research Council of Canada (NRCC) and the Department of National Defence. Prototype CAF systems have demonstrated, through full-scale testing [1-3], their superior fire suppression performance for controlling and extinguishing fires for a number of hazards, including flammable liquids. To date, however, no detailed comparison testing with other similar fire suppression systems for flammable liquids has been undertaken.Fixed pipe CAF systems represent a major innovation in fire suppression technology. By injecting air into a foam-water stream in a mixing chamber, a significantly superior foam is produced primarily as a result of uniform, small bubble sizes. That foam is transported through a piping system to rotary nozzles which distribute foam over a prescribed area. There are currently no specific fire suppression performance or installation standards for CAF systems; thus, to assess the new technology for potential applications, comparisons must be made using existing standards for similar fire suppression systems.

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.
