Semi-formal axiom (Aristotelian)
Axiom type
LLM classification basis: function-based → ≡
A flame arrestor is defined primarily by its safety function - preventing flames from entering a system. Any physical mechanism (metal mesh, ceramic elements, packed beds) that achieves flame arrest can instantiate this type. The identity is given by the FlameArrestFunction, not by a specific structural configuration.

Identity-Giving Function

FlameArrestFunction → FlameArrestProcess
▼
COPI-Core operation
⚠ Process parent
PlannedProcess reaches no COPI-Core operation, and no gap (out of scope / coverage gap) is recorded.
LLM rationale:
The identity-giving function is flame arrest - preventing flame propagation from entering a system through an opening. This is a specific safety function that distinguishes flame arrestors from other safety devices or flow control equipment.

Genus Proximus

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
No appropriate domain superclass exists in the parent candidates. While 'ARRESTOR' appears in the hierarchy, it's too generic. 'ARTEFACT' is too broad. The concept requires a new intermediate genus 'SafetyDevice' for protective equipment, which would be a MaterialArtifact since flame arrestors are typically unitary devices installed in piping systems.

Flame Arrestor
from sibling classes under genus

Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The differentia specifies the flame arrest function and gas flow processing capability that distinguishes this from other safety devices under the same genus.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
These are the minimal essential parts - the functional arrest element and the structural housing to contain it and connect to the system.

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Flame arrestors process gas flows by removing flame fronts while allowing normal gas passage. The transformation is specifically flame extinguishment through physical mechanisms.
