Purpose and description
Enable an agent to recognise a flame-bearing lighting torch, assess its condition and surroundings, and determine whether it may be carried, lit, used or extinguished.
A torch is a portable lighting implement that produces an exposed flame by burning fuel held at the end of a handle or supported by a handheld body.
It can be Classify a candidate as a flame-bearing lighting torch or flag a conflicting sense.; Inspect the grip, burning head, fuel load and attachment before selecting a unit.; Assess whether illumination, duration and permitted orientation suit a proposed use.; Determine whether documented conditions permit ignition, carrying or temporary mounting.; Select a documented extinguishing method and verify the subsequent heat state.; Determine whether a cooled unit may be replenished, repaired, stored or retired..
Distinguishing features
Produces its intended light from a supported flame rather than an electric emitter.
Provides a handle or shaft intended to separate the user's grip from the burning head.
Is designed to function as a portable flame-bearing implement, even when used in a temporary holder.
Uses flame primarily for illumination or display rather than directing process heat onto a workpiece.
Must be distinguished from a candle or lantern through its grip, burning-head arrangement and intended handling, rather than appearance alone.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 16 findings · 30 questions.
Identity and lighting role Establishes which meaning of torch applies and the lighting role being assessed.
The name alone cannot distinguish a flame-bearing implement from a flashlight or a process-heat tool.
Registry sense
Resolves the intended concept before applying combustion-specific characteristics.
Flame-torch boundary
Record evidence that this entry denotes a portable flame-bearing lighting implement.
- Does the originating registry record identify a flame-bearing torch, an electric flashlight or a process-heat torch? provenance
- Which combination of burning head, grip and intended use separates this torch from a candle or lantern? boundary
Intended lighting task
Separates usable illumination from uses that primarily require a visible flame.
Illumination or display
Record whether the torch must reveal surroundings, mark a position or present a flame for display.
- What must a user be able to see, or what flame display must be maintained, during the intended use? definition
- What observed illumination or flame visibility demonstrates that this task is met? measurement
Burning head and fuel path Describes the parts that hold fuel, sustain combustion and attach the flame source to the shaft.
A consumable solid head and a reservoir-fed wick require different condition checks and replenishment decisions.
Head construction
Records the burning assembly and how it remains attached as fuel is consumed.
Head retention
Assess the attachment and condition of fuel-bearing material, wick supports and other head components.
- What holds the burning head to the shaft, and which parts are intended to be consumed or replaced? definition
- What looseness, deformation or material loss makes the head unsuitable for ignition or carrying? action
Fuel storage and feed
Records fuel compatibility, loading and the route by which fuel reaches the flame.
Compatible fuel loading
Link the torch to supported fuels and loading limits appropriate to its actual construction.
- Which instructions or other reliable records establish compatible fuel and the loading method? provenance
- How much fuel is present, and what documented capacity or loading limit applies? measurement
- What evidence of leakage, saturation or obstructed fuel delivery prevents use? action
Flame and light performance Captures transitions into and out of burning and the light sustained during operation.
Torch suitability depends on flame behaviour and useful duration under stated conditions.
Ignition and burning state
Identifies ignition provisions, available controls and observable flame conditions.
Flame state recognition
Record how burning starts, how it can be controlled and how abnormal combustion is recognised.
- What documented ignition method and any flame controls, shutoffs or protective mechanisms does this design provide? action
- Which observations distinguish intended burning from smouldering, unstable flame or combustion outside the intended head? definition
Light output and endurance
Relates useful light and burn duration to fuel loading and operating conditions.
Usable light duration
Assess how long the torch meets its lighting task rather than merely retaining a flame.
- What illuminance is measured at the intended task distance and direction? measurement
- For a stated fuel load, orientation and wind condition, how long does the torch maintain the required illumination or display? measurement
Carrying, mounting and surroundings Assesses the relationship between the burning torch, its support and nearby people or materials.
Moving or tilting a supported flame introduces constraints that a lighting-output description cannot capture.
Grip and support
Records handling geometry, grip condition, orientation limits and holder compatibility.
Supported burning position
Determine whether a hand or holder can maintain the torch in its documented operating position.
- What are the loaded mass, usable grip length and separation between the grip and burning head? measurement
- Which carrying orientations and holder arrangements are supported by the design instructions? action
- What grip damage or attachment movement would prevent maintaining that position? action
Exposure and use location
Connects flame, emissions and environmental exposure to a proposed location.
Location suitability
Record the evidence needed to judge clearance, ventilation, weather exposure and local permission for use.
- What documented restrictions address nearby combustible material, overhead obstructions, ventilation and wind? provenance
- Do the proposed route or mounting location satisfy those restrictions throughout use? action
- Which applicable standard, issuing body, certification requirement or venue rule governs this particular torch use? provenance
Extinguishing and return to service Covers stopping combustion, assessing residual heat and preparing the torch for its next disposition.
An extinguished torch may still contain hot material or remaining fuel, and different head designs have different service paths.
Extinguishing and cooling
Distinguishes flame extinction from a verified condition suitable for subsequent handling.
Verified extinction
Identify the compatible extinguishing method and evidence that flame, embers and residual heat have been addressed.
- Which extinguishing method is documented for this fuel and head arrangement? action
- What observations or temperature checks establish that combustion has stopped and the torch is ready for the proposed next action? measurement
Consumables and retirement
Determines whether the head and fuel system can be replenished or must be replaced or retired.
Next-use readiness
Assess cooled components, remaining fuel and service instructions before storage or another use.
- Which cooled components may be cleaned, replenished or replaced, and what instructions establish the procedure? action
- What damage, contamination or consumption requires retiring the head or the whole torch? action
- What documented storage or disposal requirements apply to remaining fuel and spent head material? provenance
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

- Does an existing Vercy world model already own this concept, requiring a link instead of a separate publication?
- Which fuel-bearing head and reservoir-fed variants belong within the confirmed registry boundary?
- Which authoritative sources establish applicable standards, certification requirements and use restrictions for the included variants?
- What sourced dimensions, fuel capacities, light measurements, burn durations and failure observations can establish representative ranges without implying universal limits?
