smoke
Let an agent handle smoke as an aerosol with sources, composition and serious health and safety effects, including fire smoke, tobacco smoke and deliberate smoke uses.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle smoke as an aerosol with sources, composition and serious health and safety effects, including fire smoke, tobacco smoke and deliberate smoke uses.
A suspension of fine solid and liquid particles and gases produced by combustion or heating, such as from fires, tobacco, engines or smoke generators.
What it is for: Smoke is mostly an unwanted product; it is also used for signalling, screening, flavour and testing.
It can be detect it, with smoke alarms; avoid and escape it, in fires; measure it, as particulate matter; use it deliberately, in smoke screens, security fog or cooking.
Distinguishing features
Produced by combustion or pyrolysis
Contains toxic gases such as carbon monoxide and hydrogen cyanide
The main killer in building fires
Magic smoke is electronics slang for component failure
What it looks like
Grey, white, black or coloured plumes that reduce visibility and carry an odour.
Physical character
particle size: 0.01-1 micrometres - mostly fine particles
carbon monoxide in fire smoke: up to several percent volume - lethal concentrations possible
How it is recognised
Visible plumes and haze
Smell of burning
Colour hints at what is burning but does not identify it

Source and composition Where it comes from and what it contains.
Source decides composition and hazard.
Source
What is burning.
Source
The source of smoke.
- What is producing the smoke? definition
- Is it a fire that needs emergency response? action
Composition
Particles and gases.
Composition
Main components.
- What does this smoke contain? measurement
- Which components are most toxic? boundary
Fire safety Smoke in buildings.
Smoke kills more people in fires than flames.
Detection
Alarms.
Detection
Alarm provision.

- When were they last tested? provenance
Escape
Getting out.
Escape advice
What to do.
- What should people do if they see smoke: get out, stay out, call emergency services? action
- How does smoke control protect escape routes? definition
Health Exposure.
Short and long exposures both harm health.
Exposure
Levels and duration.
Exposure
Exposure level.
- How much smoke are people exposed to? measurement
- Which groups are most vulnerable? boundary
Protection
Masks, filters, staying indoors.
Protection
Protective measures.
- Which protective measures help against this smoke? action
- When should medical help be sought? action
Deliberate use Smoke on purpose.
Deliberate smoke has rules too.
Uses
Screens, security, cooking.
Use
The deliberate use.
- For what purpose is smoke being produced? definition
- Is it permitted here? boundary
Tobacco smoke
Smoke-free rules.
Smoke-free law
Rules on smoking.
- Where is smoking prohibited here? boundary
- What support exists to stop smoking? action
What the second pass must settle
- Should tobacco smoke and fire smoke be separate entries?
- How should wildfire smoke advisories be linked?
- What must an agent say first when someone reports smoke in a building?
