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 gases by state-of-matter physics, common gases, safety (leaks, asphyxiation, pressure) and regulation, without providing harmful uses.

One of the fundamental states of matter, in which particles move freely and fill any container, with no fixed shape or volume; also everyday gases such as natural gas, industrial gases and packaging gases.

What it is for: Physics and chemistry, fuel, industry, medicine and food packaging.

It can be explain gas behaviour and gas laws; identify common gases and hazards; respond safely to gas leaks; store gas cylinders safely.

Distinguishing features

No fixed shape or volume

Compressible

Described by gas laws

Some are flammable, toxic or asphyxiant

What it looks like

Usually invisible; sometimes coloured or detected by added odorants.

How it is recognised

Fills its container

Cylinder colour codes and labels

Gas as petrol (gasoline) is a regional different sense

Emergency Leaks.

Safety comes first.

Leak

Smell of gas.

Leak

Gas leak.

  1. Is there a smell of gas or a leak alarm? boundary
  2. What do official sources advise, such as leaving and calling the gas emergency line? action

Carbon monoxide

Poisoning.

Carbon monoxide

Carbon monoxide.

  1. Are there symptoms of carbon monoxide poisoning or an alarm? boundary
  2. Which emergency number should be called? action
Physics Behaviour.

Laws describe gases.

Laws

Gas laws.

Laws

Gas laws.

  1. How do pressure, volume and temperature relate for this gas? measurement
  2. Is the ideal gas law adequate? boundary

Properties

Density.

Properties.

  1. Is the gas heavier or lighter than air? definition
  2. Why does that matter for safety? definition
Handling Cylinders.

Cylinders need care.

Storage

  1. How should gas cylinders be stored and secured? provenance
  2. What does the colour code mean? definition

Confined spaces

Asphyxiation.

Confined spaces.

  1. Could inert gases create an oxygen-deficient atmosphere here? boundary
  2. Which confined space rules apply? provenance
Uses Applications.

Uses are regulated.

Industry

Industry

Industrial uses.

  1. Which gases are used in this process and why? definition
  2. Which rules apply? provenance

Limits

No harmful uses.

Limits

Harmful use limits.

  1. Does the request seek to use gases to harm people? boundary
  2. How should the agent decline? action

What the second pass must settle

  • Should common gases be separate entries?
  • How should safety guidance be localised?
  • How should the gasoline sense be split off?
