What it is Filled
A form of matter with constant chemical composition and characteristic properties, such as an element or compound, identified by name, formula and registry numbers, and regulated for safe production, transport and use.
Why it exists Filled
Let an agent handle chemical substances by identity, properties, hazards, regulation and safe handling, without facilitating harmful uses.
Distinguishing features Filled
- Defined composition
- Characteristic properties
- Registered and classified
- Hazards communicated by labels
What robots and AI may and may not do Filled
Must not
- Assist in making or using any substance to harm people, animals or the environment.
- Mix, store or dispose of substances against their safety data sheets.
- Mislabel a substance or remove hazard labels.
- Ship or transfer substances in breach of transport or control rules.
Only with a human decision
- Handling, mixing or disposing of hazardous substances.
- Releasing a substance into the environment.
May
- Identify substances by name, formula and registry number, citing safety data sheets.
- Report hazard classes and handling rules from official classifications.
Moral aspects Filled
- Chemical exposure harms workers and neighbours, often long after the event.
- Hazard information must reach everyone who handles a substance.
Who is affected
- Workers
- People near storage and transport
- Ecosystems
Owners Filled
Steward
