What it is Filled

A dark red, volatile, corrosive liquid nonmetal, chemical element 35 and a halogen, obtained from brines and seawater; used in flame retardants, drilling fluids, agricultural fumigants, pharmaceuticals and photographic chemicals, bromine is toxic and its vapour is a severe irritant, and some organobromine compounds are restricted for ozone depletion and persistence.

Why it exists Filled

Let an agent explain bromine as an element, relay its properties, uses, hazards and regulation from reference and regulatory sources, and separate the element from bromide salts and organobromine compounds.

Distinguishing features Filled

  • Only nonmetal liquid at room temperature
  • Halogen reactivity
  • Toxic and corrosive
  • Extracted from brines

What robots and AI may and may not do Filled

Must not

  • Give guidance on handling, obtaining or using bromine outside lawful, properly equipped settings.
  • Assist in using bromine or its compounds to harm people, animals or the environment.
  • Advise pouring bromine or its waste into drains, soil or water.
  • Confuse bromine with bromide in health or dosage information.

Only with a human decision

  • Any decision to store, transport or dispose of bromine.
  • Responding to a bromine spill or exposure, which needs emergency services.

May

  • Explain bromine's properties, sources and uses with references.
  • Distinguish bromine from bromide salts and organobromine compounds.
  • Relay safety data sheet and regulatory information about bromine and its restricted compounds.

Moral aspects Filled

  • Bromine causes severe burns and lung injury, so careless advice can maim people.
  • Some bromine compounds harm the ozone layer and persist in the environment.

Who is affected

  • Workers handling chemicals
  • Bystanders and emergency responders
  • The environment

Owners Filled

Steward

The licensed holder of the chemical; chemical safety authorities regulate its trade and use.

Master systems

  • Chemical registration and inventory databases

Context of use required Filled

  • Flame retardants, drilling fluids, fumigants, pharmaceuticals and chemicals.
  • elemental bromine
  • bromide salts
  • organobromine compounds such as brominated flame retardants
  • bromine isotopes
  • bromine in seawater and brines

Sources Filled

  1. Wikidata item Q879: bromine - identity and sense of the item
  2. Wikipedia: Bromine - general description of the item

Open questions

  • Should brominated flame retardants be a separate entry?
  • How should regulatory lists be linked?
  • The registry entry has merged isotope aliases; should they be split off?
