What it is Filled

Water frozen into a solid, forming at 0 degC at standard pressure, occurring as sea ice, lake and river ice, glaciers, frost, rime, hail and ice crystals; it is less dense than liquid water and floats.

Why it exists Filled

Let an agent handle ice by form, physics, uses and safety, including thin ice on water and icy roads.

Distinguishing features Filled

  • Solid water
  • Floats on water
  • Many natural forms
  • Slippery and hazardous

What robots and AI may and may not do Filled

Must not

  • Advise people that lake, river or sea ice is safe to walk on without official measurements.
  • Serve ice made from water not fit to drink.
  • Leave walkways icy or remove warnings where people can fall.
  • Misrepresent the state of glaciers or sea ice to support a claim.

Only with a human decision

  • Closing or opening ice to public use.
  • Directing a rescue of someone who has fallen through ice.

May

  • Report ice conditions, thickness and warnings from official sources.
  • Make and store ice for food and drink following hygiene rules.

Moral aspects Filled

  • People die each year falling through ice or slipping on it.
  • Melting glaciers and sea ice threaten water supply, coasts and Arctic communities.

Who is affected

  • People on or near ice
  • Arctic and mountain communities
  • Polar wildlife

Owners Filled

Steward

Nobody for natural ice; the person or business that makes or sells ice for food.

Standards and interfaces required Filled

  • Winter road maintenance standards
  • Food hygiene for ice used in drinks

Context of use required Filled

  • Climate systems, cooling, food preservation and winter activities.
