Meaning and scope

Definition

Containment is a spatial relationship in which an object lies within a separate physical boundary such as a vessel, frame, or enclosure. It does not determine confinement, control, hazardous material, or psychological restriction.

In more detail

It addresses only the inside-outside relation between an object and boundary. It is distinct from mere proximity, above-below placement, and simply being indoors.

Includes

  • An arrangement in which an object is inside a physical boundary

Excludes

  • Confinement, control, hazardous material, or psychological restriction

What this does not imply

  • Confinement, control, hazardous material, or psychological restriction

Variability

Boundary shape and openness can be adjusted separately.

Usage and adjustments

Usage

  • Use it for an inside-outside relationship

Distinguish similar expressions

  • Do not use it to indicate confinement or hazardous material

Typical uses

  • Place an object inside a vessel or frame

Possible failure modes

  • The object is merely placed nearby
