The Tools and Equipment hierarchy contains terms for equipment used in processing materials and fabricating objects, as well as terms associated with activities and disciplines in the construction industry, design professions, the fine and decorative arts, and other aspects of material culture. Excluded are terms for objects such as measuring devices and weapons, which may be considered equipment but fall into the scope of other hierarchies in the Furnishings and Equipment section of the Objects facet. Relation to other hierarchies: Terms for devices used to measure in terms of standard units or fixed amounts (e.g., "gauges") are in the Measuring Devices hierarchy. Terms for items that are necessary to anchor or join materials, objects, or components (e.g., "nails," "buckles") appear in the Components hierarchy. Terms for constituent parts of equipment (e.g., "handles") are also in the Components hierarchy. HVAC systems can be found in the Object Groupings and Systems hierarchy, while the terms for HVAC equipment (e.g., "air conditioners") are found here.
