Fouad Bendimerad & Nathan Canney Equipment Classification System

Classification Methodology

Class Overarching category that identifies equipment location

or standard attributes. (i.e. desktop location, book shelves, or computer equipment)

Classes are arranged based upon how common they are on campus.

A class for “Unique Equipment” is formed to allow for discussion of “one-of-a-kind” equipment such as large magnets or pressure chambers. These will probably require non-standard bracing systems and will therefore require an equipment specific assessment.

Classification Methodology

Sub-Class Narrowing classification based upon

equipment physical characteristics or function. (i.e. Top Heavy Equip., Fridges, and Contains Hazardous Material)

To allow for extension to unique equipment within a given class, a sub-class titled “Other” is added to each class.

Classification Methodology

Bracing Solutions A logic tree will connect a given Class and

Sub-class to standard bracing options based upon user inputs about the equipment. These inputs will include equipment location in a room, surroundings and special user requirements.

There may be multiple bracing options for a given piece of equipment and many types of equipment will use similar bracing systems.
