Stanford Nonstructural Hazard Mitigation Project Fouad Bendimerad & Nathan Canney Equipment Classification System April 3, 2009
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.
Classification System • Class I: Computer Equipment • Sub-Class A – Computer Equipment Racks • Sub-Class B – Desktop Computer Equipment • Sub-Class C - Other
