Nonstructural restraint belongs in both life-safety and service-continuity review. ## Source fact: [The U.S. Geological Survey’s earthquake guidance](https://www.usgs.gov/programs/earthquake-hazards/earthquake-facts-earthquake-fantasy) explains that structures and their contents can fail or fall during shaking and injure or kill people. Its preparedness steps tell readers to bolt bookcases, cabinets, tall furniture, and file cabinets to wall studs; brace or anchor heavy electronics and other heavy items; secure items that might fall; and brace overhead light fixtures. USGS also advises asking an engineer about the seismic safety of a home or business. The source identifies cabinets, heavy electronics, other heavy contents, and overhead fixtures as practical restraint concerns, but it does not provide a design for a particular rack, battery cabinet, raised floor, anchor, or supporting structure. Those details require site- and component-specific evaluation. ## Boundary Seismic demand, code, component weight and geometry, anchorage substrate, rack certification, floor system, overhead interaction, clearance, and importance factor are site-specific. Installation can affect fire ratings, electrical safety, warranties, access, cooling, and equipment replacement. A facilities handyman’s visual judgment is not a structural design. Applicable codes, authorities, landlords, equipment manufacturers, and qualified structural or seismic professionals must guide the work. ## Applicability questions - Which sites and rooms face relevant seismic demand under current local information and code? - What are the weights, centers of gravity, anchorage points, supporting materials, and clearances for each component? - Could one component fall onto people, block egress, damage another system, or sever power, cooling, fuel, network, or fire protection? - Are raised floors, overhead trays, busways, pipes, ceilings, and flexible connections included? - Who is qualified and authorized to design and inspect the restraint? ## DSE recommendation: Conduct a room-by-room inventory with facilities, safety, IT, and a qualified professional. Prioritize life-safety hazards and components whose loss stops essential services. Record make, model, dimensions, operating and service weight, mounting, substrate, utilities, nearby hazards, and required maintenance access. Review racks, cabinets, batteries, UPS equipment, screens, storage, portable spares, and overhead systems as an interacting assembly. Obtain engineered or otherwise code-compliant details appropriate to the component and site. Use approved hardware and installers; control drilling around post-tensioning, utilities, hazardous materials, and fire-rated assemblies. Inspect anchors, bracing, clearances, flexible connections, and workmanship before acceptance. Add a restraint review to moves, adds, changes, refreshes, and room renovations so later work does not defeat the design. ## Verification and evidence Keep the hazard inventory, professional calculations or details where required, product approvals, permits, installer qualifications, photographs, torque or inspection records, deficiencies, and closure evidence. After an earthquake or equipment move, restrict entry as safety authorities direct and inspect before relying on the system. Do not describe restraint as proof that equipment will operate after every earthquake; pair it with backup, recovery, and alternate-site planning. ## Official references - [USGS Earthquake Facts & Earthquake Fantasy](https://www.usgs.gov/programs/earthquake-hazards/earthquake-facts-earthquake-fantasy) ## Primary reference - Name: Earthquake Facts & Earthquake Fantasy - Authority: www.usgs.gov - URL: https://www.usgs.gov/programs/earthquake-hazards/earthquake-facts-earthquake-fantasy - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Restrain nonstructural technology equipment for the site’s seismic risk,” DSE Security, https://update.dsesecurity.com/updates/restrain-technology-equipment-for-seismic-risk/ Publishing principles: https://update.dsesecurity.com/updates/dse-updates-editorial-methodology/ Usage and citation policy: https://update.dsesecurity.com/usage/ Copyright © 2026 Detection Systems & Engineering.
