When an earthquake shakes unrestrained objects, they can slide, swing, overturn, or strike people or other objects. File cabinets, freestanding bookshelves, office equipment, and items stored on shelves or racks can all cause serious injuries by their movement during an earthquake.
Most injuries that occur during earthquakes are caused by the movement of the building’s contents, not by the movement of the building itself.
The Non-Structural Earthquake Seismic Bracing or Q-Brace program document provides guidance to campus departments to address non-structural seismic safety hazards. It was adopted from FEMA-74: “Reducing the Risks of Non-Structural Earthquake Damage”.
