The study is part of a multi-year program aimed toward reducing earthquake risk for critical facility equipment and components. For each major system (e.g. fire response, emergency power, uninterruptible power supply (UPS), HVAC, etc.), logic diagrams were developed. Several key equipment systems were also selected for a detailed investigation of their performance in past earthquakes, to document observed vulnerabilities of typical components and the demonstrated effects of those vulnerabilities on system functionality.
