Seismic requirements for electrical installations
Concern about earthquakes and their impact on buildings and facility operation is no longer limited to those regions of the United States, such as the West Coast, where seismic activity is common. Over the past decade, concern for those areas of the country that have always had the potential for a devastating earthquake—but rarely exhibited seismic activity—have increased.
Experience with earthquakes has shown that keeping buildings standing is necessary but not sufficient. Even if the building is structurally sound after a seismic event, it may no longer be able to function if its mechanical, electrical, plumbing and life safety (MEP) systems are damaged. This is especially true for critical facilities such as healthcare, communications and other emergency service facilities that need to be in operation after a major earthquake. Additionally, even though a building is still structurally sound following an earthquake, it may take a lot of time and money to restore the building’s MEP systems so that it can effectively function again.
