12 Earthquake Safety A key aspect associated with the use of industrial equipment is the ability to withstand damage caused by seismic events. Many geographic locations where GE Flywheel systems will be installed are in active seismic zones. The Uniform Building Code rates geographic seismic zones on a scale of 0 through 4. Industrial equipment is susceptible to various types of damage as a result of an earthquake, which include but are not limited to: Water damage Toppling or overturning Equipment especially susceptible to toppling over are those with an aspect ratio of greater than 2:1. That is, if the equipment s height is greater than twice its width or depth, it is prone to toppling or overturning. Sliding against and striking other equipment and items Large or heavy equipment has significant momentum attached to it if it starts to move. Once it breaks inertia and begins to slide, it has the potential to cause serious damage to personnel and anything it strikes. Misalignment of components Refer to 2. - Site Preparation for details intended to securely fasten the GE Flywheel in its intended location for operational safety and seismic requirements Life Support Statement GE does not advocate the utilization of its products in any life support applications where a malfunction or failure of its products can potentially result in adverse effects to life support equipment or adversely affect the reliable operation and safety of life support equipment.
