Cummins Power Generation has released two downloadable documents and an online video about OSHPD (Office of Statewide Health Planning and Development) preapproval of emergency power generation systems. The California agency sets seismic requirements that critical equipment—such as emergency power systems—must meet before they can be installed in hospitals in the state. Cummins is the first manufacturer to earn OSHPD preapproval for its entire line of generator sets, as well as automatic transfer switches and digital master controls.
The OSHPD Overview provides a brief summary of OSHPD certification and preapproval, as well as what equipment from Cummins has been preapproved. The OSHPD White Paper is more detailed, exploring the relationship of the OSHPD standard to the International Building Code (IBC) and California Building Code (CBC) and also describes the kinds of testing required to earn preapproval.
A short OSHPD video includes footage of a 2,000 kW, 35,000 lb generator set on the largest triaxial shake table in the U.S. The video also features commentary from representatives of the independent engineering firm that supervised the shake-table tests as well as the director of the Pacific Earthquake Engineering Research (PEER) Center, where the testing was conducted.
