Cost-containment initiatives over the past several years have encouraged the move to more offsite technical support of outages in powerplants. More recently, Covid-19 travel restrictions have made onsite technical support difficult. Thus, offsite support via video-chat technology has become more common. This has encouraged discussions questioning the adequacy of such offsite support. Recently, a roundtable was convened on this topic on the website of the International Generator Technical Community (IGTC).  more
By some counts, says James E Timperley of J E Timperley Consulting LLC, over 300,000 electronic medical devices-such a pacemakers, defibrillators, cochlear, and neurostimulators-are implanted in Americans annually. Millions of these appliances are in service, covering all age groups in today's population. This means that perhaps 1% of all people entering a powerplant may have some kind of electronic medical device. Providing a safe working environment for these individuals is more important than ever.  more
