On March 20, 2009 a Los Alamos National Laboratory electrician received a 3570 VDC electrical shock, and received 1st and 2nd degree burns. The worker inadvertently contacted the high-voltage end of the 7 battery (510 VDC each) series string while performing what was assumed to be low-voltage, nonhazardous work. This event scored a 2750 using the Electric Severity Measurement tool, where a score of 330 qualifies as a serious electrical event. The report noted that substantial DC current effectively overloads the bodys nervous system pathways and blocks nerve transmission. This results in a paralysis effect, or the inability to effectively transmit signals to the muscles, and thus an inability to effectively move.
