Until the late 1980's it was believed that the mechanisms of electrical injury had been identified and thoroughly explored. In rare instances where people presented with symptomatology that was inconsistent with known mechanisms, the symptoms were thought to be of psychological (non-organic) origin. In the last two decades a broader set of symptoms has been found to be linked to contact with energized...
If one works in the world of electrical safety long enough, taking part in forensic investigations is almost inevitable. Whether one is investigating an electrical incident in-house, or investigating as an expert witness, the nature of forensic investigation is largely the same. Whether analyzing a product failure or advising an attorney, forensic investigations are driven by similar principles and...
Electrical safety starts with policy, continues with education, requires administrative vigilance, and becomes individual responsibility at all levels. Case studies in electrical injury will be presented herein as the basis for understanding concepts of design for electrical safety. Working on the assumption that all electrical injuries are preventable, they must also be foreseeable. Instances of...
Using geometric primitives, a three dimensional finite element model has been developed to assess the pathway followed by electric current during an electrical accident assuming the entry point for the current was on one hand. Results indicate that the area where the risk of soft tissue injury is greatest is in the wrist region. Current entry on the palm or finger fronts was found to be more likely...
Electrical injuries can produce physical, neurological, and neuropsychological sequelae that exist even in the total absence of a theoretical current path that includes the brain. Diffuse electrical injury (DEI) is a rarely occurring class of electrical injury (EI) that can occur even after low-voltage contact. The objective of the study was to compare the occurrence rate of symptoms reported retrospectively...
