About 1 , 000 people in the United States die each year as a result . Most of these deaths are related to on-the-job injuries . [3]The danger from an electric shock depends on how high the voltage is . Generally speaking , low voltage electricity does not normally cause significant injury to humans , but exposure to high voltage electricity probably results in serious damage .
