Document Summary
Types of electrical injuries: electrocution (death due to electrical shock, electrical shock, burns, falls. Conductors: substances, such as metals, that have little resistance to electricity. Insulators: substances, such as wood, rubber, glass, and bakelite, that have high resistance to electricity. Grounding: a conductive connection to the earth which acts as a protective measure . *ma = milliampere = 1/1000 of an ampere. Electrical burns: most common shock-related, nonfatal injury, occurs when you touch electrical wiring or equipment that is improperly used or maintained, typically occurs on the hands, very serious injury that needs immediate attention . Falls: electric shock can also cause indirect or secondary injuries, workers in elevated locations who experience a shock can fall, resulting in serious injury or death.
