Overview

We humans are more conductive than the ground we stand on, which means that if there is no other easy path, electricity will make a path through our bodies. When we become part of the electrical circuit, the consequences are never good for us. Electricity is a serious workplace hazard that can cause falls and burns, and do major damage to our internal organs. It should come as no surprise that the word “electrocution” is derived from "electro" and "execution" - electrocution is death caused by electric shock.

It is not necessarily the number of volts that will electrocute you, but the amount of current, its path, and the time it takes to pass through your body.

Three rules from the general industry electrical standard are among Oregon OSHA’s top 25 violations every year:

  • 1910.303(b): Examination, installation, and use of equipment
  • 1910.305(b): Wiring requirements for cabinets, boxes, and fittings
  • 1910.305(g): Wiring requirements for flexible cords and cables

An arc flash is the sudden release of electrical energy through the air when a high-voltage gap exists and there is a breakdown between conductors. An arc flash gives off thermal radiation (heat) and bright, intense light that can cause burns.
