Understanding and Preventing Electrocution When Using Aerial Devices and Digger Derricks

Lineworkers face the ever-present danger of electrocution as they work on or near electrical components. It is important and absolutely necessary to follow your employer's work rules, ANSI NESC requirements, OSHA regulations and the equipment manufacturer's information to reduce the chance of serious injury or death.  

Electrocution occurs when a person’s body is a path for electric current. The body becomes a path by touching, or getting too close to, two objects at different potential (voltage). The voltage difference causes the current flow. You do not have to touch an object to be a path. The electric current can jump through the air if the distance, voltage, and weather conditions qualify.
